You do know where the term left and right wing actually originated? The German parliment, where the communists sat on the far left, and the nazi party on the far right.
If a person agrees to work for a company for a certain wage and continues to work for that company, how is that person "underpaid"?
Technically "wage slave" would make a better description than "underpaid".
But to explain the idea, civilized beings do their best to hold themselves to certain ideals beyond mere "consent". Bill Gates could, doubtlessly, afford to "hire" a black servant to willingly carry out his every command, submit to any humiliation, even endure physical punishment. We would generally consider doing so morally and ethically reprehensible, however.
As for right-vs-left, I'll just leave this here. I don't agree with everything in that (fairly short) essay, but overall it makes a solid case for Nazis as left-wing extremists.
I had the displeasure of working inside Walmart stores for four years. (Thankfully, not for them, just in them.) They printed on every one of their distribution packaging boxes at the time, "Collapsing this box and sending it back saves the company $0.11.) Now there's ROI as simple and as plain-as-day.
...Except they tried to use it to persuade underpaid retail employees to help the company out. I can just imagine countless stockers gleefully taking the time to make damned sure each and every one of those boxes could never get used again.;)
I think you're on the wrong side. News for nerds. Not news for ad sellers, like you.
Hey, as soon as I get that call to have a stable income with lots of perks, working two days a week and getting to save the world in the process - I'll take it. Until then...
"This allows the interesting dynamic of escaping zombification by committing suicide [...] The researchers say exactly the same process of model-building, data gathering and simulation works equally well on real diseases such as influenza"
Y'know, We all know that sometimes the flu makes you feel like you'd rather die then spend five more minutes sick, but did TFA actually suggest (accidentally or not) suicide as a means of avoiding the flu?
"Stop-n'-Drop brand suicide booths: Better selling than Nyquil since 2017!"
What if I am in extreme pain but it is not life threatening and the lab test for the bacteria takes two days?
Opiates do amazing things. Pity, really, that some humans have a problem with moderation, because vicodin counts as the single best flu remedy ever.
Are you going to be the one that rejects giving the whiny mother the antibiotic only to have her child die?
Not too many people die of ear infections - Even mild hearing loss counts as a relatively low-frequency outcome. And unlike the whiny mother, a real live doctor can actually tell whether the screaming kid has a serious risk of dying or not. That said - Yes. Yes, I would make that call, and I would defend it after-the-fact, if felt I had made the right decision up front. People die, and that includes sick kids, that even includes me! And I can accept that. But y'know, if I someday die of polydrug resistant TB rather than heart disease or cancer or a bus or "misadventure", I sincerely hope an afterlife exists just so I can haunt every GP who helped make the fluoroquinolones useless rather than dare say "No!" to their patients.
So we can waste them on livestock and toddlers with viral ear infections but sufficiently-whiny mothers?
Fuck that! Until the FDA and the WHO outright ban the use of ALL antibiotics, including for veterinary use, without the presence of either a (human-)life-threatening situation or a positive ID on the pathogen, I have zero interest in helping our little "better than apex predator" buddies evolve resistance to yet another class of effective ways to keep me alive when they decide I look like a tasty place to raise a family.

if the paper generates enough heat to fool the robots, it would also generate enough heat to cause the magnets to lose their magnetism. Rare earth magnets, maybe not -- but telephone headset magnets -- definitely.
NIB (the most common "Rare Earth" type) magnets actually have the lowest Curie temperature of any common magnets (as low as 300C), and the much more common AlNiCo magnets have one of the highest (up to around 900C). Both of those exceed the temperature of burning paper, however, at around 232C.
The NSA wants to have access but keep others out. Known vulnerabilities let the "wrong" spies in. Why do you think *cough* "DLink" *cough* released this patch, anyway?
And lately, the retarded concept of the security questions that the user cannot choose (or can choose from a set or around the same 10 in every site).
You realize you don't need to answer those accurately?
I treat security questions as the emergency sticky-note under my desk, in that I will answer them however the hell I want, then just make a note (not sticky, but yes, an actual physical offline note) as a clue to what I picked.
I figure if someone wants to impersonate me, they already know my mother's maiden name; they probably don't know that on site XYZ, I answered that question with "Diet Coke", with my written clue to myself something like "Mom: Bottom button" (which for a soda vending machine I occasionally use, dispenses the aforementioned soda).
That said, I don't forget passwords, so I could just as well answer "asdflk$hjq2-34lk" for all it matters.:)
Because, you will, most probably, not walk without pain for another 20-30 years.
Believe me, as a hiker, I fully appreciate the difference between "walking" and "full range of motion without pain", and you have my sympathies if you do too for practical reasons.
But make no mistake - Getting to walk around the block a few times every day, getting to walk to the local store, getting to walk period, far beats "can't leave the sofa without agonizing pain".
There's almost never a magic bullet treatment, for any disease, mental or physical.
I have to disagree... If I get strep or pneumonia, they give me a z-pack and bam, it magically goes away. If I have a broken finger, they give me vicodin and bam, I magically don't care about the pain (though yes, the finger itself just takes time to heal). If I have insomnia, they give me ambien and bam, I can magically sleep again. When my knees or hips eventually wear out, they give me new ones and bam, I magically get to walk for another 20-30 years. And keep in mind that many of our "magic bullets" work on a larger scale and longer term scale - Vaccination, water sterilization, sewage treatment, annual physicals, etc.
Even for the things that still tend to kill us, like cancer and heart disease, we have a lot of magic bullets that let us live far, far longer than we would have a century ago. Case in point, we wouldn't have various religiots arguing over their "right" to murder (as in the case from last week) their 10YO daughter by refusing treatment for a 95% survivable form of leukemia. She would simply have died, no moral issues involved.
But for mental diseases, it gets a lot messier. There, I would have to at least partially agree with you. We have plenty of ammo, but precious few we would dare call "magically" effective. Perhaps more like "napalm", where they might get the job done, but with so much collateral damage that you have people going off their meds because the cure sucks almost as much as the symptoms (to give my metaphors a good stir there).
Perhaps more to the point of TFA, I would have to agree with its author. We need to get over this societal PC BS that every sociopath and drooler can, with the right care, grow up and lead a productive life as a rocket surgeon. Some people will never manage more than wiping their own ass, and some people will never grasp why they can't "earn" their living pointing a gun at convenience store clerks. Simple as that. Best for us, and best for them, to keep them off the streets until such time as we can cure "criminal" with a magic bullet - Preferably starting the process before they take a real bullet from an armed victim or a cop or a partner crossed.
Its almost like they WANT an uprising on their hands...
Imagine the frustration of today's governments. They imprison us en masse, they torture us, they let the 1% rape the 90%, they basically piss away the rights we took back from the old-world monarchies as fast as they can...
And we just sit around and take it. "Oh well", we say, "at least they keep me safe from dying of something slightly less likely than choking to death on a goldfish".
Can you see how unsatisfied our leaders must feel at that level of rolling over by those they seek to oppress? "Stop hitting yourself in the face", the bully says, and here we stand around actually hitting ourselves in the face over, and over, and over. Takes all the fun out of it!
they might act out of self-preservation because tax evasion would be too easy in a parallel economy [...] no private power can raise taxes or pass laws to unwind monetary excesses.
Way to miss the point, Ed.
The governments of the world have proven themselves much too irresponsible to manage fiscal policy. We-the-Fuckin'-People have, therefore, decided to take that power back from the government.
When a government can't keep its own spending in check, "raise taxes" does not count as a valid response, whether or not they have that power by virtue of having the biggest guns. The interests of the world's governments have drifted so far away from "public-minded" as to make your entire suggestion laughable. No, we obviously can't trust most private entities to act in our best interests - But I could name literally a hundred that do a hell of a lot better job than any world government.
The federal reserve and the ECB need to cease to exist, ASAP. No more of this "implicit taxation through inflation" crap - If governments can't play on the same monetary field as the rest of us, they need to go away and have something better able to live within its means replace them.
The peripheral legal implications aside, and at the risk of sounding like a Google apologist, I really can't say I have any problem with this.
The sort of people who want to install CM will still have absolutely no problem going to the website and doing it manually. This presents no barrier to them exercising their choice of how to use their hardware.
On the flip side of that, having it in the Play store presents something of an outright danger to people who don't know any better (aka "the vast majority")... "Oh, a new version of Android? Hey, I have an Android, I should grab this!". Ten minutes later, their battery dies, or they get sick of watching the installer screen and interrupt it. Oops! Partial brick-time, and now Google (via Samsung/HTC/etc, via Verizon/Sprint/etc) gets to deal with thousands of self-inflicted warranty issues.
Again, at the risk of sounding like an apologist, Google has made compromises that let power-users do whatever the hell they want, while providing 99% of the "walled garden" experience most users want.
If you're somebody who on average buys one bar of Cadbury Dairy Milk on impulse once a week, can I encourage you that it's actually better value to buy a pack of four when you're doing your next online shop?
No. No, you cannot. Because:
1) Most people prone to impulse-buying your crap would eat it all the same day it arrives,
2) Impulse buyers tend to act on impulse, and wouldn't actually seek it out deliberately, and
3) People intentionally buying chocolate buy chocolate. Not your "HFCS, carob and soy lecithin" garbage.
Now, if we consider junk foods beyond just candy, let's consider margins of impulse-buys vs planned buys. I happen to like Doritos. Yeah, complete crap, and bad for me, but I intentionally (whether impulse or actually on the list) buy them every now and then.
As an impulse buy, I pay basically a buck for a 1.5oz bag of their crap. For two bucks, I can get a full-sized bag. So, Frito Lay needs to ask itself something - Can you afford to sell Doritos without the insane margins on your "vending-machine" sized packs? Or do those basically subsidize the price of "family packs" that you may well only sell for the purpose of keeping us "hooked"?
Because the same logic applies to almost every less-than-bulk sized junk-food out there. Sodas make a great example - a 20oz soda at the register costs MORE than a 2-liter bottle. A 3-pack of gum in the candy aisle costs less than a single pack of the same gum at the register. Can "impulse-buy"-centric companies actually afford to sell only their more economical sizes?
it's a 30 hz (read: 1/2 of the supposed maximum for the human eye which has been debunked) 4K display. Even the worst of TV's can handle a proper 60hz at all resolutions.
True, but only by a technicality.
Refresh rates haven't mattered nearly so much since the bad ol' days of having an electron beam scan a screen so it updates in pulses of brightness. At 30hz, a CRT causes massive headaches. At 60hz, most people could feel the eye strain after a while. But with a display that doesn't flicker, none of that applies, at any "refresh" rate.
If you actually had a true full-4k feed at 60+hz (and did I miss the announcement of a mainstream optical media format that holds more than a terabyte?), you could - marginally - detect the difference in a rapidly moving scene. For writing code (the biggest reason I've seen Slashdotters' mention lusting after one of these), you won't even notice refresh rates down to the 10-15fps range.
I do understand that some people prefer 'join' statements over nested queries. I do not know if that would be faster/better to do 'join' statement over multiple huge data tables compared to nested queries.
Subqueries, particularly nested ones, virtually never count as the best way to write a SQL statement. You'll occasionally do an update against one to get around stupid limitations against using aggregates or partitions in an update statement (though in those cases, make damned sure it actually does what you mean it to do), but even that falls into a serious minority.
Overall, your first pass at just about any query, in the absence of of a specific known reason to do otherwise, should always use joins rather than subqueries. Then you look at the execution plan and pull out the stupid.
Maybe you'll rephrase part of it as a subquery (but virtually never nested subqueries), maybe a CTE, maybe add an index, maybe even break it into multiple updates on a temp table (you can index a temp table, you can't index a subquery). But all of that assumes you work with some pretty hefty queries - Not the sort of "hello world" you'd ask someone to write in a job interview. If I ask you to come up with a quick and dirty mailing list for each customer that bought more than 10 widgets last year, you'd damned well better have three tables, two nearly-trivial joins, one HAVING clause, and zero subqueries.
They already know as much - Thus having polygraph evidence inadmissible in court and illegal for virtually all employers to demand of their workers.
As usual, though, the government counts as the absolute worst offender when it comes to "Do as I say..."
More to the point of TFA, though... It sounds just peachy that Uncle Sam knows about "all" 4,904 people who bought this thing directly, but what about the 4.904 million who simply downloaded the PDF for free online?
But SHA1? right now, according to wikipedia, a full collision attack requires something like $2.77M of computing power on the cloud...
Let's say Merck has a new drug in phase 3 clinical trials, it seems to cure cancer and the common cold. They plan to publish the results of the trials tomorrow, and everyone expects great success
If you can crack RC4, you can MitM the private session between Lead Researcher Fred and the board. Whoah, this miracle drug works as advertised, except it causes permanent impotence.
Time to short Merck, and go all-in on Pfizer, and a few million up front amounts to chump-change compared to what you'll make tomorrow when the news breaks.
Slashdot Mirror
You do know where the term left and right wing actually originated? The German parliment, where the communists sat on the far left, and the nazi party on the far right.
The terms "left" and "right" appeared during the French Revolution of 1789 when members of the National Assembly divided into supporters of the king to the president's right and supporters of the revolution to his left. One deputy, the Baron de Gauville explained, "We began to recognize each other: those who were loyal to religion and the king took up positions to the right of the chair so as to avoid the shouts, oaths, and indecencies that enjoyed free rein in the opposing camp." However the Right opposed the seating arrangement because they believed that deputies should support private or general interests but should not form factions or political parties. The contemporary press occasionally used the terms "left" and "right" to refer to the opposing sides.
You should probably find somewhere more intellectually honest, well-informed and less racist, like Stormfront on Hitler's birthday.
If you have a factual objection to a mere 1.5 page essay, feel free to post it. Perhaps I missed something critical that you spotted right away.
If a person agrees to work for a company for a certain wage and continues to work for that company, how is that person "underpaid"?

Bill Gates could, doubtlessly, afford to "hire" a black servant to willingly carry out his every command, submit to any humiliation, even endure physical punishment.

And socialist, at that... Naziism was hardly socialist, name notwithstanding.
You, uh... You might want to read up on the term National Socialism.
