I have twice before started partnerships, however, most of my newer ideas would require some tech experience of which I have none.

Get some. Its not as daunting as it seems at first. It will go a huge distance in convincing others that you're serious. Even the poorest half-working demo is far more than most people start with.

With no tech at all, it all too often sounds like you're just looking for a partner to do all the work while you "think big thoughts". (Not saying that this is you or anything, its just that most of the tech-inclined types around here have been on that train once or twice.)

I'm a bit confused, aren't lexers implemented using similar techniques as regular expressions? (i.e: NFA to DFA conversion and DFA minimization).

Or maybe I'm also confusing lexers with lexer generators.
This article is not actually about USB. Neither about Windows 8.

What's interesting is that Microsoft uses model checking on real shipping products. In fact it has been pushing static checker (SLAM and SDV) for years.

Other operating systems including Linux have their own verification projects, but they all appear to stay academic (though look promising).

We can expect more reliable operating systems in this decade. Maybe.
I feel like it's more error-prone. This regexp lexer took me several minutes to get right, and I'm still not totally sure it's bug-free:

>>> replace = lambda text, env: ''.join(env[item[1:]] if item.startswith('$') else item[1:] if item.startswith('\\') else item for item in re.findall(r'[^\\$]+|\\.|\$\w+|\\$', text))
>>> print replace(r'This $line has \stuff \\in it that costs \$50 and some $variables.', {'line': 'LINE', 'variables': 'apples'})
This LINE has stuff \in it that costs $50 and some apples.

If I were to write out an explicit loop over the characters of the string, I would be a lot more sure that I wasn't accidentally dropping characters due to an inadvertent failure to make the regexp exhaustive (I originally forgot the \\$ case! Although that reduces to the empty string anyway) and I wouldn't have to forget and rediscover which lexical category each token belonged to.

And, although it's not present in this case or in all regexp engines, it's a lot easier to accidentally write an exponential-time algorithm in a regexp than in a nested loop. And my experience has been that it's harder to debug it, too.

I don't know about you, but my career is based entirely on my university degree(s). And not because of the piece of paper, either, because of the crapload of stuff I learned at university which I never would have learned any other way.

Many of the people who proclaim that university is useless are programmers. No surprises there -- programming is one of the few marketable skills which you can actually teach yourself from a book. Aeronautical engineering? Not so much.
ELB is cheaper than running your own EC2 load balancer, but ElastiCache is more expensive than the same raw EC2 servers. It makes sense, but I was hoping it'd be as much of a no-brainer as ELB was.
It would be great, really great, if this were priced per-gigabyte of RAM and per-gig transferred. To my mind, memcache should be billed and used more like a CDN.

Until then, this makes sense only for mid-large scale memcache deployments, similar to Amazon's RDS.

You would think they should be able to offer it cheaper, as they will be able organise it to get a lot more users/ CPU usage per server than the usage they would typically get from an average EC2 server.
Just like records, eight tracks and cassettes...
I think that the most valuable advice in this is in the first line, simply learn by doing. I've been wanting to learn to code for well over a year. However, I think I've watched to many videos and done to many guided tutorials...never actually getting enough time doing projects on my own to actually solidify any skills. Thus it feels like I haven't actually learnt anything at all. My day to day work doesn't involve any programming so carving out time to practice is hard, but sooo necessary. I've got my work cut out for me.

> However, the ruling makes clear that if MP3tunes scanned a customer’s music collection and found “Stairway to Heaven” ripped from a CD with a slightly different file size, the company could not simply substitute a master copy. Instead, that customer would have to upload the file.

> While the latter case still seems non-sensical, the ruling still must come as a relief to Google, Amazon and Dropbox.

Come on, how is that non-sensical? It'd be dead simple to set the ID3 tags of any 4MB mp3 file to match the tags accepted for a given song. From what I read, and the legalspeak got pretty heavy so I may have missed it, there wasn't any discussion of audio fingerprinting or more advanced ways to determine two files are the same song.

Want an entire artist's discography? Use a 15KB app which spits out 100 junk MP3 files with the right ID3 tags and submit them to MP3Tunes. If we do what this author considers "sensical," you should get the real music back.
Yeah I gave my 12 year old brother my laptop this weekend and he said he enjoyed it a lot too and was able to complete all the lessons. I had to give him a few pointers here and there but it's only to be expected from a 12 year old kid who's native language is other than English. Having said that, it would be nice to have it in multiple languages, to reach an even larger audience (especially kids, who i think this is very useful for).

The second comment...

I am over the bruises to my ego; I just ignore my mother-in-law completely now. The worst thing though is the impact on my kids. We were making $120K plus two years ago. Now, about $35K. Lost the house. Thankfully still in the same school. That said, the kids went from being respectably comfortable in their cohort to being comfortable if tattered (used clothes, battered rental, same old car, no summer trips, etc.). Thank God they are still young (just started third grade) but we're not having any sleepovers here no matter how much they ask. I am afraid for the social impact on them.

I have a very hard time sympathizing with this person. They ooze entitlement and crave validation in every sentence.

However, I do find that when I let the emails build up over a few hours, rather than answering them as they come in it takes a lot less time to answer them all at once and I can get other work done and be less distracted in between. But sometimes you need to keep checking because something could be important, and the compulsion to just respond is very strong and kills time. Maybe if I knew the deadline on responses (what was urgent) it would be easier. Priority inbox is good, but doesn't really help with this...
> 'square' inherits from 'rectangle', etc. ... It demonstrates the ".. is a .." relationship that inheritance describes perfectly.

Your comment is a perfect example of why this is a terrible way to teach object-oriented design: if your squares and rectangles are mutable, as they usually are in the old shape-hierarchy demonstration, you've just violated the LSP and introduced a subtle bug into your program, in the very first line of your comment. If you understood object-oriented design, you wouldn't do that. You've been tricked into thinking you know how to do object-oriented design, but your sense of competence is an illusion.

For what it's worth, although I don't have any real experience teaching other people to program, I've found that animated graphics that make sounds hold the attention of nontechnical people a lot better than abstract hierarchies of Platonic geometric shapes. I haven't compared them with bird-flocking simulations.

I think the guy doesn't understand copyright:
"There is a general understanding that unless explicitly marked in the contents of the script (the text file that is the Bash program), a Bash script is freely available for use and modification by anyone."

Really?

The fact that bash scripts are not compiled and distributed in a source code form doesn't mean they are not covered by copyrights. Just like ruby, or perl.

I don't know the details, but it is entirely possible that someone copied some scripts around and they are now used anywhere w/o proper redistribution permission.

TRade secrets claims are strange though.
It's true that it's fairly infrequent, but it doesn't follow that it doesn't matter if a language makes it easier. When it's applicable, it simplifies things enormously.

I don't know, but the past turned into a game of Survivor roughly four billion years ago. If it hadn't, we never would have developed cell membranes, let alone multicellularity.

How to validate the attractiveness of your mobile game/app icon?
Hello~

I've already made an iPhone game. I've prepared several versions of icons and hoping to test which icon is the best.

Any good (and cheap) method to test which icon does attract most users? Please advise.

I currently use Admob (the mobile advertising network), where I make advertising banners with icons and choose the icon with most click rate.

Any other ideas?
It's entirely meant as a compliment. There's no way I want an infrastructure supplier to seem hurried. Internally it may have seemed as fast as possible, but externally it was never showed signs of being faster than possible, which is an amazing achievement. For our industry, almost miraculous.

And I think you folks were very smart to start small and improve incrementally. As an example of what I mean, take this Slashdot comment from the EC2 launch a few years back: http://developers.slashdot.org/comments.pl?sid=329797&ci...

Those are all legitimate gripes, and one by one Amazon has knocked them all down. Had you tried solving all of the problems before launching, I imagine you never would have gotten anywhere. The steady pace and it's-ready-when-it's-ready releases are definitely inspiring to me.
This Robert Heinlein quote is perhaps overplayed, but I'm gonna paste it in here anyway in case someone hasn't heard it or just needs a reminder:

"Throughout history, poverty is the normal condition of man. Advances which permit this norm to be exceeded — here and there, now and then — are the work of an extremely small minority, frequently despised, often condemned, and almost always opposed by all right-thinking people. Whenever this tiny minority is kept from creating, or (as sometimes happens) is driven out of a society, the people then slip back into abject poverty. This is known as "bad luck.""
No such a legal obligation, but all three major careers support the warning system (however Softbank has only few phones that can receive the warning messages).

This system uses a feature defined in 3GPP and probably can be implemented in cellular networks in other countries than Japan. However it may need modifications of the software in the network, it may take several years to be fully deployed.

the film is not afraid of violence and definitely earns its rating R Scenes very many activities ranging from very good to excellent and is also very bloody In fact I would even argue that the film is more bloody than the director Marcus Nispel remake of The Texas Chainsaw Massacre and Friday 13 combined In other words you do not want to take your children and disgusted might want to give this a pass because there are some really nasty scenes.
Agreed, the value add isn't very high, especially since the pricing is higher than EC2. Surely there are some economies that could be found on servers with no disks and reduced CPU requirements? I wonder if ECC could even be done away with if they checksummed all the stored values?

It would be a real killer if they had incremental pricing (per-GB-hour) with an adjustable high watermark / replica count, and a name/port-based endpoint that always worked and routed requests to the proper cache server.

It is frequent in some applications, and when programming in languages that encourage you to recur instead of looping (see: functional proramming). Also, recursion is one of the most important concepts of computer science.

I would have liked it a lot more if they launched a Redis like version with persistence storage than memcache. I wonder why they considered Memcache over Redis.
Are those PPP dollars, or exchange rate dollars?
The-illusion-of-asymmetric-insight
Except running memcached on an EC2 instance is not equivalent to the ElastiCache offering. With ElastiCache you are paying for a redundant, managed service that can be scaled and monitored through a few clicks of a webpage or API.

Outsourcing these type of things is potentially justifiable to a developer whose wallet is full and many hats touch the ceiling.
My first thought was: "Only ten?"
This is awesome, and came at just the right time for me!

Last February, in my last semester of college, I heard about an iPad contracting job. I had never done any freelance work before, so I thought it would be a good opportunity to see what it was like. I gave the client a whole-project quote based on some conservative time estimates and an hourly rate a little below the market.

After that I didn't really track hours since they were paying per feature milestone, so when the project was over I had no idea how much time I had actually spent on it. I had planned to write a utility to estimate the time from my Git commits. You beat me to it! (Turns out I'm faster than I thought. :-))

I just finished writing my own time tracking tool, but I may use this instead for projects that can be represented entirely by their git repository.

Some comments:

- I have a lot of repositories, most of them small personal projects or other people's open source projects. Can you let me only import a couple, maybe preferring private and recent repositories?

- The design is very nice

- Can you separate the time estimation from the cost calculation? I'm sure a lot of people are interested in that functionality by itself.

- If I'm going to back-fill estimates, I want to see the diff, but the links to the commit diffs are on the page before you can enter the estimates. Add links to the page where you can enter your own estimates!

> who will complain that testing hurts velocity

I know you were being intentionally facetious here, but this does nicely encapsulate "How Project Managers and Developers Fuck Agile".

Use of velocity outside of calculating capacity and extra demands being placed on the team is broken; yet I've seen Project Managers terrorize their charges by using it as some kind of fucked-up productivity measurement. For a developer, if your estimates don't include time taken to properly test and develop the user stories, you are lying. You're lying to the business, you're lying to the team, and you're hiding technical debt. As a developer, you get final sign-off on how many points you assign to a story - don't fuck up this 'simple' task :-)
