I agree with that but things are getting better. Providers like Internap exists now which has "instantly provisioned" dedicated hardware and a hosting API ( http://www.internap.com/agile/ ). I personally have not had experience with them bu

The hardest part of making a nuclear weapon is acquiring weapons grade (highly enriched) uranium and/or plutonium. The actual designing/making of the bomb itself is relatively trivial compared to the materials enrichment process (you can ea

The article explains how all the passwords were revealed except for "qeadzcwrsfxv1331". Maybe I missed it but could anybody point out to me which method revealed this password? The letters seem to not form any words that I know, and althoug

If you do not manage SSL certificate properly (trust only your server's certificate), a MITM attack can break the system easily. Otherwise I don't think you can intercept the signed message if everything is over TLS.

About the timing attack on HMAC that the article mentions. It takes thousands if not hundreds of thousands of requests to gather the data (and let's assume you can indeed extract the data out of all the noise cause by network latency etc...

Read http://en.wikipedia.org/wiki/Big_O_notation Basically it's talking about time complexity, or how fast does the time it takes to compute the solution grow as the input grows in size.

by jd007 13y ago
It's talking about big O time complexity, which means you have to prove that there can be no faster algorithm. For example comparison sort (so no radix) can be no faster than O(nlogn).

Yeah EC2 is basically a VPS rental, but with a number of services surrounding it to help with ops. So it is more convenient than a pure VPS service, but by no means "takes care" of ops for you. With Heroku you use files to specify your dyno

by jd007 13y ago
In a startup you may not have the luxury of affording both devs and ops. Most of the time you end up having a devops guy who does a lot of both. Compilers are the same regardless of who's using them, but ops needs to be tailored for specifi

Amazon certainly makes a lot of things easier. For example, you still have to manually back up your database and files, but the storage of those files are simplified (S3, which is arguably one of the safest places to store files in terms of

I have no doubt you can do a lot of powerful things with PHP, provided you have the experience and put in the man power + time. But this does not justify the use of PHP now (for new projects), it just means that if you happen to be stuck on

I'm a bit turned off by their (Digital Ocean) features page, in the SSD section, where they implied that SATA means traditional spindle-based HDDs. I kind of expect a cloud server host to know the proper terminology for these things. It's p

the two do not mean the same thing though. the former means the person is not dead, while your version means the person is not harmed. in google's version, the person might have lost a limb or was injured, but still alive. this is not "fine

Quantum computers are still in its infancy, and a lot more work is needed before we can even begin talking about practical, effective use. Consumer market readiness is even further away. It's probably not worthwhile for quantum computing ch

"The harder it is to duplicate and easier to verify, the more liquid it is." What? A 5-year bond is hard to duplicate and very easy to verify, but it's not liquid at all. I'm not sure that this guy knows much about how currencies and assets

Your point is absolutely correct, but your example could be better IMO. It's not fair to compare a desktop chip with 45W TDP with a laptop chip rated at 35W. Not to mention that the newer i7 actually goes up to 3.7Ghz turbo (vs. 2.5Ghz cons

Maybe not the case for SimCity, but for Diablo 3 a lot of game calculations are done server side to prevent hacks in the item drop rate and item duplication. Because Diablo 3 has a real money economy, it's crucial to ensure that the items i

I never said people should not learn basic logic. What I said/meant was that learning to program may shift how people approach problems, in a way that favors logical thinking, which may not be ideal for everybody. Programmers tend to approa

That is not the case at all. I'm not saying that we shouldn't give the opportunity to learn programming to everybody, I'm saying that trying to get everybody to learn programming (which, in the ideal case, the end goal would be pretty much

You are stretching the issue a bit far IMO. Also counting and arithmetic is kind of hard NOT to learn even if you do not specifically learn it from somebody or in school because it is too essential to living in society. Programming is hardl

You imply that logical thinking is a desirable trait for everybody, which may not be necessarily true. I think that programming teaches you a way of thinking that you cannot really get rid of after acquiring it, and though good for a lot of

If I understand MMU correctly, it is merely an address translator and physical memory data fetcher. It cannot process page faults, and when it encounters one, it will have to signal the CPU, because the CPU and the OS on top of it knows how

Isn't it a bit misleading to say that they are getting computation without executing any instructions? It's true that they are not executing any x86 instructions from the CPU, but the MMU is doing all the work by executing its instructions
