Torvalds: No Opinion On Systemd

putaro Re:Simple set of pipelined utilties! (333 comments)

Untrue. I've had the X server hang up and I've logged in via the network and killed it and restarted it. I can't restart systemd without restarting the whole system. Furthermore, I don't run the X server on our mission critical machines.

Why Apple Should Open-Source Swift -- But Won't

putaro Re:Your post is a non-sequitur. (179 comments)

The point being that Apple didn't adopt Objective-C just to be weird. Next used Objective-C to build NextStep and there's certain things in Objective-C that made NextStep moderately cool.

I actually worked at Apple, on the operating systems team, around that time. Apple was in no position to be arrogant in 1997 and wasn't actively looking for ways to be incompatible. Today, that's a very different story.

Should police have cameras recording their work at all times?

putaro Re:"Accidentally" (455 comments)

When a police officer is around you, you are being surveilled - by the police officer. If you're doing anything illegal in front of the police, expect to get in trouble. Police wear uniforms and are easy to spot. That's very different from having concealed cameras everywhere.

Project Zero Exploits 'Unexploitable' Glibc Bug

putaro pkexec?? (98 comments)

Sorry, old Unix guy here. My first reaction was "What the F is pkexec and why is it running setuid?"

Yet another way to execute arbitrary privileged executables is yet another potential security hole. This dumb thing is apparently part of the "Free Desktop" but it's depended on by all kinds of stuff including the fricking RedHat power management. What's wrong with plain old sudo?

If Java Wasn't Cool 10 Years Ago, What About Now?

putaro Re:What's the point? (511 comments)

The question is, who is "you" and when does that checking happen? I don't do a lot of work in Python, Ruby, etc. and all of the programmers that I know who do are fairly young and working on fairly small projects so they don't have a good answer for refactoring.

If I change the arguments to a method in a statically type language any place where I forgot to change the call to that method will be exposed at compile time. As far as I've been able to learn so far, in most dynamically typed languages that check won't happen until runtime. The pat answer to that is "you should have unit tests that cover everything" - but getting complete code coverage is hard and for large projects, the test suite takes a non-trivial amount of time to run - usually much, much longer than compile time. So, you wind up with bugs at runtime. Or is there a better solution?

Major Delays, Revamped Beta For Credit-Card Consolidating Gadget Coin

putaro Problems getting merchants to accept it? (78 comments)

Technically, I see how it works but why would a merchant accept this thing? It doesn't look like a credit card and it's missing all of the anti-fraud elements built into the physical cards. According to their FAQ, Coin is trying to substitute an image on your smart phone plus their gadget for your physical card but I don't see that any of the actual credit card issuers are actually endorsing this. As a merchant you might be in violation of your merchant agreement by accepting this thing.

Facebook Experimenting With Blu-ray As a Storage Medium

putaro Re:Why not just use hard drives and then store... (193 comments)

The Blu-ray disc needs to be mounted before it can be accessed. The ratio of robotic mechanisms to discs becomes important. If you need to mount ten discs, it takes ten times as long (if they're all using the same arm) whereas you could spin up ten hard drives simultaneously.

I've worked with large scale robotics since the late 80's. The performance of the arms has not increased significantly since then. When you're dealing with scientific datasets or backups it's not as much of a problem. In random access storage, though, it starts to be an issue.

How Does Tesla Build a Supercharger Charging Site?

putaro Re:And how long does it take... (190 comments)

Also, as they proliferate, they're going to have to deal with vandalism. A gas station is a neatly concentrated resource with oversight, security and even they still get vandalized.

Don't whiz on the electric fence!

Things like pricing can always be messed with. I think the maintenance issue, as the network grows, will become challenging. We'll see, though.

How Does Tesla Build a Supercharger Charging Site?

putaro Re:Enough of the Tesla circle jerk (190 comments)

And in 1900 the same arguments applied against gasoline cars and you could get food for your horse, have a stable to keep it in, find a blacksmith to put new shoes on your horse, etc. just about anywhere.

The technology for EVs is still pretty early and just starting to improve. Give it another 10 years and it will probably address most of your concerns.

Operating Systems Still Matter In a Containerized World

Operating Systems Still Matter In a Containerized World

It's kind of silly but no worse than network file systems. And, containers don't have that virtualization overhead.

Ask Slashdot: Would You Pay For Websites Without Trolls?

putaro Why would a paywall keep trolls out? (382 comments)

It might keep a few out but there are people who get their jollies out of trolling and the outrage that they create and might be willing to pay a few bucks for their hobby. It's been going on at least since Usenet (mid 80's).

I do enjoy small scale discussion on Facebook. I usually limit people who can post on my comments to friends of friends and that keeps the discussions more civil and usually more relevant. Perhaps the real problem is just that the number of people who can post a comment on many discussions is just too large. There is the risk of living in an echo chamber, though. Maybe a discussion site that creates groups with a representative sample of views, etc.

Companies That Don't Understand Engineers Don't Respect Engineers

putaro Re:Those aren't business decisions (371 comments)

They get an unlimited bonus structure so that there's no limit to how much they will sell. Sales people are greedy bastards and they will follow the money trail management creates, regardless of whether it is good or bad for the company. Structuring the sales compensation is very important - I've seen many instances where the salespeople are doing things that are not good for the company but maximize their payoffs.

Why do sales people wind up in charge? Because they sell everyone else on how wonderful they are. If you don't have a management team with some real knowledge of the business you will wind up with self-promoters running everything.

See, if you were smarter you would talk more and work less and get paid more (I've been telling myself this for years. I think my line of bullshit is finally getting to corporate grade).

"not even worth mentioning"

Bastards. Idiots with spreadsheets pretending to be engineers. Who would need a repair kit for a shuttle? No, that foam strike is no problem at all. Nosiree. Trust me

OK, who was the retard who decided to map entire PARTITIONS into memory and that therefore PARTITIONS (not files, file systems!) could only be a max of 2GB under HURD? Oy vey. Yah, you betcha GNU's not Unix. Maybe some SCO code would help.

putaro putaro writes  |  more than 11 years ago

So I thought I'd try installing GNU Hurd and messing with it. "Try the Debian CD image" beckons the GNU Hurd page. My, that's nice I thought. Who needs to read the instructions page - that's what the installer is for, right? Why bother making an installer if it's not going to at least install the boot loader? And then I'm supposed to type this at the GRUB prompt:

grub> module (hd0,0)/hurd/ext2fs.static \ --multiboot-command-line=${kernel-command-line} \ --host-priv-port=${host-port} \ --device-master-port=${device-port} \ --exec-server-task=${exec-task} -T typed ${root} \ $(task-create) $(task-resume)

Ya know, I don't mind doing the extra work since it's a development system - but why go to the effort of making a CD image and an installer and not do the last two fricking steps? A kernel comment comes to mind: This was hard to write, it should be hard to understand.
