You won't forget the names when it matters.

If you can't remember these basic details, it's a sign that person is not close enough to you for it to actually matter.

Or, maybe you're like me and you just met the person five minutes ago. Either case is forgivable.
That's just a slab allocator. They're not what I'd call trivial, but still simple enough to be common in small projects and CS homework. I agree that an array is still generally simpler though.

Nice try, but this "$1.3B Startup" is nothing more than a glorified UI on top of email. I wonder how they will justify their valuation in this crowded market.

And this article at this timing (on the same day Slack was acquired) is clearly a marketing article for this company.

They should have just owned it and said "come use our service instead of slack, now that slack is acquired", instead of throwing around the cringe worthy hype words like "slackifying email"

This news is the death of EMRFS. The only thing it has left is fast listings of "directories" using DynamoDB.
Someone will probably need to correct me, but here's how I understand it.

Proteins naturally fold into a shape where they have the lowest "potential energy". There are several useful metaphors to explain what "lowest potential energy" means and why the proteins are attracted to the shape with the lowest potential energy.

In "the real world", an object's "altitude" is a form of potential energy. A ball on a hill will roll down hill until it settles into the lowest valley it can — the place where its potential energy is lowest. Balls roll downhill to the place of lowest potential energy, and proteins fold into the shape in which they contain the lowest potential energy.

You can also think of a fresh protein as a stretched out spring. The stresses in the spring from being stretched out of shape are a form of potential energy. The spring will contract until it is completely relaxed so there is the minimum amount of "springy" potential energy remaining. Springs contract into the shape that is most "relaxed" and has the lowest potential energy, and proteins fold into a shape having the lowest potential energy.

If the protein was to fold into any other shape, there would still be some potential energy left in the protein that could be relieved if only the protein could get itself folded into the "correct" shape. If the rolling ball gets stuck on a rock or the spring gets snagged and can't completely relax, both objects would be stuck with a higher potential energy than they would if the ball reached the bottom of the hill or if the spring were allowed to fully relax.

Hopefully this explains why there is a single shape that proteins are most attracted to when folding. But, it doesn't explain why other shapes are somehow "invalid".

Proteins are like pieces of cellular or chemical "machinery". Like the parts of a mechanical machine, the protein's shape is part of what defines how the protein works, what it can "do", and how it fits together with other pieces of the cellular machine. And, since "correctly" folded proteins always have the same shape, "machines" can be built with them.

When proteins are misfolded, they have a different shape from the shape that all of the other machinery expects. Like a gear without teeth cut into it, the misfolded protein doesn't perform the function that it, as part of a cellular machine, is supposed to perform. The protein might "jam" the machine up or even cause the machine to malfunction and start doing something completely unintended.

I hope this comment is correct enough and clear enough for an ELI5 — though it might be more of an ELI15.
Well in a post scarcity society, the janitor is a roomba.

When nothing needs to be done, you can spend all your time working on things you want to work on, or just sit back and relax if you don't feel like working on anything at all. The only way you become king of the mops is if you are weirdly into that sort of thing.

Even if the array overflows the cache, it's not too bad for most access patterns. CPUs will easily prefetch data on a linear scan, so the "second half of the array" will most definitely be in cache by the time you get there. And a linear scan-once shouldn't even evict too much other stuff out of the cache.

In practice, I would let benchmarks decide the array size. Modern CPUs are surprisingly good at prefetching even linked lists, and x86 works weird out-of-order magic and speculation while waiting for memory. My rules of two thumbs were 1) where performance really matters, don't trust your intuition, program and benchmark alternative implementations 2) don't trust microbenchmarks, e.g. total icache pressure changes whether inlining is good or not.

I used to take some yoga classes where the series of beginner poses was the same every class. I was told that this was to keep people feeling as if they themselves were always a beginner — our shared revelation here really reminds me that there is tremendous value in sometimes questioning the “sure things”!
> and not a penny of that increase went to the company.

I think they might have raised a bit / issued more shares since IPO (not sure)

Slightly different question: if the stock price increasing doesn't really gain the company any money, why are board executives typically concerned about share price performance? Obviously because they get paid in grants, but... are there any other reasons that actually benefit the company itself instead of the shareholders?
AmbraHealth | Senior Perl Engineer | REMOTE (in the US) | Full-Time | https://ambrahealth.com

AmbraHealth is modernizing medical care with our cloud-based image management suite. Demand for new medical solutions has increased during COVID. Come join our growing team and do meaningful work that has a direct and immediate contribution to patient care.

We’re looking to hire a few Senior Perl Engineers to work on the Ambra services API, a large-scale, Perl/Postgres/Redis application that sits at the center of the Ambra suite of products. This application provides REST endpoints that are responsible for providing control and access to all of the data (study, patient, image, etc) and it contains all of the business logic (authentication, permissions, associations, rules, etc) for workflows managing billions of medical images.

We are a permanently remote engineering team. We were pre-COVID and will continue to be be post-COVID.

Send resume and cover letter to mike+jobs@ambrahealth.com. Our hiring process includes an option to do a short, well paid, part time consulting project to determine if we’re the right place for you.
Sometimes it’s hard to be the kind of person we want to be for people we really care about.

One way of showing you care is making the effort to remember important things. Another is staying in contact. I’ve used Anki to remember friends kids names, and Monica to remind me to stay in touch. Very occasionally, I use Monica to remember where a friend is in their life last we spoke. Often a tiny cue is enough to jog your memory.

You might consider that “unauthentic”, but I would say people’s brains and memories are just really different —- what’s easy for you is not necessarily easy for everyone else. Using these tools let’s me be closer to the type of friend, brother, son that I’d like to be.

I should add, having moved overseas, Monica has also helped me maintain relationships with people who are very important to me, but who I may only get the chance to speak to every few weeks, or less. I’m quite grateful for it.
The need to return to a natural state is only in the event of a full divestment/closure of the site. If the site continues to operate in some fashion, it is not required to be restored. Also, if NSF divests the structure (essentially handing over all responsibility to some other party), I believe the new "owners" would also be bound by the need to restore.

However, neither of the above would prohibit a new replacement being constructed.

That being said, you're 100% correct. NSF is highly unlikely to fund the a new instrument. For a rather long time they've exhibited a distaste for Arecibo. Whoever it was that started NSF down this road back in 2006 must be quite happy with the results.

What's insane is how "affordable" a telescope can be compared to the things we casually build and destroy for military spending. Green Bank Telescope (105m telescope) was constructed for around 100 Million USD, and it's a moving telescope.

For the cost of a couple of F-35 jets, we could possibly build a new telescope, or make a rather large step in the right direction.

Listing and update consistency is great, but the ACID SQL-on-S3 frameworks (Apache Hudi, Dela Lake) also require atomic rename to support transactions.

HopsFS-S3 solves the ACID SQL-on-S3 problem discussed here on HN last week ( https://news.ycombinator.com/item?id=25149154 ) by adding a metadata layer over S3 and providing a POSIX-like HDFS API to clients. Operations like rename, mv, chown, chmod are metadata operations - rename is not copy and delete.

I would assume that civilization doesnt collapse like a building, it collapses like an ecosystem, slowly components of that civ don't have the resources to exists, services go unrendered,people stop living in that area, pressure builds on less affected areas.

"For example, if I bought you a gift for $100 and you thought that it was actually worth about $70 it would mean that, somewhere along the line, you’ve destroyed $30. Pop! It's gone. You might as well have just taken your cash and burnt it."

I would argue that in that case you have actually given a great gift. They have gotten something they consider valuable considering the $70 amount they would pay for it but a bit too much of a luxury given the fact that it actually costs $100.

$1M should provide you some $30-40k a year in perpetuity. That's actually pretty decent retirement money in most parts of the world, somewhere in the top few percent of the world population by income.

But of course, $2M would be better, provide more buffer against the uncertainty and allow you to retire even in the US.

It is not the location it is the culture. And the commerical part to it. (Not just politics, china is state capitalism if you want a short name) no money no er and I do not follow up to set up a tourist town next door or perhaps collapse in current env.

Then politics will play a part, not because of its being communist but once again its way of doing business. Russia work a bit with USA on aerospace area. What China does so far other than national glory? Have putting instrument on the moon and collect moon soil work with others. How? What is the catch?

Still waiting for the largest collider to be discussed. But then all business and politics (as business).

It might be the next world power. But it would not be another USA or Soviet Union. Or Russia foe that matter.

History is not kind to chinese and china. Hope it is better for the humanity.

Last time I check it is the problem to have those old things there.

Like you I initially think just a repair job. Big one no though. But it seems those remaining could harm anyone who do the repair. It was not designed with only one less cable. And hence those remained can cut anytime and anywhere. The whole area could be a danger Zone.

Seems you need to demolish the whole site if the discussion along this line is true.

See whether any better information. But I guess the reason why the maintenance is not there to prevent it is also the reason it cannot be rebuilt.

The "evidence" is two blocks, with the same block height, both signed by the attacker.

Not sure what these two versions of the blockchain you're talking about are. Signing two blocks at the same height with the same chain id is the slashable offense. It doesn't matter what's in them.

If the attacker wants to have his own blockchain off in the corner where he has all the money, nobody cares.

Program Counter = Counter used for programs. Counts bytes for position of next instruction.

> Slack is best when you are just a drone on a project/channel (if that makes sense...).

> Slack also is great when the conversation is heavily one sided.

Honestly, that seems extremely unfair to me. It feels like you're using it wrong. In my experience, Slack is for conversations. The groups I'm in use it for tossing out random thoughts/questions... and people participate as they choose.

If you're using in a way where people are constantly pinging you demanding your attention, then you should change that. That's no different than being in a large office and everyone else feeling free to just walk over to you and tap you on the shoulder every time they want something. If _that_ was happening, it would be something you should fix, too.
The Amiga has never been multi cored. Has Vampire accelerators to replace the 68K chips and PowerPC upgrade cards.

Apple in making the M1 Chip is using some of the Amiga IP circa 1985 that speed up the system where the CPU and GPU etc. share memory. Amiga is shattered into different companies, but if they didn't go out of business they would have made a M1 type chip for their Amiga brand.

I am not sure this is true. It is prohibitively expensive to read from all replicas. All you need to ensure is that any replica has the latest state. See how Azure Storage does it [0]. Another example is Spanner [1] that uses timestamps and not consensus for consistent reads.

Just out of curiosity: the press releases I've seen about these big government players switching to Matrix generally mention that they're using a customized client of some sort. That's understandable, but what I want to know is: Have they also customized the underlying protocol by which their homeservers communicate?

The reason I ask is that it seems to me (as an entirely uneducated outsider) that if they're using the Matrix protocol as-is, then they have incentive to support and assist with the further development of the Matrix protocol, which is great. But if they've already started customizing it, then I would worry that they eventually will decide they don't need Element or the main Matrix protocol and will just go off and do their own thing.
