2024.05.19 19:19 No_Awareness_4626 Stremio works on iPhone / iPad without RD also !! You will need PC / Mac.
If you use your AR glasses with iPhone or iPad and use Stremio to stream unlimited amount of Movies and TV Shows from across all streaming services (or would like to) then this is an amazing news which I learnt recently. Though this has been there for ages. submitted by No_Awareness_4626 to rokid_official [link] [comments] I wasn’t able to stream movies and shows from Stremio on my iPhone and iPad because I am not a ReadDebrid Subscriber. So I used to use an old Samsung S10e phone or connect Rokid Station. Rokid station is a good standalone device but it uses android TV. And I wanted to somehow be able to use Apple TV experience. But Apple TV and iPhone / iPad don’t have Stremio app. We can access Stremio Web (by opening web.stremio.com) on Safari on iPhone / iPad. There is still no way to access Stremio directly on Apple TV. But there is a very nice way to stream movies and tv shows using Stremio web on iPhone if you have a Mac / PC. Here are the steps
But this method also is for content that is recent and has good number of Active peers. If you want old content that has very few peers then the only way is to use RD. Rokid Max + iPad + Stremio Web = Awesome. |

2024.05.19 16:32 jeffdeleon Royal Galaxy and Starborn Royalty Mod List Updated for 1.11.36 (Really fun patch!)
Hey all, submitted by jeffdeleon to starfieldmods [link] [comments] This patch isn't as bad for mods as many feared. It's relatively easy to get the game up and running and to start enjoying the new features. The main essential mod not updated is StarUI. I went throuhg the Starborn Royalty Mod List and made updates/substitutions where needed. Mods with an ** are not yet up to date, but I expect them to be updated soon. Abandoned mods not updated for this update have been removed. If you run EXE, you need to delete lasercutter.nif. Mods tweaking female armor need to be updated, but won't break your save or anything. Starborn Royalty - A Starfield Mod ListOld logo from promoting my writing career :PI added a new plugins.txt file to help guide you with load order. Royal Galaxy is an All-In-One for my mods, so if you run that, you don't need the other ones. *Royal Galaxy Vortex Collection not updated as too many of the included mods are still pending an update. Royal Galaxy only received minor updates and improvements as it worked out of the box with the latest patch. The way I mod is very simple and safe. This update was not required for this patch. The other versions works fine with this patch. I just made some tweaks, forwarded SFCP changes, and did small improvements where I could. As Bethesda made the game more fun for me, I'll be playing. I hope to finally get into my revision of the player dialogue in the Crimson Fleet and Ryujin quest lines, which I haven't particularly wanted to play through again. Royal Galaxy 2.50 - Massively Enhanced By Bethesda's Difficulty Configurators =)R.G !I've noticed many people either confused about what is contained in Royal Galaxy, or afraid that it is a massive mod that won't work with other mods. That couldn't be further from the case. I am a very Vanilla+ guy and I value compatibility above all. Over the many months I've been posting mods, I have had very few issues and user reports. This is because my mods only tweak vanilla records. This means they should be compatible with everything. I know the Creation Kit isn't out, and I certainly don't want to spend my time creating mods that end up breaking on a patch. As a result, I have stuck to what seems to be the safest method of modding via xEdit. Early reports of incompatibilities were caused by people ignoring directions and loading mods like craftable quality BEFORE Royal Galaxy rather than after. This new document attempts to break down the contents of Royal Galaxy into bullet points. I'll continue to update this as I remember the changes I have made. Modding Starfield was pretty much my full-time hobby this past year so the amount of work that went into tweaking everything is enormous. I tweaked, by hand, the inventories of specific NPCs to enhance the story, lore, ability to pickpocket, and difficulty of specific story encounters. Since Royal Galaxy is an AIO, it includes all the tweaks from the included mods. This old document includes all the bundled mods. In short, when you open up Starfield in xEdit, almost everything in the game is presented as tweakable, much like a config file. I went through the whole game and tweaked most things to be more fun and enjoyable and removed what I considered to be pain points. A few things I modded were more elaborate, like rebalancing Terromorphs, weapons, and redoing boring/useless weapon enchantments, but for the most part Royal Galaxy, and all my mods, are simple and safe. My biggest issue with my own work was the lack of easily-tweakable difficulty as some players found Royal Galaxy too hard. Bethesda did a fantastic job improving Royal Galaxy in the latest patch. =) In early game, you probably want incoming damage low and outgoing damage high. As you acquire more power, turn the difficulty up as much as you can. I think where people get confused is that I have so many mods posted, but also Royal Galaxy. My intention is that people can customize their game as much as they'd like. I think Royal Aliens, for example, is the de facto best alien overhaul by a ton. It is included in Royal Galaxy, but also maintained standalone for people who only want the aliens and otherwise like the game as-is or other modded ecosystems. There are a few pieces of Royal Galaxy that haven't gone standalone yet because life got busy and maintaining separate pages is difficult. I need to release the bundled Medicine overhaul standalone as that goes particularly well with the new survival. Next up should be Royal Combat Overhaul, which will bundle ONLY the combat portions of Royal Galaxy separately. https://preview.redd.it/7p2uqtd57e1d1.jpg?width=2560&format=pjpg&auto=webp&s=b4a1f1f4feac89617d2d9c52e05df65ae979a500 |

2024.05.19 15:17 Efficient-Flan-7455 How do I change a specific instance of a scene?
I'll keep this brief, but in short, I have 2 "text guys" who run a script to change the text of a globally loaded textbox scene which they then also cause to appear. What I want to do is have them change the text they add inside of these textboxes to unique lines, and maybe even change some of their appearances for different areas. submitted by Efficient-Flan-7455 to godot [link] [comments] The problem comes from the fact that I kind of don't want to make a new scene for each different "text guy" whenever they have a different text line, look, size, etc. As I think that'd be a bit much on my games performance / asset count, as I intend to have 10+ of these guys in the tutorial alone. So my main question is, how can I change the code of one specific instance, rather than making a new scene every time and changing the code that way? Textbox Code Text Guy Code.. Ignore the text, as its a placeholder haha |

Reviews🔗Royal Consumer 500DX Cash Register for Small Businesshttps://preview.redd.it/wctlejeqed1d1.jpg?width=720&format=pjpg&auto=webp&s=ed7d531bf7896343df44a326f8c386416d225cc2 As a small business owner, I can attest that the Royal 500DX Cash Register has been an absolute game-changer for me. The dual LCD displays provide clear visibility for both the clerk and the customer, making transactions seamless and efficient. One of the standout features is its capacity to handle up to 2,000 employees, which is more than adequate for a small to medium-sized business. Additionally, the unlimited messaging capability ensures that you won't miss any important announcements or updates. However, the product does feel a bit flimsy due to its predominantly plastic design, which might concern those who prefer a sturdier build. Another fantastic aspect of this cash register is the 999 Price Look-Ups, allowing for quick processing of transactions. Programming four different tax rates also makes the setup process incredibly straightforward. On the downside, the impact printer, although functional, occasionally feels outdated compared to more advanced models. Overall, the Royal 500DX Cash Register has proven to be a reliable and user-friendly addition to my small business. Its features cater to my daily needs and have undoubtedly contributed to the efficiency and success of my operations. 🔗Sharp XE-A102 Compact Electronic Cash Register with LED Displayhttps://preview.redd.it/4oocgzqqed1d1.jpg?width=720&format=pjpg&auto=webp&s=7f386a4da0393e5ba582f1e06dcfdd64b55e6e0e I have been using the Sharp XE-A102 Electronic Cash Register for a start-up retail business, and it's been a reliable and efficient partner. The compact design allows it to fit easily in our small store, and the bright LED display makes it easy for us and our customers to see the transaction details. The 8 departments feature helps us organize our inventory, and the 80 PLU/Items capacity allows us to input all our products without issues. One of the standout features of this cash register is its ability to accept different payment methods like cash, cheque, and credit card, which has made it easy for us to cater to our customers' preferred payment options. Additionally, the time and date display feature ensures that our transactions are accurate and timely. However, there are a few minor drawbacks to the Sharp XE-A102. It can be a little noisy and slow compared to some other cash registers, which may be an issue during peak hours when we need to serve customers quickly. Moreover, the instructions provided are quite small, making them difficult to read and follow. Overall, the Sharp XE-A102 Electronic Cash Register has been an excellent addition to our start-up retail business. Its compact design, 58 mm wide reliable printing, and ability to accept multiple payment methods make it a valuable tool for any small retailer. While it may have a few minor issues, the majority of users, including myself, are satisfied with its performance and recommend it to others. 🔗Professional XE Series Electronic Cash Registerhttps://preview.redd.it/63z5wl2red1d1.jpg?width=720&format=pjpg&auto=webp&s=838a61378141c4d4aaebc4a889e25d11c1c90157 I recently added the Sharp XE Series Electronic Cash Register to my tiny boutique store, and I couldn't be happier. Before settling on this model, I spent a lot of time researching various cash registers, but the XE Series stood out for its advanced sales reporting capabilities and seamless tie-in with QuickBooks Pro. The moment I unboxed it, I was impressed by its sleek, professional appearance and built-in SC card slot for easy connectivity and data back-up. Setting up the register was incredibly easy, and within just a few hours, it was ready to go. Its intuitive interface made training my employees a breeze. The thermal printer was a pleasant surprise; it's much quieter and faster than traditional receipt printers. Plus, the customizable receipts with graphics and logos definitely give my store a professional edge. One of my favorite features is the automatic tax system, which not only saves time but also reduces the potential for errors and makes reporting so much easier. The locking drawer ensures security and comes with multiple bill and coin compartments, making deposits a lot more organized. The only downside is the rather complicated user manual, which could definitely be improved. It's not a complete deal breaker, though, as there are plenty of helpful YouTube tutorials available online. All in all, I'm thrilled with my purchase of the Sharp XE Series Electronic Cash Register. It's a perfect fit for my small business and a real game-changer when it comes to streamlining sales transactions and accounting. I wouldn't hesitate to recommend this cash register to anyone running a small retail or service business. 🔗Casio Single-Tape Thermal Cash Register for Businesshttps://preview.redd.it/fj9sgulred1d1.jpg?width=720&format=pjpg&auto=webp&s=54574ad3b2350fad83a5af4e9ced9b7a3044e6a6 Casio's PCR-T280 is a fantastic single-tape thermal cash register that offers more functionality for medium-sized businesses than entry-level models. With the ability to track up to 1,200 price lookups, it offers a level of specificity in item sales tracking not commonly found in its class. It also allows businesses to track sales up to eight different operators, making it an excellent tool for business tracking and growth. One of the standout features of this product is its hygienic, antibacterial keyboard. In our current world, where cleanliness is paramount, this characteristic provides a measure of peace of mind for both business owners and customers alike. Furthermore, its multipurpose tray can hold money in four bill compartments and five coin compartments, ensuring the efficient flow of transactions. The PCR-T280 also boasts a high-speed thermal printer, which can be used either for customer receipts or as a journal printer for recording all the store's activities. Its mode lock with key control feature provides multiple operation positions through physical keys, providing a level of security usually found in more expensive models. Although it is not touch-screen, its simple and intuitive design makes it easy to program and use. Some users did find the manual a bit difficult to follow, but with a bit of practice, most find it quite manageable. With its ability to handle multiple sales tax needs and its capacity for PLU capabilities, the Casio PCR-T280 has proven itself as a reliable tool for various businesses, small or medium-sized. However, one minor drawback is the depth of the money/change drawer, which could have been a little deeper for added convenience. Despite this minor issue, the vast majority of users recommend this register for its performance and price point, providing an excellent value for businesses looking for an affordable, reliable cash register solution. 🔗Heavy-Duty Cash Register with Alpha Keyboard and LCD Displayhttps://preview.redd.it/rgcm3zured1d1.jpg?width=720&format=pjpg&auto=webp&s=e90611839a08205344996bd346c4f76bb8e15960 As an avid user of cash registers in my grocery store, I recently discovered the Royal Alpha 1100ml Cash Register, and my experience has been quite satisfactory. This heavy-duty register is perfect for my high-traffic establishment, offering a reliable and swift cash management system that I can always depend on. The first thing that caught my eye about this cash register was its single fast and quiet alphanumeric thermal printer, capable of handling over 1 million lines. It's been able to keep up with the constant rush of customers, making it a reliable addition to my store. The large 10-line LCD user display and alpha keyboard ensure easy programming, which was a breeze, even for a beginner like me. The SD Card slot is another excellent feature, enabling efficient accounting data transfers to a PC, a necessity for any modern business. However, I will say that the software included with the register can be a bit flaky at times. While it is supposed to read the x and z reports that the machine puts on the sd card, I sometimes find myself having to use the sd card to transfer report data manually. Additionally, getting in touch with their tech support doesn't seem to be very helpful, as they often provide no real technical assistance. Despite these minor issues, the Royal Alpha 1100ml Cash Register has been a solid addition to my store. Its heavy-duty locking cash drawer with four slot bill and removable five slot coin tray, along with its automatic tax computation, has made managing funds and keeping track of sales much easier for me. If you're in need of a reliable cash register for your business, I'd highly recommend giving this one a try. 🔗Fast and Accurate Cash Register System with Thermal Printing and 8-Line Displayhttps://preview.redd.it/qu5h8dbsed1d1.jpg?width=720&format=pjpg&auto=webp&s=cbccc254fa34615f87dd2812357e0f2a57027db4 I recently discovered the Sharp XEA407 Cash Register while searching for a reliable and feature-rich solution for my little grocery store. After trying it out, I must say it's exceeded my expectations. The first thing that impresses anyone who lays their eyes on it is the sleek eight-line display. It's not just a pretty face though; it's got brains as well with 7000 Price Lookups (PLU's), allowing quick and accurate entry. The inclusion of 99 departments is brilliant as it makes managing diverse product types a breeze. My favorite feature? Hands down, the microban keytops. They provide built-in antimicrobial protection, keeping those pesky germs at bay, which is particularly important given the current health situation. And let's not forget about the large 32GB SD card slot for computer connectivity and data storage. However, there were a few hiccups too. The lack of French documentation was a letdown for me, a French-speaking Canadian. Plus, a few customers have reported missing parts upon delivery, making the product unusable. So, while there are some minor issues, the Sharp XEA407 Cash Register has overall been a reliable and efficient addition to my store. It's fast, easy to set up, and offers more than enough features for most small businesses. If you're looking for a cash register that combines modern tech with dependability, this might just be the one for you. 🔗Royal 100Cx Portable Battery/AC Powered Cash Registerhttps://preview.redd.it/mpye61nsed1d1.jpg?width=720&format=pjpg&auto=webp&s=53410d259f67c2fbda2560e107147dca104e0317 As a small business owner, I've been on the hunt for a reliable, portable cash register to make sales easier at my farmer's market stand. The Royal 100Cx, with its compact design and battery-powered operation, has been a reliable companion for me. The automatic tax computation feature is a game-changer, allowing me to easily manage sales and taxes on-the-go. However, the initial setup can be a bit daunting, and the manual doesn't do a fantastic job of explaining everything. The preset department pricing and sales analysis by category of merchandise are standout features that have helped me keep track of inventory and sales trends. It's crucial for businesses like mine, where inventory and sales fluctuate frequently. The ink roll printer provides a receipt printout, providing a professional touch to every transaction. In terms of drawbacks, one thing to note is that the tax computation is limited to only four rates – VAT, Canadian, and a couple of others – which may not cater to everyone's business needs. However, for my small farm market business, it's more than sufficient. Overall, the Royal 100Cx is a dependable piece of hardware, and it's been a significant asset in streamlining my sales process. It may have a slightly steep learning curve, but once mastered, it's a powerful tool for any small business seeking a portable, autonomous cash register solution. 🔗Royal 435dx Cash Register with 16 Department Capability and 8 Clerkshttps://preview.redd.it/txxdg61ted1d1.jpg?width=720&format=pjpg&auto=webp&s=164bcd3d5dc97bc9b7528ca1c00673134ce19862 As a small business owner, I can attest to the convenience of the Royal 435dX Electronic Cash Register in my daily operations. Its 16 departments and 800 PLU's ensure an efficient flow of transactions, while the 8 clerk capacity and 4 tax rates enable seamless management, even for those serving in various locations or catering to international clientele. One of the highlights of this cash register is the front and rear LCD displays, allowing both the clerk and customer to see each transaction clearly. The memory protection with backup batteries provides added security to safeguard data in case of a power outage, a particularly valuable feature for businesses operating in areas with unpredictable power supply. However, a minor con would be the single station 57mm impact printer, which could limit the pace of transactions during peak rush hours. Also, the locking cash drawer tends to be a bit cumbersome, requiring more time than necessary to retrieve and return change. Despite these minor drawbacks, the Royal 435dX Electronic Cash Register has significantly improved my business operations, allowing me to keep track of transactions efficiently, even during peak hours. I would recommend this cash register to other small business owners looking for a reliable and feature-rich option that delivers exceptional performance at an affordable price point. 🔗Casio SE-S700 Cash Register: High-Speed Single-Station Thermal Printerhttps://preview.redd.it/v48cimbted1d1.jpg?width=720&format=pjpg&auto=webp&s=9147acc58257ad1b649fd63e1da8c960a9a87046 I recently upgraded my old, heavy cash register to the Casio SE-S700, and I must say, it has made running daily transactions a breeze. The built-in rear customer display ensures that prices are accurate, while the 8 department keys and 999 PLUs make it a cinch to organize my inventory. One of my favorite features is the customizable receipt header, allowing me to print unique messages on each customer receipt. The large, easy-to-read LCD display ensures that no mistakes are made during sales transactions. However, there are a few cons to consider. The plastic construction doesn't instill much confidence in its durability, and I wish the cash register drawer featured a more secure locking mechanism. Overall, the Casio SE-S700 has proven to be a reliable and efficient cash register for my small business, saving me time and preventing any hassles when it comes to handling transactions. 🔗Clover Station POS System with Cash Registerhttps://preview.redd.it/01ab3vrted1d1.jpg?width=720&format=pjpg&auto=webp&s=0dc914dd36488d910cdfc6d729888d81d4bd956f I recently picked up the Clover Station POS System for my little cafe, and it's been quite the rollercoaster ride. Imagine a sleek, brushed aluminum body with a 11.6" touchscreen display that's as responsive as a well-trained puppy. Sounds appealing, right? Well, it is. But let's dive a little deeper. First off, the touchscreen is large and bright, perfect for both me and my customers to navigate. The high-resolution camera embedded within the system makes scanning barcodes or QR codes a breeze, which is super helpful for keeping track of inventory. Plus, the swivel arm swivels smoothly between my side and the customer's, making transactions feel seamless and personal. However, there have been some hiccups. For one, the single power source for the display and printer can create a tangled mess of cords, especially when you're trying to juggle other peripherals. And while the connectivity options (Ethernet, Wi-Fi, and Bluetooth) are great, I sometimes find myself struggling with Wi-Fi lags. Moreover, the customer service has proven to be quite the challenge. You see, I bought the Clover Station from a seller who didn't provide much support. When things went awry, I was left to figure it out on my own. Needless to say, getting in touch with their customer service has been a nightmare. It feels like they're speaking a different language sometimes, and getting a call back is as rare as a winning lottery ticket. Despite these cons, I still find the Clover Station POS System useful for my small cafe. It's a stylish, reliable system that offers a range of features and connectivity options. However, be prepared for the occasional frustration and confusion, especially when it comes to their customer service. In conclusion, the Clover Station POS System is a mixed bag. While it boasts a sleek design, large touchscreen, and versatile connectivity options, it also has its fair share of challenges, such as the messy cords and difficult customer service. I'd recommend this product for businesses looking for a stylish and reliable POS system, but be prepared to face a few hurdles along the way. 🔗Casio PCR-T2300 Electronic Cash Registerhttps://preview.redd.it/1uu2h8zted1d1.jpg?width=720&format=pjpg&auto=webp&s=4abee1a70906134d15e54eff47fffca50d24061c I recently got my hands on the Casio PCR-T2300 Electronic Cash Register and let me tell you, it's been a game-changer for my business. With its 10-line LCD display, it's incredibly easy for me to check the current transaction and eliminate errors. The raised keyboard with 30 department key locations makes inputting data a breeze. Plus, with the built-in pop-up customer display, I can ensure my customers always know exactly what they're paying for. One of my favorite features of this cash register is the ability to customize receipts with a graphic logo or programmable top and bottom messages, adding a personal touch to each transaction. The heavy-duty metal cash drawer provides more than enough space for five bill compartments and five coin compartments, making it perfect for a busy retail environment. However, there are a few drawbacks that I've noticed during my time using this product. The instructions provided for programming the cash register could be more clear, leaving some users (like myself) scratching their heads at certain points. Additionally, while the register performs well overall, I have found that there can be some issues with the tape feeding, which can be frustrating at times. All in all, the Casio PCR-T2300 Electronic Cash Register has proven to be a reliable and efficient addition to my business operations. With its user-friendly design and robust feature set, it's definitely worth considering for any small retailer or grocer looking to streamline their cash-handling processes. 🔗Square Register Touchscreen Display, Grayhttps://preview.redd.it/p75qt1dued1d1.jpg?width=720&format=pjpg&auto=webp&s=d7961fd7f877439dcf756eb77fb73cfca5bb1bb2 I've been using Square Register - Touchscreen Display, Gray for quite a while now, and it's been a game-changer for managing my small grocery store. The system is incredibly intuitive, with a sleek touchscreen display that makes transactions a breeze. The customer display is perfect for keeping lines moving smoothly, and the compact design ensures my countertop stays clutter-free. One standout feature of the Square Register is its seamless integration with other Square services, like inventory management and customer feedback. This has made it incredibly easy for me to keep track of my stock and stay in touch with my regular customers. Additionally, the hardware is built to last, which is always a plus when you're investing in new equipment. However, there's one area where Square Register could improve – the lack of customization options. While the system works great out of the box, I sometimes wish I could tweak some settings to better suit my specific needs. Despite this minor flaw, the Square Register - Touchscreen Display, Gray has definitely helped streamline my operations and improve my customers' experience. 🔗Royal Alpha 583x Electric Cash Register for Small Businesshttps://preview.redd.it/ug2o5pxued1d1.jpg?width=720&format=pjpg&auto=webp&s=4491905c43edb7ebe407895a6d30640aba8bf9b6 I recently purchased the Royal Alpha 583cx Cash Register for my small business, and I couldn't be happier with my purchase. This little gem has made managing sales transactions a breeze. With 99 departments, 1000 PLUs, 26 clerks, and 4 tax rates, this cash register is fully equipped to handle the needs of any small business. One of the features that I absolutely love is the alpha numeric single station thermal printer. It not only prints fast but also allows me to customize the receipts with my company's message, making it a great marketing tool. Another great feature is the serial port for PC connection, which lets me use an optional bar code scanner, making the checkout process even smoother. However, one minor issue I experienced was with the paper feed. It tends to jam at times, but a quick fix usually solves the problem. Additionally, the display that shows the purchase amount could be more visible, especially in bright lighting conditions. Overall, I would highly recommend the Royal Alpha 583cx Cash Register to anyone running a small business. Its user-friendly interface, customizable receipts, and reliable performance make it a valuable asset to have in any retail or service environment.

The dual LCD displays provide clear visibility for both the clerk and the customer, making transactions seamless and efficient. One of the standout features is its capacity to handle up to 2,000 employees, which is more than adequate for a small to medium-sized business. Additionally, the unlimited messaging capability ensures that you won't miss any important announcements or updates. However, the product does feel a bit flimsy due to its predominantly plastic design, which might concern those who prefer a sturdier build. Another fantastic aspect of this cash register is the 999 Price Look-Ups, allowing for quick processing of transactions. Programming four different tax rates also makes the setup process incredibly straightforward. On the downside, the impact printer, although functional, occasionally feels outdated compared to more advanced models. Overall, the Royal 500DX Cash Register has proven to be a reliable and user-friendly addition to my small business.

The compact design allows it to fit easily in our small store, and the bright LED display makes it easy for us and our customers to see the transaction details. The 8 departments feature helps us organize our inventory, and the 80 PLU/Items capacity allows us to input all our products without issues. One of the standout features of this cash register is its ability to accept different payment methods like cash, cheque, and credit card, which has made it easy for us to cater to our customers' preferred payment options. Additionally, the time and date display feature ensures that our transactions are accurate and timely. However, there are a few minor drawbacks to the Sharp XE-A102. It can be a little noisy and slow compared to some other cash registers, which may be an issue during peak hours when we need to serve customers quickly. Moreover, the instructions provided are quite small, making them difficult to read and follow. Overall, the Sharp XE-A102 Electronic Cash Register has been an excellent addition to our start-up retail business. Its compact design, 58 mm wide reliable printing, and ability to accept multiple payment methods make it a valuable tool for any small retailer. While it may have a few minor issues, the majority of users, including myself, are satisfied with its performance and recommend it to others. 🔗Professional XE Series Electronic Cash Registerhttps://preview.redd.it/9ghz5oaedd1d1.jpg?width=720&format=pjpg&auto=webp&s=feaa1f9c3dd16f023352a745c133e2b9c5aab294 I recently added the Sharp XE Series Electronic Cash Register to my tiny boutique store, and I couldn't be happier. Before settling on this model, I spent a lot of time researching various cash registers, but the XE Series stood out for its advanced sales reporting capabilities and seamless tie-in with QuickBooks Pro. The moment I unboxed it, I was impressed by its sleek, professional appearance and built-in SC card slot for easy connectivity and data back-up. Setting up the register was incredibly easy, and within just a few hours, it was ready to go. Its intuitive interface made training my employees a breeze. The thermal printer was a pleasant surprise; it's much quieter and faster than traditional receipt printers. Plus, the customizable receipts with graphics and logos definitely give my store a professional edge. One of my favorite features is the automatic tax system, which not only saves time but also reduces the potential for errors and makes reporting so much easier. The locking drawer ensures security and comes with multiple bill and coin compartments, making deposits a lot more organized. The only downside is the rather complicated user manual, which could definitely be improved. It's not a complete deal breaker, though, as there are plenty of helpful YouTube tutorials available online. All in all, I'm thrilled with my purchase of the Sharp XE Series Electronic Cash Register. It's a perfect fit for my small business and a real game-changer when it comes to streamlining sales transactions and accounting. I wouldn't hesitate to recommend this cash register to anyone running a small retail or service business. 🔗Casio Single-Tape Thermal Cash Register for Businesshttps://preview.redd.it/9qo9ivmfdd1d1.jpg?width=720&format=pjpg&auto=webp&s=b796fc73fe9d4964333dedf01204832108f7316c Casio's PCR-T280 is a fantastic single-tape thermal cash register that offers more functionality for medium-sized businesses than entry-level models. With the ability to track up to 1,200 price lookups, it offers a level of specificity in item sales tracking not commonly found in its class. It also allows businesses to track sales up to eight different operators, making it an excellent tool for business tracking and growth. One of the standout features of this product is its hygienic, antibacterial keyboard. In our current world, where cleanliness is paramount, this characteristic provides a measure of peace of mind for both business owners and customers alike. Furthermore, its multipurpose tray can hold money in four bill compartments and five coin compartments, ensuring the efficient flow of transactions. The PCR-T280 also boasts a high-speed thermal printer, which can be used either for customer receipts or as a journal printer for recording all the store's activities. Its mode lock with key control feature provides multiple operation positions through physical keys, providing a level of security usually found in more expensive models. Although it is not touch-screen, its simple and intuitive design makes it easy to program and use. Some users did find the manual a bit difficult to follow, but with a bit of practice, most find it quite manageable. With its ability to handle multiple sales tax needs and its capacity for PLU capabilities, the Casio PCR-T280 has proven itself as a reliable tool for various businesses, small or medium-sized. However, one minor drawback is the depth of the money/change drawer, which could have been a little deeper for added convenience. Despite this minor issue, the vast majority of users recommend this register for its performance and price point, providing an excellent value for businesses looking for an affordable, reliable cash register solution. 🔗Heavy-Duty Cash Register with Alpha Keyboard and LCD Displayhttps://preview.redd.it/n49jkvmfdd1d1.jpg?width=720&format=pjpg&auto=webp&s=de539e0ebd57052b2847b9d3ccc982047c4b050e As an avid user of cash registers in my grocery store, I recently discovered the Royal Alpha 1100ml Cash Register, and my experience has been quite satisfactory. This heavy-duty register is perfect for my high-traffic establishment, offering a reliable and swift cash management system that I can always depend on. The first thing that caught my eye about this cash register was its single fast and quiet alphanumeric thermal printer, capable of handling over 1 million lines. It's been able to keep up with the constant rush of customers, making it a reliable addition to my store. The large 10-line LCD user display and alpha keyboard ensure easy programming, which was a breeze, even for a beginner like me. The SD Card slot is another excellent feature, enabling efficient accounting data transfers to a PC, a necessity for any modern business. However, I will say that the software included with the register can be a bit flaky at times. While it is supposed to read the x and z reports that the machine puts on the sd card, I sometimes find myself having to use the sd card to transfer report data manually. Additionally, getting in touch with their tech support doesn't seem to be very helpful, as they often provide no real technical assistance. Despite these minor issues, the Royal Alpha 1100ml Cash Register has been a solid addition to my store. Its heavy-duty locking cash drawer with four slot bill and removable five slot coin tray, along with its automatic tax computation, has made managing funds and keeping track of sales much easier for me. If you're in need of a reliable cash register for your business, I'd highly recommend giving this one a try. 🔗Fast and Accurate Cash Register System with Thermal Printing and 8-Line Displayhttps://preview.redd.it/f33rfq0gdd1d1.jpg?width=720&format=pjpg&auto=webp&s=e9314ab913ffe6b00f0a11467485ee790805c89a I recently discovered the Sharp XEA407 Cash Register while searching for a reliable and feature-rich solution for my little grocery store. After trying it out, I must say it's exceeded my expectations. The first thing that impresses anyone who lays their eyes on it is the sleek eight-line display. It's not just a pretty face though; it's got brains as well with 7000 Price Lookups (PLU's), allowing quick and accurate entry. The inclusion of 99 departments is brilliant as it makes managing diverse product types a breeze. My favorite feature? Hands down, the microban keytops. They provide built-in antimicrobial protection, keeping those pesky germs at bay, which is particularly important given the current health situation. And let's not forget about the large 32GB SD card slot for computer connectivity and data storage. However, there were a few hiccups too. The lack of French documentation was a letdown for me, a French-speaking Canadian. Plus, a few customers have reported missing parts upon delivery, making the product unusable. So, while there are some minor issues, the Sharp XEA407 Cash Register has overall been a reliable and efficient addition to my store. It's fast, easy to set up, and offers more than enough features for most small businesses. If you're looking for a cash register that combines modern tech with dependability, this might just be the one for you. 🔗Royal 100Cx Portable Battery/AC Powered Cash Registerhttps://preview.redd.it/ehbrx3qgdd1d1.jpg?width=720&format=pjpg&auto=webp&s=6336a0d1631936e4129065c3bb0ff8f80b083cff As a small business owner, I've been on the hunt for a reliable, portable cash register to make sales easier at my farmer's market stand. The Royal 100Cx, with its compact design and battery-powered operation, has been a reliable companion for me. The automatic tax computation feature is a game-changer, allowing me to easily manage sales and taxes on-the-go. However, the initial setup can be a bit daunting, and the manual doesn't do a fantastic job of explaining everything. The preset department pricing and sales analysis by category of merchandise are standout features that have helped me keep track of inventory and sales trends. It's crucial for businesses like mine, where inventory and sales fluctuate frequently. The ink roll printer provides a receipt printout, providing a professional touch to every transaction. In terms of drawbacks, one thing to note is that the tax computation is limited to only four rates – VAT, Canadian, and a couple of others – which may not cater to everyone's business needs. However, for my small farm market business, it's more than sufficient. Overall, the Royal 100Cx is a dependable piece of hardware, and it's been a significant asset in streamlining my sales process. It may have a slightly steep learning curve, but once mastered, it's a powerful tool for any small business seeking a portable, autonomous cash register solution. 🔗Royal 435dx Cash Register with 16 Department Capability and 8 Clerkshttps://preview.redd.it/p46ibzsgdd1d1.jpg?width=720&format=pjpg&auto=webp&s=388c3cad238c37035aa583f7a2fca3ca9b3546fb As a small business owner, I can attest to the convenience of the Royal 435dX Electronic Cash Register in my daily operations. Its 16 departments and 800 PLU's ensure an efficient flow of transactions, while the 8 clerk capacity and 4 tax rates enable seamless management, even for those serving in various locations or catering to international clientele. One of the highlights of this cash register is the front and rear LCD displays, allowing both the clerk and customer to see each transaction clearly. The memory protection with backup batteries provides added security to safeguard data in case of a power outage, a particularly valuable feature for businesses operating in areas with unpredictable power supply. However, a minor con would be the single station 57mm impact printer, which could limit the pace of transactions during peak rush hours. Also, the locking cash drawer tends to be a bit cumbersome, requiring more time than necessary to retrieve and return change. Despite these minor drawbacks, the Royal 435dX Electronic Cash Register has significantly improved my business operations, allowing me to keep track of transactions efficiently, even during peak hours. I would recommend this cash register to other small business owners looking for a reliable and feature-rich option that delivers exceptional performance at an affordable price point. 🔗Casio SE-S700 Cash Register: High-Speed Single-Station Thermal Printerhttps://preview.redd.it/bw8m582hdd1d1.jpg?width=720&format=pjpg&auto=webp&s=cda297dee8ba2852e9a6050cf6d8cd0952683543 I recently upgraded my old, heavy cash register to the Casio SE-S700, and I must say, it has made running daily transactions a breeze. The built-in rear customer display ensures that prices are accurate, while the 8 department keys and 999 PLUs make it a cinch to organize my inventory. One of my favorite features is the customizable receipt header, allowing me to print unique messages on each customer receipt. The large, easy-to-read LCD display ensures that no mistakes are made during sales transactions. However, there are a few cons to consider. The plastic construction doesn't instill much confidence in its durability, and I wish the cash register drawer featured a more secure locking mechanism. Overall, the Casio SE-S700 has proven to be a reliable and efficient cash register for my small business, saving me time and preventing any hassles when it comes to handling transactions. 🔗Refurbished Sharp XE-A106 Sleek Microban Cash Registerhttps://preview.redd.it/pv6bngihdd1d1.jpg?width=720&format=pjpg&auto=webp&s=5531ba303d34110e9ab375d0da811cd88813ade8 I recently got my hands on the Sharp XE-A106 Cash Register and boy, am I impressed! This refurbished gem has been a game-changer in managing sales at my small business. The first thing that caught my eye was the Microban antimicrobial keys. It's not just about style; it's about hygiene too! The large LED screen is another feature that I absolutely adore. With one line for eight digits, it's so easy to keep track of prices and sales. The drum printing on standard 2-1/4" plain paper roll is fast and quiet, making it perfect for my retail store. Plus, with functions like eight preprogrammed departments, 80 price lookups, four clerk numbers, auto-tax system, and flash reporting, managing sales has never been easier. But wait, there's more! The locking cash drawer with four-slot bill compartments, five-slot removable coin tray, and a media slot for quick deposit of checks and bills is just brilliant. Not to forget the easy programming that took me under an hour to set up. However, nothing's perfect. The one downside I noticed was the slow printing speed. Also, you can't turn off the receipt printer for a "no sale" option. All in all, the Sharp XE-A106 Cash Register is a reliable workhorse for any small business. Despite the few drawbacks, it's worth every penny. If you're in the market for a cash register, this should definitely be on your list! 🔗Royal 6000ML Compact Cash Register with 10 FT Cord, 6000 Price Look-ups, and 36 Departmentshttps://preview.redd.it/z2g8nyuhdd1d1.jpg?width=720&format=pjpg&auto=webp&s=81c258294f362b2178c26fb0205217b7bdf1d328 I recently purchased the Royal 6000ML Cash Register for my small grocery store, and I have to say, it's been a game-changer. This compact cash register has truly helped streamline our operations, making it easier than ever to manage sales and generate accurate reports. One of my favorite features is the 36 Department categorization, which has allowed me to analyze sales data in a more detailed manner. Additionally, the 6,000 Price Look-ups (PLUs) have made entering frequently sold items quick and easy. The alphanumeric thermal printer, along with the front display and rear LED display, ensures that I can keep track of transactions with ease. However, there have been some cons as well. The initial setup was a bit challenging due to the lack of clarity in the instruction manual. Some users have also reported issues with the power cord connecting properly to the register. Overall, despite a few hiccups during setup, the Royal 6000ML Cash Register has been a valuable addition to my business. Its efficiency and ease of use make it an ideal choice for small-scale retail operations.

2024.05.19 11:23 Accurate-Screen8774 A Decentralized Microfrontend Architecture
Disclaimer: the following is a recent medium article. it is being posted in full on Reddit to compare feedback and engagement of Reddit users with long-form articles.Decentralization can mean a lot of things because it can be open to interpretation. In this article, we would like to talk about what decentralization means to us and how we are approaching our definition of decentralized. We are working on a typical chat app, but our approach is unique and may push the boundaries of what it means for something to be self-hosted. Our decentralized chat application is built as a Progressive Web Apps (PWA) and leverages modern web technologies to deliver a user experience comparable to native apps. Unlike traditional centralized chat apps, our chat app is designed to operate independently of central servers, ensuring that user data remains private and secure. This article will delve into the various components and architectural decisions that make our app truly decentralized. The Decentralized Chat AppAn overview of how our chat application leverages Progressive Web App (PWA) technology to provide a seamless user experience across different devices and platforms.https://preview.redd.it/ntyghqt5oc1d1.png?width=1100&format=png&auto=webp&s=f273717c0c26ef5befcd303fc45de104af63f8d0 Data Storage and NetworkingA typical app relies heavily on data storage and networking capabilities. In our decentralized chat application, we’ve implemented advanced solutions to handle these aspects efficiently and securely.Data StorageIn our app, we use IndexedDB to store data directly in the browser’s storage. While browsers provide multiple options for storing information, ranging from cookies to local storage, IndexedDB offers a more advanced and robust solution.Capacity: IndexedDB can store significantly larger amounts of data compared to cookies or local storage. Structure: It allows for complex data structures, including collections of files and blobs. Performance: IndexedDB operates asynchronously, meaning it won’t block the main thread of your application, leading to better performance for data-heavy applications. Using IndexedDB, we ensure that user data is stored locally on their devices, providing both privacy and independence from central servers. NetworkingFor networking, our app uses PeerJS-server as a connection broker to establish WebRTC connections between peers.Direct Peer-to-Peer: WebRTC, provided by the browser, enables real-time communication between peers. This allows two users to connect directly and exchange data with minimal latency. Efficient Routing: Once a connection is established, data is sent via the shortest possible network route, enhancing speed and efficiency. Multiple Connections: Browsers can handle multiple WebRTC connections simultaneously, though the number of connections can vary depending on the device and network capabilities. PeerJS-server helps in the initial connection setup by acting as a signaling server. It facilitates the exchange of connection information between peers, enabling them to establish a direct WebRTC connection. By leveraging IndexedDB for data storage and WebRTC with PeerJS-server for networking, our chat application achieves a high level of decentralization, ensuring user data remains private and connections are efficient and reliable. These components form the backbone of our approach, pushing the boundaries of what it means for an app to be truly self-hosted and decentralized https://preview.redd.it/ww704u7foc1d1.png?width=1100&format=png&auto=webp&s=0c4d4958a38747a4b0410c4c8526e0fd941fac35 Static Distribution and DeploymentOur app is essentially a bundle of static files, which makes it highly portable and easy to distribute. We leverage AWS services such as S3 and CloudFormation to deploy our app, ensuring it is distributed efficiently over a Content Delivery Network (CDN) across AWS servers.AWS S3 and CloudFormationAWS S3: We host our app on AWS S3, a scalable storage service that allows us to serve static files reliably. S3 ensures that our app is always available and can handle large numbers of requests without performance degradation. CloudFormation: By using AWS CloudFormation, we automate the deployment process, managing our infrastructure as code. This makes it easy to replicate and manage our app’s deployment environment.Hosting on S3 and using CloudFormation means our app benefits from AWS’s global CDN. This ensures that our static files are cached and served from servers closest to our users, reducing latency and improving load times. Offline Availability and Self-HostingWe go a step further by providing users with the option to download a zip file of the app directly from within the app. This ensures that users can run the app locally without relying on our servers.Direct from Index.html: Unlike some other apps, our app is a pure JavaScript implementation, designed to run directly from the index.html file. Users can simply open this file in their browser and start using the app without needing a server. Docker Option: For users who prefer or require a server setup, we offer a Docker configuration. This allows the app to be run in a containerized environment, providing flexibility and ease of deployment for different use cases. Unminified Code for TransparencyWe believe in transparency and accessibility. Therefore, we run the app as unminified code. This has several advantages:Ease of Download: Users can download the entire app using simple browser commands like Ctrl/Cmd+S. Transparency: By providing unminified code, we ensure that users can inspect and understand the code they are running. This fosters trust and allows for easier customization and debugging. By distributing our app as static files and offering multiple ways to run it, we ensure that users have maximum flexibility and control. Whether using AWS’s robust infrastructure or running the app locally, our approach embodies the principles of decentralization and user empowerment. Webpack 5 Module FederationOur app leverages Webpack 5’s Module Federation feature to implement a microfrontend architecture. This approach allows us to modularize our application, making it easier to maintain, develop, and scale. You can explore our open-source implementation here: https://github.com/positive-intentions/frontend-base.Current ImplementationWe have used Webpack 5 Module Federation to build the chat application, which you can find here: https://github.com/positive-intentions/chat. Additionally, we have created a federated module for cryptography that can be imported at runtime, available here: https://github.com/positive-intentions/cryptography. Our current setup is straightforward, allowing us to dynamically load different parts of the application as needed. This modular approach provides flexibility and efficiency in how we develop and deploy our app.Future EnhancementsWe plan to further decompose the application into separate microfrontends, each responsible for a specific aspect of the app. This will not only simplify maintenance but also enhance documentation and development processes for individual components.Planned Modules: 1. UI Components: A collection of reusable UI components that can be shared across different parts of the application, promoting consistency and reducing duplication. 2. P2P Framework: The core framework for peer-to-peer networking, facilitating real-time communication between users. 3. State Management: This module will manage the application’s state, ensuring efficient data handling and synchronization across different components and peers. 4. Permission Manager: A dedicated module for managing user permissions and access control, enhancing security and user management. https://preview.redd.it/w16teobjoc1d1.png?width=1100&format=png&auto=webp&s=9305db7dc16981aaf8499bfa2a7aade3c44a06d2 Individual Storybooks and Module ExportsEach module will have its own Storybook and module export, providing a dedicated space for documentation, testing, and showcasing individual components. This approach will:Enhance Documentation: Each module will be well-documented, making it easier for developers to understand and use them. Simplify Maintenance: By isolating modules, we can update and maintain them independently, reducing the risk of breaking changes affecting the entire app. Promote Reusability: Well-defined modules can be reused across different projects, promoting a modular and efficient development approach. By embracing Webpack 5 Module Federation and breaking down our app into distinct microfrontends, we aim to create a more robust, scalable, and maintainable architecture. This approach not only benefits our development process but also enhances the overall user experience by ensuring that each component is well-crafted and easily accessible. Redundancy and ReliabilityIn the past, we have encountered difficulties when deploying our app to AWS due to various technical issues. Given that our app functions as a self-hosted static application, we have started exploring alternative hosting options, such as GitHub Pages. You can view our deployment on GitHub Pages here: https://positive-intentions.github.io/chat.GitHub Pages DeploymentOur microfrontend architecture allows us to deploy each module independently. This capability has enabled us to host copies of the app on GitHub Pages for each repository. While this approach is unconventional and can lead to redundant copies of the app, we believe it is a valuable exercise in exploring module federation redundancy.Accessibility: Hosting on GitHub Pages makes the app easily accessible to users and developers. Simplicity: GitHub Pages offers a straightforward deployment process, reducing the complexity often associated with other hosting solutions. Cost-Effective: GitHub Pages is free, making it an economical choice for hosting static sites. Redundancy and InteroperabilityWe aim to make our app interoperable across different hosting sources. By leveraging Webpack 5 Module Federation, we can ensure that the app works seamlessly whether it is served from AWS or GitHub Pages. This redundancy enhances the app’s reliability and availability.Module Federation Redundancy: We are investigating ways to make modules interoperable between different sources, ensuring that the app remains functional even if one source becomes unavailable. Interoperable Deployment: Our goal is to allow the app to fetch and integrate modules from both AWS and GitHub Pages dynamically. https://preview.redd.it/m1nbx4nloc1d1.png?width=1100&format=png&auto=webp&s=b7e708e530bece6bcbd492b2699755065b783eb0 Future PlansTo further enhance our deployment strategy, we plan to use a infrastructure as code tool, to deploy the app across multiple cloud service providers. This approach will increase the resilience of our deployment, ensuring the app remains online and functional even if one provider experiences downtime.Multi-Cloud Deployment: We can deploy the app to various cloud service providers, including AWS, Azure, and Google Cloud. This will distribute the app’s load and reduce the risk of a single point of failure. Scalability: This will enable us to scale the app easily across different providers, ensuring it can handle increased traffic without performance issues. Cost Management: Static file hosting is relatively a cheap option for hosting a webapp, we can optimize costs and ensure that the app remains affordable to maintain. By exploring these new hosting options and implementing a robust deployment strategy, we aim to make our decentralized chat app more resilient, scalable, and cost-effective. Our efforts in redundancy and interoperability will ensure that the app continues to function seamlessly, providing a reliable user experience regardless of the hosting source. Multi-Device ArchitectureAs our app continues to develop, we are excited to introduce the concept of a decentralized profile that can be shared across multiple devices. This feature is designed for individuals who want to use the same profile on all their devices, providing a seamless and integrated multi-platform chat experience, much like any modern chat application.Decentralized ProfileA decentralized profile allows users to maintain a consistent identity and settings across different devices. This means that whether you are using a smartphone, tablet, or desktop, your profile can remain synchronized and up-to-date.Profile Synchronization: Users can access their chat history, contacts, and settings on any device by synchronizing their decentralized profile. Data Consistency: Changes made on one device are automatically reflected on others, ensuring a consistent experience. Multi-Platform Chat ExperienceImplementing a decentralized profile enables us to offer a robust multi-platform chat experience. Users can switch between devices without losing their chat continuity or settings, enhancing the overall user experience.Convenience: Users can start a conversation on one device and continue it on another without any interruptions.

https://preview.redd.it/wqrh8ahk5c1d1.png?width=824&format=png&auto=webp&s=5eee98a84c0072df8c688597c1b1acbbd113a104 submitted by CloudysYe to ChaosEngineering [link] [comments] Recently, I have been doing chaos (fault) tests on the robustness of some self-built database driveclient base libraries to verify and understand the fault handling mechanism and recovery time of the business. It mainly involves the two basic components MongoDB and etcd. This article will introduce the relevant test methods. Fault test in MongoDBMongoDB is a popular document database in the world, supporting ACID transactions, distributed and other features.Most of the articles on chaos (fault) testing of MongoDB in the community are simulated by processing monogd or mongos. For example, if you want MongoDB to trigger copy set switching, you can use a shell script like this: # suspended the primary node kill -s STOPThe above-mentioned means are generally system-level, if we just want to simulate a MongoDB command command encountered network problems, how to do further want to conduct more fine-grained testing. In fact, MongoDB in 4.x version above has implemented a set of controllable fault point simulation mechanism -> failCommand. When deploying a MongoDB replica set in a test environment, you can generally enable this feature in the following ways: mongod --setParameter enableTestCommands=1Then we can open the fault point for a specific command through the mongo shell, for example, for a find operation to make it return error code 2: db.adminCommand({ configureFailPoint: "failCommand", mode: { "times": 1, }, data: {errorCode: 2, failCommands: ["find"]} });These fault point simulations are controllable, and the cost is relatively low compared to the direct destruction on the machine, and it is also suitable for integrating into continuous integration automation processes. The MongoDB built-in fault point mechanism also supports many features, such as allowing a certain fault probability to occur, returning any MongoDB supported error code type, etc. Through this mechanism, we can easily verify the reliability of our own implementation of the MongoDB Client Driver in unit tests and integration tests. If you want to know which fault points the MongoDB supports, you can check the specification provided by the MongoDB in detail, which mentions which fault points the driver can use for testing for each feature of the MongoDB. MongoDB, there are many examples in the dirver code repository of the official go implementation that can be: https://github.com/mongodb/mongo-go-driveblob/345ea9574e28732ca4f9d7d3bb9c103c897a65b8/mongo/with\_transactions\_test.go#L122. Fault test in etcdetcd is an open source and highly available distributed key-value storage system, which is mainly used for shared configuration and service discovery.We mentioned earlier that MongoDB has a built-in controllable fault point injection mechanism to facilitate us to do fault point testing, so does etcd also provide it? Yes, etcd officials also provide a built-in controllable fault injection method to facilitate us to do fault simulation tests around etcd. However, the official binary distribution available for deployment does not use the fault injection feature by default, which is different from the switch provided by MongoDB. etcd requires us to manually compile the binary containing the fault injection feature from the source code for deployment. etcd has officially implemented a Go package gofail to do "controllable" fault point testing, which can control the probability and number of specific faults. gofail can be used in any Go implementation program. In principle, comments are used in the source code to bury some fault injection points in places where problems may occur through comments (// gofail:), which is biased towards testing and verification, for example: if t.backend.hooks != nil { // gofail: var commitBeforePreCommitHook struct{} t.backend.hooks.OnPreCommitUnsafe(t) // gofail: var commitAfterPreCommitHook struct{} }Before using go build to build the binary, use the command line tool gofail enable provided by gofail to cancel the comments of these fault injection related codes and generate the code related to the fault point, so that the compiled binary can be used for fine-grained testing of fault scenarios. Use gofail disable to remove the generated fault point related codes, the binary compiled with go build can be used in the production environment. When executing final binary, you can wake up the fault point through the environment variable GOFAIL_FAILPOINTS. if your binary program is a service that never stops, you can start an HTTP endpoint to wake up the buried fault point to the external test tool by GOFAIL_HTTP the environment variable at the same time as the program starts. The specific principle implementation can be seen in the design document of gofail-> design. It is worth mentioning that pingcap have rebuilt a wheel based on gofail and made many optimizations: failpoint related code should not have any additional overhead; Can not affect the normal function logic, can not have any intrusion on the function code; failpoint code must be easy to read, easy to write and can introduce compiler detection; In the generated code, the line number of the functional logic code cannot be changed (easy to debug);Next, let's look at how to enable these fault burial points in etcd. Compile etcd for fault testingcorresponding commands have been built into the Makefile of the official etcd github repository to help us quickly compile the binary etcd server containing fault points. the compilation steps are roughly as follows:git clone git@github.com:etcd-io/etcd.git cd etcd # generate failpoint relative code make gofail-enable # compile etcd bin file make build # Restore code make gofail-disableAfter the above steps, the compiled binary files can be directly seen in the bin directory. Let's start etcd to have a look: # enable http endpoint to control the failpoint GOFAIL_HTTP="127.0.0.1:22381" ./bin/etcdUse curl to see which failure points can be used: curl afterCommit= afterStartDBTxn= afterWritebackBuf= applyBeforeOpenSnapshot= beforeApplyOneConfChange= beforeApplyOneEntryNormal= beforeCommit= beforeLookupWhenForwardLeaseTimeToLive= beforeLookupWhenLeaseTimeToLive= beforeSendWatchResponse= beforeStartDBTxn= beforeWritebackBuf= commitAfterPreCommitHook= commitBeforePreCommitHook= compactAfterCommitBatch= compactAfterCommitScheduledCompact= compactAfterSetFinishedCompact= compactBeforeCommitBatch= compactBeforeCommitScheduledCompact= compactBeforeSetFinishedCompact= defragBeforeCopy= defragBeforeRename= raftAfterApplySnap= raftAfterSave= raftAfterSaveSnap= raftAfterWALRelease= raftBeforeAdvance= raftBeforeApplySnap= raftBeforeFollowerSend= raftBeforeLeaderSend= raftBeforeSave= raftBeforeSaveSnap= walAfterSync= walBeforeSync=http://127.0.0.1:22381Knowing these fault points, you can set the fault type for the specified fault, as follows: # In beforeLookupWhenForwardLeaseTimeToLive failoint sleep 10 seconds curl -XPUT -d'sleep(10000)' # peek failpoint status curl sleep(1000)http://127.0.0.1:22381/beforeLookupWhenForwardLeaseTimeToLivehttp://127.0.0.1:22381/beforeLookupWhenForwardLeaseTimeToLive For the description syntax of the failure point, see: https://github.com/etcd-io/gofail/blob/mastedoc/design.md#syntaxso far, we have been able to do some fault simulation tests by using the fault points built in etcd. how to use these fault points can refer to the official integration test implementation of etcd-> etcd Robustness Testing. you can search for relevant codes by the name of the fault point. In addition to the above-mentioned built-in failure points of etcd, the official warehouse of etcd also provides a system-level integration test example-> etcd local-tester, which simulates the node downtime test in etcd cluster mode. Well, the sharing of this article is over for the time being ღ( ´・ᴗ・` )~ Commercial break: I recently maintenance can maintain multiple etcd server, etcdctl etcductl version of the tools vfox-etcd), You can also use it to install multiple versions of etcd containing failpoint on the machine for chaos (failure simulation) tests! |
