"In fact, we can show that the spreads must widen to be larger than the tax itself being applied. If there’s a tax of 3 bps on a trade then no one’s going to trade at a spread of less than 3 bps."

6bps. To market make a spread you have to buy AND sell. Tax is charged twice at each end.

The intermediaries are charged the tax twice, which means the end consumer (investors, pension funds, whatever) will be charged (at least) three times. Once directly, and twice indirectly because market makers will have to widen their spreads by at least that amount.
> I think it became a hit as a natural consequence of being so good. He had to do almost no work on promotion, iirc. But I think he was a fairly popular gamedev (or at least not-unknown) before he made Papers, Please.

Looking at it a little cynically for the moment ... in the old days, the main bottleneck that prevented everyone from having their own commercial computer game was money and juice with publishers, while the second-place bottleneck was juice with console manufacturers. Now those factors are much less restricting than before, so everyone has their own indie game. ;) But that means there are many, many more games than the maximum number that can ever achieve significant sales and attention. So the new bottleneck is public attention, and the new king gatekeepers are the gaming media (including Penny Arcade, Let's Players like Totalbiscuit and so on), who can direct the public's attention to your game. So which players are ahead in the new game? Guys with gaming-media juice, either through having gaming-industry recognition or being ex-journalists themselves. Step forward Tom Francis (PC Gamer -> Gunpoint), Jim Rossignol (Rock, Paper, Shotgun -> Sir, You Are Being Hunted) and Lucas Pope (Naughty Dog -> Papers, Please). Now that is a little too cynical, because the new game does seem to be significantly fairer to people who simply make (or would be able to make given funding etc.) a game good enough to deserve attention, and certainly Gunpoint and Papers, Please are notably good games (I haven't played Sir yet). (I should also emphasise that I'm not any kind of expert here, I'm just looking at the situation from the outside.) But I think there's likely some truth to it.
good point. but i do think that my setup works stable and safe for me.

however, i had added the disclaimer because others might be facing a different situation and therefore they are warned.
The author's thesis was quite intuitively illustrated by the Google AdSense "Heat Map", which depicted a schematic of your typical web page, with a header, navigation bars down both sides, a footer, and some blocks where the content lay.

Heeding the advice of the Heatmap by placing one's Ad Units in the "Hot Spots" on one's old pages quite commonly doubled one's monthly revenue.

However the last time I went to look for it at Google's AdSense support site I could not find it. I don't know whether they moved it or took it down.

For your own purposes, try placing important links at different places on your pages, leave them there for a week - as the traffic to most sites tends to be cyclical with a one-week period - then analyze your web server logs so as to determine how many internal referrals to other pages on your own site resulted from each link.

I analyze my own logs with Analog (http://analog.cx/) which is powerful and configurable but has a steep learning curve. If you don't have the headspace to Read The Fine Manual, there are many fine competitors readily available.

Each subsequent week, move each of those experimental links to a distinctly different place on your pages.

Upon finding the most-effective placement for each link, put all the links in their best places, then try altering their presentation: text color, typeface size and style, backround color and the like.

Once you've found the best combination of everything, you will be in a good position to earn some coin via PPC ads.

I myself for three solid years earned $3,500.00 per month on the average, $5,000.00 for two different months, with just two Ad Units on just one single quite lengthy, well-researched piece on copyright law:

>Do you have more info on Facebook "datamining IM conversations?"

Sure, the post I am echoing is in reference to Facebook "scanning" messages and relationships for criminal activity[1], as well as the suit filed at the end of last year[2] alleging that Facebook datamines messages for URLs to use as part of its ad targeting data. We'll have to wait and see if these allegations are true and whether it implicates the company's constant decree with the FTC[3], but Facebook has already confirmed that it does in fact scan private messages for "anti-spam" purposes[4], even blocking links to thepiratebay iirc.

Making money from pure trading revolves around information asymmetry, and ability to store goods - most of the time this is really good, because it helps to motivate people with clever ideas to put them into practice.

The problem with HFT is that practically speaking, the value of a company can't change in timeframes shorter than a couple of hours (barring exceptional circumstances like a big announcement). So a HFT firm is not actually benefiting from information asymmetry about the product of the company being traded or real-world conditions, it is benefiting from information asymmetry about the conditions at the exchange. In theory this is transferring money from subject-matter experts to experts in how exchange servers & the local fiberoptic grid works.

I'd be alone in a room of HF traders, but this isn't useful economic activity vs. subject matter experts making money.

I don't understand all the arguments about 'liquidity', I don't see why a slight price spread is a bad thing; provided that I can sell stock in an hour or so. There isn't a magic 'efficient price' determined by the gods of the market - it is whatever the buyer is willing to pay.

That doesn't really help. Many symbols already have an artificially wide spread of 1 cent (they could have lower spreads if they were allowed to). Forcing spreads wider would reduce volume and increase per-trade profit for market makers (read: HFT). I'm not sure which factor would dominate, but it would be unlikely to have a big impact on the market makers' bottom lines. On the other hand, retail investors would enjoy the privilege of paying wider spreads,
Maybe you can try a few rungs down the ladder?

Based on experience you should not do 01_script_a.py, 02_script_b.py, ... But rather do 010_, 020_, 030_, ... . This way you can squeeze in some initially unaccounted script in the correct location without renaming the others.

Bit of a red herring to say this matters to individual investors though - compared to income tax it is meaningless, and if the share is expected to pay long term dividends it is not big.

It discourages day-trading on stock, but it won't do too much damage to mid/long term investors. It might actually encourage companies to make good mid-long term decisions.

EDIT and the two endpoints can trade directly with a spread smaller than 6 bps if they are that price sensitive.
One could argue that jingoistic chest beating, on both sides of the divide is lamentable.Would we not do well to remember the unprecedented difference between our world today and that of the past; all our nations are more tightly entwined, economically, socially, culturally. Understanding and promoting this mutual dependence seems crucial and pressing to me. Can World Wars be won in this day and age? Is there any rational alternative to our peaceful mutual coexistence (a messy, muddled morass of a coexistence but one none the less). All this rampant 'nationalism' from all camps is dangerous, IMHO. Remember how the cosmopolitan european community was destroyed by World war 1 and a shift to nationalism, xenophobia and prejudice filled the void. Can we not learn from our collective past?
Market makers have been making money for as long as markets have existed. In financial markets, there are now fewer of them, competing for smaller profits, and they use computers to trade.
I dunno, if you've got a good API, server-side HTML rendering is just another client, just like client-side rendering would be.

The trap a lot of developers fall into is going around the existing API for server-side applications though, thinking they'll get more performance by (for example) going directly to the persistence layer. That's how most server-side apps are written, actually; api and front-end tightly coupled.
I find the mouse forces you to hold it at a slant, very different to the demo videos you'll find in System Preferences for the mouse. The right-click functionality is there, but it's hidden and the stiff nature of the protective shell means if you right-click on the far far far right of the mouse, the left click actually gets engaged.

Not a great design. I might dig out the Belkin bluetooth mouse instead.

Indeed.co.uk is an excellent job search engine but from what I have noticed it's flooded with ads coming from recruitment agencies. I wouldn't be surprised if quite a lot of those job postings would be replicates, posted by different recruiters/agencies.

Also, there seems to be quite a lot of confusion about node.js around recruiters/job postings. It is often being treated as another *.js library and put under front-end category.
Suppose we made regular businesses wait an extra week to receive shipments. What if you had to wait an extra minute to launch a new server on AWS?

I think the difference is more nuanced, arguable either way. Users effectively have some sort of agreement with Facebook where Facebook get their data. Realistically this is not something they are really aware of. They use a free service. Facebook collect and use the data in way they don't understand.

Do they have that agreement with ISPs? Phones companies? Supermarkets with facial recognition software to track shopping habits?

Since a lot of this data tuff is about aggregation, entities sharing data can have a lot of consequences. If you have Facebook, Whatsapp & email data for a significant number of people, then you have a lot of data about people that aren't signed up to any of those.

I think trying to categorize data privacy issues into "users agreed to." is pedantic in a way that gets away from the reality of what is going on. The hacking vs just recording may have legal importance, but I don't think

I've said this before, the digitization & aggregations of so much data is a bigger world changing issue. The Snowden/wikileaks affairs are a strange double example. The US agencies have their data stolen and spread around because it's "data." This data is largely information about how they steal data. You can't keep your secrets from them and they have trouble keeping their secrets data from you.

"Voluntary" or "consensual" mean different things in different contexts.
I'm guessing that's what the Wikipedia article means by "modern": able to work on most any surface, not just a special mat.
No, the distinction between democracy and republic was well established before Madison. It appears in James Harrington's works. It also appears in works of Montesquieu, Rousseau, Tocqueville, and even Aristotle. I could find the precise quotes of their works to support my point, but I'm not at home. If you're into this kind of stuff, I recommend Bernard Manin's The Principles of Representative Government. Sounds boring but it's actually a great book.
> The real "problem" as I understand it is that some people get information sooner than others and can profit from it

That's backwards. Exactly synchronising the dissemination of information is a hard problem. HFT leverages even small sub-second differences.

Even simple physical factors (i.e. the speed of light) mean that being closer to the exchange is highly desirable as this will mean getting the information sooner. People did not create the phsyics of that problem.
Your point about compiled python libraries is correct in principle, but it's worth pointing out the GAE python comes with PIL and LXML (and a bunch of other libraries) pre-installed these days:

See https://developers.google.com/appengine/docs/python/tools/li... for a complete list.

But,yea if you need a library that's not on that list and uses native extensions, then you're kind of screwed.
You can have very different opinion about friction depending on where it is. You won't use the same lube that you use on your crankshaft on your brakes. At least I hope so - the last time I saw "My brakes are screeching I greased them" was hilarious, but that is what bumpers are for.

So we want lower barriers to entry in trading and moving capital to the productive sectors of the economy and smarter trades. That is why the transaction tax could be helpful - we want to move the largest amount of capital to the economy and not the maximum possible numbers of transactions.

Somebody's pretty angry. Gooooood :)

I see no serious argument in this text. I mean, my god, if we tax them, their prices will rise?! I've never heard of anything like that! :D And everything is so weakly argumented, just a couple of expert terms are thrown around, while the majority of the text deals with attacking segments of opposing views he disagrees with. All in all, very emotional and weak.

And I love his explanation of how this Great Recession came to be. One of the most manipulatively simplified descriptions I've ever heard.
That's a smart, strategic idea. Mainstream sites -- outside of Russia but that Russians still use often -- that are willing to stand in solidarity and risk being blocked would be dramatically important. Without outside support, the overwhelming majority of a Russian public will continue to become even more acculturated to censorship and a state's chilling effects. This is already the case. However, it will only get worse unless complacency reaches a tipping point of jolting awareness.

Needless to say, several organizations would be willing to maintain updated blocked (accepted) lists. The important part is not allowing a proxy to be abstracted from the main site; otherwise, isolated javascript would be the blocking target, which would defeat the effects ever being noticed.
It's like BASIC all over again.
I feel it's worth pointing out that Facebook won't lock you up without trial in a secret prison, torture you and violate every human right you have because of something you think.

What do shares have to do with anything? They are a small part of the picture. The spread on the e-mini S&P is currently 0.25, and it is trading at 1800. So 1/7200 is roughly 1.5 bps. This will increase the spread by (at least) 6 bps to 7.5bps, then charge you another 3. So spreads five times bigger. Instead of trading say 1810.00/1810.25, it will be trading 1810.00/1811.25. Do you get it yet? No one will trade. And the comical part is that they project supposed revenues based on current trading volumes.

Also, I've missed the best part so far, when I mentioned that you get charged three times in my first post, that was just to get into a trade. So end-user will get charged at least 6 times per roundtrip (twice directly, four times indirectly through widened spreads).
Everyone who does DB update should understand idempotence and how to undo their changes. I like the approach the author provides, but calling it version control is inaccurate. This is change management and it's a completely different discipline with its own body of knowledge.

Man, I wish people would stop repeating that "path of least resistance" thing about electricity. It makes it so much harder to understand how electricity actually works when you've been hearing that lie your whole life. It's also the kind of misinformation that gets people hurt.

Current flows through every path, always. Otherwise, parallel circuits wouldn't work.
I could join the bigger battery crowd. We are stuck with the same battery life an iPhone 1 had. The incremental battery and efficiency gains are consumed by displays and more and more apps running in the background and we still don't have a phone that can last a day on moderate burn.

Or just make a standard for batteries like AA and just let people replace them. Its revolutionary idea that has been around for the last couple of decades.

I'd hardly call Press TV "independent" - it's state-funded and apparently strongly linked to the Revolutionary Guard - http://en.wikipedia.org/wiki/Press_TV.

Your Guardian link describes Ofcom - the TV regulator in the UK - offering two alternatives to Press TV to retain its license in order to comply with the requirement that the license is held by the same entity as that providing editorial oversight. It also mentions that Press TV was fined for airing a clip of an interview carried out under duress. Regulation is not censorship.
I'm sure not automatically trading hundreds of times per second will not impact their business (unless their business is trading faster than somebody else).
> So what does it take to be a genius then?

A genius is a person who is capable of incredible leaps of understanding and originality. That's difficult to measure so we recognise geniuses through the work they achieved...the theory of evolution marks Darwin as a genius, and relativity does the same for Einstein. Jobs may well have been a genius, but his achievements aren't at the level most people think of as genius.
Sorry but if I compare what GPUs Apple systems have with what I can get for the same price for other systems, it is not that great.

When measuring available video RAM, shader levels and OpenGL version support, Apple systems don't fare that well.
