Ask Slashdot: Can You Say Something Nice About Systemd?

Carewolf Re:Speed (464 comments)

And that matters to a server how? I reboot my linux servers as little as absolutely necessary (security updates, kernel patches, etc). The added overhead and complexity of debugging why there was a problem with systemd (and its infuriating lack of text logs I can work with in any number of tools) is not worth 2 minutes of saved time every 3-6 months.

The binary logs are optional. I haven't used them, why would I?

Ask Slashdot: Can You Say Something Nice About Systemd?

Carewolf Re:Speed (464 comments)

I've killed systemd shutdowns hard after 15 minutes of timing out waiting for an nfs share that went offline.

The old system didn't do that. Not to detract from the lovely startup times, but it's not "all baked" yet.

I am pretty sure that would happen under sysv as well, though the old script might have had a workaround for the issue. NFS lockup issues is kernel "bug", the kernel refuses to shutdown or stop any requests that could lead to data loss, but if the NFS server is unreachable, that is impossible to avoid, so they just hang. This leaves to processes that can't even be killed with -9.

Sometimes risk aversity in a kernel developer is worth beating them with a bat over.

Ask Slashdot: Can You Say Something Nice About Systemd?

Carewolf Re:Thanks for making my point (464 comments)

I worked on space rated instruments at NASA Goddard for a while, and talked to a very old dude who claims to have seen this happen once in his very long career.

It happens about 40 times a day on you average PC, it is just rare it hits anything vital. If you run ECC memory you can track how many read errors it corrects. In fact error-correcting memory exists for servers and workstations for this very purpose. It is real and common.

Carewolf Speed (464 comments)

Just installing systemd over sysv speed booting up from a minute to 10 seconds, and shutting down from half a minute to under one second. I always hated Linux couldn't handle shutting the fuck down efficiently, now it does.

Denmark Plans To Be Coal-Free In 10 Years

Carewolf Re:I don't know what they are doing to burn coal n (226 comments)

Also note, very few people in Denmark uses electric heating as you can get hot water from centralized production into your home (not clean only for use in radiators). My parents gets their heating from a power plant 20km away.

Not to nitpick, but danes refer to that centralized production as "surplus heat". The "surplus" heat is heat generated as a bi-effect from producing electricity.... - from coal. So, when the electricity all comes from wind, the danes need to find some other way to heat their houses during winter.

It also comes from trash burning, but yes. There are issues to be solved for sure.

Denmark Plans To Be Coal-Free In 10 Years

Carewolf Re:circular politics (226 comments)

The Danes are probably looking to Sweden who has been doing this for years. Though in Sweden it only works because they buy coal-fueled power from Denmark during the peak hours.

Not sure who is planning this nonsense in Denmark now. We already have 33% wind power, but due to the issues with peak-power it will be hard to get above 66% and even that will require massive extra capacity.

Rite Aid and CVS Block Apple Pay and Google Wallet

Carewolf Re:Good luck with that. (554 comments)

3)Debit cards do not earn you interest. If you have an interest checking account (rare, and usually such a low rate that its a joke, sub 1% in most cases), you earn that money regardless of if you have or use a debit card.

5)Emergencies/hard times. Sometimes shit happens. You may lose your job and run low on cash. You may have a series of car and house repairs. Its always a good idea to have an additional emergency fun you can call on for short term cash.

That is why you have credit lines and always keep your account around zero or below. The interest on my debit card is 7% for minus or effectivly 0% for plus. Banks are always willing to give you a credit or one or two months full salary if you show them your job contract. That is often better or similar to most credit cards, except the standard interest is much lower, and if you negotiate with your bank you can get even lower interest OR higher credit.

Credit cards are never a good idea, and only makes sense if you live in a country where they are required. Which means the US.

High Speed Evolution

Carewolf Re:Is that unreasonable? (282 comments)

Probably just an urban legend. They were growing steadily before then, and aren;t that far off the Danes, Swedes, Austrians and French.

The men are not that far of from Scandinavians, but the women are. That is the main difference in the average heights, the Dutch women from that generation is as tall as the men.

Btw. A good counter point to the original talk about genetics is ancient Scandinavians. The Vikings were almost as tall as modern Scandinavians, it wasn't until a feudal society was created that the lower peasents class became as short as other places in northern Europe.

High Speed Evolution

Carewolf Re:Is that unreasonable? (282 comments)

The analogy really sucks.

It's very hard to find a photo of Abe Lincoln where he isn't at least a head (including his beard) above everyone else. But today several countries have an average height within a 10 cm of him. The Dutch are 184 cm (about 6' 1"), but Abe was only 193 cm (just under 6' 4"). Partly that's due to nutrition, which has an incredibly complicated relationship to height (the Dutch, for example, are dragged down by the descendents of people born during a famine after WW2. Their grandchildren are unexpectedly short and nobody knows why.).

A Dutch person told me an odd tale about hormones they allowed or put in the food during the 70/80s that led to a single extra tall generation. They got rid of the hormones later and hushed the whole thing up, so now the next generation is back to normal height.

Not sure I believe it though, never found anything to back it up, so it could just be a dutch urban legend.

Employers Worried About Critical Thinking Skills

Carewolf Re:What is critical thinking? (553 comments)

IMO, the fact that the establishment is the establishment should be reason enough to subject them to constant questioning and criticism. Nobody in authority should be able to do so much as fart on the job being expected to justify their actions -- in front of a jury if necessary.

Yeah, that kind of logic is what anti-science thrives on.

Apple Doesn't Design For Yesterday

Carewolf Nonsense (370 comments)

The distortion is strong in that one. And now he must excuse his earlier brief glimses of reality.

Btw. Helvetica is a classic font that is more narrow and easier to read than Lucida especially on print, on a screen it is best with good hinting, which Apple's fontsystem doesn't do.

iFixit Tears Apart Apple's Shiny New Retina iMac

Carewolf Re:iMac? (109 comments)

Yeah, I'm wondering if they're going straight for 3D gesture and voice control type stuff.

They've already got the mind control covered.

It just too bad they made it work the wrong way. I would prefer a machine I could control, and not the other way around.

Yeah, but how do you get 200+ people there for the party, without the cost going up?

Experts Decry Randomized Ebola Treatment Trials As Unethical, Impractical

Carewolf Re:Our PC society will be our demise! (193 comments)

the news increasingly censors any opinion that would be against socialism or popular accepted opinions

I find it incredible that in the 21st century Internet-connected Scandinavia, there are no independent contrarian news outlets.

There are. Don't conflate Sweden with the rest of Scandinavia, and even if Sweden there are contrarian outlets, it is just that most Swedes pretend opions they don't like don't exits.

Genes Don't Just Predict Intelligence, But Also How Well You Do In School

Carewolf Re:Yet "intelligence" genes have little effect (154 comments)

Yeah. And as I remember the twin tests from a decade ago, they did show genetics played a large role in how well the kids did in early school, but by the time they twins were 18, the environment was a much bigger factor. In other words the article here has it backwards. Genes doesn't predict intelligence in adults very well, upbringing does, but what genes do predict is how easy a time you will have in early school, which may help you if you have bad school. However, if you don't have an easy time early in school, know that, by the time you are out of school and university, the genes doesn't matter as much as how hard you worked (and how good schools/parents you got).

Bugzilla Bug Exposes Zero-Day Bugs

Carewolf Headline does not match subject (34 comments)

So you can register an account with an email from another domain? Still I know of no-bugzilla where security bugs are allowed to be seen by everybody from a certain domain. They are allowed to be seen by certain number of emails, and since they are already registered, you can't create a new account with one of those.

So, not really that much of an issue unless you have really wide permission to everybody from specific email domains.

The Wayland Situation: Facts About X vs. Wayland

Carewolf Carewolf writes  |  about a year ago

Carewolf (581105) writes "With the continued speculation and FUD about the future of Wayland at a time when Canonical is investing heavily into their own Mir Display Server alternative, Eric Griffith with input from Daniel Stone have written an article for Phoronix where they lay out all the facts. The "Wayland Situation" is explained with first going over the failings of X, the fixings of Wayland, common misconceptions about X and Wayland, and then a few other advantages to Wayland. For anyone interested in X/Wayland or the Linux desktop at a technical level, it's an article certainly worth reading!"

Too Perfect a Mirror

Carewolf Carewolf writes  |  about a year and a half ago

Carewolf (581105) writes "Jeff Mitchell writes on his blog about what almost became "The Great KDE Disaster Of 2013". It all started as simple update of the root git server and ended up with a corrupt git repository automatically mirrored to every mirror and deleting every copy of most KDE repositories. It ends by discussing what the problem is with git --mirror and how you can avoid similar problems in the future."

Vulcanic Ash Grounds North Europe

Carewolf Carewolf writes  |  more than 4 years ago

Carewolf (581105) writes "In an interesting story of weather and techonology. After a vulcanic eruption in Iceland. All flights in and out the UK, Denmark, Norway and Sweden have been suspended. Finland and Belgian is also shutting down airtravel, and the ash cloud is expected to affect airtravel in all of North Europe during the day. The reason the vulcanic ash grounds the planes is due to leasons learned from KLM Flight 867 in 1989, and British Airway Flight 9 in 1982, where vulcanic ash in both cases sandblasted front windscreen and shut down all four engines."
