How 'DevOps' Is Killing the Developer

Chirs not all coding requires databases (136 comments)

I worked for over a decade in embedded stuff, mostly Linux kernel development. I didn't do a smidge of database coding the whole time. It just wasn't a factor. On the other hand, I did learn assembly language for five different architectures, found locking bugs in glibc, binary-patched the running kernel for a production fix because the client didn't want to take a new release, and a bunch of other interesting stuff.

And now I'm working on a different project that uses databases heavily, so I'm picking it up as I go.

The New 'One Microsoft' Is Finally Poised For the Future

Chirs just need to do your due diligence (270 comments)

You can "interact with" GPL code just fine, as long as your proprietary code isn't a derivative work of the GPL code in the copyright sense.

So you can exec() it, you can call it from the shell, you can send packets to it and receive responses, in some cases you can even have proprietary code as a module/plugin being called by the GPL'd code.

Canada Introduces Privacy Reforms That Encourage Warrantless Disclosure of Info

Chirs "fair" is a rating, not a description (99 comments)

So under the new Act they'd be "fair", as opposed to "good" or "very good", or "excellent". :)

Theo De Raadt's Small Rant On OpenSSL

Chirs that's pretty standard (301 comments)

Major numbers are often reserved for things that break backwards compatibility, minor numbers often denote new features, and the patch revision denotes patches.

Personally I would have bumped the patch rev (the third number).

Land Rover Demos "Transparent Hood"

Chirs Brilliant. Now for proximity sensors. (172 comments)

I'd also love to have proximity sensors giving the distance from any part of my car to any obstacle. It'd make parallel parking a lot quicker if I could get a readout showing how many inches there are between my car and the vehicle behind me.

Rearview cameras can be useful, but unless you've got one like an RV mounted way up high aiming down at the back of the vehicle they won't help much in parking.

Should Microsoft Be Required To Extend Support For Windows XP?

Chirs why should she be forced to upgrade? (645 comments)

Your mom likely has no excuse not to upgrade.

The question is not "does she have an excuse not to upgrade". The question is, "why should she be forced to upgrade"? If the computer that she has is meeting her needs, why should she need to pay to replace it or have it upgraded?

A fifth of the light trucks made by both Toyota and Chevy are still on the road after 21 years. The manufacturers don't necessarily support them, but other companies do. Why can't we think about software in those terms?

An SSD for Your Current Computer May Save the Cost of a New One (Video)

Chirs I run 16GB in my laptop and I'd like 32GB (353 comments)

But then I do OpenStack development.

Spinning up VMs on qemu via OpenStack running on Virtualbox instances. Whee!

An SSD for Your Current Computer May Save the Cost of a New One (Video)

Chirs doesn't have to be that bad (353 comments)

Theoretically the disk controller could initially access only the spinning platter, and then only the frequently-accessed blocks (reads or writes) would get relocated to the flash drive.

Details You're Not Supposed To See From Boston U's Patent Settlements

Chirs I have no problem with patents as intended (130 comments)

If I come up with a way of doing something, I don't have a problem with you needing to either re-invent it from scratch or else pay me to use my idea.

I do think that if you can show that you really did invent something from scratch *without ever seeing my invention or hearing about it* then you shouldn't have to pay me.

Similarly, a patent should be on a specific implementation, not a general concept. This latter part seems to be a huge problem with many software patents...they try to patent a concept rather than a specific implementation of the concept.

Details You're Not Supposed To See From Boston U's Patent Settlements

Chirs you would be wrong (130 comments)

I always thought you could "make your own" from patent filings, you just couldn't sell/trade/traffic/commercialize it.

Nope. Per Wikipedia, "...a patent provides the right to exclude others from making, using, selling, offering for sale, or importing the patented invention...".

Now usually it's not worth the time/effort to enforce patents against end-users since they generally don't have much money. But witness the patent trolls going after small businesses for "scanning to email" or the use of wi-fi (really, look up Innovatio IP Ventures).

The Connected Home's Battle of the Bulbs

Chirs not as good as the old Philips L-prize bulbs (176 comments)

I like the Cree bulbs. I just wish they (or any other) were as good as the Philips L-Prize bulbs (93 CRI and 93 Lumens/W)

For comparison:
Cree TW series: 93CRI and 59 Lumens/W
Cree regular: 80CRI and 84 Lumens/W
Philips: 81CRI and 72 Lumens/W

Supreme Court Skeptical of Computer-Based Patents

Chirs more than that... (192 comments)

It seems to be common in software patents to try and claim not just a method of doing X, but the whole *concept* of doing X.

So for instance, the *concept* of doing rubber-band bounce-back. Apple has a patent on this. (http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=7479949.PN.&OS=PN/7479949&RS=PN/7479949)

To me this smacks of patenting an idea, rather than a specific way of implementing an idea.

Linux 3.14 Kernel Released

Chirs it can be more efficient for some (132 comments)

Sure, it may not make sense for everyone, but I bet there are cases that will see significant gains.

For example, imagine you're running a server with too much data to fit in RAM uncompressed but a lot more (maybe all of it) will fit in RAM if you compress it. So by doing compressed swap, you spend a bit of CPU power (to do the compression/decompression) to avoid a lot of waiting on I/O.

Sure, if you put in a bunch more RAM you could fit it all, but that might require buying new hardware, or maybe you've already hit the limit of what's available and still want more performance.

An Engineer's Eureka Moment With a GM Flaw

Chirs not so simple (357 comments)

The fact that GM didn't change part numbers would certainly make it harder to figure out what was going on, because there would be no indication of problems in current vehicles.

Had the part number changed it would have been an obvious thing to check--what's different between the old part and the new one?

An Engineer's Eureka Moment With a GM Flaw

Chirs profit at the expense of safety (357 comments)

I wouldn't say that what they did was "evil", but it does smack of trying for profit at the expense of their customers' safety. And public perception is important...this is why Toyota got into so much hot water over their throttle issue--they were perceived to be a very safe vehicle so it was a shock to discover that they were hiding safety issues.

What GM should have done was to change the part number and notify the owners of vehicles with the old ignition switch to come in to a dealer to get them swapped out for a good one.

Look at Tesla...very good safety record but they're raising the ride height a bit and adding a titanium shield just to improve the safety that much more.

An Engineer's Eureka Moment With a GM Flaw

Chirs it's not that GM wasn't saying what changed (357 comments)

It's that GM didn't actually admit that anything *had* changed (the part number was the same), so he had no reason to suspect that there had been a change in the ignition switch.

An Engineer's Eureka Moment With a GM Flaw

Chirs no, a change means a different number (357 comments)

Even if you don't *think* there is a functional change, any change in the part should result in a different part number. The computer databases will all have part number equivalencies in them, so anyone looking for the old part number will get redirected to the new part.

In that way, if a problem shows up later (like in this case) it's much simpler to determine that a part was changed.

Companies did the same thing in other industries. One of the Linksys 10/100 ethernet NICs (lne100tx maybe) had about 4 different ethernet controllers over time but kept the same part number. They needed totally different drivers under Linux.

skydiver to attemp record jump from 131,000 feet

Chirs Chirs writes  |  more than 5 years ago

Chirs (87576) writes "Former 64-yr old french paratrooper Michel Fournier is attempting to break multiple world records by jumping out of a helium balloon at 40 kilometers (131,000 feet) altitude. They anticipate that he will break the sound barrier on the way down, taking 15 minutes to fall and reaching speed of over 1500km/hr.

The big concern at the moment is the wind. Anything over 10km/hr will cause problems getting the massive balloon inflated. The previous attempt failed when the baloon was destroyed by wind while still on the ground.
