I'm very willing to believe SLS itself is mostly a political boondog, but I'm also still willing to give Nasa the benefit of the doubt that they're trying their best to get useful science/engineering out of projects like the Lunar Gateway. My understanding is that the lunar orbit they want would give a lot of interesting science opportunities and technical opportunities (simpler communications versus the "tin can on a string that blacks out for worryingly large periods of time" of Apollo communications).

If anything the Lunar Gateway sounds to me a lot like "classic" Nasa risk aversion and over-preparedness. It isn't strictly necessary, probably, but it sounds like it makes lunar projects overall safer (in communications access at the very least, but also reusing ascent stages, and providing more backup habitat space in cases of disaster readiness) and that's still good science to prepare for risk. (They don't want a second Apollo 13, and who can blame them for that?)

> The only reason to even consider using the high moon orbit is to have something, anything for SLS to do.

It seems like that is already disproven. The first few missions to setup Lunar Gateway modules have already been scheduled on SpaceX Falcon Heavy launches (in 2024) so clearly even Nasa understands they may have to rely on SpaceX even for access to Lunar Gateway orbits because the SLS has already missed deadlines. The "traditional" flipside to political boondoggle politics is "standard" commercial bids and contracts, and Nasa is far too pragmatic to rest important pieces of a scientific mission waiting for the SLS as the "only option".
Long notice periods typically soften the blow in Germany. After the first six months (where both sides can call it quits with two weeks notice and without cause) the notice period is four weeks to the 15th or last day of the month (and firing people without cause is no longer possible). There are some circumstances when that notice period is not relevant (if the employee is caught stealing, for example), but those don’t matter here.

From 2-5 years it’s one month (to the last day of the month), from 5-8 years it’s two months, eventually maxing out at seven months after twenty years. That’s the notice period for the employer. It can and often is asymmetric but can never be shorter for the employer than for the employee.

However, these are the legal minimums. Many employers will have longer notice periods in their contracts which apply to both sides. Something like three months or so isn’t uncommon.

Severance pay can even lead to problems with the mandatory unemployment insurance (which in most cases will pay you 60 – without kids – or 67 percent – with kids – of your last net earnings for a year) that can reduce the payout from that insurance (and then it becomes a game of calculating severance vs unemployment insurance, which can be annoying).
Reminds me of an early version of Product Hunt.
History does not show this is true.

Russia has historically been invaded by such people as Genghis Khan(actually his grandson, Tamerlane, Napoleon, Charles )I forget which one) of Sweden, and Hitler.

The USA on the other hand is protected by two oceans and has not had a foreign army on the continent since 1815.
My take:

The global recession which has been coming, but will peak in the first half of 2023 (as estimated by 22 CFOs interviewed recently, as well as economists):

The crypto shakedown is a leveling out so the Bain Capital type douchebags can mop up... recall, Bain Capital? And their primary douchebag senator who, was against cannabis UNTIL he left congress, then entered Bain capital and then proceeded to both promote cannabis whilst buying up in all the hedgey glory?

Yeah, thats whats happening to crypto.
Then simply don't tax fixed assets. Sure, sure, then people will simply avoid taxes by converting cash and other assets into properties that are not directly taxable, but that's just how these cat-and-mouse games go.
Not sure what your point is. It's still a design decision, not a technical one.
Is this a reference to something? I don't see how they're similar.
Understood, thanks, though I will note in case you missed it that this is in response to a comment calling my own evidence of autism.
True. The main problem with the Unix default is that there wasn't a way to set O_CLOEXEC on all new FDs race-free until recently. That's a real problem. FD leaks to children can be bad, but most of the time they are not the end of the world, and often one can steal a closefrom() implementation from a BSD or Illumos as a workaround when you know exactly what you want to allow the child to inherit.
I just started on ADHD meds after knowing I've had it most of my life and not wanting to be reliant on drugs. I turn 37 in 8 weeks or so. I have had bouts of apathy, have had some really rough times, definitely anxiety and sadness.

Still early days. I'm about 2 months in. I can feel the effects when I am on it. I can feel when it starts to wear off. No feeling of addiction at all. No dependence. No taking it every day like I've heard about for depression medication. Take breaks on weekends / on light work days without looming deadlines.

I actually like a big part of my ADHD brain more than the drugged version. Probably because I am used to it. But also I kind of like being multi-threaded by nature. It feels great to be able to do a lot of things simultaneously. The downside to this is it's very hard to be "present" in anything. This is where the ADHD meds come in.

I've been taking a lot of notes on feelings and side-effects since starting, and on the emotional side I feel a stronger sense of everything - from pleasure to joy to sorrow. Maybe it's the "present" part of it.

I have always been very good at "listening," well, hearing what people are saying and internalizing it/remembering it. But I've never been good at listening - in terms of applying critical thought to what people are actually saying to me. More like a note+file vs. analysis.

Some parts of me that have been dormant, especially the creative as in creating (not creative as in thinking) side of me has really sprung to life. And I'm enjoying that aspect the most.

Anyway, depression seems to be very far away from the side effects for me. It would suck and I empathize with anyone who has complications/side effects like that.

Actually, it's not simply the proportion, but the fact that over time the proportion of wealth held by the richest has been growing really fast. So, to use your analogy, I agree that a small number artists commanding the lion's share of attention can be fair, but if over time, an ever smaller number commanded an ever greater share, very soon every one would be listening to one artist and one song, and fair or not I don't think that would be good for Spotify, audiences, artists or anyone else.
> Active Recall looks compelling but it makes me uncomfortable that it says "try for free" but there's no mention of pricing that I could find. What's the planned business model? As a user of Anki for multiple years now, longevity with these products is pretty important to me.

Hey! This will turn into a subscription service at some point but I’m still working out the exact pricing model. Any data that you put into the system however will always be available to you and exportable regardless of if you decide to pay or not. This is mentioned in an email when you sign up but I realize that the communication could be better around this.

> Separately, it's pretty surprising to me to see the very first review by the "VP of Engineering at Shopify" without mentioning the fact that they are an investor in Active Recall. [0] Feels like this is counter to the FTC's rules on endorsements.

Dion was using the product long before he invested and it’s not something that we’ve been trying to explicitly hide (as you saw on his LinkedIn profile). I have updated the review to state that he’s an investor. Thank you for calling this out.
Once you've decided which programming language you're using, it's easier to choose a plotting library.
I think it's worth noting that the main attack described in the paper, against SIKE, depends on exploiting some behavior peculiar to that particular algorithm (what the paper calls "anomalous 0s"):

> The attacker simultaneously sends n requests with a challenge ciphertext meant to trigger an anomalous 0 and measures the time t it takes to receive responses for all no requests. When an anomalous 0 is triggered, power decreases, frequency increases, SIKE decapsulation executes faster, and t should be smaller. Based on the observed t and the previously recovered secret key bits, the attacker can infer the value of the target bit, then repeat the attack for the next bit.

While any leakage of information can in be exploited in principle, it might be that this technique is impractical against a target which doesn't exhibit some sort of behavior that facilitates it.

Yup.

Uhm... 0.0023 is 0.23% which is in fact one tenth of 2.3%.
Bellingcat.

Why do you say that? Their analysis of the Beirut fertilizer explosion was spot on.

And their work on MH17 was very good too.

Of course that pointed a finger at the Russians who were claiming not to be operating in Ukraine at the time so maybe I actually see why some would prefer to baselessly brush away the whole site as "propaganda".

Takes one to know one.
I think the key part of that idea is learning from the failures. Analysis and objective opinions on what caused the failure
So what you're saying with that example is that even with the backing of many governments that have a vested interest in doing anything to stop the bubble from bursting (something Bitcoin doesn't have), the greater fool theory ultimately was correct in that eventually the bubble burst? (I don't agree that the USD-Gold peg was an example of greater fool theory, just an example of how pegging your currency to gold as a sovereign government with a central bank is not a reasonable way of doing monetary policy. The gold standard is an outlier in the human history of monetary policy, the only reason it's so notable to us today is because it was in use during the development of modern economics.)

Cryptocurrencies do not produce anything and any actual transactions done using them (as opposed to speculative trading) are a rounding error even after more than a decade. There is no mechanism for them to be anything other than a complicated greater fool scam because ultimately the only way you can make money from them is if you can sell them to someone else for more money than you bought them for -- which is what a greater fool scam is.
Take Denmark for example that taxes software engineers 50 percent of their salary (it's not unique to SWEs it's just because nearly all SWEs will make enough to fall into this bracket). I'm thoroughly examining other lower tax bracket countries to move to because why do I want to pay half of my salary until I am enfeebled and the state lets me enjoy my enfeeblement?

Denmark consistently ranks in the top 5 of countries with the best quality of life. A year of parental leave, great social welfare, universal healthcare and retirement benefits, etc.

Including federal/state/local taxes, healthcare premiums, retirement contributions, disability insurance, etc, I pay close to 50% of my salary in the USA

And I'd still worry about how I'll pay the bills if I lost my job.

why do I want to pay half of my salary until I am enfeebled and the state lets me enjoy my enfeeblement?

Because that's how the state pays for the enfeebled today? Are you really suggesting you want to leave Denmark to go somewhere with lower tax rates, then when you need social healthcare, you'll move back to Denmark and take advantage of the healthcare system that you didn't pay for?
Not all timing attacks require any sort of privileged access. As one example, OpenSSH had a timing attack where under certain configurations a query for a non-existent user returned faster than an existing user, allowing attackers to enumerate user accounts.

I'm not saying this specific attack is something to get worked up over. But, as I have already said, writing off an entire class of vulnerabilities because you think it's all theatre is naive. Weighing each exploit against your attack surface, risks, and risk tolerance is not.

>It's security theater specifically because individuals and organizations following these blind mitigation recommendations don't assess the attack surface that's being exposed.

Blaming researchers for security theatre when it is the organizations which are not doing their due diligence is, at least to me, a weird way to look at things.
In many ways, IPv6 stacks are simpler than their IPv4 counterparts. The fixed packet headers are simpler and faster to parse, ICMPv6 includes both router and neighbour solicitation (as opposed to being separate protocols like ARP in IPv4), routers generally won’t fragment large packets in transit (instead giving way to Path MTU Discovery) and NAT is not so widely needed as it is in IPv4.

That said, the fixed packet headers being slightly longer means there’s actually slightly less room for the payload in an IPv6 packet compared to IPv4 on an otherwise equivalent link MTU.

I’m not entirely sure what to make of the results in the article though and the title really should be leading with asking why in order to be less sensational. The only explanation I can think of right now is that many routers have historically deprioritised ICMP traffic or even dropped it when under heavy load, but given that ICMPv6 is much more core to the functioning of IPv6 in general, it is perhaps not as feasible to do so for ICMPv6.
I’ve been building data visualizations for web for almost ten years. Most of the time it was some kind of dashboard with custom charts, interactivity and of course brand look.

Grammar of graphics always was this North Star for me. It is very helpful to go through papers and books and search for inspiration how to organize your system. But direct implementations are finicky to work with. And in my hubris I attempted to write yet another one implementation of grammar of graphics and it resulted in exactly the same problems!
With complex marks it is ambiguous what is a data point and what is a series. Tuning looks require this configuration objects scattered around chart definition and composition sometimes require to inject something in two different parts of definition.

Now I treat grammar of graphics as this collection of patterns and good practices. But surrender to pragmatic solutions when necessary.

Anyway I think I owe big part of my career to works of Wickham and Wilkinson.
So the problem is what happens to the old and new processes after the fork. To CoW, you need to mark all the pages read only in _both_ old and new which means that every memory write in the caller will now pagefault since the OS now has to lazily copy on both sides. So with true copy on write the fixed costs may be low but the marginal cost per memory write may be high in both parent and child.
In this case you can see why the resident set is copied, yes? It’s the smallest amount of memory that guarantees predictable performance subsequent to the call returning.
Absolutely, my observation is in a way that "most workloads don't seem (to me) to be like that".

The number of servers serving interactive queries (frontends, rest api servers, databases, etc) seems (to me) to greatly outnumber the number of batch jobs, and I've always seen those intentionally "over" provisioning CPU because otherwise you get latency issues if load increases at all.

I don't actually know that cloud providers don't either have some clever way around this (e.g. spending spare CPU cycles on some other form of work), or that it isn't the typical usage pattern, but I strongly suspect it.
For every localized case, including critical ones such as the army, historically super rich and powerful people would distort the system.

There are countless examples of rich or powerful and connected people buying officer posts, for example, and meritocracies (= equality of chances) stomping all over these corruped systems.

There's little reason to believe rich people willingly or not, do not distort every market they're in. That's why they become rich, to be powerful.
I work at a non-Google FAANG - from what I've seen in my org, "CS fundamentals" (which I assume is some proxy statement of sorts for leetcode-style interviews with emphasis on data structure/algo questions & knowledge) isn't as important for the work or to get hired for us. Our view is hard technical skills can be taught/picked up on the jobs, but behavioral aspects are not so easy to develop.

We routinely have & hire interns from top programs and many lesser known ones, or even non-CS degree holders.
closefrom() comes in handy for this. It's missing on some platforms (notably glibc and mac iirc) but actually not too hard to implement a work-alike.
> Have you considered that you're an outlier and that policy and approaches shouldn't be based on your outcome?

I don't think it's reasonable for OP to advocate for policy that would materially make their life worse. I'm not sure what you expect their response to be, but it's not going to be, "medication doesn't work for everyone? Great, I'll just go back to being miserable then so no one accidentally takes it unnecessarily."

Prescription medication is something you should work out with a doctor/psychiatrist who monitors your behavior and figures out whether the approach is right for you. But even if methylphenidate only worked for even just 10% of the people who have ADHD -- those people should have access to it. And the rest of the people don't need to take it, that's something their psychiatrist/doctor can work out with them.

> complete dismissal of people who have issues with drugging children

It bothers me that people read "hey, medication worked for me and didn't give me depression" as "literally everybody and their dog should be on this." I don't think that OP is the person here who's dismissing or generalizing.
After Donbas falls, if history is any lesson - the political situation in Ukraine will implode quickly. We might see a military coup and whoever takes over come to an agreement with Russia.

I’ve only driven a Y as a loaner, and although it’s 80% as good or better than X, I gotta say there are some features I still dig on the X.

X has more physical controls, which come in handy. It’s got a better steering control imo. We also got air suspension, which comes in pretty handy, especially while climbing over rocks in Colorado mountains.

That said, is it worth 50k more? No :) But we got an early model and got a bunch of tax credits and discounts, at which point it made more sense (and Y was not even announced yet).
Has IBM changed? My cohort of graduates in the 90's found them stuffy, extremely cautious and change-resistant. One fellow in my graduating class was chastised for wearing a shirt that wasn't IBM blue - "I understand you're trying to make a statement," (he wasn't) "but you won't fit in around here unless you make an effort."

He was told when he quit to join a startup "You know you will never work at IBM again?"

What a dinosaur.
I had it in my facial hair a few years ago. Two bare patches. My barber said it was likely stress-related (though I didn't feel stressed out at all). Then a year or two later it went away for no apparent reason. Nothing had really changed in my life that I could think would affect my stress levels. In other words, both its appearance and disappearance are a complete mystery.

I also have almost no hair on my legs below my mid-calf, and I did when I was younger.

I’ve often wondered if choosing Hertz as the name for “cycles per second” was some kind of scientific dad joke since 1 Hz ≈ human heart rate.
Fully concur, although now that I've read some of the white paper some of this doesn't even appear to be a real issue? Like the claimed "remote" attacks against, "Cloudflare’s Interoperable Reusable Cryptographic Library (CIRCL) [28], written in Go, and Microsoft’s PQCrypto-SIDH [65], written in C ... [are] meant to run in constant time"

But they just straight up don't run in constant time, so they're vulnerable to a timing attack across the network. That's clearly just a library bug? Like surely the dumbest part of a "constant time" algorithm is double checking that you ran for a constant wall clock amount of time?
Russia can find new customers before EU can find new suppliers (at least regarding natural gas), which is precisely why we're seeing increases in energy costs.
From the perspective of whoever is experiencing it, it doesn't really matter how it fits into the historical picture. What you experience is sitting in front of your screen while your family is having dinner, not points on a multi-decade timeline.
> However, I'd say from these that it's not clear that observed effects are the result of "changes in policing"; it's a hypothesis, sure, but not with close to the level of confidence you suggest.

Yes, because a lot of these studies were from the early days of the BLM riots. Things have solidified in the intervening half decade (although there's some uncertainty about how much of the 2020 surge is attributable to policing versus the pandemic, but I don't think anyone seriously doubts changes in policing played no role at all especially considering the homicide uptick begins promptly and dramatically after May 25, 2000). I don't think there are any remaining hypotheses (there is at least one niche hypothesis that is still a variant of the Ferguson effect--that the protests have caused communities to lose trust in police--but most studies refute it or find no evidence of it).

Here's the nber.org link again (I had to do some manual formatting edits when I copy/pasted, and I flubbed this link apparently): https://www.nber.org/system/files/working_papers/w27324/w273...

> f the hypothesis is that it was the protests that somehow resulted in... changes in policing... so actually, if the hypothesis is changes in policing, why not actually try to measure _changes in policing_ and correlate to homicide rate, instead of correlating protests and murders and assuming "changing in policing" resulted from the protests as an unmeasured middle step?

This is precisely what many of these studies do--they find reductions in policing and increases in murder rates. If you read the paragraph above the nber.org link, that's exactly what I describe.
