Comment Re:BTRFS is getting there (Score 1) 169

and pre-load the database (most common way of getting data into the database initially) then hit it with an OLTP workload, ZFS will perform *terribly* - because it got large streaming writes up front, allocated huge stripe sizes, which makes rewrite performance go to hell in a handbasket,

L2ARC is supposed to fix this. I've heard good things about it.

My favorite nutjobs are those that are scared of HFCS. It's glucose bound to fructose. Your body processes it into... glucose and fructose.

You get into trouble when you take in too much of it, in the *exact* same way you'd get into trouble if you sat there and ate handfuls of cane sugar every day.

Just eat less of the stuff. A coke every now and then won't kill you.

Comment Penetration (Score 1) 308

To be fair, windows seems to have pretty good penetration into the embedded market already. Heck, I see random boxes with screens frozen on the windows desktop all the time.

My favorite experience is waiting at airport security a couple of years ago - there were screens denoting which lanes were open and which were closed. Apparently each screen was an individual windows box, and every single one would randomly crash and reboot every minute or two. Made for a nice light show while waiting mindlessly in line.

Comment Re:Open source ECM? (Score 1) 126

And you think it's hard to do better than the real guys, but they screw it up too, and they don't try particularly hard.

Remember, companies were throwing together working ECMs back in the eighties out of discrete components and one dinky microcontroller. Hitachi used a 3 MHz 6800-series chip in the computers that ran the Impreza, 240SX and some of its other contemporaries.

They do screw up sometimes, that's why there are years of testing done.

It's not the parts, or even necessarily the code. It's the process and experience. You need something that works reliably with precision AND accuracy for the life of the engine (ideally more than ten years) under every possible condition.

wrong way around.

His idea:
Fructose is causing metabolic syndrome and partly responsible for weight gain by sabotaging leptin response.

Right - that's his idea. Hasn't been proven by any studies, though.

There was one study that showed some correlation but, IIRC, it was poorly done and not replicable.

For several years the anti-fructose movement has been making noise and has been showing increasing insight is the underlying mechanisms. Famous example spokesperson of this movement is Dr Lustig, and googling his name alone gives a boatload of references.

Comment Re:"Austerity." You keep using that word. (Score 3, Insightful) 85

Oldest trick in the book.

1. Cut library funding out of the general budget
2. Close the libraries saying that they are out of money
3. Run a special millage for the libraries

So your 'library millage' is actually a general fund millage that's been shifted around.

It works for a while - it's been done so many times in the city I live in now that the libraries are completely funded by millage.

Agreed. Not a huge fan of welfare in general, but this system is much preferred to the current system. Here's how you pay for it (remember this includes outlays AND overhead - overhead can be quite huge in some cases)

1. Eliminate all low-income welfare programs - there are a TON of these
2. Eliminate social security
3. You can probably eliminate most forms of medicare and medicaid
4. Eliminate most low-income student support programs (school lunches, etc...)
5. Eliminate most V.A. support programs, which is basically welfare as well
6. Government pensioners can probably have their pension payments removed from the minimum income (IE you don't get a pension AND basic income)
        - This won't necessarily save money but can ease pressure in the pension system
7. Eliminate make-work/stimulus programs

That's just the tip of the iceberg. You can probably eliminate unemployment insurance, minimum wage, heck almost all labor regulations as the philosophy behind them is that low-income workers are exploited as they are being "forced" to work to survive.

The corollary to this argument is - if you are looking at creating an algorithm to do something, odds are someone smarter than you has already done it better than your version and has put it on the internet.

This doesn't mean you shouldn't research what they did and have a firm grasp on how it works.

I've yet to have a programming job that only required you to be an expert in one domain. My last job had me doing statistical analysis on audio, environmental testing, figuring out satellite ephemeral products, reporting, some light DBA, and interfacing with various low-level and high-level buses, amongst other things. Almost none of that stuff was covered in my CS classes. There wasn't a book for a lot of it, either. I usually learned from looking up other people's code online.
