Comment Re:This study is garbage (Score 1) 186

The study is actually important. They showed that the brains didn't recover from the damage as expected. The radiation treatment did not trigger the plastic repair behavior expected from an injured brain.

Yes, the particles used don't resemble background Solar radiation. It doesn't even resemble the stream of lightweight charged particles from a Coronal Mass ejection. However, the model is similar to the burst of Cosmic Background Radiation (CBR). Like the kind you get on an unplanned spacewalk to fix something on the outside of your spaceship. Or if your shielding fails.

It is very hard to make a usable spacesuit for a human that shields against individual sometimes neutral particles with the energy of a fastball thrown by a world record setting baseball pitcher. It is also hard to build a light enough and thick enough shield against CBR when your astronauts insist on hanging out on the edges of your rotating spacecraft to avoid losing bone mass.

This lack of repair response is the kind of thing you have to learn about to be a space faring species. It's the science part of science and engineering.

Fixing it is the engineering part. You'll have to use better shielding. Or you can genetically engineer people to trigger the plastic response to damage like Water Bears use. Or just make all repairs outside the CBR shielding involve robots and drones.

Is the problem of cheap blue LEDs News worthy? The conversation certainly is. News can inform but need not always be just current events, particularly on the Internet where nothing is paper.

Slashdot is a news aggregation site. Ostensibly for 'News for nerds, stuff that matters' at founding. In practice is was a blog for Rob Malda, CmdrTaco. It was also a website with an accidentally really good commenting technology.

Been around long enough to see the jokes about not reading the article? Then you have probably been around long enough to see the argument that a lot of the people still visiting the site do so for the conversation in the articles. They provide everything from group-think arguments, good counter-arguments and funny jokes about the topic to warnings about click-bait, pay-wall free options and corrected sources.

If Slashdot had ever depended upon the quality of the articles it would have failed when it was still Chips-n-Dips hosted on a university student account. The commenting system is more than a chance to keep up your HTML skillz. People in the know are really providing the value. (Queue complaints about Facebook's model, etc.) However, getting quality articles is important to attracting the readership that does not know about the site.

For instance, this article currently doesn't shows up in Google search for annoying LEDs, being a day old. But the top link is for for whatever reason. Stackechange and Amazon dominate the front page. I almost feel sorry for companies with products on that page. Even with no such thing as bad marketing, being known for having annoying lights on your non-party-joke product is not a good thing.

The Blue LED backlash article on McConnell's blog is page three. And he discusses a vendor that sells low intensity LEDs for computer products. But I expect - or at least hope - this slashdot article to make it to at least page three with McConnell's blog if not higher.

Does it work? No. But that depends on your definition of "work."

But Drug dogs work perfectly for law enforcement: they provide whatever answer the police want and the gullible public believe the dogs are infallible.

I fear you might not know just how accurate some critter's sense of smell is.

You might just not know how dogs behave.

If search dogs work then the dog should be fine to hunt these without the handler there at all. Just let the dog search on his or her own.

Search and rescue dogs work this way just fine every day. You let them go and they hunt down people easily that you or I cannot see or hear or smell.

But any person who raises and breeds and trains dogs professionally knows the first and only thing a well trained dog wants is to please the handler. That's the definition of well and trained for a dog. Drug sniffing dogs are very well trained.

In the hands of their handler a dog is just a dowsing rod for the man with the leash. Combine that with objects that conveniently fit in an officer's pocket and the long history of corrupt government officials. You shouldn't have plausible evidence. You should have plausible deniability. Yes, dogs are great at finding skunks or burnt joints you might be able to smell yourself. Not so much for things in air-tight closed containers on in piles of stuff that smells exactly like it.

But like you demonstrate, most people don't know how dogs behave. (Or how to spot magical thinking.)

Keep the handler away from the dog. Let it search on its own. Otherwise he or she is just a furry four-legged lie detector.

Is something like Debian itself Debian-based? Your answer to this philosophical question divides into two interesting camps of logic.

  • One is that a thing is most similar to itself therefore is always based on itself. The set of things similar to a thing would contain that thing.
  • The other is the idea that identity and similarity are completely separate concepts. The prototype in this latter thinking is not part of the set that classifies things into the set defined by the prototype.

It is not like asking what is the closest star to Earth (Sol, or the sun). It is more like asking what is the closest planet to the Earth. (Insert car analogy here.)

For sake of argument assume a planet is just something in the heavens that can be seen by naked eye and that moves daily against said heavens

All of this is without touching on important questions like is Debian made from Wood? Does it float? And does Debian weight as much as a duck? (No but only if you use rare double-sided, double-layer DVDs.)

When did the package manager become more important than the operating environment?

Documentation and support information tends to be organized around how each distribution works or fails. (Or just provided for Ubuntu.) Knowing the distribution of software involved is thus important for sending the correct links.

From good Linux questions the reader can figure out or be told:

  1. Which kernel won't load your graphics drivers (Linux, Android, ntoskernel, Darwin, BSD.)
  2. Userland so you know which switches don't work (BSD, GNU, busybox, something else.)
  3. Package Manager (yum, zypper, apt, dnf, up2date, app store, etc) so you know which software won't install.
  4. Filesystem hierarchy violations so you can't find where anything got installed.

The package manager provides a really good hint to everything in that stack. apg-get implies a Debian derivative, most likely Ubuntu. Use dnf? Probably a Fedora desktop user. Got a question that shows zypper commands? openSUSE or really recent SLES. Yum instructions? RHEL or older SLES. URPMI? Mageia Linux. up2date? Really really old RedHat. Brew? You want the Mac OS channel, this is ##linux. Someone handed you a tarball and 50 pages of ./configure, make, make install? Hello, the 20th century called and wants their unpackaged software back.

Knowing which package manager is involved can also be important for supporting users. Those users who a only familiar with very basic support for their specific distribution need to be given instructions exactly for that distribution. Telling someone to do 'sudo apt-get' a bunch of stuff on Fedora will just confuse them. You'll waste time explaining the explanation. Then you'll waste time explaining that after you get a wall of hate about how everything sucks, your instructions suck, your distribution sucks and why can't we have nice things?

More advanced users can translate between Slack, Arch recipes, .rpm local flavors , .deb or Gentoo instructions. They may package stuff for themselves or others. (Whether or not you have to eat a whole bucket of mushrooms to figure out how to make said package is another matter.)

These more advanced users also know that a particular package in some Google-able documentation may have a very different name for each distributions. Those who have been around longer know that some software is not even be available on the distribution with the issue to solve.

So, yes, knowing the package manager lets people know which Linux tribe you hail from and thus which kind of hate mail to send. I mean support to charge you for. After all, all operating systems suck.

Human factors and industrial engineering turns out to be important when working on systems used by humans.

I spent 15 years developing and writing password / pass phrase security tools used on a huge number of web site

This is the biggest argument for open source software. Security software is important software. It should work, do so correctly and be able to survive audit or exposure. Do you re-implement printf(3) to write a web page? (Usually no, but I've seen some interesting stuff. Ask a veteran C programmer to do HTML and you might get a new web server with the pages statically encoded in the binary.) But we re-implement user space stuff all the time that is really infrastructure in disguise.

The amount of time wasted re-writing stuff that should be written once and well is I guess a useful tax on the stupid. And too often that's how business works. The waste certainly keeps a lot of people employed.

"Code Monkey says maybe manager should write stupid login page himself."

In my professional opinion, where strength meters and password policies most often fail is that they greatly underestimate the importance of length. I recently encountered a site which required:

Requirements are funny things. Required fields on passwords actually reduce the strength of passwords. I don't need to guess or search the entire alphabet if I know that I only need combinations of unique characters. The result is a much smaller space to brute force. Sadly, without any requirements on variety most people just pick familiar and public information, which is even worse.

Comment Re:Driving yes, but charging? (Score 1) 990

Even with the American insane focus on the rush to get "there" the station doesn't make money off the gas. The profit is in the junk food, services and garbage for sale inside.

and it still won't be anywhere near as fast as refilling a liquid fuel tank.

And that is fine by this gas station logic.

There is money to be made in slowing down the pace of life. Just like making people queue a long time right next to the junk food stands at a Best Buy store. You might see restaurant style waiting tables inside more convenience stores with cellphone charging stations. Perhaps even possibly better bathroom cleaning schedules.

Well, one can hope about the cleaning schedules.

If you go places to do something longer than minute it fits with the EV lifestyle. This may sound like a retirement community approach instead of a high schooler's idealized speed-demon lifestyle. But the money is in gas stations that operate more like restaurants or rest stops. This is the reason charging stations pop up at malls, parks and recreational locations. Like a coffee shop with power for you in a cup and your car in a plug.

The real problem boils down to infrastructure.

For infrastructure we are only talking about the last few inch problem here. You already need a power tap to run the pumps. This just cuts out the pump between your car and the grid. Most of the remodel will be in getting those tables and chairs.

And getting those bathrooms cleaned.

If only that blackbaze pods were even remotely like other datacenter equipment. As far as vibration is concerned they are still pretty much a torture test for anything with a spinning motor. Minimal vibration protection while being mechanically coupled to a weak foundation while crammed in as tightly as geometry allows.

A temperature-controlled environment, clean power, low shock and vibration, and 1 out of 5 still fails

The density and structure of a pod is only temperature-controlled in that it is going to get hot, quickly.

Remind me never to buy Seagate.

The numbers from Backblaze you'll actually see that you shouldn't buy one particular desktop model of hard drive for your "datacenter." Numbers like Backblaze releases are quite fascinating in that you can analyze them. You can find which models at any vendor to prefer or avoid.

Oh, wait, I already vowed never to buy another Seagate- about 10 years ago after experiencing their unequaled propensity to die fast and hard.

Sorry to hear about your loss. I hope you kept backup copies. If not, I hope it taught you that if you don't have a copy then you don't have a backup.

It is certainly reasonable to avoid a vendor when a lot of their products from many lines have defects at a given time. Seagate's desktop line certainly took a hit from the initial Backblaze numbers. The DM1000's huge failure rate is almost as legendary as the IBM Death Star line or Maxtor click-of-death. But stuff from before or after a given run may have better or worse quality. And of course even manufactures can get batches of bad parts. (Hidden variables like that are one of the reasons why the singular of data isn't anecdote.)

I also wonder if we'll ever get numbers from Backblaze on things like the actual temperature, decibels and power these drives lived through. More than just avoiding a particular model. It would be nice to know how hot, loud and nasty you can get before your commodity-class storage starts pooping out.

I defy you to find a single person in a company who cannot comprehend something other than profit.


Also the implied definition of profit it very limited. There are other kinds of profit than 'make as much money as possible.' But the investors are always taking on some of the risk and responsibility for a profit.

Large investors like Venture Capitalists or Mutual Funds may only be interested in how to generate money since they don't really have any other value they can derive from a random business.

It is sad today that any company created who doesn't have the express purpose of making more money is called a non-profit. It reflects our current narrow thinking in Western culture and a lack of knowledge of our history. Originally a company was a kind of business that a group of people formed legally to achieve some end of some kind. There were many kinds of charters. Often expected social benefits were required for granting the recognition of a company as a thing.

A company was once practical tool for a practical world. If openness was not harmful it might even make the achievement of that goal easier by enabling other companies to work together to achieve that goal. A perfect example is Universities creating the Internet long before the private dial-up networks created their closed captive markets.

But in lassie-fare market economics secrecy can give your for-money-profit-only company a competitive edge. Deny others access to your market and force them to spend time developing their own trade secrets. There is little advantage in the for-money-profit-only world to you letting government regulators or customers in on your super secret formula. Best to do away with the FDA and BSA, too.Your product or process could be a ball full of crap, kill kittens to make pop-tarts or power ancient evil with pollution. Openness would be harmful to that business model.

The solution to this is very simple: end the H1-B visa program. Replace it with a program that lets you import a worker temporarily to do work only if (a) the employeer cannot find someone with the skills to do that job (b) willing-to-work-for-ramen level pay cannot be a consideration as a skill (c) that employee must actively train a native or green card holder in that skill. Set a deadline for replacing that worker with the native worker. Make the employeer pay both people at the same time.

When you are in business for the money that's the only thing you'll care about. Tariffs aren't just for products. Making that the H1-B "replacement" always costs much more than just hiring and training a citizen then your government is actively protecting and investing in the people that created that government to protect and invest in them. As long as your elected government creates and supports a system of cheap labor importation those employers who can take advantage of the cheap price will.
