Incremental Innovation Is Great Until It Harms Your Business
My repetition of reading and listening is a response to your suggestion that shouting into the void creates echo chambers and what I interpreted as your fixation on being heard rather than listening.

Instead of shouting into the void you could cross it to the places mentioned in the article and provide them viewership while diversifying your perspective.
I'm not sure what value you think your point has, especially as the OP wasn't attempting to detail their entire medical history.

Yes it could just disappear, but for some migraines are a chronic issue and the meds for it are preventative and not a cure.

I'm not sure if you've dealt with chronic illnesses but I can tell you from experience that a lot of us regularly attempt to come off our meds to see if anything has changed 'underneath' the drugs, as often the drugs have other side effects that make it hard to tell what's really going on.

It's highly likely then that the OP has indeed tested to see whether their migraines have just gone.

It's also odd when people defiantly state that we don't make medical decisions based on anecdotes when clearly all medical decisions were once anecdotes that were then tested for efficacy and became best practice.

The most clear recent example of medicine catching up with annecdoatal evodence for me is severe epileptic using diet manipulation to manage their condition when prescription medicine did little to nothing as a preventative.
I've written some memory allocators that use lock-free allocation maps. In this case, a 4kb granularity allocator that used compressed free-bitmaps for usage in both userspace and kernelspace.

The entire thing was lock-free, so allocations would never stall on a lock, even if the allocator had to decompress a bitmap (the way compression worked was by looking for free memory ranges and then replacing them by a range expression, which saved a few MB of memory per Gigabyte of memory available, as well as ordering largely free memory blocks to the start of the bitmap list to reduce seek time). Despite the complexity in the allocator, it could serve any number of threads without ever locking up. The worst case was a long latency if a thread had to scan the entire free list for a free block (It would switch to a different allocation behaviour if a thread had more than a dozen failed allocation attempts).

A bunch of ring buffers I've worked with are atomic (ie, lock free), probably the most common application of lock-free stuff.
Question: how do you guys structure this at DO?
Hm, in c++ there are a fair amount of battle-tested, permissively-licensed lockfree containers though

The comment I replied to was suggesting doing these panels as part of donating blood as an added incentive, but was worried that people would intentionally donate while unhealthy in order to receive free lab work.

I said that isn't a problem places where medical lab work already has no cost, as no one would be incentivized to donate blood just to receive lab work.

Not sure where this got lost along the way since this is one of two comments effectively replying to the same misunderstanding.

I gotta say, it always makes me furious whenever I see "Facebook and Instagram".

You often don't know (or want to have to think about) what message is "special" at the time. I've gotten useful value from searching years-old email, and years-old text messages. Text messages are small and easy to save, and I expect device storage to grow far faster than the size of every text I've ever sent or received.
Zstd compression with configurable levels is really interesting: You could write every block first with a level comparable to lz4 for very fast performance. And if a block has not been rewritten for some time you recompress them with a compression level allowing more compression and comparable decompression performance.

So cold data (cold write, cold/hot read) will take less and less space over time while still having the same read performance.
AWS launches EC2 computing instances that run Apple's macOS operating system
Expo.io is good enough for my needs. Cross platform, just run it on my iPhone and and android simulator. Also, the way expo works is that not all updates need to go through the App Store approvals. I can quickly dev/test/release once I have the app container approved by the relevant store.

So they have 'co-processors', like the Amiga, but on a chip!

Recall, this is what made the Amiga such a groundbreaking computer back in the 80s and early 90s: separate co-processors that handled graphics, sound, DMA, IO,...

It worked (for a while) because the Amiga was an integrated system of hardware-and-OS - exactly like Apple. Unlike the MS-DOS and Windows PCs of the time, there was no need to support third-party hardware.

Together with a really nice OS, the platform encouraged creativity and gave rise to a generation of coders, artists, and musicians.

So everyone: now you know what it felt like when the Amiga first appeared on the home computing scene!

The obvious side effect of selling more Macs is that it hurts AWS and MacStadium's competitors. Developers don't want to buy more Macs from Apple that they don't need. Apple knows this and has known this for decades and so their actions are essentially the same as telling developers to suck it up and buy new Macs.

Build a fusor running roughly at 10kV (Microwave transformers can do that if you modify them a bit, otherwise starter transformers from light fixtures or your car may be able to handle it).

That'll get you in the temperature range. You can also up the voltage to get more exciting effects, fusion is fairly easy to achieve here. Just not net positive fusion.

Ask HN: How to Start a Developer Blog?
I've been reading developer blogs from a long time and was a consumer. I'm trying to break out of this habit and start a blog before 2021.

I don't want to be something fancy, I just want to setup it easily. If I should go with blogging platforms like Medium or Dev.to. Or should I look up for static site generators like Gatsby.

PS: What advice would you give to someone starting a blog?
That's the science-snobby way of dismissing it.
I orderered up some 2000IU vitamin D3 from CostCo for my elderly Dad in May. He's pretty much housebound at the moment with underlying health conditions, so I figured it couldn't hurt and might help.
GitHub Actions, which is mostly a copy of Pipelines, has Big Sur while Pipelines doesn’t.

Someone points out Circle let’s you ssh in, while afaik GHA and Pipelines don’t. Is this a key difference?
Don’t get me wrong I get that many companies do this and it’s the industry norm when it comes to enterprise sales but on average I think the incentive structure leads to a number of issues and sure there can be stand out sales folks that aren’t selling but really aligning with the customer, but can’t go based on exceptions, have to look at the average sales person to see what kind of an individual that incentive structure creates.

I also think you can augment the customer success team to take care of that especially if you have a wide variety of customer profiles.

There is massive potential inside of companies customer support organizations that go unrealized.

They know the product, the customers, the bugs, they are the front line for down time, or bad deploys by engineering. I think the sales model is an old model that will eventually get up ended.

Customer Support > customer success > inbound leads

And if you do customer success right the customer will naturally grow with you or you find the limitations of the platform and that’s critical product feedback.

Btw, your description of a great sales person also works equally well for a great customer success individual.
Obsolete on Arrival is what's implied i think. If deuterium–tritium fusion experiments start sometime after 2035 then it's potentially "ancient tech" given the accelerating tech timelines (singularity) which is exponential in character.
SpaceX's innovation was looking at the market and deciding that Iridium was right but about two decades too early. A lot of people in the industry (and a number of governments as well) lost big when Iridium went bankrupt, and quite understandably the large players were content to stay in their lane. After all, ULA came about basically because the DoD needed two technologically diverse launch platforms, but wasn't willing to commit to the launch cadence needed to keep both commercially viable under separate parent companies. If there hadn't been a future with customers ready to fly, and launching enough to survive a couple launch failures, SpaceX just would have been the upstart with high insurance costs.

Hardware-wise, SpaceX did a great job gathering the best of what had already been done and proven. Friction stir welding? Used to build Delta II, Delta IV, Atlas V, Space Shuttle tank and more. Pintle injectors? Lunar Excursion Module. Semi-balloon tanks? Proven on Atlas I and II, and Centaur. Then, once they had something that flew, and a contract from NASA to keep it flying, they iterated on it to make it reusable. Much like the story of Boeing with the KC-135 and 707, a key early contract was enough to support the program and subsidize further development.
Yeah, still experimental but improved over 20.04. Added encryption and "autotrim=on" by default.

I think the game may have to change a few times already before a Dyson swarm (or even a significant fraction of one) could be built. We're going to need cheap clean power in large quantities to even think about manufacturing something like that.

It's not about syntax and language, it's about environment.

Compile 10 lines of hello_world.c into an ARM executable and send it to a friend using a 'walled garden' phone. It'll be useless to them even though it's technically correct.

Likewise the Web is being continually tightened and centralised. That HTML you wrote will soon require an HTTPS server, probably in a VPS because many ISPs block port 443. And the VPS provider has implemented a captcha in front to reduce botting, which links your visitor's data to another huge Internet corporation. Open web?
Errors are wrong.

Or, to put it more clearly: there are no errors, only conditions that you dislike. It's better to not burden your programming with your emotional shortcomings, and treat all conditions that you may encounter on an equal footing.

You try to open a file; the file may or may not exist, and both cases are equally likely and you get to decide what your program does in each case. No need to attach an emotionally charged label like "error" in one of the two cases of the conditional. Or worse, as some emotional fanatics do, to bend an otherwise clean programming language by adding features (e.g., exceptions) that help support your sentimental disposition.
If you aren't on UNIX, first you will need to find a graphics editor able to open PPM files, also an hurdle for beginners.
If you do not care about speed, you can get not arbitrary-precision (static number of significant digits, set upfront) but exact (dynamic number of significant digits, as large as you wish) results. Under the hood, your expressions will be directed acyclic graphs of lazy generators, each generator coresponding to a mathematical operation or function.

Here is a Python library that employs continued fractions to this end: [0]. You can pull successive partial quotients of the result from the root node of the dag. Whenever any node needs more precise input to deliver more precise output, it pulls a partial quotient from its argument(s).

I have no problem with MacStadium's business model; in fact, I have seriously considered renting Macs from them in the past specifically because of their service of providing a dedicated machine for an extended period of time. In that case we were looking at running extended builds and the cost of downloading Xcode, then our source tree, then running a build for hours on a per-hour service was fairly competitive with what was being offered by MacStadium. That we didn't choose it was mostly chance and external factors.

What Apple did here is create a monopoly for MacStadium, at least in the near future, and remove services like AWS from consideration completely. Brian's claims that they were simply offering their services in a way that "felt right with what Apple would have wanted" is marketing drivel. I don't care if I am getting a single core out of four, I'm not trying to browse Safari on this machine. Just run my builds and give me what I pay for; that's how CI works for literally everything else.

What level of having a foot in the door does this represent for Palantir? Presumably future extensions will be lower cost.

What forms of additional data trawling might we expect?
That is exactly what rankine is but it is not really widely used.
My original education is physicist and I worked as a scientist back in USSR. Then I immigrated to Canada and since I was not exactly Einstein science did not pay enough. So I've switched to product development since during my science days I've learned how to program computers, design mechanics and electronics for my experiments and many other interesting skills.

End result - been on my own for the last 20 years and develop products for living. From initial idea to successful production stage. Not always software. Sometimes it is also mechanics and electronics. Some I develop for my own company. Some I made for clients. Never had a single f.. up in regards to delivery and have very good references.

I do not get hung up on languages, technologies etc. To me those are just tools. What I am very good at is figuring out the most practical and fastest way to design build and deliver solid product. Sometimes I design and code most of it, sometimes I hire extra subcontractors. I get satisfaction from the end result and the pay of course. I've done just about anything from firmware and real time device control to enterprise systems for Telcos, etc.

So what do I call myself? No frigging idea but by word of mouth I get nice clients here and there.

Different place. Skin is big area and the vitamin gets relatively slowly transported to liver for storage. On the other hand, eaten D3 is absorbed very quickly with a fatty meal and you could obviously damage your liver with it.

For anyone not using Mac's, there's a few text-to-speech offerings online if you are ok with the privacy implications of sending that data to a 3rd party. Use it a lot for public conversational threads and mailing lists that I am expected to read but have low signal to noise ratios.

I'm not sure about what offline alternatives exist.
There's nothing contradictory in it. It may take several months to restore normal Vitamin D level from the state of deficiency, so it's very long process. On average much longer than typical Covid duration.

Proper Vitamin D level should be reached _before_ contact with the virus. Then the data would be valuable and helpful. Theirs data doesn't show much, imho.
> There are some restrictions if you're a man who has sex with men

This is a weird way of phrasing it. More accurate would be: You may not donate if you are a man who has sex with men. The only way to donate is to 1) stop having sex with other men and 2) wait 3 months.

I'd say "you can't donate blood if you're gay" is a pretty close approximation.
The thing that Stucki is celebrating can be summed up with this line from the blog post:

> I’m happy to have an absolute guideline from Apple

Before this, it was a legal grey area. Now at least the rules are spelled out and are clear. More importantly, they are the same for everyone. I think we could all argue over what the "right" limits might be (or if there should be any), but at least MacStadium, AWS, and whomever else wants to rent out cloud-based Macs now know where they stand.
Agree, but my needs are simple and I develop using expo.io. So once my app is published often minor changes can be pushed straight through to my app without App Store approvals. So it would be $26 per upload (ouch), but my “upload” may only be once every few months so I’d easily be ahead.
Intelligence and Investigation Talent Moves (November 2020)
It always depends on who's asking.

To my friends I'm a programmer, to someone in an official position (like a bank) I'm a software developer and to people I want to help out I'm a problem solver.

I never call myself an engineer as that's too broad to be useful. Some people who consider education to be the most important call me that, since I technically have a degree in civil engineering (civilingenjör in Swedish).
Laypersons often use the word "solution" in situations where an academic would say "method" or "approach": we did something useful, but it may not be the best possible way.

In pure math, "solution" means determining whether a logical statement is true or false. For example, in (asymptotic, worst-case) analysis of algorithms, the logical statements take the form "there exists an algorithm to compute X with asymptotic complexity O(f(n)), and no algorithm with lower complexity exists." These are crisp notions with no room for debate.

In this competition, they defined "solved" as achieving 90% accuracy. This is somewhere in between the two definitions. It's technically a valid problem statement, but it can become obsolete in a weird way. If someone else solves the problem of achieving 95% accuracy, then suddenly the 90% solution doesn't look so good. Compare to e.g. sorting. If we add the requirement of a stable sort, it becomes a new problem. Stable sorting algorithms are not automatically "better" than unstable ones.
Not at all, preprints are very important because the publishing process can take many months. In fast moving fields (e.g. COVID research) working with preprints is vital if you want to do cutting edge research.
