Navigating the Complexities of English Strategies for Success
English, renowned for its versatility and richness, presents a labyrinth of challenges for both native and non-native speakers alike. The intricacies of its structure, encompassing homophones, heteronyms, irregular spellings, idioms, and regional variations, often leave learners bewildered.

2023.05.28 22:05 Dyl8Reddit I’ve been collecting the Bing Word of the Day for an entire year now!

On the day that I posted this, 5-28-2023, it would have been an entire year since I started collecting the daily word that Bing offers every day. For those of you don’t know, if you search for “Word of the day” on Bing, you will find a unique vocabulary word that is specific to each day. That’s what I’ve been documenting for the past year.
I started collecting the words back on May 29, 2022. I kept them in a plain text document that I named word-of-the-day.txt. This document was going to store my words in a specific format, which you will see below. I appended to this document every day in the summer using Windows Notepad, until I eventually moved the document to my Google Drive. This allowed me to hook up multiple automations to it, like a Siri Shortcut that would get the latest word and allow me to append it. Once April of 2023 (or even earlier) came around, I decided to change to only updating it every 6 days since my life was getting a bit busier then. And when I wasn’t automating, I would manually add the daily word as part of my MicrosoftRewards routine (sometimes, but only when I had the extra time for it)
Doing this isn’t as easy as going back to add all 365 words right before I published this. That is because there is a limit to how far back one can go in the daily words — after 7 days a word disappears from the end of the list and is lost forever. This meant that I had to stay on top of the word list, which I did do pretty consistently until I missed on day on June 30th. But that’s ok, as we all make mistakes.
While I was keeping track of the words that Bing offered every day, I learned some interesting things. Discovering a new word every day slowly strengthened my vocabulary to be more eclectic. I used these words in various things like stories, or just to confuse people that had never heard of the words. And with more words, what started as a hobby to collect the words became a project to archive the WOTD for an entire year.
A lot can happen in a single year. When I started, I didn't even have a Reddit account, and it was late May around the time where everyone gets out of school that I started making the list. Now it’s the end of another school year. I am completely different person.
So with that context and reflection, I would say that it is about time to show you the list that I’ve been collecting:*

2021.12.14 15:49 TheOneNeartheTop Use Google to Your Advantage and Expand Your Niche by Targeting Semantic Fuzz

Imagine this scenario:
You've started ranking well within your niche, but you're running out of topics.
What should you do next? How far should you niche down? Is this niche done?
The answer, as always is - It depends. First, you need to decide whether it's worthwhile to continue working on your niche site, or if you should start putting your energy into another site/topic.
What I'd like to discuss today is something I've been working on that's allowed me to grow a niche that I had thought was finished.
I call it Semantic Fuzz

Expanding your niche by targeting Semantic Fuzz.

This bolt from the blue came about on one of my YMYL websites which had gained great authority but was tapped out. It has links from Forbes, NYT, Vice, Washington Post, and more, but according to the name that I had stuck it with, it was done. I was number one in my niche, but there was nowhere else to go.
For this Case Study, we'll say my YMYL site is in the Financial Sector (it's not), and it's called Algo Stocks. I've niched down as far as I could and am currently the premier source of information about Algorithm Investing & Bot Trading.

What is Semantic Fuzz?

It's an SEO term for similarly spelled words with different meanings. These are homographs, homonyms, and even words with the same prefix.
Did I just make that term up right now? Yes. But at least I'll rank for it.
Although you will see benefits on Prefixes or Homographs that aren't related to your niche you will still have more success with posts that are more closely related to your niche. Here's a few separate examples of Semantic Fuzz using keywords you might find on the aforementioned example site Algo Stocks:
Stock(The investment vehicle) – Stockpile, Stocked (Resupply), Stocking (For your feet), Stocky, Stockade
Futures (The investment vehicle) – Future (Time)
Trading – Traditional, Tradesman, Trades
Crude (Oil) – Crude (Raw)
Closing Market – Closed (action)
Opening Market – Open (action)
Market (Stock Market) – Action word for affiliate reviews 'Are you in the market for?'
Dow (Jones) – Dowry (Wedding) – This one is a bit of a stretch, and would require you to move way outside your niche, although it does illustrate my point.

How far should you push this?

Really it depends on what you want to try; ideally you should be putting your users first. If you have a lot of subscribers, it would be best not to push unrelated content out to them, but if you're a pure SEO play, there's no harm in burying some content deep in your website to test it out.
The best part of this thought exercise is going through your backlinks/current content with an open mind to expand your niche and create new content.

Now on to the Data

My main backlinks to my YMYL site often involve a word ending with 'ING', so I created some content that has the same prefix, but different meaning. An example of this would be having backlinks for 'sampling' as it relates to music production and then using that link juice to rank for the term 'samples' as it relates to tester size items (food samples, perfume samples, trials, etc).

Semantic Fuzz H1 Keyword Difficulty Traffic 3 Months Traffic 6 Months Traffic 1 Year
Exact Match Easy 67 539 N/A
Semantic Fuzz Medium 53 894 3576
None (Within my niche) Easy 15 49 89
Exact match means that the term exactly matches my backlink profile both in meaning and spelling.
Fuzzy is a fuzzy semantic match (think music sampling vs free samples)
None broader niche - This is an article that is within my broader category but doesn't use any keywords that I have authority for (Think sampling music to orchestra)
One thing that should be noted is that in my example the Fuzzy match (sampling to samples) goes to an entirely unrelated YMYL niche. Think Financial to Medical. While the ones labelled None Broader Niche are decent articles that are written in the same (financial) niche but on unrelated topics that I have not ranked for.
I have some more articles in the pipeline to test out this theory more, but for this exact term, the data might not be as clear since I'm now ranking for this term with some backlinks coming in as well.
YMMV and remember your User Experience should come first.
It should also be noted that if Google becomes more adept at identifying this in the future, it won't matter because you'll have gained authority and will be ranking naturally for these terms.

CRYPTOCURRENCY SCAMS EXPLAINED BY TYCOON.IO

https://preview.redd.it/e1xr1g81c5z61.png?width=1024&format=png&auto=webp&s=9453925b81125520c7862d0ec217e982980f726a
During the bull market, the scammers come out of hiding. In this article we will arm the crypto investor with the needed knowledge to avoid them.

Since all the transactions on the blockchain are irreversible, in 90% of the time people lose their coins due to ignorance and negligence. In the other 10% of the times there are swarms of well organised scammers who help to separate the new investors from their money. Scams have been around since the dawn of time. From phishing and sim-swapping to MLM groups, these modern scams are as diverse as they are creative. Let’s get prepared as crypto-investors to counter all of these attempts on the sanctity of your coins.

Bitconnect and other ponzi schemes.

https://preview.redd.it/kwwlcrw4c5z61.png?width=1024&format=png&auto=webp&s=a1de821820a5e5199c5bb328725e0c20cad5b674
In classic finance, the infamous Charles Ponzi has solidified his place in history as being the most famous user of the pyramid scheme carrying his name. Off course since then he has been outdone by Bernie Madoff. The idea behind the ponzi scheme is very simple. The owner of the pyramid structure pays out certain financial gains to the current investors using the money that was gathered from new investors that join this scheme. It’s a classic example of borrowing from Peter to pay Paul and this scam is as old as time.
Usually ponzi schemes are very common in classic finance and can sometimes run for years while duping even the most sophisticated investors. For example Bernie Madoff’s ponzi fund actually used a waiting list for new clients, as well as an intricate web of fake accountancy to cover his tracks. This way even the large institutions fell prey to his charm.
In crypto space there are many ponzi schemes and there will be many more as we move along. Mostly they play on human greed and psychology, promising irresistible ( and oftentimes impossible ) gains. Therefore the thick dense cloud of pure bullshit usually ends up canceling any logic. The crypto space is inherently risky, therefore whenever someone is waving a flag of “guarantee” in front of your eyes, it’s usually a trap. Also keep in mind that ponzi schemes feed on the continuous flood of new money from new unsuspecting victims. If you HAVE TO refer people into a certain “investment”, or if the whole point of this investment is to lure new people into it ( because you will then get into a higher tier inside the system, while you build your “downline” ), be advised you have a ponzi infestation on your hands. Let’s examine out the most famous examples.
The iconic face of Carlos Matos yelling “Wassa wassa wassup!” has become a globally recognisable meme since 2017. Bitconnect ( and Onecoin ) are great examples of a pure ponzi scheme in action. Not only did these so-called “Lending platforms” promised their investors outrageous returns ( oftentimes of 40% monthly income ), but they also used an army of advertisers and youtube influencers to promote their operation. Influencers such as Trevon James and Crypto Nick have become so infamous, that nowadays people even use their faces to create non fungible tokens. Ironically they are selling like hot cakes.
Another great example of ponzi schemes are the so called “cloud mining” and “bot trading” platforms. The story goes like this; invest with us, because we use your money to invest in cryptocurrency mining hardware and trading bots that generate a guaranteed ( that word again! ) income on a monthly basis. Oh yeah and if you sign up your brother, sister, friend, mom, dad, aunt Becky and your dog, you will rise in the levels and will receive even more guaranteed monthly income! What’s not to like right?
For starters any cryptocurrency miner ( and trader ) can tell you that if they are successful in their operation, they will never need outside funding from anyone, let alone a swarm of new investors to feed their machine. Aside from creating a bureaucratic nightmare ( who wants to manage an army of customer service reps? ) it also distracts them from the primary goal of mining and trading. When we analyse the Tycoon platform, we will see that it actually started out as a tool for internal use. Only upon the realization that this tool didn’t yet exist in the crypto space, the long 3 year work has begun in order to build and develop the project ( using own private capital ).
As long as there is human greed, there will be ponzi schemes. Always remember that if the project is forcing their clients to bring in new people into the machine and guarantees steady monthly income, it’s usually a trap. Sadly the people who participate in ponzi schemes are so brainwashed, that it’s impossible to reason with them when you present them with the truth. Only way to crack them is by examining their knowledge of cryptocurrency fundamentals. Trevon James and Crypto Nick never even knew what a private key is, therefore knowledge of your power. Educate yourself and study historic examples. They do tend to repeat.

Giveaway scams

https://preview.redd.it/qsrsgya8c5z61.png?width=1024&format=png&auto=webp&s=39157fd513d6ece0142db14202293cc37789fd50
Did you ever wonder why Barack Obama or Elon Musk suddenly became overjoyed by philanthropy and started to just give away free Bitcoin and Ethereum to anyone who sends them a tiny amount of coins? The answer is; They off course don’t do it! This is how a crypto giveaway scam usually works. Some famous person tweets out a message saying that he’s going to multiply any Bitcoin you send him. Of course you have to FIRST send them a tiny amount of coins. By now you off course know that all transactions that are done on-chain are irreversible, so gullible people time and time again end up waving goodbye to their coins by sending off aboard a digital Titanic.
While giveaway scams have become less of a “hot” thing as they used to be, there are still people who actually fall for them. The key here is that the message has to originate from a credible source. Scammers even went to great lengths ( such as hacking social media accounts of famous people ) to be perceived as legitimate. Nowadays big social media networks try to crack down on these scams, but time and time again they do pop up.
Just remember that in the cryptocurrency space there is no such thing as a free lunch. Yes there are legitimate airdrops and crypto faucets around, but these projects exist in order to reward early users for their effort. The users on their part must do the grunt work of self study and utilisation of the platform in order to receive the reward ( that is often never mentioned and ends up arriving as a nice unexpected surprise ). Most famous cases of this are off course the Uniswap and 1INCH token airdrops. But even these platforms never claimed that they would “multiply” the coins that are sent to them. They are decentralised exchanges that provide a valuable service. Love comes from both sides in this equation and reciprocity is mutual. Anyone claiming that they can simply multiply the coins you send them are off course scammers.

Phishing scams and their variants

https://preview.redd.it/eax2783bc5z61.png?width=1024&format=png&auto=webp&s=f157209025986d27c3174c5956b8257a99dd7f7e
Knowledge is power and in the cryptocurrency space that knowledge is so valuable that not only will it help you to find that next 10 to 50x gem, it will also help you to avoid phishing scams. This is why a lazy investor is the favourite prey of this infamously effective scheme. The purpose of the phishing scam is to obtain sensitive information from the cryptocurrency investor in order to plunder his/her wallets or accounts. Phishing scams originate from the classic finance where anything that is secured or password protected can ( and has been ) cracked successfully.
Imagine you receive an email from Binance claiming that you just won a 50 000 usd prize. All you have to do is log in and claim it. This is where overjoyed new crypto investors often fall victim to attacks. They usually fail to notice that the email address looks a bit “odd” ( because the letters actually contain what’s called homograph characters and not real legitimate letters ) The user then logs into a fake version of Binance and happily surrenders all of his/her personal information. Again logic is the key here. Never just trust a random email and always verify the email address that sent it. Also bookmark your important pages, because phishing attackers oftentimes advertise their domains in order to become visible on the first page of Google. Last but not least use your 2FA verification religiously and as often as possible.
Another popular phishing attack that has stirred up trouble is called a “Private key” attack. The space of decentralised finance is becoming hot and bustling with a flood of daily newcomers, therefore many new crypto users ( who don’t know that you absolutely must never show your private key to anyone ) fall for this attack. People can either download a malicious wallet or be led to a malicious website ( copying My Ether Wallet for example ) where they will be asked to enter their private key. Once this is done, the attacker can off course drain the REAL wallet in the process. One unlucky user lost 1400 Bitcoin in a similar attack. Therefore it’s important to always be sure you are downloading the official software and never use google ads on the top of your search results. Technical users can certainly use a digital signature of the official software that they have just downloaded. Remember knowledge is power.
The last ( but definitely not final ) variant of a phishing scam is currently rampant on social media platforms. This scam involves impersonation of a group admin ( usually on Telegram ). An official looking impersonator would copy all the details from the support admin including a picture and will start to contact newcomers. This way people can be fooled into giving away their sensitive information in order for the attacker to access the official account or wallet. This is why most admins on Telegram actually state in their name that they will “Never DM you first”: meaning that they never will contact anyone directly. It is often the impatient crypto investors who fall prey to this attack. Therefore it’s important to use only the official email provided by the support staff of the crypto project that you are following on social media. Again it’s always important to realize that there is no such thing as a free lunch and as we move through this bustling bull market, more and more phishing scams will come to light.

Fake wallets and Sim swapping

https://preview.redd.it/hwjo550ec5z61.png?width=1024&format=png&auto=webp&s=f310308f31bfc6ea59c715fe56b28be3a229aba6
A while back Ledger ( one of the most popular cold storage wallets on the market ) has suffered an attack on the database containing the contact information of their clients. Naturally that information has already fetched a pretty penny after being sold on the darknet markets. This is why it’s important to know about the “spear phishing” attacks.
When a user of a cryptocurrency wallet receives an unsuspecting email prompting them to download the “latest version” of their wallet in order to update it, rest assured that this is a spear phishing attempt on your funds. You see any respectable hot or cold storage wallet ALWAYS pushes the updates internally via the wallet application itself. Never from the outside world and definitely not via email. These attacks have claimed many victims and will continue to wreak havoc upon the unsuspecting newcomer to crypto space.
Just when you thought you might secure your wallet account with a text message authentication, think again! There are hordes of social manipulation masters who specialise into conning phone company employees into reprogramming a phone’s sim card onto a new malicious one that’s being controlled by the attacker. The phone numbers can originate from hacked data stolen from databases like the Ledger. This is why 2FA authentication must only be used via google’s authentication app or similar software.
Again this leads us to the matter of exercising caution whenever you browse through your emails, text messages and hell, even comments from social media posts. Many of these are smeared with honey luring potential victims into the scammer’s traps. The further we move ahead developing the current trends like DEFI and NFT’s, the more we will have to deal with scams. One of the most notorious, is off course the Rug pull. Let’s take a closer look.

Flying carpet – The Rug Pull

https://preview.redd.it/mi41ztzhc5z61.png?width=1024&format=png&auto=webp&s=8ebce1e5223760cba1ed732cc8efb2a4478c334c

Aside from the incredibly restrictive global lockdowns, the summer of 2020 has given us the rise of DEFI ( decentralised finance ) and off course Yield farming. This is why the Rug-pulling scam can be compared to the fraudulent ICO’s of the 2017. The idea here is very simple.
People are enticed to provide liquidity for a decentralised finance project with an intentionally malicious code baked into it. Usually people lock up liquidity ( their coins ) in order to “farm” rewards that are paid out to the participants in return for their help in the process called market making. All nice and dandy, but when the project is fraudulent, things tend to take a turn for the worse. When the locked up liquidity becomes quite substantial, the owners of the project just “pull the plug” and steal everyone’s funds. This has happened before on Ethereum ( back in 2020 ) and it’s currently running rampant on the Binance Smart Chain. People truly never learn!
The best way to protect yourself from a “Rug Pull” is actually by never participating in those schemes in the first place. The ever prudent granny holding only 5 conservative coins is off course free from this scam, while the nosy and uncareful “Chad” runs into it time and time again. Whenever you see astronomic returns ranging in 3 to 4 digits in percentage profits, think again. This is the same as Bitconnect on steroids!
It’s usually not that easy to spot a potential rug pull, but here are a few things to keep in mind. If a potential project has “anonymous developers”, this is definitely a huge red flag. If a project promises a high percentage of returns in a short period of time ( think Bitconnect ), just run. If a project solely exists in order to “farm” those potential rewards, instead of building a valuable ecosystem, this should definitely set off alarms inside your head. Moving through the DEFI trend will be a totally different ball game than the 2017 ICO craze. This is exactly why it helps to sit down and calmly learn about the ins and outs of the space and how the tech actually works. Only by doing so you will limit your risk in this highly competitive and combustive space.

Mind games

https://preview.redd.it/puqkhskmc5z61.png?width=1024&format=png&auto=webp&s=892204df4fb71550dacac2524afa9d73d1a0ecea
While it’s definitely impossible to describe all the scams and potential attacks in only one article, it’s still easy to distil the basics. Any type of scam or attack eventually plagues the human mind first. It’s all a play on our emotions and our greed. It’s a way of bating us into fast, risky and irrational action. This is why time and time again millions of people will end up losing their money. What can a newcomer do in this space?
First of all the best cause of action would be to relax, have a coffee and think for just one moment. Is the information presented to you too good to be true? Are you being rushed into something that you should definitely think about first? Is your friend trying to sign you up in order to reap some benefits for himself? When you keep in mind that there is no such thing as a free lunch, things suddenly become very clear. This is why you must slow down your mind and “sleep” on any potential emotions that you might be feeling momentarily.
Your best asset perhaps, will be the people you surround yourself with. This space is not for the faint of hearted, but the majority of people dabbling in crypto currency are actually decent and respectful. So it absolutely helps to make plenty of new friends. If you know someone who has been in this space for years, take him/her out to dinner and listen to what they have to say. Take notes and ask plenty of stupid questions. Learn from them and learn from their mistakes.
Aside from this it’s actually of vital importance to educate yourself on a daily basis. Try to rediscover the love of reading and hunger for learning new stuff. Our schools are doing a wonderful job at producing “consumers” and armies of keyboard banging office plankton instead of creators and entrepreneurs. This is why it’s only up to you to educate yourself about the crypto space. Sometimes you might feel lonely, but always remember, even the most diehard veterans were noobs at some point. They also fell victim to scams. They learned and got back on their horses. So shall you. Most important point is to have fun
along the way. There is nothing more wild, immature and unpredictable than the crypto space that’s dominated by memes, own slang and culture. Even if you don’t end up becoming a millionaire during this bull cycle, never forget that they repeat every 4 years! Armed with this new knowledge, skills and experience, you definitely have a shot.
Risk Note: Trading cryptocurrencies is subject to high risks and may result in the loss of your capital. Please make sure you fully understand the risks associated with trading cryptocurrencies and only invest as much as you can afford to lose. Be clear about your investment objectives and experience, and seek advice from an independent financial advisor if necessary. It is your responsibility to determine whether you are permitted to use Tycoons's services under the laws of your country of residence. Investments in cryptocurrencies are not protected by a Financial Services Compensation Scheme.

Def. A monoid that is both cancellative and has no nontrivial invertible elements is a graphic space and an element is a graphic.
Prop. Let W be a graphic space. Then prefix, denoted w < v for w,v <- W is a partial order on W.
Def. Let W,X be graphic spaces. A map e: W -> X that is identity-preserving and non-decreasing in the prefix relation is a homography.
Prop. Let W,X be graphic spaces and e: W -> X a homography. For each w <- W, there exists a unique homography ew : W -> X such that e(w)ew (v) = e(wv) called the shift of e by w. W acts on eW = {ew : w <- W} on the right by ew * v = ewv.
Def. Let W,X be graphic spaces and e: W -> X a homography. The halting set of e is hal(e) = {w <- W: e(wv) = e(w) for all v <- W}. The cohalting set is coh(e) = {w <- W: hal(e^w) = {} }.
Example. Let W be the free monoid in the symbols {0,1,*} and X the free monoid in the set of configurations of the LR parser described in https://en.wikipedia.org/wiki/LR_parser . Let e : W -> X be the homography that reads elements of w left to right and emits the stack, state, input read so far, and accept status configuration of the parser after every generator element of W has been read.
Def. Let W be a graphic space and G <= W minus {1} a nonempty subset of graphics. The set G is graphically independent if for all pairs of finite tuples bar x and bar y in G, Prod bar x = Prod bar y implies x and y have the same length and x_i = y_i for all i.
Prop. Let W be a graphic space and G <= W minus {1} a graphically independent set. Let H = G* be the monoid of finite tuples of elements of G with multiplication concatenation of tuples. The map p: H -> W given by h -> Prod h is an injective homomorphism.
Def. Let W be a graphic space and w,v <- W elements. The greatest common prefix of w and v exists if there is a prefix-least element of { u <- W : u <= w and u <= v }. If it exists, it is unique, and is denoted by gcp(w,v). The graphic space W has the greatest common prefix property if gcp(w,v) exists for all w,v <- W.
Def. Let W be a graphic space. A map . : W -> Re such that w>=0 for all w <- W, w = 0 iff w = 1, and wv = w + v for all w,v <- W is a norm for W, and (W,.) is a normed graphic space.
Prop. Let W be a normed graphic space. Then d(w,v) = inf_{ab = w, ac = v, abc <- W} b + c is a metric on W such that
for all u,v,w <- W.
Def. Let W be a graphic space. Two prefix non-decreasing infinite sequences bar w and bar v in W are mutually cofinal if for all n, there exists N such that w_n <= v_N and v_n <= w_N.
Exercise. Let W be a graphic space. Prove that the binary relation x ~ y for x,y mutually cofinal is an equivalence on the set of prefix non-decreasing infinite sequences of elements in W.
Def. Let W be as above. The projective space P(W) is the quotient of the collection of prefix non-decreasing sequences in W by x ~ y iff x and y are mutually cofinal.
Exercise. Let W be as above. Then W acts (left) on P(W) by w * (v0 ,v_1 ,v_2 ,...) = (w * v_0 ,w * v_1 ,w * v_2 ,...) and Na acts (right) on P(W) by (v_0 ,v_1 ,v_2 ,...) * n = (v_n ,v{n+1} , v_{n+2} ,...).
Let W be a graphic space. Two graphics w,v <- W are orthogonal, in symbols w ⟂ v, if gcp(w,v) = 1.
Def. Let W,V be graphic spaces and e,f : W -> V homographies. Then e and f are mutually cofinal if for all w <- W there exists u <- W such that
Exercise. Let W,V be graphic spaces. Prove that the binary relation x ~ y iff x and y are mutually cofinal is an equivalence on the set of homographies e : W -> V. Prove that if x ~ y then xw ~ yw for all w <- W. Prove that W acts (right) on the set of equivalence classes by shift.
Def. Let W,V be graphic spaces. The Grassmanian Gr(W,V) is the collection of equivalence classes of mutually cofinal homographic maps e : W -> V.
Exercise. Let W be a graphic space. Prove that Gr(Na,W) and P(W) are canonically isomorphic.
Def. Let W be as above. A homographic functional is a homographic map f : W -> Na. The dual space of W, in symbols W*, is the monoid of homographic functionals endowed with the multiplication operation pointwise addition and identity element bold 0 where bold 0(w) = 0 for all w <- W.
Exercise. Let W be as above. Prove that the dual space W* is a graphic space
Example. Let W be the non-negative rationals. The projective space P(W) is a commutative monoid with multiplication pointwise addition.
Exercise. Prove that P(W) above is isomorphic to [0,infty) cup {infty}, the non-negative reals extended with a point at infinity, and is thus not cancellative.
Def. Let W be a normed graphic space. The inner product of two elements w,v <- W is = sup {t: t <- W and t <= w,v }.
Def. Let W,V be graphic spaces and suppose that W cap V = {}. The free product of W and V, in symbols W * V, is defined as follows. Let M_0 be the monoid of tuples in W \ {1_W } cup V \ {1_V } with multiplication concatenation of tuples and identity the empty tuple. For bar t in M_0, define the least terms of bar t to be the tuple obtained by removing adjacent pairs of items from the same factor monoid and replacing them with the product in the same position, until item factor membership alternates. Define multiplication of tuples in least terms to be concatenation followed by reduction to least terms. The free product is the submonoid M_1 = { m <- M_0 : m is in least terms }.
Def. Let W be a graphic space. The inverse of W, in symbols W-1 , is the graphic space V = { w-1 : w <- W } with multiplication w-1 u-1 = (uw)-1 . Here w-1 stands for the ordered pair (w,-1).
Suppose W is a graphic space. Is there a group G and an injective monoid homomorphism phi : W -> G such that for all groups H and all monoid homomorphisms psi : W -> H there exists a unique group homomorphism sigma : G -> H such that psi = sigma o phi?
Def. Let W be a graphic space. An affine function in k variables f : Wk -> W is a map such that f(x_1 ,..., x_k ) = Prod y_i where each y_i is an unknown x_j or a constant in W. Such a function is linear if all y_i are unknown variables. An affine equation is an equation of the form f(bar x) = g(bar x) for affine functions f and g. This equation is linear if f and g are linear.

2016.10.24 20:15 841067 Friendly reminder that Riseup.net is still greatly struggling. If you can help out, it helps us all...

The comrades at Riseup run a fantastic email service for the anti-capitalist community, and do so under great duress. While the funding crisis that occurred in September was averted, they are by no means out of the woods yet. What follows is the text of a recent mail (10/18/16) Riseup sent updating users on the situation:
[en] English - Crisis averted! [de] Deutsch - Krise abgewendet! [pt] Português - Crise evitada! [es] Castellano - ¡Crisis superada! [fr] Français - Une crise évitée [it] Italiano - Crisi evitata!

[en] English

Crisis averted!

Thanks again to all the people who contributed in September in response to our urgent appeal. Your generous response was overwhelming and inspiring.
Many people grew alarmed after reading our last newsletter, and wrote us to ask how serious our situation actually is. Yes, our financial situation has been dire. It is also true that Riseup has weathered lightning strikes, melting computers, internal conflict, illness, national borders, and a car crash. We cannot confirm the alien abduction. Riseup is a quixotic project: the thing we do is persevere, against all reason.
Somehow it works, but this is not a sustainable way to operate. What would it look like if Riseup was run properly? Help tickets would be answered in a timely manner, our services would be more reliable and more secure, and you would not need a different account for each different service. Most importantly, Riseup would be more accountable and more responsive to the needs of the communities we seek to serve. Although your generous support has averted our current crisis, Riseup does not yet generate the donations or the volunteer labor needed for Riseup to thrive.
This means we are going to keep asking for your support! If you missed out, it is never too late to donate. Please visit https://riseup.net/en/donate

Quota increased

Back in June, we said we would put all donations received that month toward increasing quota. We received enough money to double quota, and we will be increasing quota again as soon as we can. A few things to remember about quota:

Security practices for everyone

Computer security is hard, and even big corporations get it wrong most of the time. What is an activist to do? There are four easy first steps that you should take to get started:
(1) Do not open email attachments. Honestly, just don't do it, ever. Email attachments are the single most common cause of security problems. If you must open an email attachment, first contact the sender and confirm that they sent it. In general, you can never trust the identity of the sender [1].
(2) Use a password manager. Some password managers are better than others, but what really matters is that you start using one. Let your beautiful brain fill up with something better than passwords. Remember one long password, and let the computer remember everything else.
(3) Keep your software and operating system up to date. The sad reality is that technology is a never ending treadmill of doom. If you are running old software, you are probably exposing yourself to all sorts of known vulnerabilities that an attacker can take advantage of.
(4) Check out our Better Web Browsing tutorial: https://riseup.net/en/better-web-browsing
[1] Technical note: It is possible to verify the identity of the sender, if the message is signed with OpenPGP or S/MIME. Otherwise, even technically savvy people need to exercise extreme caution (for example, DKIM doesn't prevent domain name homograph attacks, a phishing method using similarly looking characters. Our help page on Phishing - https://riseup.net/en/phishing - has more info).

Krise abgewendet!

Danke nochmal an alle, die im September auf unseren dringenden Spendenaufruf reagierten. Eure großzügige Antwort war überwältigend und ermutigend.
Viele waren nach unserem letzten Newsletter aufgeregt und fragten uns, wie ernst die Situation im Moment ist. Ja, unsere finanzielle Situation war ernst. Auch ist es wahr, dass Riseup unter mehren Blitzeinschlägen, geschmolzenen Computern, internen Konflikten, Krankheit, nationalen Grenzen und einem Autounfall zu leiden hatte. Die Alien-Entführung können wir allerdings nicht bestätigen. Riseup ist ein überwältigendes Projekt: wir halten durch, unter allen Umständen.
Irgendwie funktioniert es, aber es ist keine nachhaltige Arbeitsweise. Wie würde es aussehen, wenn Riseup richtig laufen würde? Hilfe-Tickets würden zeitnah bearbeitet werden, unsere Dienste wären verlässlicher und sicherer und es wäre nicht nötig, getrennte Konten für jeden einzelnen Dienst zu haben. Insbesondere wäre Riseup verantwortlicher und würde besser auf die Wünsche aus der Gemeinschaft reagieren, der wir zu dienen versuchen. Auch wenn eure schnelle Unterstützung unsere aktuelle Krise abgewendet hat, generiert Riseup nicht genügend Spenden, oder freiwillige Mitarbeit, die nötig ist, um Riseup erblühen zu lassen.
Das bedeutet, dass wir weiterhin um eure Untstützung betteln müssen. Es ist nie zu spät zu spenden, bitte schaut auf https://riseup.net/de/spenden

erhöhte Quota

Im Juni versprachen wir euch, alle Spenden in diesem Monat zur Erhöhung der Quota zu verwenden. Wir erhielten genug Geld, um euren Speicherplatz zu verdoppeln und sobald wir können, wird es mehr geben. Zur Erinnerung bezüglich Quota:

Sicherheitspraktiken für alle

Computersicherheit ist schwer und selbst große Unternehmen machen es die meiste Zeit falsch. Was gibt es für Aktivisti zu tun? Es gibt vier einfache Schritte um zu beginnen:
(1) Computersicherheit ist schwer und selbst große Unternehmen machen es die meiste Zeit falsch. Was ist für uns zu tun? Hier vier einfache Schritte um zu beginnen: [1].
(2) Benutze ein Passwortprogramm. Einige Passwort-Manager sind besser als andere, aber was wirklich zählt, ist dass du beginnst, einen zu benutzen. Fülle dein Gehirn mit wichtigeren Dingen als Passwörtern. Merke dir ein langes Passwort und lasse den Computer alles andere für dich merken.
(3) Halte dein System aktuell. Die traurige Wirklichkeit ist: Technologie bleibt eine verhängnisvolle Tretmühle. Wenn du alte Software benutzt, bist du vielen SIcherheitslücken ausgesetzt, von denen Angreifer profitieren können.
(4) Lest unsere Anleitung zu besserem Surfen: riseup.net/en/better-web-browsing: https://riseup.net/de/better-web-browsing
[1] Technische Anmerkung: Es ist möglich, die Authentizität eines Senders zu verifzieren, wenn die Nachricht mit OpenPGP oder S/MIME unterzeichnet ist. Andernfalls müssen auch technisch versierte Menschen sehr vorsichtig sein (DKIM schützt nicht vor homographischen Domainnamen-Angriffen, einer Form des Phishing mit ähnlich aussehenden Schriftzeichen, Unsere Hilfeseite zu Phishing - https://help.riseup.net/de/email/scams/phishing - enthält weitere Infos darüber).

Crise evitada!

Gratidão novamente a todas as pessoas que contribuiram em setembro em resposta ao nosso apelo urgente. Sua resposta generosa foi impressionante e inspiradora.
Muitas pessoas ficaram alarmadas ao ler nosso último boletim, e nos escreveram para perguntar quão séria é de fato nossa situação. Sim, nossa situação financeira tem estado terrível. Também é verdade que Riseup resistiu a tempestades de relâmpagos, derretimento de computadores, conflitos internos, doenças, fronteiras nacionais, e uma batida de carro. Só não podemos confirmar mesmo a abdução alienígena. Riseup é um projeto quixotesco: o que fazemos é perseverar, contra o bom senso e a razão.
De alguma forma isso funciona, mas esta não é uma forma sustentável de operar. Como seria se Riseup fosse gerenciado de forma correta? Os tíquetes de ajuda seriam respondidos em tempo hábil, nossos serviços seriam mais confiáveis e mais seguros, e você não precisaria de uma conta diferente para cada serviço. Mais importante, Riseup seria mais responsável e teria melhor capacidade de resposta com relação às necessidades das comunidades que procuramos atender. Mesmo que sua ajuda generosa tenha evitado a crise atual, Riseup ainda não gera as doações ou o trabalho voluntário necessário para prosperar.
Isso significa que vamos continuar pedido sua ajuda! Se você ficou de fora, nunca é tarde demais para doar. Por favor visite https://riseup.net/pt/donate

Cota aumentada

Lá atrás, em Junho, dissemos que direcionaríamos todas as doações recebidas naquele mês para aumentar as cotas. Recebemos dinheiro suficiente para dobrar as cotas, e vamos aumentar as cotas novamente assim que pudermos. Algumas coisas para se lembrar sobre cotas:

Práticas de segurança para tod@s

Segurança computacional é difícil, e mesmo grandes corporações erram na maioria das vezes. O que ativistas devem fazer? Existem quatro primeiros passos simples que você deve dar para começar:
(1) Não abra anexos de email. Sério mesmo, simplesmente não os abra, nunca. Anexos de email são a causa mais comum de problemas de segurança. Se você precisa abrir um anexo de email, primeiro entre em contato com quem enviou para confirmar que a pessoa realmente o enviou. Em geral, você não pode nunca confiar na identidade de quem enviou [1].
(2) Use um gerenciador de senhas. Alguns gerenciadores de senhas são melhores que outros, mas o que realmente importa é que você comece a usar um. Deixe seu cérebro encher com algo melhor do que senhas. Lembre de apenas uma grande senha e deixe o computador lembrar de todo o resto.
(3) Mantenha seus programas e sistema operacional atualizados. A realidade triste é que a tecnologia é uma esteira infinita cheia de desgraças. Se você estiver usando programas velhos, você provavelmente está se expondo a todo tipo de vulnerabilidades conhecidas as quais um atacante pode tirar vantagem.
(4) Verifique nosso tutorial para melhorar sua navegação na rede: https://riseup.net/pt/better-web-browsing
[1] Nota técnica: É possível verificar a identidade de quem enviou, se a mensagem estiver assinada com OpenPGP ou S/MIME. De outra forma, mesmo pessoas tecnicamente experientes precisam ter um cuidado extremo (por exemplo, DKIM não evita ataques homográficos em nomes de domínios, um método de phishing que usa caracteres similares para confundir. Nossa página de ajuda sobre Phishing - https://help.riseup.net/pt/email/scams/phishing - contém mais informações).

¡Crisis superada!

Gracias de nuevo a toda la gente que contribuyó en Septiembre en respuesta a nuestro llamada urgente. Vuestra generosa respuesta fue sobrecogedora e inspiradora.
Mucha gente se alarmó tras leer nuestro último boletín, y nos escribió para preguntarnos cómo de seria es nuestra situación. Es cierto, nuestra situación financiera ha sido desesperada. También es verdad que Riseup se ha curtido con rayos, ordenadores fundidos, conflictos internos, enfermedades, fronteras nacionales, y un accidente de coche. No podemos aún confirmar la abducción alienígena. Riseup es un proyecto quijotil: lo que hacemos es persistir, contra toda razón.
De alguna manera funciona, pero esta no es una forma sostenible de operar. ¿Cómo sería si Riseup funcionase adecuadamente? Los tickets de ayuda sería respondidos en buen tiempo, nuestros servicios serían más fiables y seguros, y no necesitarías una cuenta para cada diferente servicio. Más importante aún, Riseup sería más responsable y receptivo a las necesidades de las comunidades que buscamos servir. Aunque vuestro generoso apoyo ha evitado la crisis actual, Riseup no genera aún los donativos o el trabajo voluntario necesario para prosperar.
¡Eso significa que vamos a seguir pidiendo vuestro apoyo! Si perdiste la ocasión, nunca es demasiado tarde para donar. Por favor visita: https://riseup.net/es/donar

Aumento de cuota

En junio, anunciamos que invertiríamos todas las donaciones de ese mes en incrementar la cuota. Recibimos suficiente dinero para doblar la cuota, y volveremos a incrementar la cuota tan pronto como podamos. Algunas cosas para recordar sobre la cuota:

Prácticas securitarias para todas

La seguridad digital es difícil, e incluso las grandes corporaciones cometen errores la mayor parte del tiempo. ¿Qué puede hacer una activista? Hay cuatro pasos fáciles que deberías tomar para empezar:
(1) No habrás adjuntos. Honestamente, simplemente no lo hagas, nunca. Los adjuntos son la causa única más común de problemas securitarios. Si tienes que abrir un adjunto, primero contacta la remitente y confirma que lo enviaron. En general, nunca puedes confiar la identidad de la destinataria [1].
(2) Utiliza un gestor de contraseñas. Algunos gestores de contraseñas son mejores que otros, pero lo que realmente importa es que empieces a usar uno. Deja que tu cerebro se llene de cosas más hermosas que contraseñas. Memoriza una contraseña larga y deja que el ordenador recuerde todo lo demás.
(3) Mantén tu software y sistema operativo al día. La triste realidad es que la tecnología es una maldición sin fin. Si utilizas software viejo, probablemente estás exponiéndote a todo tipo de vulnerabilidades conocidas que un atacante puede utilizar.
(4) Consulta nuestro tutorial para Una Mejor Navegación: https://riseup.net/en/better-web-browsing (sólo disponible en inglés por el momento)
[1] Nota técnica: es posible verificar la identidad de la remitente, si el mensaje está firmado con OpenPGP o S/MIME. Sino es así, incluso gente entrenada técnicamente tiene que tomar extremadas precauciones (por ejemplo, DKIM no evita ataques homográficos de nombre de dominio, un método phishing que utiliza caracteres de similar apariencia.

Une crise évitée

Merci à toutes les personnes qui ont contribué en septembre après notre urgent appel aux contributions. La générosité de vos dons est à la fois frappante et inspirante.
Beaucoup d'entre vous ont été apeuré-e-s à la lecture de notre dernière lettre d'information et nous avez écrit pour nous demander à quel point notre situation était mauvaise. Oui, il est vrai que nos finances étaient critiques. Il est également vrai que Riseup a survécu à la foudre, à la destruction d'ordinateurs, aux conflits internes, à la maladie, aux frontières étatiques et à un accident de voiture. Nous ne pouvons pas confirmer l'enlèvement d'un-e des notres par des aliens. Riseup est un projet à la Don Quichotte: contre toute attente, nous persévérons.
Cela fonctionne d'une certaine manière, mais ce n'est pas un façon pérenne de fonctionner. À quoi ressemblerait Riseup si les choses fonctionnaient correctement? Nous réponderions aux tickets d'aide rapidement, nos services seraient plus stables et plus sécuritaires et vous n'auriez pas besoin d'un compte différent pour chaque service. Plus particulièrement, Riseup serait plus redevable et plus à l'écoute des besoins des communautés que nous aidons. Même si votre généreux support nous a aidé à traverser cette crise, Riseup n'as pas encore les ressources financières ou le travail bénévole pour s'épanouir complètement.
Cela veut donc dire que nous allons continuer à vous demander de l'aide! Si vous n'avez pas eu l'occasion de faire un don, il n'est pas trop tard! Allez faire un tour au https://riseup.net/fdonate.

Des quotas plus grands

Nous vous avions annoncé que tous les dons reçus en juin allaient être utilisés pour augmenter les quotas. Nous avons reçu assez d'argent pour doubler les quotas et nous allons les augmenter encore dès que possible. Voici quelques trucs à se rappeler à propos des quotas:

Des pratiques sécuritaires pour tout le monde

La sécurité informatique est difficile et même les grandes compagnies se trompent la plupart du temps. Qu'est-ce qu'un-e activiste peut faire? Voici quatre étapes de base pour vous lancer:
(1) N'ouvrez pas les pièces-jointes dans les courriel. Pour de vrai, ne les ouvrez jamais. Les pièces-jointes sont la cause la plus importante de problèmes de sécurité informatique. Si vous devez ouvrir une pièce-jointe, prenez la peine de contacter la personne qui vous a envoyé le courriel en premier pour vérifier que c'est bien elle qui vous l'a envoyé. En général, vous ne pouvez jamais faire confiance en l'identité d'une personne qui vous envoie un courriel [1].
(2) Utilisez un gestionnaire de mots de passe. Certains gestionnaires sont meilleurs que d'autres, mais le plus important est d'en utiliser un. Laissez votre merveilleux cerveau se remplir d'autre choses que des mots de passe. Rappelez-vous d'un seul long mot de passe et laissez votre ordinateur se rappelez des autres.
(3) Gardez vos programmes et votre système d'exploitation à jour. La triste réalité est que la technologie est un tapis roulant de la mort sans fin. Si vous utilisez des vieux programmes, vous vous exposez à toutes sortes de vulnérabilités que des personnes malicieuses peuvent exploiter.
(4) Allez faire un tour sur notre tutoriel pour améliorer votre navigation sur le web: https://riseup.net/fbetter-web-browsing
[1] Note technique: Il est possible de vérifier l'identité d'une personne qui vous envoie un courriel si le message est signé par OpenPGP ou S/MIME. Sans cela, même les personnes qui s'y connaissent doivent faire preuve d'une grande précaution (par exemple, DKIM n'empêche pas les homographes de noms de domaines, une méthode qui utilise des caractères similaires. Plus d'infos sur notre page d'aide sur l'hameçonnage (phishing) - https://help.riseup.net/en/email/scam/phishing ).

Crisi evitata!

Grazie ancora a tutte le persone che hanno contribuito nel mese di settembre in risposta al nostro appello urgente. La vostra generosa risposta è stata travolgente e motivante.
Dopo aver letto l'ultima newsletter, molte persone si sono allarmate e ci hanno scritto chiedendoci quanto la situazione fosse effettivamente grave. Sì, la nostra situazione finanziaria è stata disastrosa. E' anche vero che Riseup è stata colpita da scioperi a sorpresa, computer che si sono fusi, conflitti interni, malattie, confini nazionali e un incidente d'auto. Non possiamo confermare un rapimento da parte degli alieni. Riseup è un progetto visionario, idealista e romantico: quello che facciamo è perseverare contro qualsiasi raziocinio.
In qualche modo funziona, ma questa non è una maniera sostenibile di operare. Come sarebbe Riseup se le cose funzionassero bene? I ticket di richiesta di supporto riceverebbero risposte in breve tempo, i nostri servizi sarebbero più affidabili e sicuri e voi non avreste bisogno di usare account differenti per i vari servizi. E ancora più importante, Riseup sarebbe più responsabile e reattivo alle necessità delle comunità alle quali cerchiamo di dare servizio. Sebbene il vostro generoso aiuto ha evitato la crisi attuale, Riseup non genera ancora le donazioni o il lavoro volontario necessari a per prosperare.
Questo significa che stiamo per chiedere di nuovo il tuo supporto! Se ti sei fatto sfuggire l'occasione, sappi non è mai troppo tardi per fare una donazione. Visita https://riseup.net/it/donare

Spazio per la posta aumentato

In giugno, dicemmo che avremmo voluto usare le donazioni ricevute nel corso di quel mese per aumentare il limite massimo di spazio per la posta elettronica. Abbiamo ricevuto abbastanza denaro per raddoppiare lo spazio e l'aumenteremo di nuovo appena possibile. Un po' di cose da ricordare riguardo lo spazio disponibile per la posta:

Pratiche di sicurezza per tutti

La sicurezza informatica è un tema difficile ed anche le grandi aziende spesso sbagliano. Cosa può fare un attivista? Per iniziare ci sono quattro facili passi che devi fare:
(1) Non aprire gli allegati dei messaggi di posta elettronica. Davvero, non farlo, mai. Gli allegati delle email sono la causa più comune dei problemi di sicurezza. Se proprio devi aprire un allegato, prima contatta il mittente e chiedi conferma che l'abbia realmente mandato. In generale, non devi mai fidarti dell'identità del mittente [1].
(2) Usa un password manager. Alcuni sono migliori di altri, ma quello che è più importante è iniziare ad usarne uno. Lascia che il tuo splendido cervello si riempia di cose migliori delle password. Ricorda solo una password molto lunga e lascia che il computer si ricordi tutte le altre cose.
(3) Mantieni il software ed il sistema operativo aggiornato. La triste realtà è che la tecnologia è un tragico tran tran senza fine. Se usi software vecchio, ti stai probabilmente esponendo a tutte le possibili vulnerabilità conosciute delle quali si potrebbe servire un possibile aggressore.
(4) Dai un'occhiata al nostro tutorial Better Web Browsing: https://riseup.net/en/better-web-browsing
[1] Nota tecnica: è possibile verificare l'identità del mittente se il messaggio è firmato con OpenPGP o S/MIME. Diversamente, anche le persone più sagge dal punto di vista tecnico devono esercitare la massima cautela (per esempio, DKIM non impedisce gli attacchi omografici sui nomi dei domini, un metodo di phishing che viene fatto attraverso l'uso di caratteri simili nel costruire i nomi dei domini. La nostra pagina di help sul Phishing - https://riseup.net/en/phishing - ha ulteriori informazioni).

2014.09.11 23:14 DoubleNabla The Tales of the Magic Mimicry Variable or: $x !== $x

So, I guess everyone here knows what happens when you use an undefined variable in PHP.
php> echo $foo." bar"; PHP Notice: Undefined variable: foo in php shell code on line 1 bar 
Yeah... it inserts an empty string and emits a notice. Barewords (a.k.a. undefined constants) are even better, PHP will just use the name of the constant as a string.
php > echo foo." bar"; PHP Notice: Use of undefined constant foo - assumed 'foo' in php shell code on line 1 foo bar 
Let that sink in for a while.
I'd say that's insane enough as is, and opens up a lot of potential for both typos and more malicious actions.
But that's not it. PHP also allows Unicode (apparently any codepoint which isn't a reserved character or an ASCII control code) to appear in constant and variable names:
php > $你好 = "hi!"; php > echo $你好; hi! 
The combination of these two misfeatures allows for some truly diabolical backdoors (as well as inexplicable bugs in the fashion of 2+2 == 2). Essentially, you can replace variables with undefined (or different) ones which look exactly the same, and all you get is a notice. This can basically be done in two ways:
  1. Homograph attacks: e.g. replacing a latin a with a cyrillic а:
    $path = "/vawww/foo"; echo $pаth."/usesupplied/path"; // prints /usesupplied/path, and emits a notice 
    Another interesting idea is using the alternative dollar signs in place of the normal $ variable prefix — suddenly, you have an undefined constant that looks like a variable, but will evaluate to a string containing its name...
  2. Inserting invisible or almost-invisible characters. The worst of those is probably U+2060 word joiner, which is completely invisible, even in most editors which show whitespace.
    // let's write a secure random number generator $rnd = openssl_random_pseudo_bytes(100); // most likely secure $today = date('c'); // extra entropy can't hurt! $super_secure_rnd = hash("sha512", $r⁠nd.$today); // oops, that's actually $r\u2060nd, which is undefined, // i.e. NULL, and the result depends only on the current time... 
    Both the code and the results still look okay at a cursory glance.
Oh, and as I mentioned hash()... that's another one of those fail-never-thus-double-deadly functions (I'm sure this has been mentioned here previously):
php > var_dump(hash("lolphp", "foo")); PHP Warning: hash(): Unknown hashing algorithm: lolphp in php shell code on line 1 bool(false) 
Figuring out what the highly secure shа512 — with a cyrillic а — would do is left as an exercise for the reader. But hey, at least it's not a notice.
Bonus points in the code-review-dodging discipline are awarded to 2. given that I'd guess most diff tools will either not show this at all, or make it look like an innocent whitespace or linebreak style change.
Text-direction marks and such would most likely work as well, and certain diacritics might also be nice, especially if your IDE/console font can't display them.
I haven't tried invalid UTF-8 sequences yet — I don't think I even want to know.
However, I've noticed that the syntax highlighters in some editors (e.g. vim, as well as 3v4l.org) don't recognize any non-ascii variable names. Sometimes, two wrongs do make a right.
The safest thing to do would of course be to permit non-ASCII characters only in strings and comments. Or you could put some thought into it and do it properly, i.e. exclude non-printable characters:
Python 3.4.1 (default, May 19 2014, 17:23:49) >>> 你好 = "hi!" >>> print(你好) hi! >>> boobytrap⁠ped = "haxxor" File "", line 1 boobytrap⁠ped = "haxxor" ^ SyntaxError: invalid character in identifier 
(I didn't test if it does unicode normalization, but it's Python, it would just throw a NameError otherwise.)
In short, these unicode identifiers look like a typical PHP feature. Someone else has it, we need it too! (But don't you dare look at how they did it, or you might risk doing it properly.) Side effects? Unintended consequences? Unforseeable interactions with other... specifics... of our language and interpreter? Fuck that noise.
I can excuse falling victim to Unicode traps to some degree, but why the fuck would anyone think simply ignoring the use of undefined variables, and doing something completely insane for undeclared constants, could possibly be a good idea?
Granted, you still get a notice, but a) who reads those and b) as part of a backdoor, you could certainly hide an innocent error_reporting call somewhere (0xF7 — "make sure we catch all errors!")
Here's some working code.
TL;DR: var_dump($foo === $foо); // bool(false) *mic drop*

2014.06.11 22:42 Jaabi Thread of Fitness, Daily: Sports Cup Edition

Everyone's welcome! Welcome to Jaabi's thread of fitness, daily, that is! :D
In order to remind myself and others of keeping up with the exercise and creating a space so the people of the Plounge can discuss their routines and other exercise related things.
Here are some useful workouts you can try, which have various settings that adapt to your fitness level.
You may also want to check out:
JIVEprinting made a fitness game centered around endurance. It's an interesting game, so I'd check it out and see if it's the kind of thing that would fit in my exercise goals, if I were you. If you're just starting up in your exercises, then I would not recommend you play this game. It's intense, but you can scale it down to whatever weight you need. This is just advertisement, of sorts, yes, but I think some of you would like it! Will update it when the full game is "released", so to speak. If you do end up playing it, have fun!
Also, there are three people who post these Daily Fitness Threads: unluckysonofagun , Zanorfgor , and myself, Jaabi , so keep on the lookout for these DFTs from these guys!
Remember to let your muscles cool down a bit between work outs, you can easily replace one for the other! Remember that rest is important!

Hello, everyone! How was your day thus far? Mine was alright. Got a short day at work, so I had some more time than usual to unwind! :D
My near-homograph for "strong burst of air" aside, now it's time for the topic! :D Because of the change in the header, footer, and filly AJ (all football- or soccer-themed now), what sport do you enjoy playing?
For me, it's football/soccer. Why? My family started me off there. Heck, I even joined a children's soccer team when I was a kid. I don't play it a lot anymore except for when my family invites me, but I do enjoy it, especially when people make awesome plays. I don't care who wins, actually. I just want to see awesome plays when I'm playing it or even if it's just on the TV.
Whether or not you use sports to exercise, keep up those exercises and being generally healthy, everybody! :D

2011.02.28 03:41 tonytwotoes TIL: "USE" is a Heteronym

ex1. The best use for the word is in a sentence.
ex2. However, when you use the word this way it sounds different...
I did a little research and this is something i found:
Heteronyms are a type of homograph that are also spelled the same and have different meanings, but sound different.
Sources: The definition I found and the example
EDIT: Thank you more_exercise for pointing out my typo and assuming i was copying Mr. THE_THE
