Yes they do. But you need a sufficiently powerful one to be able to circulate the air in the room enough times per hour, more that the circulation that occurs through the doors, windows and even walls.

Eco-rated houses have a circulation of about 2-3 times per hour. Older houses that are well insulated are about 5-6 times per hour. The purifier needs to be powerfull enough to spin the entire air volume couple of times faster than the natural circulation.

If your windows and doors leak too much, or if you open them too much, or if you burn oil / light up cigars too much and produce smoke then it might be pointless.

I live in one of the cities where the pollution is regularly at the top 10 in the world, and the unit I have is able to reduce the pollution inside to a level that is 5-6 times lower than outside if it runs constantly in a mode that is like 30% of the power. It could do better, but it would be too loud for me.
A lightweight online utility to host them as JSON so I can edit them from anywhere and then export to Netscape Bookmark format. The specification of the format is probably the silliest one on the entire web [1]. Then importing manually the HTML to all browsers on all machines, sigh. Looking around for some self-hosted solution or established but necessarily lightweight online solution.

I’m building a tracing JIT for CRuby based on some ideas from LuaJIT, including trace stitching.

One major issue is the optimization scope is limited by how root traces are formed. This is fine in Lua but a much bigger issue for Ruby.
That sounds positive. In contrast, a similar situation at Berkeley had a disastrous outcome -- all Berkeley's historical non-captioned videos of lectures were taken down.

I kind of agree, but if you take the premise of Sapiens that homo sapiens is distinct from other animals in ability to organize around stories rather than more immediate drivers of behaviour - then this may just be part of the human condition.
Hey I built https://www.linkdrop.co/ about 6 months ago to solve exactly that problem.

Linkdrop doesn't have any unread article lists. When you "save" an article, it queues it up to send it to you in an email the next day.

Since I've been using it I find that my actual bookmarks are things I want to save instead of just random articles. Makes things a lot cleaner :)

It's got a good number of users atm and things are running smoothly, it's also free. If you do use it, feel free to send me any feedback you have. I've been trying to find more time to hack on it and would love some more direction.
On the other side of this, I had a relative slowly waste away from cancer. There were no lingering questions, possessions were given away, goodbyes were said, and when the day came, everyone in the family had made peace with it, with the exception of her partner who had to endure the daily emotional burden of her suffering and care. I didn't cry at the funeral: it was as if she had died while still alive. For my relative though, the process was extremely expensive, painful, and undignified: in the end she basically starved to death in anguish, and frankly I think all of the family would have preferred her not to go out in this way.
Another leaky abstraction.
I took the liberty of editing a sentence near the end of the article.

> Steven Udvar-Hazy, executive chairman of aircraft leasing company Air Lease, which has 150 of these cursed planes on order, said, according to Reuters, that his company “asked Boeing to get rid of that word MAX. I think that word MAX should go down in the history books as a bad name for an aircraft.”

Should read:

> ... Air Lease ... “asked Boeing to get rid of ... MAX. I think that ... MAX should go down in the history books as a bad ... aircraft.”
I think it depends on the lateness as well though. Sometimes the baby dies in the womb and this is discovered before birth, yet the mother still has to go through a full labour, all the while knowing it's for nothing. Pretty horrible.
If it's not clear (the article does say "if not[,] you will need to get a license from the creator"), it's because most memes and GIFs take a copyrighted image/clip before adding a caption to it.

E.g. in the article there is an image from the copyrighted work "Dawson's Creek".

Very sad to read that. Yet, by the way, why do they always use lethal doses of morphine for euthanasia? I.e. I would strongly prefer a lethal dose of 5-MeO-DMT (which feels like spiritual ascension and dissolution in pure light, union with the universe and non-duality, and then you just forget to breathe in case of a lethal dose) for myself.
These are still very few compared to every other desktop available out there. I said they are rare, not that they do not exist.

If statscounter isn't up to your liking, then check:

https://www.screenresolution.org/ (typical desktop HiDPI resolutions like 3840x2160 are at ~0.1%)

https://store.steampowered.com/hwsurvey/Steam-Hardware-Softw... (gamers tend to have higher specs in their computers and 4K is a big trend in places like /r/buildapc and /r/pcgaming yet 4K is at just 1.51%)

https://www.statista.com/statistics/487487/leading-desktop-s... (only for UK and a couple years old but the likelihood of the statistics going dramatically up is very low)

Look, if all you work with is Macbooks and similar computers, it is very likely that your view is biased (pretty much like the people who wonder why others are making a fuss about Electron applications when they can run several of them without issues). According to this (1 year old):

https://www.cultofmac.com/618730/q1-2019-pc-market-apple-mac...

...Apple only had around 7% of the global market share of computer sales between big brands and not only that is very low but also it doesn't include local brands that assemble the computers themselves nor custom built computers (even though i do not believe this is a big number, considering the size of the custom built market that exists, it still is a significant number). And it is about all Mac sales, including the lower end iMac (that have a regular DPI monitor) and monitorless desktops like Mac Mini that can be connected to a regular DPI monitor.

HiDPI on desktop might be a mainstream thing in 10 years or so, but right now every single statistic available shows otherwise. On mobile is a different story though (which is why i tried to avoid any statistics page that focuses on mobile).
I have the same problem and have started using https://raindrop.io

Hope it serves you well
seconded... I love my pinboard. It's nice to have bookmarks, it's much nicer to be able to find them later.
Well...I'm working on my own thing (FOSS)

https://github.com/calpaterson/quarchive

It's quite early but I'm able to use it as a near replacement for pinboard (including search but not including tags). I have circa 6k bookmarks so I feel your pain.

It's based on sync of your browser bookmarks via an extension. This works well because it allows you to bookmark on your phone.

Here are some features I have planned:

1. Show what pages link to a bookmark

2. Show discussions (HN/Reddit/Lobsters) about a bookmark

3. Full text search (including of PDFs), perhaps including the above discussions

4. The ability to additionally just record everything you browse (including full text)

Right now it works for me but looks a bit basic - I plan to soup up the graphic design once I have the MVP working:

https://i.imgur.com/5VdgGU7.png

I'm hoping to make it available as a hosted service at some point

If you're interested in this topic, have feature ideas or are even interested in working on it with me either comment here or please send me email - cal@calpaterson.com . I know social bookmarking is not trendy any more but I still use it a lot and pinboard is a bit limited.
He did tell me directly that he regretted it later on. Though it didn't keep him up at night.

I think the current tech industry rat race and churn is socially stifling in the sense that you must become nomadic and chase opportunity. By the time you settle in its time to move again. I see people working the same job at the same company with families and homes who although make less than the average tech worker, appear to me much more happy and fulfilled in life.
I don't see why income can't be treated as income no matter where it comes from.
Oh no, oh no no no... Please tell me you are joking. The good news though is that World War III is officially cancelled now. If anyone will ever decide to start it, they would probably debug crashing pods and spaghetti code in startup scripts for years afterwards.
Honestly I'd say you accusing the parent of a red herring is pretty much a red herring, given that the parent is very aware that the people in question are deaf.

Your resource argument doesn't hold up either, especially with money. Things can become cheap if society values them enough to invest time to make them cheap. Most of that time is currently being invested in making middle- and upper-class people's lives more comfortable (eg most unicorns out of SF) but that doesn't mean it _has_ to be that way.

Drugs could be cheaper (or not become absurdly expensive), places could be accessible, people wouldn't have to be homeless... It's clearly a resource allocation problem, but you make it sound like resources are very well allocated right now. I don't think they are.
I think one thing that's overlooked in Cancer research is how much ground has been, and will continue to be broken in terms of basic biological research to solve the problems required.

To even define and understand the problem properly we have to solve a bunch of things. Then to get to a solution a bunch of other things need to be figured out and can be integrated into humanities knowledge base. On top of that things can be dragged in from other fields to get a sense of how biology responds at various scales: genetic, tissue, organ, system, whole person. It's a perplexing and fascinating disease to grapple with.

> Julia base syntax is closer to how people write math

As someone who is a Julia fan, but has a background from mathematics rather than computer science, I don't agree. Julia syntax resembles mathematics only on a very superficial typographic level that have little actual significance when reading or writing code.

Mathematical notation, unlike code, is fundamentally two-dimensional, with vertically written fractions, subscripts and superscripts, etc. Simple mathematical expressions are easy to read in both Julia and S-expression notation. More complicated expressions are hard to read in Julia (I sometimes have to write them out by hand on paper in order to understand them), while the same expressions written in properly indented S-expression syntax with a generous use of newlines are easy to read. They are somehow structurally more similar to standard 2-dimensional mathematical notation, despite the superficial infix vs prefix differences.

What attracted me in the first place to Common Lisp (my first programming language) as a person with no technical skills or experience was the friendly and intuitive syntax. It was the first programming language I saw that didn't look visually intimidating. These days I use Julia, but I use it for the awesome features, libraries and community, not for the syntax. I would love Julia even more if it used S-expressions.
Can you link to this phage paper please. I'm about to start a project looking at phages.
Yeah, I'm not arguing that we are simply like other animals, but rather that we aren't organizing our work efforts in a way more cognizant of our nature. Instead, most productivity advice seems to be about fooling or 'hacking' yourself into being some sort of machine.

Enjoy it while the cost of fuel doesn’t include the environmental costs. Future generations will end up paying for the comforts of these years. That is not to say NYC is ideal, but moving mass over great distances is not free.

Obviously, simply living isn’t free either, and who’s to say what this generation is entitled to consume versus the future ones.
I threw everything in a checkvist (https://checkvist.com) list and generously annotated every bookmark with tags, now I have bookmarks and attached notes and it's searchable with tags, it works really good !

I think this offers the exact same thing as the popular pinboard but it's free !
Does the US have any sort of capital gains allowance? In the UK you can make £12000 (about $16000) of capital gains every year tax free so this covers most smaller investors, etc.
The Metamorphosis of Prime Intellect [1] describes a post-singularity world where an AI prevents people from dying permanently, and one woman in protest takes up finding creative ways to kill herself (and getting stopped and patched up each time) and turns it into a sport with a following...

Another vote for Pinboard. I have over 12,000 bookmarks. It's simple, fast, and flexible. You do need a system for choosing tags or things can get lost easily.
Better yet, use Revise.jl and do

This will cause file.jl to get automatically reloaded whenever it is changed.
Pollution sensors for indoor use that can be plug via USB to the mobile phone are really cheap, you can find laser ones like Nova SDS for $17 and some that are not so precise come even cheaper than that.

So unless the author buys a real PM2.5 sensor and does a test in a true room and not a box of the size of a Desktop PC, with the sensor on the opposite side of the room, and proves that the pollution drops to below 8micrograms/m3, in a reasonable time frame, than we can say that it is working.

Until than we can only say that the purifier is only able to purify a desktop PC.
The tax system in the US is commonly used to encourage behaviors the state finds desirable and discourage others. Capital gains are taxed lower because of the perception that that money will get reinvested and that investments are good for the economy.
This provision already applies to transactions in foreign currency; that is, if I take a trip to Japan and exchange $1000 for yen, I don’t have to report gains every time I buy something as the exchange rate has fluctuated since the time I made the initial conversion.

This bill would include digital currency under that rule, so buying a cup of coffee with Bitcoin would no longer trigger recognition of capital gains income.

I think the headline should be modified to make it clear that 95% of purchases of goods and services using digital currency would be exempt from gains, but that most crypto transactions are for trading and investing purposes anyway so gains would still be recognized.

Air pollution: health risk could depend on your class, ethnicity or gender
I'm not a doctor but for some reason I get anxious about this as well. You said you run? My logic is that if I had a heart defect it would have showed itself playing sports growing up or during my time in the service.

That was a good essay.

I just want to add the point about proofs. Different type systems in programming languages are partial proofs about some aspects of the program. There exists continuum in type systems were it proves more and more about the program without completely validating it.

If you do safety critical programs, the type system is never good enough. That's why the choice of programming language is not that important. C used in combination with static analyzer based on abstract interpretation and formal verification does more through analysis and can often prove that there are no run time errors.

Ideally you would like to have a language with tooling where you can use TLA+, SAT, SMT, abstract interpretation, dependent types to prove different aspects and get full verification that way.
Oh my brain skipped that!
maybe I'm "that guy", but why does everything have to have thumbnails and icons these days? that's so much space that's wasted instead of harboring more information... we need more geeky, dense, info-rich UIs
While Youtube auto captioning has a superior performance compared to Google Translate output. In youtube translations there is much more language specific nuance. In many European languages a more formal word for the English word "you" exists, in German it is "Sie", French "Vous".

Correct interpretations of these nuances are applied by Youtube, Google however translates "you" by default to the most formal option.

So to me $1 dollar per minute sounds like an awesome deal because there is not much to adjust.

Out of curiosity, can you link to such a gig company?
TBH, even human transcribers have their limits. I often get transcripts of my podcasts. But if I have someone with a strong accent, I’ll often skip because I know I’ll be charged for a difficult transcription especially around technical terms and I’ll still have to do a lot of cleanup.

Surely the ADA requirement isn’t for a near perfect transcript.

That actually makes me wonder re podcasts and other audio. Is there any reason they’d have a different requirement or are these lawsuits specifically about video for some reason?
This hypothesis is as widely accepted as it's unsupported by any evidence. It's also quite insidious as it underlies many "social justice" efforts to police language. Insidious, because while the benefits are very likely to be non-existent, the censorious consequences and the contentiousness they generate are very real.

According to the Citizen's Budget Commission >The Citizens Budget Commission (CBC) is a nonpartisan, nonprofit civic organization whose mission is to achieve constructive change in the finances and services of New York City and New York State government. Our mission is rooted in serving the citizenry at large, rather than narrow special interests; preserving public resources, whether financial or human; and focusing on the well-being of future New Yorkers, the most underrepresented group in city and state government.

See Figure 1 of their Report at https://cbcny.org/research/rent-and-ride for a comparison of housing plus transportation costs for a median income household for 20 cities. Miami is the lowest; San Jose is the highest. Figure 3 shows housing and transportation as a percentage of median income. Washington, DC is the lowest; Phoenix is the highest.

The study appears to be based on the city, not the metro area. Cities vary considerably in how much of the metro is covered by the city, what percent of city workers live outside, what percent reverse commute, etc.

In the extreme it is ridiculous, but in small doses it is actually not so unreasonable.

The government is not an effective force at stopping people doing things that most of everyone thinks should be done. Government prohibitions work best when there is a small & unpopular minority which is being bought into line.

Contrast an alcohol prohibition with laws prohibiting murder. One of those is popularly supported and generally effective. The other is a good example of the law creating a wrongdoing out of nothing.
More specifically, Herpes Simplex. I don't remember where I read it, but I recall a paper arguing for Herpes being one of the viruses considered for causing (some cases of) Alzheimer's.

I don't understand how you can even imply that it's because of a stupid reason like that.

No the reason is that there are fundamental differences in the risk profile of the civilian and military sector.

Adversaries will insert spies in mission critical projects if they are publicly accessible. Once the main contributors stop maintaining the project the military will have to hire people and train them for maintenance but all the people that can train the replacements have already left. The military has to verify every single line of code every time the code base is updated.

All of these problems don't exist in projects where the full life cycle is taken care of by the military.

The internet of things suffers from the same problems. Once you are dependent on a vendor and that vendor shuts down or cancels a product you're stuck with a lot of paperweights. The vendor is usually not acting in your interest.

I've been using Linux since the days of hand crafting Modeline entries for an unstable XFree86 running as root, and installed FreeBSD a number of times over the years but never really enjoyed the userspace as much as GNU. I simply preferred the ergonomics of GNU, it's what was more familiar since I was introduced to UNIX via GNU/Linux in my teens.

Having said that however, I absolutely loved the FreeBSD books by Marshall Kirk McKusick. The red hardcover Design and Implementation of FreeBSD book was my go-to bathroom reading for well over a year. I also was lucky enough to attend viewings of VHS recordings from his operating systems class featuring FreeBSD. Those tapes were something like $1k/tape if memory serves, a friend's employer bought the entire set and would host group viewings on weekends. Such great memories from those times, McKusick was humorous and never missed an opportunity to take jabs at emacs while explaining how paging and swap worked, poor little vi being paged out because someone started emacs, etc.

There's a lot to love about FreeBSD, I hope it continues to exist and can attract enough new talent to thrive in the future.
