I was torn between making a game, or making something to aid my musical endeavors.

I liked the idea of making a game, but as an adult I don't get to play that much. When I do, I play older games that stoke my nostalgia (JRPGs).

I play in an active punk band, and am a self admitted pedal addict.

I decided to go with music, because that's what I spend most of my passion time doing. Currently working on a really cool music related side project and couldn't be happier.

Also, I think scope has a big part to play. A video game is a huge endeavor that could take 5+ years developing solo, and most of my audio programming ideas might take 2+ weeks.
Thanks. Specifically, from your citation:

"In addition, angiotensin converting enzyme 2, the receptor for SARS-CoV-2, is expressed on myocytes and vascular endothelial cells, so there is at least theoretical potential possibility of direct cardiac involvement by the virus"

The most sane hypothesis I've seen is that the virus will attack any cell with the ACE2 receptor, including the heart and kidneys:

"Angiotensin converting enzyme 2 (ACE2) is an enzyme attached to the outer surface (cell membranes) of cells in the lungs, arteries, heart, kidney, and intestines."

This would require the virus to enter the bloodstream from the lungs, which is possible after sufficient alveolar damage.

ref: https://en.wikipedia.org/wiki/Angiotensin-converting_enzyme_...

As an aside, although Wikipedia doesn't mention it, testicular cells also express ACE2, leading to some worry about downstream fertility effects:

This was a key feature of the book for me; reading it really helped me grok that compilers/interpreters are just programs. Very complicated programs, perhaps, but still many of the same concerns that apply to my day job writing applications. It's code all the way down, and that feels like a hugely useful insight to have. Plus I think I now have the language bug myself. :)

Well done, Bob, and congratulations! Can't wait to be able to buy a copy.
Sorry, I should have been more clear and concise. Why do they want to limit exports from certified companies?

I think hate for giant IDEs & their corresponding resource consumption will generally come from devs who don't need all the features, or who have the usage of the features forced on them by their org when they may not be needed or there are more lightweight alternatives outside the IDE.

It's kind of an even-more-resource-intensive Microsoft Excel - almost no one needs all the features, but they all need a different subset.
No, they didn't. https://mobile.twitter.com/DOEChancellor/status/124689704627...
> It's a heavy thing. Do something with it in a well known way, get gains. Get a heavier thing, or do more, or do longer, or do it differently, get more gains, rinse, repeat. Adjust program based on goals and current progress.

I had a friend who said almost exactly this about the olympics: "The olympics should be about moving really fast, lifting really heavy things, and throwing things really far." Can't disagree with that. Subjective sports really grinds my gears.
Hey, that's a great idea! I could write a Javascript device that puts a number in the corner of the viewer's slide, with some indication of whether they were on the same page as the presenter, and which they could click to jump to wherever the presenter is currently.

It could also turn the pages automatically, for people who want that.

Thanks.
Compare the cost of masks to the cost of the salary of the people using them. Under no circumstance is the cost of masks a major cashflow concern.

Nothing in the article says these are N95 masks, I don't believe you are correct. But also, what does that have to do with my comment?
The motivation appears to come from recent news articles about how Chinese tests don’t work, or their respirators are faulty.

It turned out it was because non-certified Chinese companies were exporting these products, so the government cracked down.
Swift allows the same thing. In fact, Swift switch statements are powerful as all git-go. You can do things like specify ranges and whatnot.

After years of suffering the same problem, I found (so far) a solution that more or less works for me.
Assigns days to projects. Max of 5 projects. The most important thing is: Don't work in the project unless it's the day. If there is a need, add it to the backlog of the project.

My curve of interest gets reduce over a day. After one week of not working, it is restore.

Curious if this works out to someone else.

I'd love to see some data on this too.

One proxy for the benefit of beamforming might be the the available modulation types and coding rates in the various wifi specs.

The wikipedia articles on 802.11g, .11n, and .11ac have tables showing the nominal data rate for different MCS indicies (modulation and coding scheme).

Notably, 11n adds a 5/6 coding rate to 64 QAM modulation (on top of 2/3 and 3/4 found in 11g). In addition to that, 11ac adds another two rates with 256 QAM (3/4 and 5/6).

Since higher modulation indicies are generally only useful at higher S/N ratios, you might argue some combination of the following:

1. These higher rates exist only to boost the advertised speed of 802.11 products, and are useless in real-world scenarios
2. These rates are intended to be used when sitting very close to an 802.11 AP
3. These rates are intended to be used with directional antennas
4. These rates are useful in the real world and made possible by the antenna gain provided by beamforming.

If you believe the last one, then the benefit is around 30% to 50% more throughput (the data rate MCS-9 is 1.48x MCS-6). That's not counting the benefit you get from having multiple spatial streams, so the benefit is available in a scenario where the AP has multiple antennas and the devices has only one.
Self social engineering: tell everybody about it so you're going to lose face if you drop it without a good reason. This doesn't mean you cannot drop a project every week or two, but you must accomplish at least something before doing it or discover it's a dead end. And if you succeed people will cheer you.

I have a Vita, and it killed me on the Gaming UX side. But aside from that here's why the Vita failed to me.

- I hated the touchpad on the back. I'm in that subset of people who thinks the original 'Texas' Xbox controller is a good size for my hands, so I know that's very subjective. But I could never get comfortable with it.

- Using it doesn't feel as smooth as my times with a (3)DS or even the original PSP.

- Speaking Sony killed a shitton of goodwill with their winddown of the PSP for me. Yeah that's a nitpick but I think others had it as well which impacted uptake of the Vita.

- Proprietary memory cards that are too expensive. At least with memory stick I had a couple of options. Yeah I get that the new formats were to help with the piracy issues, but then making your proprietary cards so expensive just makes me feel soured.

- Loading times on the Vita still remind me of playing on a console with a hard drive.

That being said Nintendo has a lot more experience both from a hardware and software perspective so they are very hard to out-compete. The biggest indicator of that to me is the dearth of titles that are easy to do a few minutes on with a Switch/etc versus the kinds of games I have on my Vita which typically are better for something like a long flight or car ride.
This speaks to me on an almost spiritual level, I need to get this book!

This should be Wikidata. Wikipedia does that, but this is more and more moved into Wikidata. This is a good thing, because Wikidata is much easier to query, and the official website of an entity is stored at a single place, that is then reused by all articles about that entity in all languages.

How many professional ballet dancers don't have at least some significant permanent damage to their feet, legs, and spine?

Looser forms of contemporary dance can certainly be done safely. But there's a good case to be made for classical en pointe ballet being inherently physically dangerous to the point of being abusive, in a way that few other artistic or athletic activities are - outside of sports that rely on overt brutality, like boxing or MMA.

Just because it's clothed in swirly skirts and made-up prettiness doesn't mean it doesn't have a barbaric edge to it.

I use rclone to do account backups to B2 on my Virtualmin based web server that only supports S3 natively. I run a backup, rclone it to B2, then remove the local copy. Has been working wonderfully for quite a while now.

One of the wonderful things about rclone is that it's the right tool for so many jobs. Much like grep, sed, awk, etc, it is as simple or as complicated as you want it to be.

How do you perform in your day job? Do you have the same indecision or are you productive? If your productive at work, then perhaps consider what you are looking to achieve in a side project.

For me, my side projects are for fun and intellectual exploration. I’ve been making art-piece wordclocks as gifts and sell a few occasionally. This is totally orthogonal to my day job. The orthogonally is what I really crave. It gives my mind a nice refresh.

That is correct, but again, the reality is that the whole supply chain comes from China and fake 3M masks also exist. Also, no one is telling the hospitals not to ask for samples and test the goods themselves. The problem is that the hospitals don't even understand what they're up against on the supply side, and they have an expectation that 'legit' masks will just show up.

I've been knee deep in this stuff for the last two weeks or so, the article in this post is accurate from what I've seen on the supply side. This is also another accurate article - https://www.forbes.com/sites/daviddisalvo/2020/03/30/i-spent...
One thing worth pointing out is the article points to the sheer number of supplies leaving the country due to hospitals being unable to pay quickly enough. All I can say is, the demand is real, the supply is constrained, and not all the 'random internet people' are scammers - a lot of them are people with very deep resources and relationships in China actually trying to do their part to bring PPE.

In the end, donations aren't going to solve this problem. Reliable supply chains are, and reliable supply chains require that some small profit be made to cover material costs, cost of risk, cost of storage, etc.

But one Airbnb host told BBC News they had received no clear instructions from the platform to say they were not allowed to take reservations.

Maybe the platform hasn't been in touch, but the government advice has been pretty clear and consistent about no non-essential journeys. Why on earth would they think a holiday retreat would be exempt from that?
1. The WHAT should be something very important to someone else.

2. The HOW should be something very important to you.

Many experts tell you that you should build something that you actually need yourself. That may be good advise for start-ups but not as good for side projects. Why? Because it's too damn easy to just give up as soon as you hit an obstacle (and you WILL hit obstacles).

But when someone else is depending on your work (and becomes a trusted collaborator), they provide you with that extra UMMPH you will undoubtedly need when the going gets tough. It's a lot harder to bail out when someone is right next to you and depending on you.

But by deciding on your own HOW you will build it, you maintain an outlet for your passion. Believe me, I know. For me the journey of building something is more fun than the anticlimactic using of the finished product.

Works all the way around. Give it a try.
Maybe they are not so much trying to convince end users about the project, but other companies who might be willing to incorporate this into their products and contribute back to the project.

For that kind of use case having an organization like Eclipse Foundation, Apache Foundation or Linux Foundation on the background adds credibility.

Panic is a normal response to many situations. Panic can also be an abnormal response to normal stuff. When people experience panic that interferes with their day to day life, and causes them distress they may have an anxiety disorder.

Anxiety disorders are distressing and debilitating, and they lead to years of life lost to disability. Some of them have high rates of death by suicide.

Luckily, they're also very treatable. Most people experience pretty good recovery from an evidence based talking therapy. Sometimes that needs to be combined with medication, and sometimes the talking therapy needs to be repeated in a year or so.

So, hopefully, when people say "this sounds like a panic disorder" what they're really saying is "I understand the distress you're in, and here's some things that may help".

Ask HN: How much distributed tracing costs:Using OSS like Jaeger or paid product
Wanted to get your inputs on 2 solutions for tracing needs:
1. Open Source solutions like Jaeger - Is there a blog or link which analyses the cost of storage of traces to any of the backend like Cassandra or Elastic? Do you use any compression techniques before storing to DB?

2.Paid products like Datadog - Most of the vendors charge on a per-host basis. What's the underlying logic for charging like that?

If I were to use a vendor for this, I would like to be charged according to the number of spans sent for storage like in logs, say $2 per million spans or $0.2 per GB. Only Datadog seems to charge on such basis and asks for $1.7 per million of spans apart from $31 per host which covers 1M spans only. Does DataDog give you control of which spans to visualise & store?

- Does any vendor give you control of spans to process or a clear pricing estimate for the tracing part?

What other things should I look when using Jaeger or buying Datadog? My primary need is to monitor and debug my applications.

I knew someone at Hacker News will make a comment like this. Hacker News is cynicism at its finest.

"I can't imagine any hospital or doctor careless enough to connect one of these to a patient, even in this current emergency."

This is utter BS. Imagine that you are in a situation where you are trying to ration lives by selecting who gets access to a ventilator. Won't you not use this device then too?

Please, for god's sake, appreciate and be thankful that we have such great companies in US trying to help our people out. For perspective, if you were in a developing country, like India etc., all you have is hope and no company will be stepping up (they just don't have the technical wherewithalls).
Because Google optimizes for "quality content" since at least the Penguin update. They're using NLP tools to assess the writing quality (similar to algorithms telling you at what school grade level your writing is).

This was good, because it cured all the copy&pastable 2000s era "tag cloud" sites which simply dumped tons of search keywords all over the place.

Ideally, it lead to a stronger emphasis on high-quality human-written content, but it turns out that this algorithm, again, is easily fooled by feeding it "SEO essays" that looks like prose, but is irrelevant text gibberish, but written coherently.

That lead content creators to expand data that would ideally be presented in tabular form on one page, to multi-page "SEO prose" that looks like it's written for humans, but is completely undigestible.

That, along with Google's auto-suggestion feature that finish your sentences after you type in some words, especially on mobile, lead to the impression that people actually like to search in full sentences.
Prove it :D
But one of the ideas of being a non-profit (atleast in my mind) is that they are driven by idea of service to the community. It seems like a lot of hospitals are structured as non-profits, but really with a profit motive (not community service) with the profits being funneled to individuals and stake-holders (in manners that take advantage of the law!).

Basically it's hard to reconcile the fact that hospitals are "non-profit" while also charging what seems excessively for everything.

I haven't looked through financial statements of one of these hospitals, but does anyone else have any experience with doing so and do they actually see that hospitals do need to charge those enormous amounts for everything to run effectively or to survive?
I immediately sold my DS to fund getting a PSP as it actually had decent games I wanted to play with much better graphics. Now that I have a job, I'd love to buy a Switch, but again...not very many games that are really appealing as I haven't been big into Pokemon and games in that arena since Red came out. I think Doom and Diablo III and Skyrim are good to see, but I'd need to see more in that arena.
Hard deadlines. 48 hour game jams are great. Take Friday off from work, make a game on the weekend. If you miss the deadline on Sunday, you failed the game jam.

For me there is usually a point about 24 hours in where it seems like a hopeless amount of work, that I’ll never finish. However, I push through, and keep working, ruthlessly prioritize, cut every feature I don’t absolutely need, and finish making the game.

The game itself is not a side project that I stuck with, but the experience helps. Having the experience of “pushing through” and finishing a project with a specific goal is the real takeaway. Next time I’m stuck on a personal project, I can remember pushing through the game jam project and getting it done.

And finally… I only finish something like 5% of my projects, maybe. Don’t try to finish a project just because you started it.
