If price was the only concern, printrbot simple and junior would fly off the shelves. 3d printing seems like it will be important in how some things are made in the future, but anyone getting in now should do it out of interest, not utility

Gdb for g++ may be; msvc for c# is not! Gdb usability and performance is a (THE) major shortcoming of the gnu tool chain.

All that does is driving up home prices. 1600 sqft 4 bedrooms in cheap cities (san mateo, redwood city) are inching towards a million. If you want 2500 sqft in a walkable city with amenities, expect to pay closer to two million!

So, Broder had admitted to braking the law by going 85 to "keep up with traffic." That's the most bizarre omission here -- we don't get to pick and choose which laws we decide to follow!

You can mix and match x87 deterministically if you turn off 80 bit double internals. For SSE you need some SSE2 and 3 modes to do the same.

1) I don't want wireless at all. Too easily hacked without detection. Wired Ethernet is pretty cheap these days, and power line signaling is also available. 2) Like Twine, another HA startup, and all of the incumbents, it's too expensive.

Half high yield bond funds, half blue chip stock funds, bank all earnings, re-balance once a year, and take out 4% a year from total. On average you will do just fine! (Check against history if you want to verify)

The break is part of your working hours. And if you live an hour from work, research shows you will be much happier if you move to within 20 minutes (even if this means you get "less" for your money.) 6 hours without reddit, hacker news, me

I think the Cortex M4s that are coming out have 512 kB and up in their bigger variants. They also have more MHz and MIPS, and just need a cheap board available. The TI Stellaris Launchpad is looking good in this direction.

Exactly my reaction. You can run Python actually ON a Raspberry Pi, btw. That device is just not as robust on GPIO (5V destroys it, weak current source.)

The point of 401k is that you compound the growth on the deferred tax money, and then pay much less /present value/ tax once you retire. Index funds and high yield bond funds give you low overhead with almost no "gambling" element. Drawback

The fallacy of "A 32-core server is fast, and I can rent servers for 4 cents an hour, so I can rent a 32-core server for 4 cents" is unfortunaltely more common than I'd wish. If that simple error is in this analysis (and affects the cost an

Because good programmers are hard to find, and hardware companies sell more if they can convince EE design managers that their software is so easy, even the outsourced interns can be productive with it. Everything becomes crappy, because mo

You can buy a full Android 4.0 tablet for $35. It has Wifi, backlight, screen, CPU, battery and case. The BOM for this lamp is totally doable for a dozen dollars. It's productization that's the challenge. Sometimes, a smart scrappy start-up

It's because the market competes on features. This leads to a race to the bottom. If you go slower and test more, you will be too late and too expensive, and nobody will buy your stuff. The market does not value too high quality.

Energy is close to free. Peta-Watt-hours per day come into the earth from the sun. The problem, in the US, is that the median income in real dollars has actually declined in the last decade/s. This means the mass market has lower purchasing

It's also a "business competency" thing. Which, sadly, does not overlap very much with "technical competency" in many organizations.

This is why organizations should pay $1 per year for each IP address they own.

Most movies in history would be illegal, because most of them depict murders. Note that it being an /actual/ murder or abused child is not a requirement.

In the US (and Sweden) it's apparently illegal to possess /drawings/ of child porn. No child harm needed, only the potential for impure thoughts. Fundamentalists of any kind trying to impose thought crime is the real problem here. Fix that,

That is Doing It Wrong, which he'll see when he gets to scale. Real time chat needs real-time systems. Too bad gTalk, Facebook Chat, AIM or MSN Messenger aren't available on the market. The closest is ejabberd, which is nowhere near perfect

All the time! We use PHP, so each request is a blank slate -- persistent state is all in mysql, redis and memcached. DB schemas are pushed/applied before the code that uses them. Also if it wasn't clear: all those steps are automated, other

After all 40,000 unit tests have passed, sync that version to prod with ssh tunnel. Rsync to new directory on all target machines in a rsync tree. Switch to new version by moving a symlink. Verify new version by looking at metrics -- if som

I wonder if someone patented an actuator/microcontroller based cuff. The "key" would contain a battery and the cuff would challenge the key for the right password. There's lots of cryptography that could be used there, from shared secrets t

I've had some whoppers in Erlang, where "garbage generated" ends up costing N-squared, even though the operations were just N. In fact, the garbage collection footprint turns out to be one of the most significant markers for functional perf

The undertones created by the high overtones are realized in the anti-aliasing filter during recording. That's not actually the reason 44 kHz sampling isn't enough.

Nyquist is true for static signals. Music is not static. Brick wall at 20 kHz and get audible phasing artifacts! (Even if your filter is phase linear)
