Apple Posts $18B Quarterly Profit, the Highest By Any Company, Ever

rioki Re:Tax (219 comments)

Just for people who are incapable of actually putting their arguments of facts, here are the numbers: Net Income is 18,024 and the Taxes payed are 3,869. This turns out to be 21.4%. This is not no taxes, even if the actual figure is rather low.

Apple Posts $18B Quarterly Profit, the Highest By Any Company, Ever

rioki Re:Tax (219 comments)

What is so wrong about selling a good product at reasonable price. Now I will agree with you that Apple devices are spec wise not at the leading edge and price/value wise not the best sell. But they are withing reason comparable to other high end products. What I must give them; or rather Steve Jobs, is the fact that they/he embraced the "it just works" mantra and many people want that. Now I like my Android the way it is: open; but issues with apple devices are only rarely seen. Granted it comes at the cost of buying expensive preapproved and compatible components, instead of bargain components. For all accounts I can not see any real evil doing on the part of Apple; and no walled gardens are not evil...

Jim Blasko Explains 'Unbreakable Coin' (Video 2 of 2)

rioki Re:Another use of Crypto-coin - as gift cards (39 comments)

Um? The only thing that gives the value to a currency is the shared trust in this currency. The "gold standard" or any other shenanigans are/where just smoke an mirrors to reinforce this shared trust. (Especially when going from minted gold and silver coins to paper.) But even the value of gold and silver coins is based on shared trust. Sure you can melt the gold and trade that, but there is not guarantee what the gold price will be in the future or that the next person will accept these coins.

Jim Blasko Explains 'Unbreakable Coin' (Video 2 of 2)

rioki Re:Another use of Crypto-coin - as gift cards (39 comments)

Do you know how bit coin works? How do you "pre-mine" a crypto currency. The mining process is part of the running transactions. If today all bitcoin mining ceased, no transaction would ever be validated. This thing with bitcoin is, there are no tokens that need to be mined. The mining process actually is just a clever way to authenticate transactions in a decentralized manner. That the miner gets something out of it, is just a reward so that people provide the computing power to authenticate transactions. Mining just sounds cooler than authenticating transactions.

The alternative is to use tokens, but these need to be authenticated against a central authority... and that not a crpto currency as we understand it.

Jim Blasko Explains 'Unbreakable Coin' (Video 2 of 2)

rioki Re:ok. i'll play. "my experience is... (39 comments)

That does not compute. Why does a company, any size that is, need to convert heir daily/weekly/monthly earning in on go. What is so wrong about converting the payments into local currency as the payments come in. Sure it may make sense to batch some transfers so that the fees are minimized, but apart for that there is no reason to wait.

In addition this is somewhat self regulating, when a company starts to accept payments in BitCoin, it will start low and slowly grow. When it gets large enough to matter the market will have adjusted to the drain. In addition, if a significant amount is taken out of the market and the people continue paying with BitCoin, it means that they need actually buy BitCoin from other currencies.

The problem that companies face is that, if the services are priced in BitCoin, they don't know how much "real" money they will get. But mostly this is not the case; the services are priced, for example "5 USD payable in BitCoin, as by XYZ's exchange rate".

PC Shipments Are Slowly Recovering

rioki Re:My guess (130 comments)

You know, many engineers actually use the computing power given to them. Granted not all the time, but if a project compiles in five min instead of one hour, that actually means something. The complaining normally starts, because they know that with a better system they would not wait that long. On the other hand MANY other office computer users topped their "maxing out" the machine at around 2005.

How Relevant is C in 2014?

rioki Re: C is primordial (641 comments)

Yes but you would not be able to actually empress this in C. Not possible! The best you could do would be something like:


void set_class_to_blue(Element* ele)
{
        set_class(ele, "blue");
}

foreach(dom, "a", set_class_to_blue);

Any if you inline the code, you can see what it does line for line and translate it to ASM.

Take the JQuery in contrast. That does the $("a") actually do? It creates an object that contains a classifier that may later evaluate to DOM nodes. On this object you then can call function; theses functions then operate on all instances. So the statement $("a").addClass("blue") is semantically equivalent to $('a').forEach(function (ele) {ele.setClass("blue");}). But it is not implemented in the same way. Even if you inline all the JS code, it will be hard to break it down to actual processor instructions (just the VM), because half of the time a semantic construction does nothing useful.

AdNauseam Browser Extension Quietly Clicks On Blocked Ads

rioki Leading by Bad Example? (285 comments)

I am not sure if on purpose or not but their website is a classic example why ads are bad and distracting. Their website is loaded with ads for their campaigns, social media buttons, links to the extensions and stuff. The entire design looks almost like a terrible online magazine, that derides their article just so you will see the ads. It may that it is a bold sarcastic statement or they are hypocrites.

How Relevant is C in 2014?

rioki Re:C is very relevant in 2014, (641 comments)

Perhaps C's greatest weakness is that it places too much trust in the coder, where other languages don't.

THIS is the only reason for C's existence. If solves one problem, remove all barriers between the programmer and the machine and still be a reasonable language. Assembly is the only way to program with less barriers, but that is not a reasonable language. C is useful in those cases where you simple can't trade speed for the programmer switching off his brain.

How Relevant is C in 2014?

rioki Re:C is primordial (641 comments)

Ok I will bite. Now I don't claim that C is on the same level than ASM, but you need to compare it to current languages. Languages like Python or JavaScript, they abstract out almost everything about the machine you are running them on. With C you program against a reasonably close abstraction of the real machine. In many cases you can hand compile the C code to ASM.

Take for example the JS expression $("a").addClass("blue"). This expression written in C would take up something around 100 lines of code, simply because the machine you program against does not understand high level concepts. Even simple concepts like a string are not understood by C.

I love programming in C, but in whole ecosystem of languages it is on the low end.

The Failed Economics of Our Software Commons

rioki Re:Marketshare (205 comments)

There is a certain corundum you need to solve. If you sell your software from the beginning, there is a real chance that nobody will ever buy it. If you open source it it may become a huge hit, but you get not money out of it. Assuming that successful open source projects would also be stellar successes when closed source is nonsense.

Also equating that rich corporations are "ripping you off" since they would have payed you good sums, is also nonsense. If no open source alternative was available and they really needed the software they would have just build it themselves and certainly not payed you. Alternatively some projects just exists because the use of open source make the project viable.

The Failed Economics of Our Software Commons

rioki Re:Marketshare (205 comments)

The FED does not give money to corporations, they primarily interface with the government and banks. It also does not give money, it LENDS money to them. The trick employed here, is that in accounting terms money is added to the active and passive side equally and thus it balances out. Of course this is just smoke and mirrors, since under normal circumstances you actually need to have money to lend it to someone else, but that is not the case at the FED. In addition they get interest on the lending.

Generally I am not opposed to the notion of a central bank that can act as a lender of last resort. But in the case of the FED, "the Federal Reserve is as federal as Federal Express".

A Mismatch Between Wikimedia's Pledge Drive and Its Cash On Hand?

rioki Re:Well (274 comments)

Yea, but writing a PHP application and attaching it to MySQL or PostrgreSQL and caching the entire thing through varnish or zend does not. Remember MediaWiki is basically implemented. All they need to do is scale out.

UK Authorities Launching Massive Child Abuse Database

rioki Re:Secondary application: tracking pedophiles. (150 comments)

Didn't Google offer their ContentID technology for this a few years past? If you take something like that, the actual file hash is irrelevant, you take a "hash" of the content not the bits that make up the file. This mostly solves transcoding and watermarking.

Is Chernobyl Still Dangerous? Was 60 Minutes Pushing Propaganda?

rioki Re:Yes (409 comments)

The effects of radiation is interesting. The SciShow episode Inside the Chernobyl Exclusion Zone is quite interesting on the subject. Sure it's short 4min format, but it introduces the interesting fact that, although some species have suffered gravely, some plants and animals flourish. If you read further into the subject, it gets even more weirder. As for example species that tend to suffer under human civilization, such as the deers and the lynx, suddenly are quite successful; it appears that humans are worse drain than the radiation.

Slack Now Letting Employers Tap Workers' Private Chats

rioki Re:Pretty good idea if it is your computer (79 comments)

The trick is that to use your device in the corporate network you need to install the company's CA-certificate. You need to do that or you can not use . Now as it just happens the gateway router is also a transparent HTTPS proxy that issues certificate for the domains it MITM using that said CA-cert. You can't do much (in the US), since you agreed to the usage terms, that included "monitoring for anomalous behavior".
