The stock went up 8% on the day of the announcement, giving him a gain of under 400K pretax. This is a lot of money for mere mortals like us, but small potatoes for the CEO of a major multinational company.

I find hard to believe he would risk an insider trading lawsuit over this amount, so my conclusion is that this was simply a prescheduled transaction. Have in mind that the increase will stick around for some time (stock still up ~8% since last week) so he would have benefitted anyway selling many days afterwards, or even weeks.
> The M1's memory is LPDDR4X-4266 or LPDDR5-5500 (depending on the model, I guess?) which is about double the frequency of the memory in the Intel Macs.

That's a high frequency, but having two LPDDR chips means at most you have 64 bits being transmitted at a time, right? Intel macs (at least the one I checked), along with most x86 laptops and desktops, transfer 128 bits at a time.

> Apparently, this alone seems to account for a lot of the M1's perf wins — see e.g. the explanation under "Geekbench, Single-Core" here

That's a vague and general statement that site always says, so I wouldn't put much stock into it.

don't MacBook mysteriously run slower if you plug in power on the left side instead of the right? I don't remember the cause but I've personally experienced this handedness issue on my mac
Many things are unclear. There's so much confusion right now.

- Will they ship a more advanced spec for the upper line? Something like a M1x, thus replacing the need for a third-party discrete GPU?

- Will they market these devices like they do with the iPhone: same Soc for every generation but with different sizes/extras (Macbook Air, Pro, Mac Mini just like you choose between an iPhone Mini, Pro, Max)?

- How long Intel-based machines will still be around? What they will do with the Mac Pro?

- How smooth will be the transition with OS/software (I expect it will take more than the two year planned) and how much it will change with this new ARM ecosystem?

As with any new first generation device from Apple, plus this vast, unknown land, I'd stay away from these machines and wait for at the least the next iteration (maybe two).
Yes, based on my experience on a mac, I would not buy any mac with less than 32gb ram (I personally use 64gb and it's so much nicer)...

Yes, it seems crazy, yes it's a lot of ram, but I like to be able to run VMs locally and not have to boot up instances on AWS (insert provider of choice), I like to keep tabs open in my browsers, I like not to have to close apps when I'm using them and I like my computer to be snappy. 64 GB allows that 16 doesn't, 32 barely does.
No. I think all publishing disciplines seeking grants and tenure tend to the same outcome (not an academic, worked in university research and general staff many years ago in 3 UK and one Australian uni)
Makes perfect sense to me, even as a mostly-Python developer with very limited experience in .NET/C# or other ecosystems.
I'm very confused about the overall attitude and trends at the moment when it comes to higher education especially postgraduate education and academia. On one hand there seems to be a certain amount of disillusionment with universities, degrees, getting a PhD and working in academia. At the same time the education requirements for jobs seem to be inflated and way more jobs require an MSc or a PhD these days.

By the way, the article is from 2013.

The problem I see is that scientists make so little money it is very tempting for them to accept indecent offers like "We pay you X if your study about Y finds Z". I observed this mostly when it comes to studies about cannabis as there was a big push to discredit the plant as a valid medicine and an alternative to "regular" medication.
What a bizarre suggestion.

People working from home save their employers money through reduced need for space, services and consumables at offices or other business premises.

They make lesser demands of public facilities, notably reducing the load on overcrowded transport infrastructure and so improving efficiency, the environment and, particularly at the current time, the health and safety of those who do still need to travel.

They support local businesses in the areas around their homes.

Their own quality of life may be qualitatively improved, not least by getting back several hours every week that is no longer wasted on commuting. This has obvious benefits including greater personal productivity, better mental health and providing more family time for parents and children during the week.

And as a secondary benefit, forcing businesses to accept more remote working might undermine long-standing toxic practices and presenteeism culture imposed by bad management, further improving both business productivity and personal quality of life for many.

We shouldn't be taxing working from home (or working closer to home instead of in distant facilities). If anything, we should be incentivizing this shift in our way of life, and we should be adapting our planning and infrastructure policies to support doing more of it in the future for those who can and want to. That could mean anything from just allowing more small business premises within predominantly residential areas where their services are likely to be needed right up to creating local business hubs where people can set up to work, access shared facilities and enjoy some personal contact if they don't have good facilities to work literally at their own home or they prefer a more social work environment.

We're definitely going to have some big bills to pay after the coronavirus problem has been mitigated, but I can think of a lot of more reasonable ways to generate extra revenue on the required scale than this. How about some real international collaboration to establish transaction taxes on multinationals that make huge amounts of money largely by moving money and/or personal data around with little evidence of any wider societal benefit from their activities, for a start?
Thanks! Sharing is definitely no. 1 priority and would be a great feature.
Newly discovered primate in Myanmar 'already facing extinction'
No danger? It seems a very precarious position over the next five to ten years. If Apple find success with their strategy, then money is going to flow into the development of ARM chips from Microsoft, Amazon, Google, Nvidia, etc for their own products/servers.
He, infamously, wrote these notes realtime in lectures.
Rumour has it doing a PhD might actually be a rewarding experience in its own right, and not derive its value solely from the possibility of remaining in academia.
> It's ok for Apple to also make computers for people that are not you.

Yes, it's perfectly fine to sell machines like these with specs from 2012 but their efficiency should be reflected in the price. Honestly, what Apple is doing now seems like pushing power users buing new hardware towards non-macOS systems.
But they would know that going in.

My parents are both PHDs in physics and professors etc, but I knew 15 years ago how hard it would be get a decent job in the field and didn’t pursue sciences.

So I don’t really have much sympathy for grad students who complain about having lack of opportunities.
No. In other words, controlled or monitored physical access.

If I have access to a keyboard connected to CPU, that's a form of "physical access." IO devices are part of the computer.
I wonder if what you're observing is the result of stronger commercialization in the US.

In Europe, my impression was that most "dates" are just hiking or bicycling together, or cooking together, or in university you'd study together.

For a cooking date, of course one has to buy slightly more ingredients. But I would have been very upset if you would call that "spending money on a woman [..] in hopes of sex" or "a polite form of prostitution", because I'll usually share my food if I have visitors, no matter which gender or intention.

My opinion is that most of the dating that you see in movies is quite impractical, because all of it prevents an honest and intimate discussion. Plus I don't know any couples who met that way.

Shopping? Noisy, crowded, too many distractions.

Cinema? It's either too noisy, or everyone else will hate you for talking.

Restaurant? Why make things unnecessarily awkward by having a private discussion in front of 20 strangers?

In short, my impression was that the woman sizing up the man if he will be a good provider only happens after the blossoming relationship is already working on a sexual level. And I'd say that is reasonable and not offensive. If you plan to move in together or want to have kids in the future, you'll want to have a teammate that can support you.
I worked as a part-time lecturer for one course, over two years, and I did it for the love of it, because I had to take time off my high-paying contract to do it, and it cost me thousands to do it. I don't regret it, and quite enjoyed it, but I was appalled at the state of academia and how poorly resourced it was, despite the vast amount of money being charged the students. Permanent staff were few, and I don't really understand how academia is designed for anyone but those at the top. The article's basic point is right.
This is not how I make notes. This is way beyond my note-taking skills and I cannot say anything else than I am deeply impressed!

High quality notes is of highest value to yourself, or others, as has been proven many times before. My favourite example is the notes taken by Marcel Grossmann, used by Albert Einstein.
Yes, but the OP wants less pay for less work which is fair but not an option at lots of tech companies.

So you either play the overwork game or don't get to play at all. That's all part of the golden handcuffs routine, along with stock holdings etc. Give your life to the company or bugger off, no middle ground.

That's why I wanted to point out that it's entirely reasonable. It's just a different work/life weighting, people should be able to still work in tech and not have an 80/hr week.

I'm more partial to the idea that a metabolic system to harness energy had to develop before replication and that life started in alkaline hydrothermal vents rather than ponds due to the delivery of energy and concentration of chemicals. Really enjoyed Nick Lane's writing on this topic, highly recommend his books.

I would be very impressed if this works with actively scraping hostile sites like LinkedIn, there are not much detail on the site about how this works.
> It doesn't make sense for the system not to 'grab' a big chunk of your RAM. That is what it is there for. You want stuff to be preloaded into RAM so you can access it quickly if needed. You only want to leave some of it free so that if you launch a new application it has breathing room.

Cache is excluded from just about any tool that shows RAM use, at least on desktops. If the ram shows as in use, the default assumption should be that it's in active use and/or wasted, not cache/preloading.

> For example Chrome will scale the amount of RAM it reserves based on how much you have available.

Which features are you thinking about that reserve ram, specifically? The only thing I can think of offhand that looks at your system memory is tab killing, and that feature is very bad at letting go of memory until it's already causing problems.
Every IDE I've ever tried is slow. That's literally it for me. I do use VS Code quite a bit for more complex refactorings, but I do use vim for quick edits to files + initial development.

Edit: should say, I also do a lot of work on remote Linux boxes, often supercomputers. Vim is the only thing I can guarantee is installed - Emacs often is not.
I like that idea. Whether or not it's viable depends a lot on user-friendliness and your ability to attract users.
Time series databases and Kafka are intended for very different workloads.

Kafka is used as distributed message queue. I.e. a set of apps produce opaque messages and send them to Kafka queues, while another set of apps consume these messages from Kafka queues.

Time series databases are used for storing and querying time series data. There are no Kafka-like queues in time series databases. Every time series has a key, which uniquely identifies this time series, and a set of (timestamp, value) tuples usually ordered by timestamp. Time series key is usually composed of a name plus a set of ("key"=>"value") labels. These labels are used for filtering and grouping of time series data during queries. There are various time series databases optimized for various workloads. For example, VictoriaMetrics [1] is optimized for monitoring and observability of IT infrastructure, app-level metrics, industrial telemetry and other IoT cases.

As you can see, there is little sense in comparing Kafka with time series databases :)

There are people whose wealth on paper grow that much. Maybe they are counting that as income?
It's much more complicated when other risks are involved. It's like someone sold you a bun by labeling it as gluten-free, but it was not. Maybe you're just slightly intolerant and nothing lasting happened to you, but you could still sue them.

Unlike that example, it's difficult to know if there were direct damages, but some big companies can come together and try to make a case and sue them and demand huge compensations. Zoom could have spied on your conversations and sold your information to competitors even though they sold the product claiming that they couldn't.
As i suggested elsewhere, men should retain both children and money after divorce; women should get nothing given their behavior. It is also more biologically correct as man can find a younger partner and still have more children.
What Is the Purpose of Private?
How many exploits are made unreasonably hard just by making the executable code execute-only?

Also, what about making syscall table something that is passed to each process on start - containing syscalls in random order?

I largely don't care about the current reality of things. Having fixed system call numbers, fixed function order, merged text and rodata - all these things just make me tired and want to start over with the whole thing.

Also, is nobody concerned that JIT is normalizing creating new executable code at run-time?
Exactly - I'd guess the majority of Macbook Airs are used for surfing, email, writing a presentation etc. not developing.
What, you want to ascribe value to learning itself? But it's so hard to measure! Simpler then to ignore it and use lifetime wages as the only relevant measure.

Apple single thread performance up 198% vs Intel 28% last 5 years
"Whilst in the past 5 years Intel has managed to increase their best single-thread performance by about 28%, Apple has managed to improve their designs by 198%, or 2.98x (let’s call it 3x) the performance of the Apple A9 of late 2015.

Apple’s performance trajectory and unquestioned execution over these years is what has made Apple Silicon a reality today. Anybody looking at the absurdness of that graph will realise that there simply was no other choice but for Apple to ditch Intel and x86 in favour of their own in-house microarchitecture – staying par for the course would have meant stagnation and worse consumer products."
SpaceX ready to take four astronauts to ISS Saturday
As it turns out, you can build most distributed protocols on top of an API which only allows you to append to and read from a shared log -- for example, if you want to do consensus across a number of actors, you can just have each one write their proposed value and the current epoch to the log, and the value that is written into the earliest log slot wins. In general, shared total orderings are equivalent to consensus -- this is clear when you consider that State Machine Replication (Paxos, Raft) is all about ensuring that all actors perform the same set of commands in the same order. If you're looking for a more detailed exposition of the shared log abstraction and its uses, you might benefit from reading the Corfu (https://www.cs.yale.edu/homes/mahesh/papers/corfumain-final....), Tango (http://www.cs.cornell.edu/~taozou/sosp13/tangososp.pdf), and FuzzyLog (https://www.usenix.org/system/files/osdi18-lockerman.pdf) papers from the lead author that precede this one.

"of graduating PhD students wish to continue to work in academia"

I'd be interested in the number who think they want to work in academia at the start of their PhD and compare this with the number at the end - I certainly went completely off the idea, not so much because I thought getting a job would be difficult but that I really didn't like what academic research encourages.

Mind you a pyramidal "up or out" structure can be found in areas like law - relatively few lawyers will make partner or even want to take on what that involves.
on a laptop, the cost of the additional ram is not marginal on power consumption, so it's not only a matter of $.

I use KDE and I have this problem. Similarly when I switch vterms (I have separate X11-Sessions for my personal and my work-from-home user account), I can briefly see the content of the session that I switched away from (without having locked it) before the lockscreen comes up.
This is the crux of the problem. Elites are going to represent the elites' problems and serve their incentives.

Social media induced "doom scrolling" almost needs a Surgeon General warning like nicotine packaging.
and if you think you can just build the package and get the correct hash from the error message, you're mistaken

Actually, you can. In any place a SHA256 hash is required, you can put *lib.fakeSha256" (which is an all-zeros hash) and the build will fail and Nix will tell you what the correct hash is.
Uh, if the syscalls are in random order how would your code know how to reach the proper one?

If there is identifying meta-data (such as names) associated with each then I guess malicious code can parse that too, or steal it from some authorized source after that has parsed it, or whatever.

On the other hand, I s*ck at security so perhaps this is the best idea ever ... honest question.
Apple made it so that you need their blessing to swap out the battery, display, or camera on their phones[1]. And they can't replace the battery on my MBP but have to replace the whole top case, nor replace the little rubber feet without replacing the whole bottom case.

At this point ascribing any sort of "it's just the economics" reasoning to Apple is wishful thinking. They're doing this on purpose.

I love these stories about hacking around hardware to enable features in the software. I'm impressed when seeing engineering decisions of leaving ways to upgrade boards to the next level of options.

It's a good series of articles to read, they show good technique in how to do the reverse engineering process.
Here's the deal, since this issue comes up regularly in Hacker News comments:

It is 'not illegal' to time an announcement to benefit yourself if you have a 10b5-1 plan in place that automatically sells your stock on a fixed schedule. It's 'not illegal' in the sense that as long as you don't admit you did it, there's really no way to prove it and there's no legal framework for prosecuting you anyway. Lawyers call it 'disclosure timing' and it's one of those often-whispered-about loopholes for the rich.

No one admits to disclosure timing, but we all know that it is happening. We know this because on average trades made under 10b5-1 plans get better returns than trades not made under those plans. [1]

The law is full of ways for rich people to get richer if they have good lawyers. This is one of them. There's not much incentive to change it either - it is hard to prove, it is complex to explain to the public, and the kinds of people that benefit from it are the kinds of people in power.

One of the suggested routes to make the market more fair is to require those with 10b5-1 plans to make their scheduled trade dates public. This would at least give the market at way to guess at disclosure timing too. But again, there's no real political incentive to do this right now.

Yes, because a 25 year old has the same maturity and life experience as a 40 year old (or similar age numbers). How dare the young make decisions that from the point of view of someone with much more experience looks silly?

Also, the assumption is faulty that brains are like computers and processing identical information using a non-diseased fully functioning brain should obviously give the same result regardless of age.
Due to my son's love of Stellaris I became quite acquainted with Paradox's games, to the extent of attending three PDXCons so far.
