The FIRST app that gains control of the screen does not allow other apps do the same. Try it. Open Windows Media Player, play a video, then open VLC and play a video. You'll see that VLC output is pixelated - that's because it's rendering using RGB and not via hardware overlay.
Good tutorial.

After lesson 16 all the instructions disappeared and I was left with a white screen. Tried to go to a different lesson or the restart command but the instructions didn't come back. Couldn't replicate the problem unfortunately.

Inventables a University of Illinois startup.

If you play with several dozen of their materials, you will get several product ideas, some olf which may even have markets!

I think they are trying to provide value through all the normal ways an online reseller would, with a bent for the entrepeneurial inventer market.

At least that'd the impression that I get. For large quantities I would hazard the guess that no party misses out on the pie.
What are the units on this?
Dropbox and Airbnb are two of the most revolutionary products (alongside the iPhone, 802.11b, etc) I have ever used. These two companies, amongst others, are the answer to when people challenge that no "world altering company" will come from a startup accelerator.

Dropbox has literally changed how I (and dozens of my friends) use computers.

Airbnb has opened the door to affordably travel the world. I was going to go to Barcelona for a weekend surfing trip in a week or two, and flights were £100 (from London) and hotels were £75+ per night. With Airbnb, I found an amazing apartment for £30 a night. That is a huge.

Traditionally, you have a hotel room - but that is just a room with no kitchen, meaning eating when travelling almost requires you to eat out, hugely expensive. With Airbnb I can find an apartment with a kitchen, and purchase local produce for lunches and such. Being able to request wifi in apartments is an insanely great feature if you're able to remote work.

I find the Airbnb website pretty bad if I am honest (incidentally, I them tons of feedback on it a few days ago) but I hope they are going to fix it. Asking me where I want to travel and only giving my a search box is mediocre, the benefit of Airbnb is that I can travel to places I have never even heard of, for less than traditional holiday resorts.

A lot of the best startups are the ones were you can use assets to brutally destroy the present market incumbents, and Airbnb is a perfect example of using a hotels largest advantage (erm, hotels) as their weakness. Airbnb will obliterate all present hotel companies eventually.

I'd bet money that Airbnb will be the largest exit of all batches Pre-2010 (which is when various friends' startups (and myself) were accepted, and well, we're competitive like that)
> May be it's the effect of money that comes from selling products and not working under a boss.

I think it is more of an affirmation thing. It was for me first time I was paid for a product all those years ago. It was originally written (quite naively and so badly in many ways, but it worked!) because I needed it so it didn't have to make money: but when it did it felt very good because someone else thought that my work was worth paying a little for.
The screensaver mode can be disabled. The enumerating thing will most likely lead apps to crash, so I am quite sure no other app is doing this, so it's safe to ignore.

Display Arabic Digits, Dates in PDF & .NET Framework 4.0 Support
This new release includes better support of displaying Arabic digits, dates and punctuation inside PDF document and more stability with .NET Framework 4.0. Users can also add images stored in Unmanaged MemoryStream object. There has been a huge requirement of specifying different Background color information for different levels of Table of Contents and I am pleased to share that this requirement can be accomplished with this release. The product has become more viable to render em, Strong, Center and many other tags inside PDF document.
I'm not one to complain about UI changes, but I truly think they'll need to tweak this. In fact, it should be the reverse IMHO. Shift + enter= submit and enter= carriage return.
Although there were basic market dynamics in Frontier and First Encounters, I always felt it was too straightforward to fly between Sol and Barnard's Star selling robots without any risk.

Market forces in an Elite-themed MMO environment would make it such an enjoyable experience. One can imagination hunting around star systems affected by war, supplying them medicine (or even black market weapons!), having to compete with other players to get the best deal.

Do I upgrade my trade capacity to make more of a profit or do I install a laser bank to reduce the risk of making any? What will the other guy(s) do? Can I hire somebody to protect me who will take a share of the profit?

Infinitely more fun than the 'grind...grind...grind...' dynamic that plagues MMOs these days.

"The screensaver mode can be disabled" - the first app wants to enable the screen saver. The second app wants to disable it. What happens?

"will most likely lead apps to crash" - you're a developer who's attempting to hack somebody else's app so that yours stays on top. This is a regular topic on Raymond Chen's blog - the kind of developer who does this isn't normally worried about a bit of crashing.
I still prefer the tutorial on the homepage of mongodb.org. Click "Try it out" and type "tutorial". This is very well done too, though.
There's already no chain reaction - the control rods, plus the boron in the water they're pumping in absorb too many neutrons to sustain a reaction. The heat is not from uranium fission, but rather from the fission products made while the reactor was running undergoing spontaneous decay. This process cannot be stopped; you can only wait for it to slow down and cool to a reasonable level.

The reason they want to keep it cool is to prevent the fuel rods from melting. While melting won't immediately mean a release, it would mean the loss of two of the five barriers to a radioactive release, as well as quite a lot of heat for the remaining barriers. It would also significantly complicate later cleanup. As such, it is preferable that the fuel rods remain intact if at all possible, and this means attempting to cool them.

But I don't know how many Sieverts the map represents. Or if it's even depicting rate of dose over time.
For quite a few years now it seems like a lot of Unix-style software has gone beyond text streams, to include a back channel connection to external data and processes (databases, http services, etc).

I generally enjoy sharing context as a data structure with a file-system-like interface (e.g. REST) between processes, and only more so when the command/control interface is a simple text stream. Of course, this reminds me of Plan 9, but there's also 1060 Research, and other examples I'm sure.

There is quite a lot of head room left in the Plan 9 paradigm, and you do yourself no disservice by taking some time to figure it out. It really is more Unix than Unix.
I never wrote that hierarchy is the only way to organize data. Search and tagging are very important, too.

But where did you get the idea that hierarchies are useless?
By the point you're producing hydrogen, you're already well beyond your design limits...

Moreover, they've already lost primary, secondary, and tertiary power, so what exactly is going to run those ignition circuits? A gas flame near the reactor is just trading one source of explosion for another. And if they _did_ have power, they'd be running the primary (or secondary) coolant loops, and wouldn't have any hydrogen gas generation.
The typography is off. The body text is written in Arial, which is not a great choice for body text (it's better for display). When in doubt, use Verdana (sans-serif) or Georgia (serif) for body text. Also, the font size is too small.

Here is an example of his blog with better typography. I used 18px Georgia as the body text instead of 12px Arial. I used Droid Sans (a nice display font) for the blog title.

You mean like Eve Online? :-)

http://www.eveonline.com/

Actually, this response is directed towards shogunmike also. Just in case you haven't heard of Eve, it's a spaced themed MMO very much to the tune of Elite. You can make a living mining, trading, fighting. The factions are split onto two levels: Corporations (companies that employ/hire individual players) and Alliances (gropps of corporations with similar vision/goals)

The ecomony is almost entirely player driven.. the materials are mined by players, the equipment is built by players from those materials. You are free to engage in hostile activity even in controlled space, although the penalty is severe.

It's worth a look. The freedom of play has allowed some players to gain notoriety even in the mass media (Note: exchanging game money for real world currency is a violation of the rules):

Emacs is really more of a programming platform than a standard single-function application. It doesn't make sense to compare it to Unix apps like wc or ls. It's more similar to Bash, which allows you to combine built in functions and a whole host of separate programs (awk, sed etc).

Put another way, Emacs makes it easy to process text files, combining the built-in features and modes of Emacs with just about any Unix command-line tool (via M-x shell-command-on-region, or simply by processing the file from a terminal and passing the result back to Emacs). Word, on the other hand, makes it easy to do fancy word processing and associated formatting tasks inside Word, but makes it very difficult to share the resulting file with other programs (even different versions of Word).
Example / citation, please.

Pre-emptive counter-example: how would you compare PowerShell commandlet argument parsing to that of bash builtins?
Thats awesome.

Jersey Shore Season 3 Episode 12
post a "review my startup" on hacker news
Not a pleasant story, but true...

I used to work at a place where one of the guys wrote a horribly complicated piece of code that about half of the system depended on. He was also quite an unpleasant man who routinely mocked everyone else in the company for not being as clever as he was.

The company ran out of money and needed to halve its workforce - one of my friends overheard him boasting that there was no way that they could get rid of him, as no-one understood what he had written.

I was asked about his code - I said no-one but him could maintain it, but give me three months and I could rewrite it.

I don't like to revel in other's misfortunes but the look on his face as he left the office on the day of the redundancies was a picture.

In the end I kept half of his code (ring-fenced so it was effectively a black box that no-one touched) and rewrote the rest in about a month.

Personally, I work hard, make it visible (as Luyt says), own up to my failures and every now and then go beyond the call of duty. And I try very hard to be nice to people, even when they're acting like idiots.

You can sort them either way. :)
I think disabling takes precedence over enabling. This is to prevent interruption of e.g. a movie the user is watching. I can't think of a use case where the user would want a program to start the screensaver even though another app has disabled it?
I imagine this is why: http://upload.wikimedia.org/wikipedia/en/8/83/2008_US_electr...
[Edit; Okay, you're selling to tutors. You should make that even more blindingly obvious, and either make a separate section for people searching for tutors, or remove it altogether because the experience is crap. Are you sure adversising as free is legal? I mean you must be charging some mark up that the customer pays above what the tutor gets.]

Your first minute is useless. I go to your site and understand, okay, you're basically an online tutoring intermediary. But the services you offer are difficult to figure out, there's no categorisation or tagging, the search is bad, and you're not sure if your primary customers are the people buying or selling the service.

All in all, desperate.
'less' is actually an improved reimplementation of 'more'.

On my Mac, for example, 'less' and 'more‘ are hardlinked:

$ find /usr/bin -samefile /usr/bin/less
/usr/bin/less
/usr/bin/more

And invoking 'less' as 'more' most probably makes less drop into a compatibility mode.

Also, 'man more' brings you to the less(1) page, which contains the following snippet:

Less is a program similar to more (1), but which allows backward movement
in the file as well as forward movement. Also, less does not have to read
the entire input file before starting, so with large input files it starts
up faster than text editors like vi (1). Less uses termcap (or terminfo
on some systems), so it can run on a variety of terminals. There is even
limited support for hardcopy terminals. (On a hardcopy terminal, lines
which should be printed at the top of the screen are prefixed with a
caret.)
No, look at the real life constraints of the problem. The screensaver can be prevented from starting by using SetThreadExecutionState or moving the mouse. Another app can't stop you from making the system unidle.

And in the second part you're not paying attention to the constraints. If you want to simply kill all programs, that's easy in windows. The problem described above is to keep the system running, but become the topmost window. So a solution that causes crashes is not a solution.

Crashing a windows program is trivially easy, and it would "solve" the problem, but that's not the right kind of solution.

How much has been spent on nuclear energy in the way of resources, exactly? I'd like to see a citation here. And a comparison to spending on solar.

I note that you carefully ignored the issues of baseline power generation needs (e.g. the sun does not shine all the time) issues of power transmission from the middle of the ocean in your ocean proposal, the fact that putting solar in the ocean will significantly reduce the panel's useful life, and a host of other issues.

I'm quite prepared to believe I don't understand the science, but please don't pretend like you do. Handwaving serious problems away with "oh, if we just throw lots of money at them they'll disappear" is not "science".
Actually, it's present in both of them.
Great article, nice graphics. His other articles are very good too. I'd love to see someone explaining the details of memory management for the ARM Linux kernel with the same clarity.
I'm usually wary of anyone who argues that mouse and windowed GUI usage wastes precious time, because it tells me that this person prematurely optimizes, focusing on typing and screen navigation time when the idea-to-code bottleneck is actually the part where you THINK before you ACT.

The actual time spent hitting keys on the keyboard pales by comparison (or at least it should, unless you're producing unmaintainable code).
I think it's more of a message to Amazon that just streaming a few thousand movies won't be enough to steal the market from them. Amazon is great at breaking into new areas, but I think they would have to think twice about moving into television production, given that it's so far outside their sphere.

Alas, I still work with a program where someone had the bright idea to play tricks like this and, as a result, you can get error messages stuck completely behind an unmovable topmost window.

Thankfully, there's one slightly obscure way to get Windows to move a window that's completely behind another window, but many people don't realize there's anything back there in the first place.
Good question. A Microsoft Developer Evangelist emailed yesterday to say that they actually found it very funny. They've also had about six months to get in touch with me about the domain. Needless to say, they didn't.

"Pretty sophomoric, insignificant, and unworthy of HN readers' time."

I also agree with this assessment.

But please understand that I didn't do this to poke fun of Microsoft or anything like that. It was just funny at the time. I'd completely forgotten about it until yesterday morning when my inbox was suddenly flooded.

Now, I'll update in a week, after I leave, to see if I still feel the same way about it.
In such a case an IT admin remote controlling a PC, or an employee goofing off with Windows Player will prevent my app from gaining exclusivity. That does not solve the problem.

Also, exclusive access to the screen does not guarantee your program will go uninterrupted. Retaining exclusivity is impossible, because you just might get an ALT+TAB, CTRL+ALT+DEL or a WM_KILLFOCUS from who knows where. There are custom techniques for getting around each of those, but they're all along the lines of what's described in the article. Attaining and retaining exclusive access to the screen is next to impossible.
Sorry, I wasn't advocating berating the guy.

There is a need to send him one email, saying "Hey, noticed you made a mistake. It's pretty public (see hackernews), and you should fix it soon. Hope that helps!"

I hoped that someone would reply, saying, "Yup, I emailed him." and thus mitigate the potential flood of email. Since there was no announcement on the website to the tune of "Whoops, we made a security blunder, you'll have to do X to log in now", I assumed the guy was oblivious.

Why does everyone assume Ballmer defines product strategies at Microsoft? I'm pretty sure he defers to his direct reports for that. Whether thats a good or bad thing, I don't know.
I sorry, but what does he mean by "reintroducing into schools the kind of basic programming skills he learned".

He would have been a school in the 1970s, what school taught programming then and what on?

I don't believe that there was an actual computer class at any ordinary school in the UK at that time (outside of Eton or something) that'd teach you how to program.

Or have I got the wrong end of the stick?
