Sometimes, when tissues are deprived of oxygen, they undergo apoptosis when the oxygen is restored, not when they are deprived. This is why people who undergo heart attacks are sometimes rapidly chilled to core hypothermia. The cold discourages their tissues from committing suicide when their power comes back on.

It's hard to imagine something worse to be honest. These vulnerabilities basically amount to ripping away the entire veil of protections at every level that we've built up over the years.

Future vulnerabilities that I could imagine being "worse" would be either encryption vulnerabilities or signals level vulnerabilities.
Very old in the arena of cryptography.

No one in the CPU Architecture Design arena put 2 & 2 together [1] to realize that the same side channel that was devastating for cryptography work would also be quite devastating for bypassing memory permission protections in the CPU's they were designing.

[1] probably because the intersection of "cryptographers who can mount timing side channel attacks" and "CPU Architecture designers" is very close to zero.

The commenter you replied to was being very sarcastic.
A fence of some kind that stops the speculation on access to protected address space would be better. Trying to stub out values would mean you have to throw the speculation out anyway, and a fence could be setup to prevent access. This might still allow an attack on kaslr since you could use the timing of the speculation to determine if a fence got hit or not.
You bring up a good point. That being, wealth can't be measured in monetary value only. Yet another case where GDP isn't tied to wealth.
We should have a number that combines numbers like GDP, average net worth, average wage and inflation. This may give a better balanced picture of an economy. The current GDP growth is pretty useless if it goes mostly into the pockets of a few.

Government checks can't bounce.

Unless they give up sovereignty over their own currency of course. A mistake made by European countries - several of which have paid and are continuing to pay the price.

I absolutely agree that too much public debt is a bad thing, but not for the normally given reasons. It can lead to inflation, devaluation of the currency in relation to either goods or investment asset prices - indeed we see the latter at the moment in stock and property markets around the world, although that is driven by money creation through private lending. This is more worrying, as private checks can and do bounce, debts default, and we get another financial crisis.

Govt debt should be used for capital investment - roads, communications, health, education and security facilities - and if so used can be a true investment with an expectation of future returns. Debt that blows out on operational expenditure, transfer payments, public sector bureaucracy bloat, is not sustainable.

> If sugar is not bad for you and you cut back, you've given up on a few pleasures, but in the grand scheme of things, you've lost nothing.

I disagree that giving up sugar and sugary stuff is the same as giving up on a few pleasures. That just sweeps the issues under the carpet, so to speak. Depending on the person, giving up sugar can be a whole lot more, and for some people it may be equivalent to giving up the biggest pleasures and the biggest supporters of existence itself. Tangentially, sugar is one of those things that's not as easy to give up for most people because of how our bodies are wired (and have evolved). The dopamine effect, the reinforcement and the need to up the intake to get more pleasure can be a serious hindrance even to the most rational, thinking and open minded people.

I feel like this effectively makes Twitter an avenue for propaganda dissemination, giving world leaders who frequently blur the line near facism a "no-rules" platform to give out (mis)information.

> Life itself is a complex system that radically altered its environment - and here we are now, billions of years later.

We are replacing complex systems maintained by homeostatic dynamic stabilities with simple systems requiring continuous inputs from the very systems we're deconstructing. And we're doing so on drastically asymmetrical time scales -- we're increasing the complexity of the replacement systems orders of magnitude more slowly than we are deconstructing existing ones.

> I'm not a climate change denier. The problem is very real

Climate breakdown is not the problem. It's just the most exigent of literally hundreds of breakdowns caused by a malignant ideology (unending so-called economic growth). We have only 50-70 harvests left due to rapid topsoil loss. Freshwater is disappearing fast. Most ecosystems on the planet are in various stages of collapse.

> There are ways to deal with it

If we put all hands on deck and made it a global priority, we might avert the complete breakdown of the stable climate our agriculture depends on. Whether this would be enough to deal with other crises is questionable. It would be worth trying.

But the question is irrelevant, because all hands are not on deck. They're mostly working on trivia, warfare, and further ecosystem destruction. There isn't the slightest hint that we are ready to deal with any of our global crises (indeed, on most issues, we're slowly retreating into national, mutually-hostile bunkers).

I mostly agree with you, but I would frame things differently.

We are animals, and everything we do is part of nature.

Nature isn't either inherently good or evil, and natural processes can be self-destructive.

And while we probably don't have qualitatively unique features we distinguish ourselves quantitatively on many axes, especially when it comes to storing and transmitting information and
therefore influencing the rest of the world.

We may be more powerful than other species, but I'm afraid that on the knowledge/wisdom scale, we're only good enough to be dangerous. Seeing ourselves as a part of nature is necessary to limit the damage we do.

> I suspect that commuting traffic will increase to eliminate this advantage.

I think maybe in the short term, but in the long term I can imagine self driving traffic moving much faster than regular traffic. Cars all accelerating at the same time at lights, Uber pool in vans becoming super cheap. Roads could dynamically add and remove lanes in a direction without needing infrastructure, since all the cars will just "know" which lanes are available. Personal cars (hopefully rarer) can drive themselves home rather than take up parking space in cities.

I'm fully aware that it's frowned upon. There is definitely no malice intended. Perhaps there is a bit of social ineptitude, but this is the internet.

Let's put it this way. What I said is a generalization, and I framed it as a generalization. In no way did I say it applies to all people. But generalizations illustrate fuzzy truths that are as the adjective aptly states: general.

The parent poster also said something very general. He said that, and I quote: "50% of coders are macho, taciturn, unhelpful frat bros who make anyone who is not a member of their boys club most unwelcome."

There are two ways I could interpret what he said. I could say what the typical millennial would say when he/she encounters anything slightly sexist/racist and tell him that just about everything he said is insensitive, over-generalizing, frowned-upon, and kind of just untrue.

Or I can see things from his perspective and realize that although he is stereotyping, he is definitely illustrating a generality that is a fuzzy aspect of the truth. As a straight male myself perhaps I can say something to help him see things from a straight males' perspective. Of course I would be giving him another generality but a fuzzy truth is still a type of truth.

I want to change what it means to be progressive. The reality of this world is that things are rarely ever fair, but the meaning of "progressive" has become twisted in recent decades. Progressive has come to mean not only treating all people equally, but to state that all races, sexes and people are equal in mental and physical ability. This is not true. European people are taller, asians are shorter... what black magic enforces the attribute that while physical qualities may be extremely different for all peoples, intelligence remains identical across racial boundaries?

This is not a pretty picture but to say that all are equal is to deny reality. Can we be progressive without denying reality?

Take the following stereotype, for example: Men are generally physically stronger then women and thus better suited for jobs that require more physical strength.

I've literally met "progressive" people who deny this reality. This is borderline insanity in the name of progressiveness. We've gone too far.

I support progressiveness, I support equality in judgement and treatment, but I cannot deny and I cannot unsee the reality of the unbalanced universe we live in.

I want to mention that I have had one instance in my life, being a straight male where I have become bros with a gay male. From my perspective we were just bros, his perspective was different. But that is besides the point. I just want to say that I am in a good position to sympathize with both the stereotypical "macho straight male" and the gay male, so it is of my opinion that it would be highly unwise for the parent poster to dismiss what I say too quickly.

It it's just one of timing attacks possible on x86. Cache miss timing has been used in the past to create covert channels and exfiltrate keys. Memory controller issues have been explored too. Modern general purpose CPUs sacrificed some security for performance.

There are few security or performance guarantees. It is not an architecture geared to realtime and fully deterministic operation.
Postgres’s MVCC implementation with immutable tuples means every write to a table affecting any index touches every index on that table. Excessive indexing will have a performance hit in any DB, but combined with Postgres’s architecture it’s particularly bad.
> CL type declarations tell the compiler it can remove runtime checks.

That's not true. To tell the compiler that it can remove runtime checks you declare the optimization quality SAFETY to 0.

The Common Lisp standard does not specify what type declarations do and what the interpreter or compiler does with it.

Some compilers will never check types. Some will use them when SAFETY is low as assertions and remove runtime checks. Some will use them as assertions both at compile and runtime.

> They are performance optimizations. If anything they decrease type safety.

That depends on the implementation and the compiler switches.

In SBCL by default it INCREASES type safety:

It's still not completely clear. I haven't been following this case specifically, so I don't know other details that may have come out, but there can easily be mitigating circumstances. Maybe they had a cat and mouse game going on all day, and she had been doing the same to him. Maybe he was merely reciprocating an inside joke. He wasn't her boss, so that sort of game wouldn't be a big deal.

I'm sure this sounds to you like I'm reaching, but I can think of many, many similar circumstances where I've done something completely innocent in context that would get me skewered if taken as a sound bite or a picture. That's why I'm slow to take the man's career.

If that trillion dollar investment earns more than the cost of interest on it, then we are better off.

You seem to equating "military spending" with "lighting a mountain of money on fire", which is intellectually dishonest. To put things into perspective, a medium-sized military base will generate roughly $5 billion in economic activity and contribute to ~50,000 full time jobs. A trillion dollars is enough to put a new city on the map.

Military spending isn't limited to tanks, it also directly contributes to scientific research, technological advancement and improvements in manufacturing techniques.
I think most people who supported #MeToo or #BelieveAllWomen do not believe in abandoning the legal system, though they may be discussing adjusting the legal system such that we actually see more convictions of rapists, assaulters, etc where the evidence succeeds in proving the accused party guilty beyond a shadow of a doubt.
Again, all of this is extremely muddy by nature and will stay that way. There are innumerable variables in every single case: the intent of the accused, their credibility, their track record regarding these issues, the circumstances of the perceived attack, the credibility of the accuser, which of them is actually telling more of the truth, anything that was documented, on and on and on.

Right now there is a revulsion in the public space because of the real bad cases like Weinstein, who had a long and seemingly well known track record for abusing his station to get sexual favors from women in his industry, and use of his connections to keep it quiet from people who would've made it public. That needs to fade away before there's any realistic chance of a rational discussion. Yes, some people are going to get caught in the crossfire and that's unfortunate, but I don't see a way around it.
Sadly it's a bit more complex than that. Because currently running different transactions may hold a view of the database as it was before the transaction commits, the actual view of what does can be reclaimed depends on what transactions are currently active. Thus upon commit, it may be that some tuples release by the committed transaction are still visible to others.

Vacuum actually works by looking for tuples where no running transactions can see them anymore. Postgres, in effect, maintains a minimum and maximum transaction ID that any tuple is visible for, and vacuum scans over all of those that have a max visible transaction ID (suggesting it's available to be reclaimed) and which is less than the minimum active transaction ID.
People have been suspended from Twitter and required to delete posts for pretty mild, joking stuff like "we should get rid of men", but Trump has not. @jack has stated a few times that Trump gets exempted from the rules because of the "newsworthiness" of his tweets - this just makes that official.

Who said the US system was better? You're attempting to stand up a strawman counter.

I said socialized medicine requires heavy rationing of care. The comment I replied to was implying that somehow the selection of and or limitation of care is wrong (eg under the US health insurance system): all socialized systems depend on that exact approach, aka rationing. They limit access, they restrict types of therapies based on age or expected outcomes due to cost, they extend wait times dramatically based on what they decide is more or less important, and so on. Socialized medicine would collapse instantly without such aggressive rationing.

And nowhere in the above paragraph did I say the current US system is superior to alternatives in the developed world.

I liked the first edition of K&R a lot. Today I suspect it shines most when compared to recent intro language books. It was succinct yet offered insight into both the language's design concepts and its implementation -- an introduction to software based on Strunk & White's spartan model of exposition.

Given the abstract nature and swiss-army knife mission creep of today's languages, it's a rare intro PL book today that's smaller than 600 pages. (K&R 1978 fit into a mere 220.)
