uniformlyrandom··on The effect of nuclear explosions on commercially packaged beverages [pdf] [1956]
"Some flavor change was found in the beverages by taste panels, more in beer than in soft drinks."
uniformlyrandom··on U.S. State Department phones hacked with Israeli company spyware
You do know that memory-safe languages are developed using memory-unsafe languages, and eventually execute the binary code on the actual CPU?
uniformlyrandom··on 2021 Tesla Model Y review: Nearly great, critically flawed
So this is how you get views and clicks these days - make a couple of factually incorrect statements, refuse to do any research, put a FUD clickbait in the title, and bingo - you are a "popular" "journalist".
uniformlyrandom··on Everything you ever wanted to know about UDP sockets but were afraid to ask
Thanks for the quality content.

You are absolutely right, there is very little documentation on UDP (probably because it was a pariah protocol reserved for "weird" things like DNS and SIP).

Now that UDP is becoming the mainstream, any documentation is highly appreciated.

Any chance of an article explaining difference in UDP handling between Linux and Windows? I've seen some weird client UDP issues on Windows side some time ago, and (unsurprisingly) found zero documentation explaining these issues.

uniformlyrandom··on Ask HN: What metrics do you pay attention to?
I have come down to one metric in the end - sleep time (tracking with sleep++ on apple watch).

The rest of the metrics lost meaning to me - they fluctuate too much depending on the weather / schedule / other factors. They also do not affect me as much as sleep.

uniformlyrandom··on French health authority advises against Moderna Covid-19 vaccine for under 30s
You are right. Anti-vaxxers have some valid points - admittedly, introducing a foreign substance into human body always carries some risks.

The problem with risks and probability is that human brain does not process probability numbers well, so it is all or nothing.

Anti-vaxxers point of view: I do not understand what 0.0001 is, round it up to 0.5 - OMG vaccines kill.

Vaxxers point of view: I do not understand what 0.0001 is, let us round it down to 0. Vaccines are harmless.

Second point is way more rational, although of course also incorrect.

uniformlyrandom··on A Single Register Value
Just wanted to say huge Thank You to the guys at Cloudflare for the awesome content. You post some of the best articles on Linux kernel, network stack and eBPF. I immensely enjoy these. Keep up the good work!
uniformlyrandom··on Elizabeth Holmes Trial: Why Not Other Tech CEOs?
I do not think Holmes was competent enough to understand that tech would never work (this is still up for debate though, "never" is a very broad timeframe).

Instead, she did waht every CEO does - hired people whom she believed to be capable of making the tech work, gave an optimistic world view to the investors to make sure she has the time/money to get to production, and demanded the results from her employees.

If anything, she was too successful - she got too much money, and she got Walgreens to agree to a test run way too early. The rest is textbook Silicon Valley.

uniformlyrandom··on AWS Frankfurt incident
Lost one node in a small ElasicSearch cluster. The incident did not affect the cluster availability. The node was reintegrated into the cluster once it came back online.
uniformlyrandom··on AWS Frankfurt incident
Last update:

The environmental conditions within the affected Availability Zone have now returned to normal levels. We will provide further details on the root cause in a subsequent posts, but *can confirm that there was no fire* within the facility.

uniformlyrandom··on AWS Frankfurt incident
The hardware is heat-resistant, so probably around ~75C (167F).
uniformlyrandom··on FDA authorizes Pfizer vaccine for kids age 12 to 15
COVID has many other long-term side-effects besides death (fatigue, muscle and joint pain, respiratory problems, etc). These side-effects are present in younger people as well. For me, mere possibility of these side-effects outweigh the risks, which are negligible for MRNA vaccines.
uniformlyrandom··on Linux Myths Series: Linux Doesn't Need an Antivirus (2020)
That is not a crazy idea at all. I'd feel a lot safer if I could run some detection on my personal Downloads folder, and on my apt feeds.

The problem is, Linux antivirus does not really exist.

Granted, there is some software that will scan your files for known signatures - but those signatures are for Win/Mac malware, which solves a completely different problem.

uniformlyrandom··on 533M Facebook users' phone numbers and personal data have been leaked online
SSN is used as taxpayer ID, that is why it is needed.

Now, there is absolutely no reason it could not be OTP'd (or uniquely derived for each account).

uniformlyrandom··on Whistleblower: Ubiquiti Breach “Catastrophic”
Except if it is awscli creds, then of course there is no MFA.
uniformlyrandom··on All my servers have an 8 GB empty file on disk
I would not say this is an alternative, more like yet another tool in a shed:

  1. Tunefs
  2. spacer.8gb
  3. lvm
uniformlyrandom··on Telegram: Voice Chats 2.0:Channels, Millions of Listeners, Recorded Chats
> Slack being killed by Microsoft Teams

The rumors of Slack demise are greatly exaggerated. Mostly by Microsoft.

uniformlyrandom··on Teaching a Bayesian spam filter to play chess (2005)
That was fun to read, thank you. There are obvious limitation to the approach, as stated by the author, but it was an interesting experiment.
uniformlyrandom··on Internet disrupted in Russia amid opposition protests
Yes, but application layer "weapons" are very democratic. Everyone can have one.
uniformlyrandom··on Internet disrupted in Russia amid opposition protests
This is Hacker News, not Facebook.

Arguably, the internet ends at the network level (TCP). Everything above it is just the payload. Application layer disruptions are not internet disruptions.

uniformlyrandom··on Internet disrupted in Russia amid opposition protests
According to the link, it was restored around 11am PST (10pm MSK)
uniformlyrandom··on Internet disrupted in Russia amid opposition protests
That was very different kind of disruption though, wasn't it?
uniformlyrandom··on Dropbox to cut 11% of its global workforce
Google drive unofficial client works pretty well for me on Linux.
uniformlyrandom··on The West’s Infernos Are Melting Our Sense of How Fire Works
California would rather use inmates as an almost-free resource to fight fires. Works even better than volunteer force.

Only this time, the inmates were already released because of COVID-19.

uniformlyrandom··on Epic Denied Preliminary Injunction for Fortnite, but Apple Can't Block Unreal
Except revenue, which they still very much need.
uniformlyrandom··on eBay is port scanning visitors to their website
Google's internal sso (which I accidentally stumbled upon) collects other endpoint-specific parameters to compose the digital signature (like browser window size and monitor size).

This feels more effective and less intrusive. Not sure why ebay went this rather weird and creepy way instead.

uniformlyrandom··on Analysis of population density thresholds in the influenza pandemic of 1918
Population density by zip code: http://zipatlas.com/us/zip-code-comparison/population-densit...
uniformlyrandom··on Analysis of population density thresholds in the influenza pandemic of 1918
For reference, current population density in popular places:

- Population density threshold from the article: 175/sq mi

- Santa Clara county: 1,400/sq mi

- New York City: 27,016/sq mi

- San Francisco: 17,246/sq mi

https://en.wikipedia.org/wiki/List_of_United_States_cities_b...

I believe that suburban population density still can provide significant advantage in infection rates/population loss over urban areas with extreme population density, despite being 10x the threshold for the last pandemic.

I guess we'll get access to that data pretty soon.

uniformlyrandom··on A chemical reaction in ancient Roman concrete makes it stronger over time (2017)
1. Only in salt water

2. Only over time

3. And actually we still do not know.

Slightly disappointing.

uniformlyrandom··on GitHub was down
Yep, it is Dunning-Kruger effect.

If rolling back works for a simple system, why wouldn't it work for a complex one?

Because one cannot step into the same river twice. Heraclitus would probably make a good engineering manager.
