23:05 onwards in the first video

I hold a Class B ISP license. We get letters (not emails, physical letters)from Department of Telecommunication asking us to block http://www.example.com

We don't bother with blocking http://example.com or its https cousin.

In this case we have not received any letter for VLC

Absolutely, a more interesting tidbit is this -

Telecom companies cannot take small subscribers to court in India. You don't pay your bills, they can send legal notices, but not much beyond that. We have ~1B+ subscribers. Even if a small percentage goes into dispute, our judicial system will completely collapse.

Unrelated - I use kagi too! I was watching a supervised learning series on YouTube by Killian Weinberger here [0] and he used an email from kagi as an example of spam.

Self taught alert! I haven't gotten into fermentation of food waste yet, which would be very effective. But I make my own liquid fertilizer from food waste by passing it through the digestive system of maggots. Although this isn't very "bio available" because of more "complex" biomolecules, I have been getting fantastic results so far with greens, beans, cabbages, etc.

I followed the following [0] video for making a simple liquid fertilizer setup using 2 paint buckets (not in English but easy to follow). The advantage IMO is that risks associated with things like overfertilisation are minimised.

I'm in my 40s and I started a machine learning degree in Nov 2020, so it's been about 1.5 years for me till now. I am a slow learner and my recommendations may reflect the same.

1) Maths (precalculus and calculus) - I started with Khan Academy 10th grade onwards. I finished till grade 12 in a week. By this time I had gone through content elsewhere, so 1 week may (not) be enough. Regardless, Khan Academy app comes highly recommended.

I did realise that there were a few gaps (more basic in nature), I covered those with Eddie Woo on YouTube (e.g. why is zero factorial 1). For others I just looked up relevant searches online.

2) Maths (calculus) - MITs videos on YouTube. That is the pace of content I really love. Lots of overlap with Khan academy calculus, but do go through both. Also 3blue1brown "essence of calculus" playlist.

3) Maths (Basic Linear Algebra) - although if someone were to say Gilbert Strang's MIT videos, they would be bang on perfect, I had to start slower. Bingewatch (with popcorn and beer) 3blue1browns "Essence of linear algebra" on YouTube. Then move ahead to the channel "Math the beautiful" which has a slower pace. You would also wish to visit their website www.lem.ma where they have exercises. Then of course come back and start Prof Strang's lectures (you're delving into heavier stuff midway through his course).

4) Statistics - hands down professor Leonard on YouTube, he is the statistics equivalent of Eddie Woo. Slow, smart, funny and he has biceps too ;-) After this Prof Tsitsikilis (MIT) on YouTube.

It goes without saying that you'll need to practice problems (ironical, coming from me). You can download question sets of your country from online.

5) When you've done the above, your search for "linear algebra" and "calculus" on HN will yield a lot of lovely results. Hidden gems will be there in comments too. Check those books, interactive books, websites, etc out. Your pace will be good by this time, but you will occassionally come across something which you have not come across before.

If there's anything else, feel free to ask.

I first used it to dual boot windows (98 or NT4 I don't remember) and slackware.

I can't remember specifics, but I dd ed the first 512B to a file and pointed the windows OS loader to that file. The specifics I don't remember are why I wanted to use the windows loader instead of LILO.

I should have phrased this as a question, instead of being dismissively declarative.

>If, upon hearing that "ripgrep can replace grep," you actually hear, "ripgrep can be used in every instance grep can be used, in exactly the same way, for the same use cases, with exactly the same bug-for-bug behavior," then no, ripgrep trivially cannot replace grep. Moreover, ripgrep will never replace grep. If, upon hearing that "ripgrep can replace grep," you actually hear, "ripgrep can replace grep in some cases and not in other use cases," then yes, that is indeed true!

I think this statement says it all.

I don't like find. Nor do I like vi (not vim, vi) and/or maybe others. I don't wish to stamp on someone's parade who's more accomplished than I am. But I think these "new" tools miss the point.

I use vi because I know it exists on every(?) system ever. It's not like I go out of my way seeking vi. I feel the feeling is similar for find. It works. It works well. It works the same on all systems I work on.

Would I go out of my way to install find on my system? Probably not.

I always thought we couldn't have our own mail clients with services like ctemplar and protonmail. Will have to recheck.

>Or are you using some sort of a 2.4GHz dongle that just shows up as an audio interface?

Yeah, stupid me never ever thought of that;-)

>So I tend to stick to minimalist solutions such as dwm.

I tried my hand at tiling WMs with pop!OS, I just couldn't wrap my hand around it (pun intended). I really admire people who work through all the keyboard shortcuts. It's just not for my capabilities.

I went all in ~1 month ago after using on servers since late 2000s. My findings:

1) can't have something like a /var mounted on iscsi. The Rd kernel doesn't support it. 2) help for DEs is patchy. In my example XFCE behaves differently on major linux distributions than mine. Intellij too is slightly different. 3) there are some bugs in upstream software which as an OpenBSD user are simply unacceptable to me. I had to disable compositing. 4) things like Bluetooth for some people (not me) may be a deal breaker. Bluetooth sound works perfectly. 5) if you want to use myfavsoftware X, you may have it in ports. But the reason you want to use it relies on mynotfavsoftware Y which may not be available on OpenBSD. 6) if you use OpenBSD you will become a cynic because of bad documentation most places elsewhere. I mean this seriously, I view rest of the world as moving on to just getting things done without giving thought to underlying correctness. Maybe it's a good thing, maybe not.

That said: 1) it is the easiest thing to operate. Like really easy. You know which file is doing what, when. 2) there are no gotchas. This is a very predictable and consistent system. 3) if it's not there in documentation, you don't have to ask "how to x", be rest assured if it's not there in the docs, it is not available, else it'd have been there. 4) contrary to public opinion, very very helpful community.

I think I am a fanboy. Previously have used (rev chronological order) - pop!os, enso OS, windows 10, snow leopard (another brilliant one), freebsd for a month, Ubuntu, redhat 5, XP, 2000, NT 4, 3.11. By far OpenBSD is something I have loved the most.

As someone who is approaching mid 40s and has gone back to college, I would say I disagree with you.

Ed tech is a problem yes, because you get only 1 kind of content on a single platform. But in general, computers have given me access to so much more than a singular human interaction could.

I'll use an example (real one). "Linear Algebra" search right here on HN yields a few results and I especially liked the animated web book. Gilbert Strang's videos are well... Gilbert Strang's videos. 3blue1brown throws a fantastic perspective. Pavel Grinfeld is brilliant too.

I have so many options now, which didn't exist in 1995. And each of them is so different and great in its own way.

Please correct me if I'm wrong. Aren't binaries in /sbin and /usr/sbin statically linked as opposed to no requirement like this for files living in /bin and /usr/bin?

I always thought the rationale was that if statically linked binaries are on different partition they can be used to recover the system from a failure.

Edit: files in /bin are also statically linked, and I am unsure about what I wrote above but vaguely recall something like that

2006 or 2007 (I forget which exact year) Mac-mini-server guy checking in. Sorry, just felt like bragging about an old computer. It had spinning disks, replaced with 2 SSDs.

Gifted to my dad 5+ years ago, he refuses to replace.

Anecdote: He thought it would be a great idea to clean up certain ports when I gave the mini to him, sprayed WD40 liberally. Then it was all wet and I suggested he put it under (2 ft away) a 60W bulb overnight. He's, well, my dad... So he placed a 100W bulb right next to it and forgot about it for an evening. The backpanel was black plastic and it melted into the mainboard. This thing refused to die, and will probably outlive all of us. Anything Apple post 2012 is yet another story at least for me.

Edit: still running, windows 10, 2 monitors

Unix history is always fascinating.

>None of this explains dd.

This one really made me think. I have never thought about dd before. Although I have wondered about other commands. Perhaps the author should also have added some command options not requiring a minus prefix, e.g. tar, ps.

The manpage [0] reads:

In the first (legacy) form, all option flags except for -C and -I must be contained within the first argument to tar and must not be prefixed by a hyphen (`-'). Option arguments, if any, are processed as subsequent arguments to tar and are processed in the order in which their corresponding option flags have been presented on the command line. In the second and preferred form, option flags may be given in any order and are immediately followed by their corresponding option argument values.

On OpenBSD, some of the scripts or utils (mandoc) are written in Perl because the developers prefer it. There have been some email chains on the mailing lists about having Perl in base. Most of them are interesting to read.

Thanks to your comment, I learnt about ignoredups as well

I deployed my own design (not calculated, eyeballed) of a buoyancy based passive cooling at my parents home near Mumbai, India. It did make a measured difference of approximately (temperature meters aren't very accurate) 2 degrees Celsius. I have been reading a lot in my spare time and your blog looks like a nice read.

My point is, is 2 to 3 degrees Celsius enough? From what I read is that I need to really move very large columns of air to make a sizeable impact. TBF my energy bills did come down by ~10%

>Over the years I've learned to a limited extent how to convey ideas without drawing on terminology which most people aren't familiar with, but that has taken decades of practice.

I think this is one of the most remarkable lifeskills to have. Personally, I feel stupid when I find myself between a jargon laced conversation. On the other hand, I respond very well to clearly communicated (not ELI5, but simple) ideas.

Putting things across as simply as possible is very difficult to master IMO.

Pardon my ignorance, I'm slightly technically challenged. But isn't this something similar to ceph cluster or maybe HAMMER2 with an explorer/fileman utility wrapped around it?

I mistook clove oil for olive oil too

>In my opinion, every supervised machine learning model is hopelessly biased by the intent of its creator(s). Namely, it inherits the bias of its training dataset (both geographic and semantic).

Profound. And True. Sometimes I wonder whether we can truly call them learning models at all.

I might be totally wrong, but was it "press F8 for flaps" before landing? MS flight simulator on 8 floppies was brilliant.

No sources, but there were comments here on HN in the past year which pointed out non industrial grade (for the lack of a better word) computers on board a Tesla.

My opinion is that with mechanical components it is easier to make a distinction in quality. With computers, we tend to stick to GHz or how many nanometers some tinfoil is.

I believe this [1] is the interview from which the quote is taken.

Thank you. One learns something new everyday. And I feel humbled by most comments I read here.

I did look up OpenBSD pf again, and it too does port knocking in the kernel. My information was dated (left the misc mailing list at least 5 years ago).

The folks at OpenBSD Misc do not recommend port knocking. IIRC one of the reasons stated was a possibility of getting locked out of your own server. I tried looking up the relevant thread, but am on the phone.

There was kagi.com here on HN a few weeks ago, I've been mighty pleased

I usually avoid posting here as I see far more intelligent people on this forum. Since you asked for conjecture...

I'd recommend Caspian Report's video [1] first. Secondly, if we look at Cuban missile crisis, US had a strong reaction to missiles around them. I see the Russian reaction pretty similar. They do not want NATO expansion and they do not want missiles in Poland.
