Comment $1000, not $300 (Score 1) 43

Their presentation for investors quotes a sale price of $1000, not $300. At that price they might be able to do it. How well they'll do it remains to be seen.

Their presentation is all about their XY positioning mechanism. But that's not the problem. The hard problem is dispensing solder paste reliably and precisely, sticking the component down, and using hot air to solder it into place. As with low-end 3D printers, most of the problems are where the weld/soldering action takes place. They don't say much about how that's done.

The important thing is doing a consistently good soldering job. Nobody needs a machine that produces lots of reject boards.

Comment Should I do an ad blocker? (Score 3, Interesting) 436

I'm behind Ad Limiter, which limits Google search ads to one per page, picking the best one based on SiteTruth ratings. You can set it for zero search ads if you like. It also puts SiteTruth ratings on Google search results. It's a demo for SiteTruth search spam filtering.

This Mozilla/Chrome add on has a general ad-blocking mechanism inside. Unlike most ad blockers, it's not based on regular expressions looking for specific HTML. It finds URLs known to lead to ads, works outward through the DOM to find the ad boundary, then deletes the ad. So it's relatively insensitive to changes in ad code, and doesn't require much maintenance. The same code processes search results from Google, Bing, Yahoo, Bleeko, DuckDuckGo, and Infoseek. (Coming soon, Yandex support, and better handling of Google ads within ads, where an ad has multiple links.)

So, if I wanted to do a better ad blocker, I could do so easily. Should I? Is another one really needed? Are the headaches of running one worth it?

Comment Cell and battery production in same plant (Score 5, Informative) 95

The Tesla/Panasonic plan gets cell and battery production back into the same plant. The battery industry has, for a while, had a model where cells were made in one country (usually Japan, Taiwan or S. Korea, or at least with machinery from there) and assembled into device-specific battery packs near where the end device was produced (usually China or the US.) For the Chevy Volt, the cells come frm LG Chem in Korea, and the battery packs are assembled at the Brownstown, MI Battery Assembly plant.

There's no good reason to do it that way now that the era of cheap labor in China is over. As a rule of thumb, labor has to be 4x cheaper to justify offshoring. The coastal provinces in China have reached that level with respect to US/Japan wages.

Done right, this isn't labor-intensive. Brownstown has only 100 workers in a 400,000 square foot plant, and they're doing battery assembly, which is the more labor-intensive part of the operation. Tesla claims to need 6,500 employees for their 10 million square foot plant, but they're probably counting construction-phase employees.

Comment No new tools. Low-budget operation (Score 3, Informative) 67

All they're offering are some existing tools, ones you can get for free. The main ones are the Clang static analyzer and Cppcheck. They're not offering free access to some of the better, and expensive, commercial tools.

Cppcheck is basically a list of common errors, expressed as rules with regular expressions. Clang is a little more advanced, but it's still looking for a short list of local bugs. Neither will detect all, or even most, buffer overflows. They'll detect the use of "strcpy", but not a wrong size to "strncpy".

Comment The scammer's dream. (Score 3, Insightful) 172

Over half the Bitcoin exchanges have gone bust. Entire Bitcoin "stock exchanges" disappeared with the money. Bitcoin "investments" promising substantial returns each month were, of course, Ponzi schemes.

Bitcoin is a scam magnet. Irrevocable, remote, anonymous money transfers are the scammer's dream. (Yes, there are people talking about cryptographic escrow schemes so you can buy something with Bitcoins and have some recourse if it doesn't show up. So far, that hasn't reached usability.)

That's why Bitcoin needs regulation. If you're going to hold other people's money, you have to be regulated. Deal with it.

Utter crap. Codenomicon are very friendly to FLOSS and FLOSS developers. They're also great guys. They have been providing free test services to the Samba project for many years now, and have helped us fix many many bugs.

In case you hadn't noticed, the code they're reporting on here is closed source proprietary code...

Comment Each server is worth $189 or less. (Score 1) 208

If you want more servers like that, Wierd Stuff Warehouse in Sunnyvale, CA, has the same HP series G Xeon servers for $189. (2 3GHz quad-core Xeons per server! Hard drives are extra, but cheap.) Wierd Stuff has huge supplies of previous-generation data center equipment.

It's amazing how cheap computer hardware is now.

Comment Space travel isn't feasible. (Score 3, Interesting) 114

Reality check: space travel with chemical fuels just barely works. It takes huge rockets to launch dinky payloads, and that hasn't improved in 45 years. Satellites and probes are useful. Man in space has just been a boondoggle.

If fusion ever works, this may change, but with chemical rockets, it's not getting much better.
