The matrix.org server deployment handles around 100K concurrent users these days across ~4M rooms, with ~30Hz of messages in and ~3000Hz of messages out - and these days has average traffic send time under 100ms.

DEFCON should be trivial by comparison, and as others have said, the HOPE server (2500 users or so) was a resounding success - so much so that it’s been set up as permenant fixture now post conference.

Now, it’s true that the Synapse server implementation has to be tuned - for large userbases you need worker processors and to dial up the caches a bit. And needless to say you need postgres rather than sqlite.

Kinda depressing that nobody from DEFCON synced with the Matrix team (to my knowledge) on how best to do this, rather than just writing it off as slow and bloated.
The Google Recorder app on Pixel phones (and I'm pretty sure general Android release) does super accurate on-device transcription, for what it's worth.
This is a slippery slope towards overworking, where work blends into life. This isn't how things should be. Unless you're a PhD student like me :)
Exactly. It could also be used as a tool to screen for companies that will benefit from growth in certain markets. For example, searching for 'electric vehicle' will show several companies that have developed components which can be used in electric vehicles.
I also like hiding the dock and the menu bar on macos.

On linux I like using a 4k display at 100%. I don't really care about window chrome, icons, etc. I care about text and mainly use a text editor, terminal and browser. They all allow me to set the text size. This way I get the best of both worlds: unobtrusive window chrome and legible text. This works great on a 24" display.
Because often people rely on that work and it needs to be done

A quick, cheap, non-invasive test that is less accurate (in the direction of more false positives) would be far more effective than a more accurate but slow, expensive, and intrusive test.
There's enough operator deployed wifi around for that already in most countries, so they don't need it.
But it did change. There was a time when things like childhood immunizations were ubiquitous in the US. There was a time when STEM education was heavily funded.

Then the cold war started to wrap up. And the anti-vaxxers came on the scene. And now everything about vaccinations is political. So we've seen a drastic change again.

Consider the CDC's data on pertussis over the last century to see an illustration of the outcomes. Note that death rates are still down, these are reported infections:

5G doesnt seem like its enabling anything fundamentally new. The talk of any ”killer app” based on having more throughput or on these optimizations always feels like demand generation and slightly inauthentic.

Are there any technologies enabled by these techniques that are not possible today?
I feel that I work more, but I spend less time at work. I may work 30 minutes more a day, on average, but save 2 hours commuting, $130 in mass transit and a bunch in lunch money. As others said, I can also modify my hours a bit as needed. I also have vastly more and longer meetings, unlike the article.
"First ones" could mean "former", as in comparison with latter:

Haskell doesn't have any more language extensions than other languages of its age, the only difference is that they're explicitly called out.

When Python adds new string formatters or generators or async, they're just in the language. When Haskell does that they require you to explicitly turn the new feature on. It's just a different strategy of managing language change. Versus the classical approach you get a lot more eyes on your language additions and have a nice "beta" period where you can make improvements before there is wide adoption.

This is basically the same approach that Rust is taking but they've been better about removing the feature flag when the feature is stabilized.
Many things that are worth doing aren't worth doing well.

It sounds like your connecting a bunch of dots that aren’t there. People get banned from Twitter every day, on both sides of the aisle. A Wired article from October 2018 about people connected to the Occupy movement being banned [1]: Twitter has purged left-wing accounts with no explanation.

Yes, I've been trying out Session for the last couple of days. I love the "take a breath" at the start, and I'm intrigued by the analytics (but don't have enough history yet)

I think you're that I'm probably not your target user: I don't pomodoro everyday, mostly when I start stressing out, get anxious, or can't focus. Before using Session I was just setting a timer on my Apple Watch.

I'm in favor of paying (or donating in the case of FOSS) for software that I use, but I know and appreciate pricing can be tricky to figure out.
Blown media converter is better than other equipment in your setup getting murdered.
not sure what your are getting at with the null hypothesis.

Look at the results. Mandatory cloth masks were associated with 3 times as many ILIs (Influenza Like Illnesses). So it is not some tiny statistical variation. It is a huge effect size.

As for the second study, it concludes:"The observed mechanisms may lead to more severe symptoms in individuals with impaired capacity for myocardial compensation."

I am talking about how the all sources of information systematically downplay the negative effects and serious side effects of masks.

Masks do have side effects. The relentless propaganda tells you that is a "mere inconvenience".
That whole meme about people burning an entire months worth of data in 10 minutes really misses the point though. What matters is the quantity of data you're transferring, not the duration it takes. If you're just surfing the web like usual then you're never going to be transferring gigabytes of data. In fact most of the wait time is humans reading the content rather than you magically downloading 4 GB of Javascript because you have more bandwidth (the caveat here being video streaming which usually does scale the bitrate up or down the depending on the users bandwidth; but you're still likely to quickly chew through your data allowance even on 4G).

Google also offers that. My point is that choice is good.
It's not heresy, it's just a banality that has been stated countless times before.

Not washing your hands properly can be counterproductive. Not being socially distant enough can be counterproductive.

If you're not even arguing against masks, what is your point?

How to understand gorilla/WebSocket lib?
i want to understand gorilla/websocket library.
but i was wondering should i start with current code : https://github.com/gorilla/websocket

or frist code(initial code): https://github.com/gorilla/websocket/tree/273ecadfcae3306e1943ac6d4160ef02cac48247
because was more simple then current code.

What is the easy way to understand the source code?

you can take the question as general question not this library only.

> For instance, with beamforming, the tower sends a directional signal to your phone based on its location instead of broadcasting an omnidirectional signal. This uses less power and supports for more users.

I think the biggest advantage is the other way around: devices using less battery power for transmitting signals, so batteries would last longer.

(And I'm betting that if receiving would be less power-intensive for these devices if the incoming signal has more power, then the towers would use more power, not less.)

But you're right about the other advantage of beamforming: less interference.
> You can make money any time

But big SV money? I wouldn't be so sure. Ageism is rampant in tech. FAANGs love their coders young, in 20's-30's. Also the dollar saved earlier in life is worth exponentially more later thanks to compound interest

There's no better place to solve your financial problems than in SV in your 20's.
Last mile for fixed rural wireless broadband seems like the obvious one. Today, this is generally done with either LTE or various proprietary things (or if you’re particularly unlucky, satellite). 5G should allow for greater total bandwidth, reducing the impact of contention.

And on the other side, it should be helpful for very dense urban usage. Try using LTE in a large city’s central train station at a busy time and see how you get on.

But yeah, not revolutionary, but should make existing LTE applications less awful in some scenarios where they struggle.

Beamforming and generally avoiding omnidirectional signal is something that's been around since at least HSDPA, iirc? At least that's when I heard of it in telco...
That is not what the paper found, all you need is to read the abstract:

"Cloth masks also had significantly higher rates of ILI compared with the control arm"

As for the second paper here is the summarry:

"The increased breathing resistance is especially problematic for patients with chronic obstructive pulmonary diseases. Patients with diffusion disorders have reduced capacity to compensate due to the reduced tidal volume. Another example of a population at risk is patients with heart failure. The observed mechanisms may lead to more severe symptoms in individuals with impaired capacity for myocardial compensation."

All I am pointing out is that masks are likely to have serious side effects, all which are completely disregarded and downplayed.
Dhall is an example of a configuration language. Its programs must terminate. It aims for safety, claiming that it can support safe evaluation of untrusted code.

TBH, I have no experience with it. But, it sounds like if you need a configuration language with programmatic features, it would be more suited to the job than a general purpose programming language.
I differentiate between "Flow" and "Mindfulness". Mindfulness can help you to achieve Flow much easier but that's more a side-effect.

IMHO:

-> Mindfulness is "constant emotional self-awareness". It's a skill that enables you to being aware of your emotions and state of mind while experiencing your day to day life. This sounds ridiculous until you realize that most people aren't aware of how emotions influence their rational decision-making. We can easily see how others become temporary irrational for emotional reasons but somehow we also try to denial that the same happens to us on a regular basis. A mindful person is in a way constantly calling theirself out in their mind (e.g. "I'm currently overenthusiastic/angry/anxious/etc. because of ...")

-> I think of "Flow" as a state of mind. It can be achieved by doing something that creates a positive feedback loop with challenges and achievements. This series of challenges can be of physical/cognitive/etc. nature but needs to be always of the right difficulty level. Too hard tasks will make you feel overwhelmed while easy tasks create boredom. Both extremes will make you lose your focus and/or motivation and that's where mindfulness can be helpful. Once you become aware of the problem, you can adjust the difficulty level by adjusting the difficulty with better goal-setting and other productivity tricks. Hit the sweet spot multiple times in a row and you achieve Flow.
There are winners and losers here for sure. Long commutes are gone but many people relied on their commute keeping their work hours more strictly bounded. You’re right that the the office camaraderie is mostly gone—-assuming your office ever had any! I do miss lunchtime chats with coworkers—-and morning chit chat as we settle into the day. Unfortunately as more people shift their hours to better fit their different lives the possibility of a lunchtime connect goes away entirely.

But, this has given me an idea to try and start a lunchtime video chat at work. It might be harder with teammates in different timezones, and God forbid should it ever become mandatory. But it sounds nice in theory...
My favorite Dilbert of all time ;-)
We don’t have data caps in Finland and the ISPs have not lobbied for those, as most people simply do not use large amounts of data a month. We also have a relatively fast internet so if I wanted to, i could burn terabytes of data a month.

What is this based on?
Reading through this, it doesn't sound like the people involved considered the amount of outright misuse some of these features are likely to enable.

Haven't we already seen bad actors will misuse mobile tech to track our movements, spy on people, (etc) on a wholesale scale?

This seems to be wilfully charging down the road of making it worse?
In a Periscope anecdote, Scott Adams of Dilbert fame went on about 5G bringing enrichment via eyewear such that profiles of people you meet pop up, and any other VR variation you can imagine.

The geek can groove on turning cities into the holodeck on the Enterprise.

But one surmises that the appeal of gadget-free living in the country will grow, also.

Seems hard to derive a good balance point with "enough" technology for optimal enjoyment without begetting Big Brother along the way.

I'm technically working longer because I'm not spending 70-120 additional minutes of each day commuting 14 miles to/from the office. Despite working longer, I still end up having more free time.

It is amazing how I manage to rationalize sitting in traffic for that amount of time every day to myself.

Nothing in the law forces them to restrict resale of their products. If anything, it might be an antitrust violation. Some abusive patent suits might be antitrust violations as well. See e.g https://www.cnbc.com/2019/11/20/apple-intel-file-antitrust-c...
Support for most hardware depends on applying latest patches for HW and SW. Only if you explicitly bought as HPC or Lab environment with the appropriate contract specifying performance you might get around that.
I think the 27" is in a sweet spot. Big enough to be able to display several things (2 editor columns + docs + console for example) but not too big so that it's not visible all at once.

Now if it would be possible to get a 27" 5k screen like the new imacs, that would be absolutely great. Same "actual resolution" as the older 27" but with much sharper text.
Last years CCC has a lot of 5G related videos.
I doubt the results completely account for the airflow effect, and perhaps the researchers were careful enough to note this.

After all, they merely tested one infected person speaking at whatever level is normal for that person at that stage of the disease. It's quite possible that the typical carrier has stronger flow. Besides, sometimes people yell - quite a few people have reason to be on edge these days.

In this community economics would be decentralist and Henry-Georgian, politics Kropotkinesque and co-operative. Science and technology would be used as though, like the Sabbath, they had been made for man, not (as at present and still more so in the Brave New World) as though man were to be adapted and enslaved to them.

Being in occupied territory also meant that the Germans had a huge supply of slave labor from Belgians and Frenchmen, which they weren't shy about using.[1]

Even to the extent that the Entente occupied hostile territory (which was much rarer), they had a much greater respect for human rights. The British, French and Americans had strong liberal democratic traditions, whereas Germany was a highly autocratic and militaristic society verging on totalitarianism by the time the war started.

If you're in Switzerland like the OP, the Swiss government has comprehensive maps of fiber coverage [0] as well as the speed you can attain [1] (there are more breakdowns, check Geocatalog > Population and Economy > Communication.

Even better, you can download the maps and load them into GIS software. I grab listings from real-estate portals then load them into QGIS, where I intersect them with zoning maps, fiber coverage, noise maps and public transit isochrones. I can then filter them at will.

Road to Genius: Beginner No.10
The smartphone architecture is smart and well executed, but it is nothing revolutionary. The key is definitely that Intel has lost its manufacturing lead, which is letting other chip companies release competitive CPU architectures. Moore's law ending has leveled the playing field for ASICs.
Fair to whom?

It’s fair to the country as the country is able to make informed admission decisions weighted by the needs of the country, rather than a take-all-comers model.

It’s fair to the applicants as they have a clear set of guidelines as to what they need to do to become eligible for admission. Need to learn English to boost your score (As in Canada)? Cool. That’s tangible and clear. On the other hand America’s system of, roughly speaking, “Indians need not apply” isn’t exactly fair to the applicants.

Note: a points based migration scheme doesn’t preclude for instance refugee admissions, and Canada’s system has a points escape hatch if a province nominates you based on their specific needs too.
Related note: anyone with a qualifying engineering degree can [become a patent practitioner][1].

I stumbled across this while looking into law school and was surprised to see my Computer Science degree was all I needed to qualify for the exam. The exam is difficult from the sense that each question has a good amount of information you need to process and 100 questions is mentally straining. However, the exam is open book and you basically have everything you need to figure out all the questions during the exam.

The exam is also relatively cheap, somewhere around $500 total (not including any additional learning materials, I use [OmniPrep][2]), and allows you to practice as a patent practitioner nationally.

A similar phenomenon I have heard about is searching out old music records/albums. I think part of this is about completing some ancient want/need from one's childhood, or matching achievements of one's childhood role models. Resources and time are finite, so the thought of experiencing something you missed out on as a child that could potentially fill some hole or increase fulfillment is enticing. It often doesn't, but examining this behavior from the viewpoint of coming to terms with loss makes a lot of sense.
Hah, funny to see my blog referenced. Yeah, cache misses are a huge part of SAT solving (modern solvers have prefetch code specifically for this loop, some seemingly following the code I wrote). And SAT solving is about 95+% of SMT solving. So, yeah, cache is where it's at.

I once had an old, but "enthusiast" i7 that had a 3-lane mem setup, and "upgraded" to a consumer dual-lane i7 that was 2-3 gens ahead. It had the same performance(!) for SAT solving. Was pretty eye-opening.
