This brings back some memories. When I was a young trainee engineer back in the mid 80's I worked at a Data General (DG) broker/repair shop.

One common job we did was refurbishment of DG Phoenix and Gemini drives. We sometimes had Diablo's, which is the drive make in the Alto video (possibly a model 30) and Zebra units (these were monster multi-platter units).

The ones I worked on were the Phoenix and Gemini drives (models 6045 and 6050) and were known as 5+5's (MB's) and 10+10's (MB's) meaning that they had a fixed platter, usually carrying the OS and you could top-load a single platter cartridge. There's quite a good picture here with one of these drives in the drawer out position :

https://en.wikipedia.org/wiki/File:Data_General_NOVA_System....

There was a plastic lid you'd put on top of the cartridge which is why you can't see the cartridge release handle in that picture. Normally you wouldn't be able to spin up the disk unless the chassis was pushed back into the rack, however the spring loaded "drawer open" sensor switch could be pulled back a notch towards the rear of the rack so that you could start the drive for service/repair work.

We used to do head replacements, re-alignments and fix head crashes. As was mentioned in the video, so that you could ensure that a cartridge could be reliably used across different disk drives you had a special disk that contained servo tracks which you would align the heads with. I think there were two, possibly three servo tracks on this disk (my memory is a bit vague). There were test points on the electronics you'd hook a scope up to so that you could check the alignment - there would be various pot tweaking to get things just right. Once you thought you had things "just so" the next step was to run the exerciser tests from DTOS (Diagnostic Tape Operating System - yes we booted the diags from tape) or ADES (Advanced Diagnostic Executive System). The Gemini and drives also had these huge linear motors that when in full test mode (seek tests in particular) were quite scary things to behold. This video gives you sort of an idea:

https://www.youtube.com/watch?v=qZsHTWiI0-4

We used to do regular trips from Scotland to London with a pair of Phoenix or Geminis in the company Sierra estate (1st generation). These things were so heavy that you really had to think about your braking distance once up to speed :) That poor car eventually had to have its chassis around the tailgate re-enforced after a few years of battering up and down the motorway with all that big kit in the back. Fun times though.
Off topic but why do you like those enough to pay $30? They're horrible at noise reduction (for you and those around you) and have shit for low frequencies. You can get a much better pair from Sony at that price . Always curious why people use them
I agree with the thrust of your comment, I'm not arguing that maths isn't worthwhile, that it doesn't develop critical thinking skills, push the capabilities of the brain. Neither am I arguing that you should hold back on teaching younger children basic skills, even if it's outside their core competencies and outside their natural area of focus (all that changes quite fluidly when you're young).

What I am trying to say is that at degree level, if you're mastering a field that has no intrinsic core mathematical content that you should be able to get certified in those abilities separate to maths ability. If an employer needs/desires a student to have mathematics abilities then they can request a certificate to demonstrate that.

Suppose things worked the other way and science majors had to produce a paper on Chaucer and Puritanism in order to graduate? Whilst IMO that wouldn't be a wasted educational experience, would be mind expanding, it's pretty orthogonal to the skills one needs as, say, an astrogeologist.

I'll hold back for as long as my computer does everything I need it to do with no trouble. These forced upgrades is how arbitrary obsolescence is implemented.
TV ad might not run arbitrary code. But its very annoying as well. Hence lots of pirating.
Something that might have helped that cause is skipping the behavior which resulted in widespread news stories saying Windows 10 was sending all sorts of potentially privacy-damaging information to Microsoft and you couldn't turn that off.

(Except in Enterprise. There you can turn it off. But Microsoft won't sell that to individuals.)
Would it be too costly for Amazon to just employ people to review most or all of their products, and maybe even rebrand the best products under its own brand where the seller agrees?

It would dramatically increase the quality of their store and brand, and it benefits from economies of scale.

Assuming they pay $100 for an high quality review, then a $10 item would increase by only 1 cent if at least 10000 are sold, which seem reasonable conditions.

For categories with many very similar items, reviews should be cheaper since a standard review procedure could be designed and applied quickly, offsetting the lower sales per items.
In what way are your suggestions better? Do you mean that they are actually more effective, or are you just talking about your personal preference?

Personally, I would have thought of better mental health care and limiting access to firearms and dangerous medications, so your proposal seemed very out of left field.
Is Apple really neglecting their pro users? I'm a pro user and after three years of using a Mac I'm just way way more productive than I ever was after ten years of Windows usage. Every time I see something cool in Windows 10 (like Linux subsystem, PowerShell package manager, etc) that might make me switch back I remember how shitty the control panel is, how cluttered the interface is, how bad the system search is, how poorly designed everything else seems. And yes, I know they're working on these things but the problem is OS X has had them for nearly 15 years now and Microsoft is still figuring it out. What is OS X/MacOS missing for pro users on the software side? I'll admit the hardware could use an update (likely later this year) but I'm pretty content with the way everything works in software right now. With macOS 10.12 we'll be getting an amazing new file system too.

I have to use Windows 10 for CAD software and sometimes playing games and it's inarguably the best Windows so far. Unfortunately, that's not saying much.
The cost of the Megaprocessor is documented here:
http://www.megaprocessor.com/Cost_Materials.html

The Megaprocessor uses through hole components. Something similar using surface mount components could be substantially cheaper, mostly because it could be smaller. This means it will need less of all the expensive supporting parts. The components themselves are only a small part of the cost.
This story partially addresses your question. It doesn't have enough details.

It truly amazes me, though I can confirm witnessing them (old and new users to the internet mostly), that there actual people who click on "One Weird Tip to Lose Ten Pounds"...

But even they eventually learn like the rest of us to be wary of them from what I have learnt.

My conjecture is that ultimately when new internet user growth rate slows enough, ads will no longer be a viable and naturally die out! The alternative, is that nothing changes, and that ads continue to derive value by consusensus of excessively consumerist and stupid people similar to the cult classic film, Idiocracy: https://en.wikipedia.org/wiki/Idiocracy

> if your SLOG is corrupted you just lost your entire pool

As far as I'm aware, SLOG loss does not jeopardise the pool, only the transactions that are in the SLOG. The pool may violate synchronous write guarantees in that supposedly committed writes that were in the SLOG effectively get rolled back (or rather, never get applied to the underlying pool), but that's about it.
Note that VMs often will not get the necessary IDs to entitle the PC itself to the upgrade. Switching between a VM and bare metal will change the entitlement as Microsoft sees it, and I'm not totally sure entitlements will work on VMs at all. Just in case, I'd upgrade the PC itself, even if you do it with a spare hard drive or something.

Thanks.

Actually organising the write up forced me to tidy up the code much more than I otherwise would have. I definitely find C# to be one of the more readable languages although I have had to debug and untangle some C# messes before.

Yeah I remember changing it to a SortedDictionary but I changed it back. I can't remember exactly why, possibly because it's supposed to be sorted by raw UTF8 bytes rather than a nice neat C# string and I didn't want to start using byte arrays for dictionary keys. I guess it only needs to be sorted when in the BEncoding format and it felt better to keep the internal structure as simple as possible. The tradeoff is it doesn't support incorrectly encoded torrent files – I'm really not sure how much of an issue that is.
Oh, that's simple. Democracy "works" only when majority of population is well-educated and cultured, and it tends to collapse when wast majority is ignorant, brainwashed by populism and dogmas idiots.

From the time of ancient Greek only educated men could be able to vote. That accounts for obvious early success of democracy. It also correlates with the notion of the bell curve (there is a famous book) you like it or not.

The utopian idea that everyone shall be able to vote leads to things like Brexit or that unrepairable disaster modern authoritarian Russia turned into.

Patients shall not vote for hospital's rules and medical procedures or staff election. Qualified well-educated doctors should. Students shall not vote for what they going to be taught (due to being not yet fully developed and brainwashed by media), this seems obvious.

But the idea of necessity of some sort of competent and educated "aristocracy" is one of the major ideas in political philosophy. The crucial thing is that members of such aristocracy must be quickly and easily replaced when fail or lost support. This, by the way, is how most of professional communities and university facilities are organized.

Truth is out there.)

No, I don't think that's really it.

The suicide issues in East Asia are highly contextualized to those cultures.

They don't live the same way we do.

They live in highly structured and organized societies with very strong social norms and obligations.

Add in some hyper materialism in S. Korea since the war.

The benefit of this social order is very low crime, fairly efficient society. But the drawback is that a small percent can't take it type thing.

You know how many gun deaths there were in Japan last year? Like one! Of course it has something to do with extremely strict gun control, but it has mostly to do with their culture.

It's not so much a 'workplace' issue so much as it is a cultural issue.

Actually, the majority vote is frequently one or both of these things. Whether or not this applies here.
Yes, the article is very old.

And also something that hasn't been true for ages. By way of anecdote, I've had to do config merges on major version upgrades more on Debian systems than FreeBSD systems, but even then the difference hasn't been all that great: major version upgrades just work. And the last time I had to build a custom kernel was FreeBSD 6, which was about a decade ago.

Any remaining pain is largely a consequence of the freebsd-update works and should mostly go away once the base system is packaged (which should also make security updates a little faster to install).

In France. There is nothing like that in UK.
This 2005 PDF is supplemental material for an old edition of "Computer Systems: A Programmer's Perspective” by Randal E. Bryant and David R. O'Hallaron. The 2015 edition of the book includes an updated version of this x86-64 content in Chapter 3, replacing the IA32 content and no longer a just a supplement. I strongly recommend owning a copy of this book if you have any interest in systems programming or just want to be exploit hardware characteristics for better performance in your userspace applications.

I took the class this book is written for, taught by the authors. They don’t place emphasis on being able to write assembly, since this is not a useful skill for the majority of programmers. Instead, the goal of this material is to get you to understand assembly and compilation well enough to 1) reverse engineer it if you need to for debugging or security reasons, and 2) be able to write compiler-friendly code, meaning code that can be safely translated into efficient assembly instructions (compilers are conservative, they only optimize when it's certain there's no repercussions).

Investors speaking without the chance of rebuttal from people who have significant experience in the subject is pretty useless.

> a majority of wolves

The problem lies there, not with democracy - whatever system you use, such an assemblage is going to screw the sheep over.

In a democracy, there's at least a sense of shared responsibility, and hence in real life there'd be a dampening of the wolf's id by each one's conscience.

In monarchic or oligarchic systems (and these terms don't have to be restricted to governments), the top person(s) will still probably end up being a wolf in such a condition, only now the other wolves would be "just following orders" and be more efficient in making dinner.
You continue to misunderstand and misconstrue my points. I don't see this going anywhere as, ultimately, you're the mod, not me. I hope he continues to leave useless posts complaining about articles he doesn't personally like, since that's what you seem to appreciate. I'll just note that I did, in fact, call his post ridiculous, but explained why immediately. It wasn't an insult in a vacuum. And when he replied with a similarly absurd follow up, I used sarcasm to get my point across. I was never rude for the sake of being rude. His comment bred any incivility which followed, and that's not "but he did it" -- it's just a fact.
That's a consequence of that software being written with only Linux in mind, not a problem with the BSDs as such. Also, somebody needs to write a port, and the only person who'll do that is somebody with skin in the game.

Obviously I'm an outlier, but if I need some software on FreeBSD, I'll contribute a port. Most of the time, it's almost trivial, and it's only with very obscure (maude is one that I'm currently working on) or newish (RethinkDB, which isn't written in a super portable manner - it doesn't even use pkg-config and has a hand-written configure script!) where there's an issue.
No. Well-educated, cultured individuals can be just as ideological and destructive as "mere plebs". Take a look at contemporary Academia.

What makes a democracy "work" is a set of established rules that secures the long-term development of the country.
The point is: Usually, you must know the rules to break them. In this particular context, looks like the original rules are fading away.

No rules = Anarchy.

Really, was this stated anywhere or did you just see this way?

> They wanted the ability to take down content that criticized the government, the PM, their government office, anything positive to Pakistan, etc. It was a power move to squash free speech, and they backed down. Terrorism was just a false flag.
