Reading “Catch-22” Reminds Us That Sometimes It’s Noble to Quit
That advice seems like unnecessary mental gymnastics.

Just take an unseen technical problem, solve it for the very first time in front of a colleague, then double your time as the expected time for candidates in an interview.

When you're under time-pressure, you actually spend more time thinking about how much time you have left, rather than thinking about how to solve the problem.
Actually now that I look at it again it's mostly the icons that aren't rendering nicely. I've got OpenDyslexic installed in the OS and then set as the font in firefox setting but for what ever reason "up arrow", "down arrow", etc are rendering at text instead of icons. Any tips to fix this?
Thanks! I like this proposal a lot.
Like the “guess who?” game?
They should really be paid at the comp rate of the position you are hiring for (which is... a lot more than $50/hour for the Bay Area employers who have given me take-home interview problems).
Well, then. There's the solution. From now on, I'm bringing my attorney to all my on-site interviews. :P

And now this : A Twitter insider was responsible for a wave of high profile account takeovers on Wednesday, according to leaked screenshots obtained by Motherboard and two sources who took over accounts.

Yeah fair, I was a little harsh. This is clickbait, though built on the confusion of a specific scientific meaning and the commonly understood meaning.
True, but it makes you a suspect for further investigation.
> Once we became aware of the incident, we immediately locked down the affected accounts and removed Tweets posted by the attackers.

@elonmusk was posting and deleting the scam tweets for hours. In what world is that "immediate"?
You could move many, many millions of dollars on the stock market with these accounts. Would require more care and/or tricks to avoid being apprehended than a simple anonymous bitcoin scheme, but the pay off could have been at least a couple of orders of magnitude higher.
Let's not forget the ongoing breach is being used to con people. Maybe that was the representative's concern.

> Maybe you shouldn't use a free service that is not under your control or any proper regulatory or quality constraints for your most important messaging to the public then?

What are you referring to exactly? I thought the govt had their own IT and websites across the board, and only used things like twitter to aid in communicating to the public.
what was the outcome? did they catch the criminals?
I suspected some sort of internal tool was used to target prominent users but I’m still curious why there were thousands of unverified accounts tweeting the same scam. Searching for that bitcoin address pulled up tons of accounts tweeting it shortly before that term was blocked. Are there really that many trolls out there, or was a very large set of accounts hacked?
I definitely don't think Obama/Biden/others would DM.

But Elon? Some of these bitcoin exchanges? Maybe. How about accounts that were accessed (if any) that never blasted out the bitcoin tweet, but had their messages harvested?
Twitter investigation suggest that this is a coordinated social engineering attack [0]. The idea that the hackers are some non state actors and not from the US seem unlikely.

G did not really get serious about infrastructure security until after the China hack (and more-so after NSA/Snowden) and didn't really get serious about insider risk until after "gcreep". Still, I don't understand the reluctance of the industry at large to learn the lessons of other people's failures. Why does each company need to separately discover that insider risk cannot be prevented by recruiting, it has to be prevented in code and hardware?

Building a large-scale information system is like building a nuclear power station. There are a million ways to screw it up and only a few recognized right ways. If you ignore the best practices, it will eventually destroy your company and harm your users. Twitter have nuked themselves here. How can they come back from this? It sure looks like an insider risk mitigation system would have been money well spent.
I agree with you.

Also, I really hope there’s a set of users whose accounts cannot have new devices connected without special authorization, and if so, you’d have Biden, Obama and Trump on that list.

Edit: 5 minutes after posting, I saw Obama and Biden were on the list of people hit, and I missed it in the early reports. Unbelievable.
Not a physicist, but as far as 2 goes, galaxies are all atoms interacting after all. Filaments themselves are emergent structures formed from the interaction of large amounts of mass-energy at the largest scales. Forces have different ranges (scaling behavior) thus the behavior of matter changes as you change scales. At the largest scales it is mostly purely gravitational to my knowledge (plus dark energy which is also modeled gravitationally).

When you play billiards you don't expect them to gravitate toward each other! If they were on the scale of planets though, you might (it depends on how you scale their velocities). Or if you waited extremely long times, and were not under the influence of Earth's gravity you also might notice in billiards.
Nice! I regularly dig through NixOS docs, follow them on twitter, chat on the IRC channel and this is the first time I've come across the mobile-nixos stuff!!
Ah well my concern with eating red meat is related to the cancer risk and the impact on climate change. Are you worried about these issues in relation to your diet?

Independent Print and Copy shops are pretty common still, meanwhile every shipping store (eg: UPS Store, FedEx Office, local independent mail shops) and library offers inexpensive printer use.

Hard to build a business when there is ubiquitous existing supply combined with most home printers having much higher ink costs and dodgy print quality due to lack of use/maintenance.
When you're under time-pressure, you actually spend more time thinking about how much time you have left, rather than thinking about how to solve the problem.

It's like that parable.

2 students approached the master, wanting to become swordsmen.

'I want to reach your level in 10 days', said a student.
Master replied 'It will take you 10 months'.
The other student said 'I don't care if it takes 10 years, Master'.
The Master said 'and you will learn in 10 days'.
The most reasonable explanation might be that they’re lying to sound cool. Bribery is a thing, but any twitter employee would know that their employment (and future career prospects) would be terminated.

On the other hand, $1M in BTC might do the trick. Interesting thought experiment...
Among my work colleagues, friends, and family, it seems alcohol consumption has either slightly increased or significantly decreased.

I made a conscious choice as Coronavirus was just getting its shoes on to completely stop drinking alcohol. I haven't felt this great in ages and intend to teetotal beyond the crisis.

The occasional dinner out with drinkers since some of the restrictions were eased has not been a problem and - company depending - as enjoyable as usual. I'll probably skip the pub socials when they reopen but dinners, lunches, and sports seem fine. Next stop: more exercise!
The point of a science article like this is for the journalist to act as an intermediate between the scientists and the public. Their job is to communicate an understanding to the lay public using familiar terms and concepts. To let the public learn some part of the wonder of the universe and to let them appreciate the work the scientists did.

To do this you have to focus on communicating understanding rather than pure technical accuracy.
yea there are a lot of people on twitter poking fun at the fact that there were probably MUCH more lucrative things you could have done with that kind of access. Seems like a quick smash and grab by some teenagers or something
I'd argue against this. I find videos to be useful to showcase the product especially if its in the early stages which is what it seems like from their website.

But I agree trying out the product, would make more sense. In that case I would shoot an email to request the trial if it really solve the problem.
I call these high stakes interviews "the perfect dismount".

You can feel the pressure mount - any algorithm that doesn't run on the first try or second (with a couple of quick fixes) and you're being mentally discounted.

The same for silence - if you're thinking through something, take abnormally too long, you're discounted.

The Perfect Dismount. A 10.0 is what's needed to land a FAANG job.

Interestingly, the people I've spoken to here are perfectly happy to criticize the Cultural Revolution. My impression is that saying anything negative about Mao in his later life would be fine, so long as you couched your denunciation in a way that didn't implicate the contemporary CCP.

I suspect that an impassioned defense of the Red Guard would get more blow back here than in the USA, actually, based on my friends' opinions.
Marco Rubio is a good example of a Hispanic person who is treated as white in practice. When I was talking about a subset like that, I didn't mean white Hispanics so much so as subgroups defined by religion, and especially politics. Basically, there's a "presumption of non-whiteness" for Hispanics, but it can be overcome by individuals and communities aggressively embracing the "white" virtues (and denouncing other Hispanics who do not).

And as for Asians, you can easily observe the dynamics by first looking at the "yellow peril" scare, or, say, the justifications for the internment of Japanese-Americans during WW2 - and then compare it to how the same groups are treated today. The difference is obvious and immense.

I do agree that "white" is a bad term for it overall. But thing is, it's a pre-existing one - the reason why we talk about stuff like "white privilege" is because "white" and "non-white" was the language used to get us where we are, and the same distinction (usually obscured shibboleths like "inner city youth") is what largely fuels systemic racism today. So it's impossible to meaningfully talk about racism without talking about whiteness.

(I'll also add that SJ vocabulary is pretty bad overall when it comes to conveying concepts accurately - e.g. "privilege" is another highly misleading term that I wish was never popularized to describe the very real concept behind it.)
It is that isolated bubbles generate environments spreading and reinforcing dangerous information. E.g. spreading alternative medicine cancer "cures" will kill people. I believe everyone needs to be exposed to different views once in a while.

I agree, also remote employees might not have the same layers of security as they do if they were in the office. For example, there could be a firewall that blocks malicious code at the office or someone is logging into the VPN on their home computer that is infected with malware.

Apple was interesting because they have 3.8m followers and zero tweets. Maybe they've never tweeted. But today they did.
If the ships only carry 4 TEU (or 4 FEU), then lashing is likely not needed if they use Twistloc's welded to a boat deck that is designed for the dynamic loads. With only four containers, I wouldn't even dock/undock the ships; keep them continuously moving, and pick and place the containers dynamically as the boats move through canal lock style controlled conditions. There are Twistloc designs that are purpose-built to automatically work with the container cranes with no manual intervention.

The idea is impractical because the fast turnaround is not going to offset the overhead of a separate boat per 4 containers. People usually don't think of container ships, but they're bean-counter-efficient designs, and the boat overhead costs per container are absurdly low.

We're at multi-year highs now nearly touching $2590 USD per FEU Asia-West Coast on the spot market, maybe around $4-5K if you're doing a one-off by your lonesome through a freight forwarder [1]. But the opex cost per TEU per day for the larger container ships is around the $10 USD zone [2].

Using super slow steaming numbers, which would be comparable to sailing vessels' time, we're likely looking at 15-20 days for that Pacific voyage. Say 20 days to be generous to the case of the autonomous boats, so the opex cost for that voyage works out to about $400 USD per FEU. Amortized capex works out to maybe another $500 USD per FEU in normal economic conditions, plus overhead for maintenance (the ocean is a real PITA), plus some profit off the top?

Whatever that capex really is, building and financing those autonomous 4-container boats have to squeeze into about that budget, plus whatever of the opex they can skim over for not having to pay for bunker fuel (which is absurdly cheap, yay externalities) and crew (a fraction of the opex) [3]. I'd probably look into vanadium redox or iron batteries, since I'd want to amortize out way longer than say a Panamax does. Everything that touches the phrase "marine-grade" gets magic 10X cost pixie dust sprinkled on it giving the bean-counters who buy the stuff micro-strokes every day (bean-counters on the other side of the sale get hookers and blow, there's gonna be a Nobel for the person who figures out how to replace 304 grade stainless with something as cheap as pig iron and just as workable), so I find it hard to see how the numbers pencil out wrapping lots of ship around so few containers, until the global economy radically changes to a form we don't recognize today.

One last thing: sails at scale are freaking hard to recycle. These days with sails mostly relegated to recreational markets, there is sufficient demand for the bags and other stuff they make out of used sails. I think the Dacron-based remnants that is in tatters can be sent into PET recycling streams, but the more exotic stuff is going to be more challenging like windmill blades. Commercial quantities of beaten sails would be an interesting problem to solve.

Twitter doesn't let you disable SMS verification so that's their answer. :/
Huh, thanks, I think I’m starting to get it. Is it that the connection-based model needs the data “copied” into each user’s stream on the server-side while the “stash the files in a bin” stateless model allows the networking hardware to cache this data somewhere in memory and just copy it on the fly onto different network links?
This is interesting.

Not sure about the economics of this though. Sailing seems like slow way of transport and may have higher cost because of more human crew. Why would any business opt for this service unless there are no alternatives? Am I missing something here?

But I see the appeal as a tourists. I would love to travel in one of these beauties.

I'm sorry to hear that. Every situation is different. If I were in your shoes I'd try to be open about it with recruiters and figure out / propose some alternative that work better for you - whatever that might be. Also keeping good portfolio of Open Source projects, blogposts etc. might help convince potential employers that you're worth considering and that your 'condition' (for a lack of a better word) is real and does not affect your work performance. Keeping good reputation and connections (which you already mentioned) is also very important.

From my experience companies are very flexible and open minded - mostly they care about just not hiring someone that they will have to fire later.
I wonder how Pine64 is going to handle the new HongKong situation, it dissolved its company in California[1] last year due to 'Legal Mafia' and re-established it in HongKong. The website claims to operate under China & Malaysia laws[2].

Irrespective of HongKong situation, it was already tough to receive pre-built smartphone shipped from China in India without paying extraordinary import taxes; Now due to China goods blockade there's no way I'll be able to receive this PinePhone and I'm very sad for it.

I hope Pine64 starts shipping from their Malaysia front(Which seems to be office of their Chinese manufacturer - Syabas Technology[3]). I really want these pure Linux phones to succeed, I'm tired of this duopoly in the smartphone ecosystem as a consumer, developer and as an entrepreneur.

I agree, it wouldn't be problematic, but it seems like a world-scale prisoner's dilemma, that goes back at least to the time of the dawn of agriculture. All it takes is one culture to defect, and they will "win" - so how could you possibly disincentivize that?
Is your garage actively ventilated? Mine (in my previous house, I live in an apartment now) was a closed room with a pulldown door (always closed) and a window that didn't open. It's not hermetically sealed, but how confident are you it wouldn't become saturated with N2 gas?
Yeah, I wasn't clear; I'm terribly sorry.

Let me circle back and invite you to make sure you know all the limitations of being common law partners (which you seem to be). For my wife and I for example, the fear that her parents might have the final say in her health decisions if she's incapacitated meant we needed more than simply common law.
Given the speed with which I had charging problems, it surprises me that I don't hear more people complaining about it. The metal contacts inside the case of mine don't seem to protrude enough. I can usually get it to work again with a q-tip... but not by cleaning. I kind of put it down and swirl it around until it catches on the metal and pulls them out again a bit. Without that, no amount of jiggling or pressing will get charging contact. Then it happens again a few days later. The right side started doing it first. The left one followed a few months later.

But, i just had my own 'rattlegate' around the time of this post, and apple replaced the case under warranty for me with the bad pod, at least.
In France they give nicotine patch to nurses because they discovered, to their horror, that smokers are heavily under represented in critical cases. Something to do with nicotine.

They're annoyed because that would be like asking people to eat raw sugar to stop drinking Coca Cola, but I'm not yet stopping my cigarets :D
They should be using things like yubikey though, not phones
you can certainly cite the multitudes of factors working against staying healthy in todays modern environment, and those are super valid and should be considered. However, ULTIMATELY nobody can force you to be healthy and bar getting rid of any possibility of anyone obtaining "unhealthy" food, the responsibility in the end lies with the individual in most cases.

Indeed. As the old saying goes, Al Capone got nailed on tax evasion. As I understand it, the IRS is more interested in the amount than where it came from.
They are just as likely to catch it, but the symtoms are less severe in more cases than non-smoker.

You need to stop thinking identity singular, and identity as valuable. Have many and treat them as disposable. Of course you can't do this on the 2020 web that consists of four websites filled with screenshots of each other, but that's just one of the many reasons to burn those websites to the ground and resist any attempts to remake them. And it turns out your parents were right about not using your real name on the Internet. Social media and their consequences have been a disaster for the human race.

That seems unlikely. The scale of the attack and the profile of the accounts just doesn't seem to me that would be the case.

Currently their earned BTC balance is $120k+ for comparison. That's a pretty successful scam and 5% of potential revenue will not make anyone go white hat.
I have a question to ask you all. If I wanted to study things to get to the point where internally/externally I could coordinate a hack of this magnitude, what things do I need to study? What are the technical things needed to pull something like this off? What are the social corporate things I needed to know to pull this off? I know that we don't have specifics, but I'm asking as a pure academic exercise how much I'd need to know to pull this off, and how to get away with it too.
