I found it very interesting, and it’s a very interesting application of cryptography (and, though far less appreciated) economics and game theory which really motivated the learning for me.

Start with Bitcoin, it has a good white paper, is the simplest, and is proven at scale. You’ll want to be careful chasing hype, even if you aren’t buying any. It can lead you down a dozen different highly complex proposals for the next big thing which haven’t been proven and often just monetize buzzwords.

Applications beyond is a bit of a misnomer. If the tech is built from blockchain as its backbone or exploits its benefits there is inherently an economic factor serving as a deterrent for tampering, so even if your application is not specifically money, it may take advantage of a system (blockchain) whose fundamental property relies on being scarce and transferable.

I wish more people who did invest in crypto took your approach, then invested after.

I interview at FAANG and we do take this into account by holding pretty much anyone over ~2 years of experience to the same standard with respect to leetcode questions.

A fresh grad is expect to be able to solve ~medium problems.

Someone with ~2 years of experience is expected to be able to solve ~hard problems.

Someone with 10 or 20 years of experience is still only expected to be able to solve ~hard problems.

The standards for a more experienced candidate are of course higher for other attributes: Leadership skills, communication skills, etc.
Good to hear you liked Render, and sorry for the confusion between Jobs and Cron Jobs (we have an open task to improve docs for both).

Heroku Scheduler = Cron Jobs on Render. Would you mind emailing me (see profile) or support@render.com with details on your Rake tasks so we can take a look?
Take a look at this list of academics, all working in or around crypto, producing research that materially solves real problems in computing, not just in blockchain or crypto.

https://iohk.io/en/team/#team=research

Then realise that eschewing it all because you don't like crypto is probably one of the most closed minded and regressive decisions you could make.
> Do you prefer if I explicitly add my affiliation in every comment that mentions bamboolib?

Personally I thought your original post's tone implied that you weren't affiliated to me personally.

You don't have to add a formal 'disclosure', but you could just say "I built x which is..." rather than "Another product is x which is...".
It is very barebones, I can't use it as a full-time IDE yet.
Being good at leetcode just requires grinding out those silly problems until you become good at them. That's the sad reality. Unfortunately, there's limited carry-over from years of experience of Actually Building Things(tm) so it can be frustrating. The upside is you're not having to learn language constructs or syntax like all the newbies are.

My advice is to just vote with your feet and not work for companies that leetcode interview.
In many cases you are absolutely right, the appointment times can be adjusted according to train schedule, destinations are nice places where you can find something to do in between etc. Public transportation in Germany in most cases is better than cars (I do not even have driving license for that reason - never needed it). Still, the calculation logic is right: when you travel somewhere to be there at certain time, you need to include some buffers in your planning, both for trains and for cars. Every 4th train in Germany arrives with delays and not every appointment can be planned for your convenience.
An MS Surface Pro 7 with an Intel Core i5-7300U is fanless. I know I won't be getting the very bleeding edge topmost performance with fanless, but I can still get it plenty awesome. The silence is just a different level of experience, that I'm absolutely addicted to.
Second follow up.

Results are not impressive until they are :)

It's certainly not a solved problem, and it's easy to have a pessimistic view now but I'm generally bullish on where things will be 10 years from now.
I didn't mean it in a "cultism" way at all. I was more saying that the point of leetcode isn't to discover if someone is a great engineer but to discover if they are capable of becoming one. Big tech figures if you're capable of becoming a great engineer you either already are due to experience or soon will be because they'll make you into one.

They've decided things like ability to devote time to a meaningless skill that is required to get the job, attention to detail, and problem solving skills are what is required to become a great engineer and see that letcode is a good way to test for those things at massive scale.
The problem is that actual work experience doesn't give you this. The more experience you gain shipping working software, especially in a senior capacity, the less exposure you're likely to have to the skills tested for in the algorithm-based whiteboard interview. We don't write algorithms often, but based on this style of interview, you'd assume that's what we do primarily, or even mostly. Some of my time is spent putting together the solution to a business user's request. The rest is spent reading other peoples' code to figure out where I can safely add the new feature, writing the feature (which rarely involves algorithms), writing automated tests for the feature, and babysitting my PR to production. Asking a candidate to solve a gnarly merge conflict is more relevant than asking them to produce an algorithm on a whiteboard.
Tell that to the Sun. We already have a fusion reactor sufficient to meet all of humanity's energy needs, it's a gravitationally contained fusion reactor with a projected lifetime of at least one billion years, so why not just rely on that? Seems to have done wonders for the biosphere for the last one billion years, hasn't it?
You still need to generate all the permutations, even if you use dynamic programming.
Mito is open source, but using Pro features does actually require a Pro or enterprise license. You can check out this callout in the license [1], as well as the restrictions on Mito Pro features here [2]. We're in the process of fixing up the upgrade to Pro process a bit... as you can tell... :)

You can of course fork Mito and turn off telemetry as long as you open source your changes! Go for it - happy to hop on a call and help you get set up with the codebase, if you want. Yay open source!

I'm trying to point out there is plastic consumption where you don't even know, or can't get rid of. In your starbucks example for example. Using a reusable mug and making your own coffee is obvious. What is not obvious is all the plastic and petrochemical derived products used in getting that coffee to your grocery store, or door. It's sent to your grocery, or you, in plastic bags, the mug was fired with natural gas, on and on. You can't avoid it unless you sail to the tropics in your own sailboat, pick the beans, process them into coffee, and sail back.

I'm not trying to pick on you, or your lifestyle, quite the opposite. I'm just trying to point out its not so simple as to say don't use plastics, or all plastics are evil, because they're inherent in our modern life. You couldn't read this comment without plastics. My other comments in this topic talk about reducing our consumption, making more responsible decisions on how we use our resources, all of that is in line with your goals. We just can't be so extreme to say get rid of all plastics, because we're simply all not willing to roll thr technology clock back 50 years across our entire society. It needs to be a gradual weening off, a gradual March toward responsibility.
I’m familiar with the others and use them as well.

My comment was answering a question about “why stablecoins at all”.

To answer your question, because some uniswap v3 pools with USDT offered competitive returns, like the 0.05% WETH/USDT one. That was one of many I used, which included those that paired DAI or USDC with ETH.

I considered the concerns overblown at the time and so was okay with making some the USDT pools a part of my LP portfolio.

I’m honest.

Very cool. Reminds me of the "Wochenende-ticket" DB sold in the 90s. It was something like 30DM and was good for travel on all regional DB trains for up to 5 people.

I used it with a group of friends to travel to Berlin from The Netherlands in 1993. I was a bit of a rail geek (still am, I guess) and had purchased a "Kursbuch" on a previous trip to Germany. This was a 2000 or so page, 3 pound book that contained all the timetables for all German trains. We pored over the timetables for hours to find an optimal route from the closest German border station to Berlin. I remember it being relatively few trains, something like Bad Bentheim - Osnabrueck - Bielefeld - Kassel - Dessau (!) - Berlin. It was a fun trip, lots of people were traveling long distance on local trains and Berlin attracted very...interesting people at that time.

After arriving in Berlin we sold our ticket, which was still good for another day, for 15DM.
> Where it all goes wrong in other cases is "Bob claim it's his and applies for a writ". i.e. it becomes Bob's responsibility to prove his ownership in court, rather than the government's job to prove anything at all.

I said at least twice that it's the government's job to prove that it's Alice's and not Bob's.

You proposed a hypothetical scenario where there is plenty of evidence to prove beyond a reasonable doubt that this cash was the result of a crime by Alice. So, when Bob comes and claims the cash is his, present that evidence. It's not a matter of Bob proving that it's his; it's a matter of Bob proving that this "beyond reasonable doubt" evidence you have of Alice's crime is bogus.

We're getting really into the weeds here; I'd expect a lot of the precedents to be established by a series of cases. But I would think that a reasonable starting point would be that possession implies ownership by default; and that if the government wants to prove that the money that was in Bob's possession is not Bob's, then the burden of proof is on the government to prove that. In your hypothetical scenario, there is plenty of evidence that the money is not in fact Bob's, so it's not an issue.

If it turns out the evidence that the money is really Alice's drug money is actually pretty thin, that's a reason Bob should get the money back.
For anything to work efficiently in crypto it always needs to be centralised e.g. OpenSea, Coinbase. Both of which hilariously are backed by a16z. As Scott G says... "meet the new boss... it's your old boss"

For a more future oriented version (as setting a font to black wont work with dark pages), check out the CSS Color Module Level 5 spec for color-contrast(), which will automatically choose a color that has a proper contrast ratio: https://www.w3.org/TR/css-color-5/#funcdef-color-contrast

One caveat is it's currently only supported in Safari technical preview.

Another thing worth mentioning is the relative brightness algo used in the repo for the linked plugin is using the WCAG 2 formula for relative luminance. This works pretty well in light mode for non-colored backgrounds, but doesn't incorporate perceived luminosity differences of different hues very well. A better algorithm to use here is the Advanced Perceptual Contrast Algorithm (APCA), which is the one used in the WCAG 3 working spec. It more accurately accounts for hue: https://github.com/Myndex/SAPC-APCA

How to Store an lvalue or an rvalue in the Same Object
Article is about the government, consisting of CDU and SPD at the time (2017), removing important parts of their report on poverty. Affected were passages about the growing low-wage sector, wage inequality and inequality of wealth overall, as well as reports on how poverty affects political influence and the growth of the economy.
It appears as if the government had a disregard about the social and democratic implecations of poverty. The previous government of CDU and FDP did something similar in 2012 and was criticized for it by the SPD

yeah, it takes more time in jira to create a task with a deadline and get it in a sprint and make sure it has an owner and find it in the backlog and move it through the workflow's steps than "is unused? delete". heck, sometimes the task takes less time than loading jira's website.

task systems are frequently awful at team-owned (not necessarily an individual) lightweight checks.
Working with encryption more broadly will equip you to understand the fundamentals that underpin the web3/crypto world: hashes, asymmetric crypto, signatures, signature chains, etc. And this knowledge also has many uses, of course, outside the web3 realm.

If you're working with Node, tweetnacl.js (https://github.com/dchest/tweetnacl-js) gives you secure defaults and a nice API to start learning and building with. Otherwise, look for a nacl/libsodium library in your language of choice.

Once you're familiar with this stuff, blockchains/cryptocurrency/web3 lose a lot of their mystery. They're essentially all just different takes on using key management and signature chains to verify identities and
maintain immutable action logs.
These appliances can also be caching load balancers or caching reverse proxies. Which can make very good use of ram.
> much worse than the infamous Digg redesign

Having used reddit on & off since ~2008, it's amusing to see them make virtually the same mistakes as Digg. I'm surprised that there hasn't been a similar exodus.
Did those numbers ever make sense? Assuming they did, then pinning them to inflation would have kept them sane without needing additional legislation.
Not only are there lanes to bypass traffic, almost more important is that the traffic lights are controlled to prioritize the busses. Thus if a bus comes the traffic lights turn and hold green so that the cars in front of the bus can clear the crossing for the bus.

And there are dense schedules, so that if one bus is delayed to some problem the next one is close by, thus gap is little.

Just a quick reminder, we already have practical fusion with tens of thousands of years of runway available to us today. We choose not to do it because it sounds dangerous and it’s not politically expedient.

For those unfamiliar, I am talking about Project PACER. The fusion reactor proposed by Teller after the creation of the thermonuclear weapon. It may sound fanciful but it’s based on a simple precept. We can already induce fusion reactions, albeit in an unstable and explosive fashion. What if we took that warhead, surrounded it with a giant underground chamber made out of steel several feet thick, and let it explode while molten fluoride captured the heat?

Their work conclusively shows that this can be done, and that molten fluoride salts could capture most of the neutrons to prevent embrittlement. A single such facility could power the entire country. Oh and it could be configured to create Tritium in the process.

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

The project was terminated because it was "bound to be controversial" and
would "arouse considerable negative responses."

The math is sound. The concepts are sound. We could solve the comparatively minor engineering challenges and build one today while waiting on the the breakthrough needed for controlled, continuous fusion.
Frankly most crypto tech can be understood in an hour or two of focused reading. Understanding how it works greatly demystifies the malarkey out there and lowers your cognitive load when interacting with crypto nonsense. For this reason alone, and since the news is replete with crypto nonsense, it’s worth spending an hour or two. If you already have a basic knowledge of computer science and perhaps distributed systems you’ve got all you need.

I am not particularly good at competitive programming, but at some point I did invest quite some time into it. Contrary to my username I have a pretty decent memory and I can remember easily if I've solved something similar.

At some point I've interviewed for a company who gave me four exercises to solve in an hour. Normally, it would've been impossible to solve them without previous knowledge. Funny part is that I knew the idea for all 4 and the only difficulty was to write things quick enough so I can finish everything in time. 57 minutes later, I was finishing all of them, to the surprise of the interviewers who were watching me coding.

I had the all time best score for that company, and everyone thought of me I am some kind of genius, which was certainly not true, because I know my limits, and I am far from it.

Nevertheless, everyone was a little disappointed by me in the next 6 months. I was quite junior, and had junior problems.
DB was still selling those tickets (as Schönes-Wochenende-Ticket) until 2019.
I agree. We lost two of our worst performers to FAANG companies. They were both junior and came from top schools. Communication was a huge problem and both wrote very sloppy code. We would assign trivial tasks to them that would take an average developer 30 minutes or less and they would struggle even with heavy mentoring. I was the mentor for one of them and I really tried my best, but there was little improvement over several months and luckily they moved on.

Now I'm mentoring two devs who didn't study CS in college and only completed a coding bootcamp and they're working out amazing.
Will Starship Really Revolutionize Launch Costs?

Very well said.

To the OP: if you really are a good programmer, then mastering LC is just a matter of time and effort and really, the problems aren't that hard. You're also hired at most companies to solve problems; not just be a code monkey. It's a matter of interest and motivation not whether you're good at LC or not.

LC is the best proxy we have for aptitude and general problem solving ability at this time. So best to suck it up and grind.
>Then simply add those hours spent estimating things to whatever time management solution that you use personally (for insights into where your time goes each quarter/year) or that your company mandates (for basically the same thing).

Which sometimes means it doesn't happen because it's not valuable enough at any given instant to go through that multi-hour process, yes.

Lightweight tasks exist. As much as I generally agree with you, following your rules means you either do not ever do them, or you bloat them to multiple times larger than necessary. And correcting a company's task-management process as a whole is not always feasible either.
> If America has dysfunctional healthcare there is still the rest of the world. Which might be good for Americans eventually as the tech will come across one way or another.

Which raises the question - why does the vast majority of healthcare tech development come from the US? (I included "development" to get around the out-sourcing of testing to China.)
Collectibles are going to suffer in a bear market, yes.

Thank you for your first-hand account! For someone attempting to innovate in healthcare from the outside, this is very valuable information.

If you get the chance, what would you say is the biggest problem/limitation/shortcoming/annoyance associated with these handoffs?
I agree. A lot of these are not industry exclusive to tech/SV. However, we take it a bit further at times and more importantly we advertise that we're different. We like to think we're different. Other industries don't try to act like they're different. You go into law, biz, med, etc... You know what you're signing up for. You need to be a little brown nosing subservient ass hat - and everyone knows it. And everyone knows when you get to the top - you get to subject everyone everyone else to your whims, your hazing rituals, and so forth. They know that's the reward for getting to the top. Boss says you do X even if it's unethical to ask - in other industries you do it anyway. In SV, we act like it's okay for you to question it even if your boss will still fire you for insubordination.

The difference is subtle but it's that SV at least tries to act like it's different even if they're not. That's what rubs me wrong about this industry the most. The virtue signaling without any real actions behind it. It is truly ghoulish.
