I brought a "portable" sawmill[1] a few years back, after doing a fair bit of research around this.

As I looked into it it seemed that there were some major caveats to making boards with a chainsaw. 1. It's slow, 2. One looses a lot of wood due to the chain kerf (thickness), 3. Regular chain sharpening is needed. On the other hand, it is pretty portable as this video shows.

I ended up going with the sawmill because it addressed these concerns. The downside being that one has to bring the logs to it. Cost wise it compared pretty equally to larger chainsaw mills I was looking at.

Having now used it for a coupe of years, my thoughts are:

0. It is amazing to see in action. I recommend watching the videos, but in person it is even better. It's the first think you need in order to become a Bond villain.

1. You need a lot of boards to cover a floor or a wall. It is hard work with my mill, and I wouldn't want to do it with a chainsaw.

2. It is surprisingly tiring (I find anything involving forestry is pretty hard on the body)

3. You will struggle to make a business out of it (I knew this going in, but just to reiterate)

4. Making straight lumber is a little tricky. Trying to do it is trees below 30cm in diameter is pointless. Making boards with a live (i.e. wiggly) edge is the sweet spot.

5. While I was super excited about this, it was actually the woodland mills wood chipper that was the better investment.

That all being said, it is amazing go fell a tree, then drag it over to the sawmill, cut it, then go and nail it up!

Sorry, I do get to remember to expand acronyms, but this one slipped through ;)
Actually news are saying that after the numbers get big enough.
Minor nitpick: the R0 is the basic reproduction number, it describes the infectivity if no measures are taken to control the spread.

You’re looking for R, the effective reproduction number, which is R0 plus all controls.
This is such weird phrasing. I imagine the corporate prison industry uses the same words: "She was also one of the pioneers of the fledgling private incarceration market. By creating this dynamic new industry, unlimited synergies can by unleashed within public-private partnerships".

I understand this is already possible with current tech. However not sure why we should empress to make it things even easier. Specially if the only thing that protects you if the absence of mandatory uploads of your daily hashed list. It seems super easy to switch that on.
We never stopped fighting in Iraq, so in what sense did we "win"? More to the point, we never left Saudi, which was the direct cause of 9/11, which also was not a win. Except, of course, for the armaments manufacturers. For them, 9/11 was most definitely a win.

"Serbia/Kosovo(ish)", whatever specifically is meant by that, is about like "Grenada" mentioned above. When you grasp at such tiny straws, you confirm the point rather than refute it: USA military exists to funnel money to weapons manufacturers and their employees in politics and media while killing mostly innocent, mostly brown people.

There are simulators for military aircraft. Falcon BMS simulates the F-16. DCS World has an entire collection of simulated aircraft. They come with manuals too. I don't know what actual pilots think of the accuracy of the simulation but they're clearly no ordinary video games.

Building Machine Learning Pipelines
They were able to measure a strong photoluminescence signal from the silicon germanium nanowires. Photoluminescence is a good proxy for how efficiently it will light up - carriers are generated optically with a light source more energetic than the bandgap of the material. This is much easier than fabricating a full device with electrical contacts.

Silicon is typically a really lousy photon emitter because it’s an indirect bandgap material. Turning an electron/hole pair into a photon requires an interaction with a phonon. It seems by getting the silicon to grow in a hexagonal orientation, it becomes a direct bandgap material leading to much higher emission efficiency.
The deductions given seems to be strictly based on the initial comment "anecdotal evidence".

But every change to the Cobol codebase carries a risk of introducing new bugs (and presumably there are changes if they employ programmers to work on it) so if a newer language and platform makes changes easier and less risky it could still be a win.
Transmission time isn’t really the main issue, it’s more about the work required to get a memory request through the levels of the hierarchy to DRAM and back. Probing each level of cache, propagating through the miss queues, translation (maybe with TLB miss), waiting for the DRAM controller, etc.
In India, life under coronavirus brings blue skies and clean air
Their reaction to the massive outbreak has been effective.

My point is that they reacted the second half of January, after trying to cover up the outbreak for weeks/months. If the local and regional officials had acted effectively in late December, there might not be a global pandemic.
People have been best for having been associated with outbreak regions in China India and the US. People have been attacked for looking different like Muslims in India or Black's/Whites in China, Asian in Europe/Americas.
Hmm can you explain that more... I know that will eventually turn into logistic curve or something like that. Please clarify me, as I said I am just bored curios human asking silly questions.
I seen this all the time. Our colloquial term for these is "my malware uses the driver." since most of them seem to make this claim.

"Why your antivirus did not detect malware?
Answer: My malware uses the driver, I update its signatures every 4 hours so that your antivirus is silent."

Terrible code and terrible situations can be encountered in any language.

I had a project that gave all sorts of hints of stink that was Java based. Turns out that project involved integrating a system in a preexisting code base with tens of millions of lines of code. Limited documentation, so much abstraction Java was just a syntax of underlying conformity, the language was understanding the myriad of interdependent abstractions to accomplish the integration task. Documentation was incredibly limited given the scale of everything. Obviously, progress was painfully slow.

Java itself was not the problem, everything else was.
Like I said, it has limitations.

But your comparison is also not really fair, since you assume everything runs and is stored on your local computer. This is not the case anymore at all.

Plus, the web browser is probably the first application that is started by a user.

Following applications all run in my browser:
- email
- video conferencing with screen sharing
- (persistent) chatting
- Office applications (word processor, spreadsheet, ...)
- photo storage
- games
- development sandboxes
- ...

In fact most Apps I have on my phone could just be PWA's.

I'm not saying we should all go web, but I'm saying that most things where you want to use electron, you could let it run on the web.
Remote work, regional lockdowns and migration of Internet usage
I like it. Kinda reminds me of jump[1] which at a period I was using a lot but forgot about it when I got a newer laptop and did the "oh crap, I miss that, I'll install it tomorrow" for 3 weeks and eventually forgot about it.

For those who do not know the show, it shares the same ambiance as Homeland, but it is far more realistic and disturbing.
True but their collab demo uses a separate network to infer depth information from a simple RGB picture (its a classical task nowadays) so it is not a problem in practice.
More precisely, the etymology of cybernetics refers to the steerer or helmsman of a ship (the kybernetes). The point is that in the middle of the sea, where there are no stable landmarks, the helmsman cannot navigate by means of pre-establish, static laws in the vein of a mathematician or philosopher. Instead, through interpreting the meaning of celestial bodies, winds, currents, birds, and so on, they have to continuously check their reasoning - they have to find balance. Navigation, medicine and military strategy all shared this mode of knowledge - cunning [metis] - for the ancient Greeks.

Norbert Wiener chose the term cybernetics on the one hand because he was well versed in the classics (he would communicate with his father in Latin, and he wanted to name his popular accompaniment to Cybernetics 'Pandora' but his editor refused and called it the Human Use of Human Beings), and he knew this ancient etymology.

He also chose it because the Latinate translation of kybernetes is 'governor', and that's what James Watt called the self regulating device he installed in his seminal steam engine. The fact that calling his project Cybernetics also rooted it in the tradition of James Clarke Maxwell's famous paper 'On Governors' was not lost on Wiener.

There's no firm evidence as to why Watt himself called the device a 'governor', however he would have known that in 17C England there was a cottage industry of windmill hackers, effectively, who'd introduced mechanisms to regulate the force of windmill sails upon their grinding stones, and they called these mechanisms 'governors'.

In British English a 'governor' is still a term for someone who supervises you.
The point of ReactOS is not really to run legacy apps - Wine on Linux is enough for that. It's to run legacy proprietary drivers, for hardware that will never be properly supported on Linux absent a tedious reverse-engineering effort. (Similar to running LineageOS on a phone instead of a far more compelling PostmarketOS.)
When I've seen the thread, it had like 500 comments. My comment wouldn't make a blimp and like five people would have seen it, so I just didn't post it.
I'm assuming the programming languages that CMSs people are using are written in, hence the dominance of PHP and Node.js.
Other than constraints most of the issues you raise are just as likely to happen in modern languages as well. That comes down to how the team was managed. If anything I have found a lot of older code over documented. My difficulty when I had assist in migrating some old COBOL from CICS on a zSeries was understanding their file structure techniques. However that was easily remedied by understanding the task as hand so that the data was better represented on the new system.

Is it a trap? Well if you want a secure position in managing a code base and maybe eventually working with others to move it to a new platform I do not see how. I have been around enough new languages to know we are always going to run into code bases we just want nothing to do with but here we are.

The problem to me is you may land in a development shop that is not well maintained. The code has worked for so long that management outside the department just went assumed that everyone knew everything.

Interesting - if that's the case I would imagine it make sense for some systems to feature an architecture which skips the idea of multilevel cache entirely and has only RAM connected over a photonic bus. No probing, no cache misses.

Ask HN: You are not angry at Facebook, You are angry at your friends
With so many people stuck in their homes in quarantine, people have turned back to social media to seek social interaction.

Did you also notice people post these "games" & "experiments" that seek human connection with "friends"?

I saw a few about "reply with your initials of your name", "reply how you remember us instead of likes"

Why do people think they have to make it into a game, or call it an experiment to ask for messages from their friends?

I think this shows something about how our interaction with our friends have changed. We became reserved, resigned when it comes to online socializing. Nobody seems to be writing anyone these days. Before the quarantine, I thought it was just me, missing the sociable friendly days of online presence with our friends. Now I see everyone is seeking that thing when the physical world is fully under quarantine.

If everyone has been in this situation, what does that say about the society?

Are we all just pretending to be angry at Facebook? While in fact we have been angry at each other, resigned from social interaction online?
They're encouraging people to identify and report them so they can be eradicated.
Both question can have trivially true answers (a textbook one for magnets, cucumbers for the green kilogram), both are nonsense if you dig deeper.
So men have perhaps twice the rate of infection and death than women. One thing I can't understand is why there has been no government advice about this. I would have thought it would be sensible advice that if a man and a women are in isolation together, the woman should go shopping rather than the man, especially as usually the man is older in a marriage. I would have thought that this simple change could save many many lives, so I wonder why no government has suggested it?
Why do you think a position as an NGO executive selects for that? Executives in general, yes. NGOs too?
The UK government has proved it can't be trusted with that technology, neither can google. I'm disappointed that apple have bought into this panic.

And yes, in the UK the local busybodies are complaining about people walking down the road in fancy dress, and families out together for a walk
That doesn’t seem particularly plausible. Covid doesn’t exactly appear subtle

What I think he meant is more like "either do things the functional Haskell way or you don't do them", as in, there is no non-functional fallback or alternative in the language, which some functional languages have.
Ask HN: Do you think org-mode would be a killer app for the WYSIWYG TeXmacs?

Just gave 35 of these NIH-approved ones to an ER doctor yesterday who was quite happy to receive them: [1]

Note that to make them actually comfortable you'll need button hole elastic as well as foam padding (I used 1/2 inch by 1/4 inch foam window seal). This design is superior to the Prusa and Apple ones because it adds additional protection at the top to keep particles from floating down onto your face. It takes longer to print, though, so the Prusa people don't like it as much.

A few other notes:

The face shield shortage is disappearing pretty quickly in the US. From conversations with a few healthcare workers, it sounds like there won't be much of a shortage for these by the end of the month. What they really need are surgical-grade N95 masks and certified ventilators.

Please don't try to make DIY ventilators. See [2] for an explanation of why a lot of these well-meaning projects do more harm than good.

Another thing that's easy to make are surgical mask strap extenders to go behind your head so your ears aren't constantly strained by the elastic. Example in [3]. I gave these to a few healthcare workers who requested them. Personally, I don't think they actually work that well on the mask I have without using hair pins to hold them in place (they should really have a rubberized coating to keep them from sliding down your head), but they're still better than nothing.

> There's a difference between a microservices architecture and putting in services where they make sense. We build mostly monoliths at work but we still split things into services where necessary.

It seems that your problem has more to do with semantics than with what microservices are.

Arguably, the definition of a microservices architecture is "not a monolith", in the sense that it's a distributed system not only with regard to support and infrastructure services but also with regards to business logic.
I was the team lead to rewrite a large APL codebase with a very small team as part of a much larger group that refused to change and I'll agree with this. Once we started documenting and building tests for the code that replaced APL it became clear that the complicated bits were easy to replace and the hard part was just man hours converting all the conditional logic.
I really recommend to check GIST [1] as a replacement for pure roadmaps. It focuses on goals and some kind of experiments to define what should be implemented sooner.

GIST is as close to scientific approach as we have right now.

RICE model might help as well [2]

However, being 100% honest, I tried all the models above and they did not stick to me. I'm playing Product Manager role for 16 years already and rely on customers feedback + intuition. When you have deep experience in the domain, you internalize many models and your neural network in the brain quite often just makes the right decisions. Don't decide quickly though, rely on your "slow" subsystem, decide as late as possible (and collect evidence).

Another trivial observation is that customers almost always ask you about some kind of solution. They rarely provide real problems. PM job is to dig into problems as deep as possible and then find a solution. In many cases solution is completely different from what customers asked. In some cases problem can be solved without new features.

First sighting of mysterious Majorana fermion on a common metal
I imagined it was more in the sense of the 'Have fun implementing Quicksort!' variety, where you're fighting the language constructs, basically, to do what you want.
I personally don't use this approach because I feel like it leads you to a grab bag of features and not a cohesive product. A lot of product management in my experience is laying conceptual groundwork that no client or stakeholder directly asks for. That said, the following article expands on the "Monopoly money" approach, but applied to stakeholders:

Yes, this is where OP lost me.

> Published keys are 16 bytes, one for each day. If moderate numbers of smartphone users are infected in any given week, that's 100s of MBs for all phones to DL.

"Moderate" rate of infections is not millions of new cases per week worldwide. That would be such a catastrophe that contact tracing would be useless.
> On the other hand, you have the more general (philosophical, "woolly") part that's filled with comparisons to biology

But see, that "other" part is also really a generalized/philosophical/speculative etc. take on control theory. "Systems theory" in the cybernetics-related sense is basically a name for 'this control theory stuff is so cool/impressive, let's see if we can generalize it beyond its standard engineering domain and draw any uselful conclusions from it.' Of course this kind of interdisciplinarity would be seen as standard nowadays, you wouldn't need to call attention to it by trying to name a new field.
To (ab)use a completely overused quote "If I had asked people what they wanted, they would have said faster horses" -- Henry Ford

You should most certainly listen to your customers, after all, if you're not serving them, what's the point in the product? However, you shouldn't be reacting to their requests to the detriment of the product either.

Do you AB test new feature ideas? Do you gather data to suggest that the requested feature is actually going to make a positive impact? Do you measure impact after releasing a feature to see if it was the right call? If not, how the heck can you ever actually know if you're building something better?

You don't need to ignore your customers, but you also don't need to change priorities so often. Make a roadmap for X months and stick to it (we use 3 months, but something else might work better for you). Use the time that the roadmap is being worked on by the tech team to do discovery and research so that you know what the most valuable requests from your customers are. Collect metrics, create prototypes (design/ux prototypes, not technical prototypes) and test them with your customers, do customer interviews. Then when you're ready to, you'll have better prioritisation, and your teams will have had the space and stability to release the previous features (and hopefully had tech investment time as well to keep your systems maintainable).
