udev··on Ask HN: What problem are you close to solving and how can we help?
What kind of loads are we talking about here? How many requests per seconds? Or is each request response large?

Have you noticed whether it is worse for lots of small requests vs large data transfers?

I use a very similar setup, but haven't seen tinc CPU usage matter yet, though for very low traffic.

udev··on Impact of Pocket Listings on Housing
Genuine question: why would a rational seller accept to sell before listing the house on the market (MLS) to a widest possible audience?
udev··on Mastering Web Scraping in Python: Crawling from Scratch
Can you please elaborate?

Are you thinking more about the performance, or code maintainability?

One thing that is difficult is updating the BeautifulSoup code every time a website changes design/layout/etc.

udev··on American parents are sending their kids to 'Russian math' (2017)
A book that appeared previously on Hackernews is Lev Tarasov's "The world is built on probability". This is not striclty a textbook, but it is translated in English in a way that preserves a lot of the feel of the original: https://archive.org/details/TheWorldIsBuiltOnProbability

For examples of beautifully crafted exercises see this: https://www.imaginary.org/sites/default/files/taskbook_arnol...

There are plenty of books in Western literature where exercises are also very good, and not only in math, but other fields too. One that comes to mind is Jon Bentley's "Programming Pearls", which has very well chosen exercises.

udev··on American parents are sending their kids to 'Russian math' (2017)
Lots of comments asking what is "Soviet/Russian Math" actually like, and how is it different.

I was lucky to get an education in three systems (Soviet Math, Romanian Math School (influenced by both French and Soviet Math school), and finally in a world top 40 university in North America.

I would summarize the Soviet/Russian Math/Physics approach like this:

  - understanding of the mechanism/intuition behind the equations/methods is paramount
  - teachers are astute at spotting students who memorize blindly, and will intervene to correct that
  - while rigorous about notation, the mathematical representation always comes after understanding, not before
  - the progression of teaching (order how material is introduced) is very well thought out
  - the old soviet textbooks are generally less verbose than North American ones (less fancy), but high quality in their expression, typesetting, and ESPECIALLY (!!!) the quality of the exercises
  - the Soviet Math textbook exercises are something to behold: they have funny/memorable setting (like jokes), they are short and easy to express, the numbers are chosen in such a way that the result will be a nice whole number, or pi, etc. Basically as a kid you can read one of those problems, lay down, close your eyes, and work on it in your head.
That being said, I did like some of the aspects from the so called "Western Math" (in my case Canadian university):

  - teachers are more approachable, more friendly
  - textbooks can be gorgeous (nice colorful plots, etc)

udev··on Tesla CEO berated employees, investors and tried to get rid of safety measures
I've been observing one thing about Musk...

He seems to not have a surgically precise thinking at all times like some smart people do, but he is always right in the stochastic sense if you will, over longer periods of time, he tends to be exactly right.

(And I agree that he can be despicable at times. To me the "pedo" thing is unforgivable.)

udev··on Pelosi and a lifetime of trading
Isn't this just saying that Pelosi has a good financial advisor?
udev··on Mr. Rafieh’s Tehran Pencil Shop
A mightily photogenic place, so much colour!
udev··on Tact Filters (1996)
I tactlessly order you to elaborate.
udev··on Tact Filters (1996)
There is a much stronger argument for tactless communication.

In tactless mode there is little space for manipulation, misrepresentation, and other kinds of bullshit.

In tactless mode coercion cannot be sugarcoated, becomes overt, imposing a much higher social cost on the one attempting it.

All in all, tactless communication is much more efficient and clear, this is why it is used, e.g., in the military.

udev··on There are at least 10 different Microsoft design conventions in Windows 11
Downvotes from people who can't accept that one can dominate a market with many inconsistencies in your UI?

I guess the same people who applaud each time when Federighi anounces the redesign of the macOS trashcan icon.

udev··on There are at least 10 different Microsoft design conventions in Windows 11
Yes, and you need about 12 digits to write the net worth of Bill Gates, which is to say this does not matter as much as you think.
udev··on New Book by Stephen Wolfram: Combinators
Stephen Wolfram continues to shy away from the understating, unexagerrating language that is the norm in the best technical, scientific literature.

His writing is dominated by the I pronoun, and he keeps creating these complex sentences just to make sure it is clear that it was him who thought about that, and he concluded it, and it is his contribution, only he saw the connection, etc.

IMO this is distracting from the ideas themselves, for what they're worth.

udev··on Fungi on Mars? Evidence of Growth and Behavior from Sequential Images [pdf]
First author definitely creative with his titles.

This kind of papers are testament to the amount of data that we are bringing from Mars: multiple rovers with progressively better and better resolution cameras, and the orbiters.

As the amount of data coming from Mars will increase over the years we will see more such "creative" attempts to pick convenient subsets of this data and try to reach for conclusion.

But over time, I think, the wind will blow away the chaff and reveal real results, just like the marsian wind moves the sand around hiding and revealing pebbles at its surface.

udev··on Montana to cancel unemployment benefits to address severe workforce shortage
This is a sub-optimal solution.

If you want real results, just make being unemployed illegal.

No need to increase salaries... so is perfect!

Did not expect to see RedFlagDeals on Hacker News!

RFD is an amazing (Canadian) forum officially focused on shopping deals, but it is much more than that.

Just like HN, and maybe even more so, RFD has a user base very diverse in its expertise. People help each other make the best choice when making purchases.

As an example of this forum's impact on Canadian economy, consider this mega-thread started in 2006 (15 years ago) and still going strong (3668 pages) where a group mortgage brokers help people get significantly better deals compared to major banks (we are talking savings of $10-15k per 5 years): https://forums.redflagdeals.com/official-mortgage-rates-thre...

There are similar threads about renovating your house, buying a heat-pump, buying an electric car, buying a PS5 without scalpers, etc.

udev··on Show HN: I made a simulator for personal finance
What is a good offline alternative?

I hear Excel, but one needs also to know how an what to compute. Any books/guides in that sense?

udev··on Webamp: Winamp 2 in the browser
That equalizer curve for the Rock preset is burnt into my memory, its shape, and color, and positions of sliders.

Say what you want about the skeuomorphic design, but it really felt great to slide the volume a bit higher when at your favorite part of the song. It really felt like a piece of hardware in your hands.

udev··on Soviet TV version of Lord of the Rings rediscovered after 30 years
Context is essential for understanding art.

This was released in 1991, a period of great economic and political turmoil in Russia. They were essentially in the process of switching from one-party communism to a democratic system with real private property. Many organizations were undergoing rapid (often overnight) privatization.

Just to give you an idea of the economic chaos, inflation in 1992 was 2000%. You can imagine how that plays out for a production budget.

Yet, despite the turbulence, people tried to create and to entertain.

udev··on 20-Minute Neighborhoods
"the novelty of walking to a convenient store" <- this sounds funny

Not sure if sarcasm or figure of style of some sorts. If neither I recommend traveling to European/Asian/UK/Commonwealth cities where walking, convenience and safety are all combined seamlessly for large parts, if not whole, cities.

udev··on 20-Minute Neighborhoods
I love Montreal, but it seems you are describing the Plateau/Mile-End rather than Montreal as a whole.

But I agree, from the North American cities I visited, Montreal has the nicest, livable higher-density housing areas.

udev··on 20-Minute Neighborhoods
This is one of those things that the soviet cities did well.

They called this microraion (microdistrict): https://en.wikipedia.org/wiki/Microdistrict

An interesting side-effect is that house/appartment-hunting become much easier and less stressful because no matter which district you will choose there will be services (groceries, pharmacies, clinics, child-care, schools, parks, etc) withing walkable/very-short-ride distance, which allows population distribute and grow more-or-less evenly, without segregationist tendencies like in the West: "I need to buy there because of the school", or "I need to buy in that area to avoid the immigrants/ethnic/black/brown people from the other area", etc.

udev··on Don't End the Week with Nothing (2014)
I like the general thrust of this text, but not all of the individual pieces of advice, e.g. the go sexy, go work for a FANG company advice.

Aren't FANG companies fairly aggressive in their employment contracts with regards to side projects?

What are the chances that a Google employee can work on something on his own time that lawyers won't be able to see as reasonably related to one of the lines of business or research of Google?

udev··on Slonik: A PostgreSQL client with strict types, detailed logging, and assertions
As a memory aid, Slonik means "little elephant" in Russian, and probably other Slavic languages.
