I was under the impression that per reg T, you can borrow 100% of the equity value of your stock. So if you own $10,000 worth of stock, you can borrow $10,000 against it (but you will get margin called if there's a decline, so don't do that).

You're right however, if you want to acquire more shares using margin, then your equity needs to be at least 50% of the stock value, i.e. with $10k you can purchase (up to) $20k worth of stock.

Entirely depends on age and context. When I was a teen the group of friends I ran with would be constantly attempting to "hack" the other, so you were always on guard. Honestly I attribute that more than most things to my early interest in computer security and getting my foot in the door with programming. It turned into a pretty nice career so far. Sure it got tiring sometimes, but overall it was a great life experience I wouldn't trade for anything.

We also kept this between ourselves. It's a much different situation if I "pwn" my friend who is attempting to do the same back to me vs. a typical normal kid.

Those practices learned put myself and my friends in a pretty unique mental space for the time. It was an age in time where all this stuff was new, computers truly did not do as much important life stuff, and being a teenager playing pranks and cat and mouse was fun. Just this stupid "real world" experience in your mid/late teens was enough to typically get an entry level job in IT - typically starting off with more skills than your superiors.

What was NOT OK were the few guys who never grew out of that BS. I ended a business partnership after I found out my "partner" had opened my workstation and removed the BIOS battery to reset things, and install a keylogger. At that point it's no longer funny, it was not a novel or interesting attack, and was simply being an untrustworthy asshole.

I think it's common in communist leaning circles in general. I've talked with a few of the fine folks of anti-fa on twitter, who express similar views. I think it makes sense in the context of the worldview. After all, why let one man's words lead to the mental detriment of thousands?

Distributions exist because people have their own opinions on the best way to do things. Pick one you like and learn it.

If your complaint is that this isn't all obvious then I wholeheartedly agree with you. But this is genuinely a simple case of you not RTFM.

I did Common Lisp back in college for several years, it's a great language. But good luck getting a job with it. Clojure on the other hand, I've been paying my bills with that for the last few years. The main difference is a much larger community, and therefore lots more libraries for real-world stuff, and sitting on the JVM you have a lot of options integrating with existing corporate stuff.
Very interested to see how he/they propose to expedite the boring process.
There are many things to love in Clojure, like core.async, the lispyness, etc. But for me, their biggest breakthrough is with no doubt the data-structures.

Clojure default of immutable hash maps and vectors was really bold. They had to innovate by giving a twist to Bagwell's great research on data-structures, and they managed to build what in my opinion are the first set of general data-structures suitable of representing traditional hierarchical object-tree data-models immutably, at the scale of large interactive software.

Without these, the single-atom architecture that now is popular as ever with Redux, Elm, etc. would not be possible. The flourishing of functional programming for interactive software that followed shows to me that the biggest impediment before was not the lack of functional ways of expressing interactions (the Haskell people have devoted a lot of notable effort in the FRP camp). Instead, just having efficient data-structures to write persistent document models, escaping the rigidity of lists and rb-trees, allows you to write big interactive sofware in a functional manner even with the most dumb abstractions (which is a good thing, KISS!) and even stupid language (JavaScript!).

This has inspired me to work on a generic implementation in C++, which also has experimental Python and Guile bindings:
https://sinusoid.es/immer/
https://github.com/arximboldi/immer/

In the past I also did some other work on bringing Clojure Transducers to C++ (https://www.youtube.com/watch?v=vohGJjGxtJQ&t=1614s) but I know consider it a much less important effort---without the data-structures the other parts of Clojure feel almost like just sugar.

It isn't off the bat if the rates are very different. Which seems to be the case: 50% doesn't seem to be in the highest bracket in Canada, according to the OP.
What Root's ('programmable bank') been up to
No, office AC is commercial. The energy reporting used here is to group it into residential, commercial, industrial, and transportation. Residential is houses and apartments. Commercial is stores, office buildings, theaters, etc. Industrial is factories, refineries, ports, mines, oil rigs, etc. Transportation is well, transportation. The article breaks down Texas's usage as: industrial >50%, transportation ~25%, residential 13%, commercial ~10%.

Which makes it odd that most of the discussion here is about climate and residential and commercial AC, neither of which are particularly significant factors. What's using most of Texas's energy are the chemical plants and refineries.
Can't say our machines are trained based on facts, but purely data. What you get out of it is from what you feed into it.

The challenge we are going to face in this AI era is that the training data can be biased or include some morally/politically incorrect information. Someone can intentionally manipulate the data and make us feel that the response from the machine is trustworthy and factual, which can be devastating if it is used by a dictating government. Mind the alternative facts!!!
This viewpoint is effectively British and Canadian law.

Who is searching for system package manager installed binaries in the filesystem by absolute path?

On Arch pacman -Ql <package> shows me the equivalent of a /Program/<package>/ directory.

Installed packages are organized for the benefit of the runtime environment since the user should never have to interact with the data hierarchy, much like how Android has a Data/<program name>/<random stufF> share dir with the packages cached elsewhere.

The only real problem I have with the current standard FHS is how terribly named everything is. There are mechanical reasons why having all your libraries in /lib or all your binaries in /bin is necessary to the environment and linker.
No way.
AWS is prohibitively expensive at scale as are decent managed servers.
Several jobs back. Startup with 150k to spend on IT.

* Buy 75k hardware.
* Two colos <= 30k yearly + full managed support.
* One PT SA 45K.

That AWS budget doesn't touch scaling like the ability to
scale across two sites and physical hardware for multiple years.
You have to match development with domain experts. Development has to take time away from domain experts until you can pay them and not everyone is willing to be a free part of a development lifecycle.

Finding anything more than vague ideas requires connections and the other person not knowing the value of being able to describe their problem (otherwise, why wouldn't they just learn programming and build something themselves?).

Was going to reply something something about sandboxing but then I realized: If we're going to sandbox native apps, I'd rather it be done by a cross-platform standard like wasm instead of done differently by each vendor.

The fact is, this web assembly stuff could be seen in some ways as a response to the walled gardens being built by each vendor right now. I prefer native apps too, but if we're going to have walled gardens, why not one big one we can share.

> This situation also poses a big problem for the development of new operating systems.

I am currently developing a new kind of operating system using nothing but web technologies (ie, it is technically a single-page web app). It might not be the same kind of legacy hardware-centric operating system that most techies fret over, as I am just interested in "userland" ideas (ie, what new kinds of applications can we build, using what new kinds of higher-order abstractions). IMO, the kinds of research programs you are thinking of are really, practically speaking, solved problems.

Also, my OS is compatible with POSIX, as it is the first (that I know of) Javascript implementation of IEEE Std. 1003.1 (Shell Command Language).

The project is called "Linux on the Web" :

- https://linuxontheweb.org

~or~

- https://linuxontheweb.appspot.com

As individual developers, we really need to start thinking of web browsers as the hardware layer, virtualized as it may be. Just as the scripting languages of the early 90's allowed us all to start thinking at higher levels at the language layer, modern web browsers allow us to start thinking at higher levels at the OS layer.
Because in your home country, wages are lower, which makes everything cheaper than in Canada (I'm taking a guess here, since you mention some Eastern European country).

Also, I'm very much pro-environment and everything, but the reality is that regulations have a real cost. e.g. fire safety, parking space etc. Not to mention taxes for local, state and federal level... it adds up to make shit expensive.
If you ignore scale, sure. A handyman pocketing $100 in cash here and there is a good deal different from a company whose whims could affect the trajectory of the economy.
I was fortunate enough to be given the opportunity to learn Clojure on the job. A majority of my work is on the web side (JavaScript, et al.), so learning Clojure was a fun and interesting challenge.

After the initial hurdle of getting used to a Lisp I found the language very liberating. I definitely approach problems very differently than I did prior to learning Clojure, even when flipping back to JavaScript land. I find my approach is vastly different that it was before. The best way to describe my way of thinking is that I'm very "data first" now.
Wait, 30 min a day is addiction?
I work in Scala and it has live code update, interactive worksheets and a repl.

As for type systems increasing complexity I think that depends on the application. As a beginner to Clojure I would pass unstructured data around all over the place and then have the mental overhead of trying to remember the structure or fix it all at runtime.

I can occasionally get away with writing Clojure for "real" work, but for hobbying (and inshallah for real work someday) my goto is Racket. I feel like Racket is something of an optimum among the lisps in terms of brain expanding, modernity, tooling, libraries, docs, and community.
Except neither of those cases involve making software to be sold for purposes of common theft and fraud.
I agree. I read through Clojure for the Brave and True, and played with it a bit, but it was too much new stuff at once coming from an only Python background.

I'm reading Structure and Interpretation of Computer Programs right now and everything is clicking. I'm looking forward to going back to Clojure after I get through more of SICP.

> What news sources would we be reading if we were physicists, or medical doctors, and wouldn't those be interesting even if we don't have these professions?

It is incredibly fascinating to delve into other professions' rich data sources. It's also sometimes hard to do. I'm very fortunate in my current job that I am surrounded by PhDs in the hard sciences, and I've been richly rewarded by looking at what they are reading at work, not least of which because being a simple software engineer, I need to have at least a basic fluency in their domains to be effective at implementing their ideas in code.

Much as I'm not a fan of print media or transient data, there is value in a piece of advice I heard years ago: every month, go somewhere with a wide variety of magazines and pick one at random, preferably something you know nothing about or have never heard of before, and read it (libraries are underrated for this). Online is nice and convenient, but we tend to get locked into echo chambers and have search algorithms (and just natural human linking habits) create bubbles that don't force us to think about new and different things.
Sure, I've been pranked (old shaving cream on the hand while sleeping comes to mind) and I'm sure I've participated in pranks but none come to mind right now.

HOWEVER, there's a huge difference between a harmless prank and betraying someone's trust to be mean to them. I consider keylogging and pwning someone's machine deep into the in the "asshole" category. I also think that jerking someone's mouse when they are trying to click is not clever, just annoying, not funny. Especially because it could more effectively be done physically. It's in the same league as tripping someone when they walk by - just dick behavior.

A prank is something the pranked can laugh at, not just the pranker.

Since I was just leaning to explore my sexuality during that time and my IM messages and emails reflected that I'd be pretty horrified to know someone stole my password, pwned my machine, and read them. Like, seriously horrified and very violated.
You do know that there are thousands of companies in the warehouse automation space, right? And that "pad and paper" (whatever broad brush that is supposed to mean) isn't really used anymore for anything but small warehouses that wouldn't be a profitable target for warehouse automation software? And that there aren't any "market leaders" that own most of the warehouses...you'd have to lock up thousands of the biggest companies even before you got to 10% market share?

I understand the point you're trying to make, but that was a terrible example. Even then, I don't agree with the answer. Complexity isn't a deterrent to market, otherwise some company would have locked up international import/export by now. The market's response to complexity isn't typically a monopoly but rather very fragmented hyperspecialization (which is the case for both international import/export and warehouse automation).

What people are suggesting here is very well studied in economics: it's called a natural monopoly. And suggesting that you just focus on building a natural monopoly is about as facile as suggesting you just become a billionaire. Building a natural monopoly takes a mountain of time, money, and expertise. It's way harder to build a natural monopoly than it is to build a $1B business that has to compete.
The flip side of this is if you're only spending $10-20 on a vps setup you're probably going to be nicely covered by the free tier on AWS. Either for at least a year or possibly for the eternity of your account.

It's worse than you might think. There are at least three things happening 2000x/second: getting an interrupt, writing shared memory, and returning. Getting a CPU interrupt takes something like 1k cycles. Dealing with the APIC may be even worse on a system without X2APIC, which is all too common due to crappy firmware (never benchmarked it, though), and returning takes many hundreds of cycles because x86 is very bad at these things. That shared memory write is n basically free unless NUMA is involved, and then it can be fairly bad.

So we're taking maybe 4M cycles per second used here. In practice, there's probably quite a bit of extra software overhead.
Have you ever had to work with a piece of software, where, since you were not using Gentoo or something, your package manager had a very old package and had to install a new version from source?

I remember around 1999 some sysadmins would say, create your own packages from source stuff that you need. Given the current filesystem, permissions, etc. creating your own stuff is not for the faint of heart. So what you did was search the web in hopes somebody had done it for you.

Fast forward to recent times, if you had to do devops where PHP was involved in some way, you would have felt remi was a guy that should be receiving free beer. Explain why we have arrived to that sort of situations.

Luckily nowadays, the world seems to have centered around Ubuntu, from Docker to whatnot, which makes everybody target Ubuntu at least. But to this day, I'm still a very fond user of Gentoo, even if the compile everything from source approach is a bit crazy, and its latest reincarnation, Funtoo, precisely because it gives me a machine that has everything I need when the time comes to deal with "the package not in my package manager" TM.

There's also something to be said for still being online when the rest of the internet is dark because of an AWS outage - for being able to take action when something goes wrong.

I am a classic arrogant developer (I'll learn it all at once as I go) but in retrospect it was honestly a mistake.

I am not sure if I should keep my focus on Elixir, or switch back to go - I love both languages, they are awesome.
