I lived 10 years off grid in vans and rvs, and now I mine bitcoin and charge my teslas with offgrid solar. I have built systems with every chemistry, even lithium polymer and LTO. And FLA and AGM. I have a lot of experience in this realm. It does not sound like youv'e seen my videos before.

Lithium packs are not a nightmare to recycle anymore. There are huge corporations fighting to recycle them now, and the tech has improved a lot. I could not say this two years ago. Lead acid is easier to recycle, but the cycle life of those packs, and sulfation you have to deal with, make them horrible for the environment. Cycling them deeply kills them fast, even the expensive ones. If you do not cycle them deeply, FLA will last for decades, but will cost a lot of money , space etc. And you need to maintain them. Lithium ion chemistries such as LiFePO4 are far superior.

I think you need to get your hands on some cells and actually build a pack. Test the coulombic efficiency and usable capacity at various temperatures and you will be blown away. And you will save a ton of money over lead acid. Lead acid is very expensive, and I would make a lot more money if I sold them. I also do not sell anything on that website, it only has affiliate links. I am not on any sponsorship contracts or have loyalty to any company. Most of my review videos are me bashing design errors and various solar companies. I do not think you have seen my videos, going by your comment. It is a little bit cringy, unfortunately.
Here is a true statement: "I speak English and have black hair, like Keanu Reeves. I'm looking into growing a beard."

If, based on the above, I were to tell people I looked like Keanu Reeves, would you consider that a reasonable claim?

BTW I'm not deriding your efforts. I'm just saying there's a big gap between 'setting up my first email server with webmail and IMAP access' and 'setting up something with the features and reliability of Gmail'.

I’ll take a look into this ta - the only thing really lacking in this setup is a UI for webmail or admin
You are absolutely right I have taken to referring to that as “notebook code.”

I love jupyter because its a great interactive programming environment that speeds up building scripts. But jupyter notebooks always end up being…notebooks. They are records of past work and thoughts that I had but I wouldn't present my paper notes to a coworker as finished documentation. I always end up extracting those jupyter snippets into runnable scripts and then I end up doing a lot of the work all over again as I parameterize things.

I have taken to using pycharm scientific mode and adding “cells” into my scripts: https://blog.jetbrains.com/pycharm/2018/04/pycharm-scientifi...

You get the interactivity of jupyter with the cells, the scientific view for plots and data, but you’re also writing a real script so you can still maintain some sanity in your code and good git history (and hopefully add some tests).

Then I combine these scripts together into a makefile and voila quick, easy and maintainable scripts. If you just stick to make, python, pandas and bash any programmer can modify your pipeline without needing specialist skills. I have written scrapers + ETL in <1.5 hour (journalist needed some data quick) with this method.

God I wish I still worked in data science I’m currently a front end dev and don’t get to do any of this at work. It’s such fun and offers so much room for creativity and problem solving.
> Batteries are not different.

Cost is.

Batteries degrade over a fixed amount of time, no matter the measures taken. A traditional, well maintained engine would last far longer than a battery, and the repair costs are usually amounted in a gradual manner, i.e. traditional engines don't usually require large investments to keep running, but EVs do.

In other words, not many people can afford EVs in the long term right now. Hopefully this will change, but the current state of things is what it is.
And this is how it should be because bailouts are done with our money, which means the public need to have some level of control over them afterwards.
Music and art existed before currency was a thing. It will continue to exist as long as humans exis.
Anti-LaTeX, Pro-Word paper corrections for “sizing and placement of the figures” (2015)
Does the Word comparison include spending hours fiddling around fixing indentation, formatting, and headers in 10+ page documents? When the whole document becomes a patchwork of conflicting formatting so any change you or any collaborator adds has some incomprehensible default that you thought you purged from the document weeks ago? The time spent merging changes made by 3 people at once and emailed around with document names that have no coherent pattern, where half of the time you can't even tell what changed?
I stayed at my ex's flat in W2 around twenty years ago, the estate was selling 2-beds for 240K then - are you suggesting those flats are over £1M?? I dare not look at prices.

Edit: Reader, he looked at the prices

Found almost identical flat at 499,999K, so coming in at less than Millbank flats were going for in 2016. Those flats are only £25K more now. This seems perfectly doable for software engineers who have a good permanent job or are contracting.
Your complaint here isn't about repair, it's that battery chemistry isn't a user-servicable component[1]. You have to buy a battery from someone. It turns out that packs are complicated devices and hard to replicate. It's not that Tesla has some kind of insidious DRM on their packs, it's just that there aren't any third party sources. There probably will be eventually, but there aren't yet.

This is different from the world of piston engines, where a talented machine shop (drawing on a century of evolved conventions in engine and vehicle design) can make replacement parts for basically anything.

[1] Potentially you're also complaining about price, because replacement batteries for a 2013 Model S are competing in a market with new parts for a car that retails for $140k. Replacing an EV battery is expensive for the same reason that EVs are expensive: the market wants more than the manufacturers can provide.
Presumably once this is broadly deployed, flight checks can be performed to check for interference.
What claim about plants in this article wouldn't apply equally to purely artificial mechanical things we build?

Most important in these times is to not get influenced by ubiquitous advertisement. Be that radio ads, youtube recommendations or highway billboards. One needs to be really careful to not let their subconscious get influenced. I personally make a list of most of the ads I see and don't buy stuff from those brands unless there is no alternative.
I live in bangalore. I found the ad ban extremely irritating, because they took down the billboards, but left torn cloth or plastic sheets in place! It even empty boards. It was looking so ugly everywhere. I'd rather see the ads. At least advertisers try to make their billboards look aesthetically pleasing. I do agree that it becomes excessive in some places. I feel that public (taxpayer funded) infrastructure should not have any ads.
Rephrasing, how will these patents be licensed?
I think you may be comparing Apples to Oranges here. Battery is to a Tesla what Engine is to a ICE Honda. Try asking Honda Dealership to fix a non Honda Engine that's started acting out.
What makes it particularly brutal, to me, is that the failures are typically silent. If GMail starts spamboxing my emails, I don't get feedback about that. If I'm not getting emails, I don't get feedback about that.

You can script checking those, but you'll have to re-implement it for each provider. And there are some that you can't; if I'm applying for a job, they're not going to give me an email account to test whether my stuff is deliverable.

HTTP services are absurdly easy to monitor in comparison.
Saying most mental health professionals are a joke is perhaps a little harsh in my opinion, after all they are trying to understand and treat the most mysterious and complex things known to man.

We don't diagnose diabetes with a list of symptoms because we have a lab test (where we have picked an arbitrary value, but that's another story). We have no lab test for add. That is frustrating, and I think that adhd is probably overdisgnosed, but I think most are doing the best they can.
The article doesn't really elaborate that well on the inflection point, that is where the author nearly doubled an already six figure salary while also making a career change.
What's different in the US from the rest of the world that's been running 5G for a while?
It works perfectly yes. Maybe it’s not fully blocked, or DO restrict the amount of traffic over :25
Nice selection of movies. Seems they could have included many, many more, but this is a nice list.
They do not need to stay that cool at all. When used for solar, the C rate for charging usually never exceeds .2C for overpaneled systems. And usually never goes beyond .5C for discharge. So the heat generated is very small. Now when I am pushing 30-100C rates with a lithium polymer, cooling is an issue. this is why nissan leaf cells were recalled. The battery size was too small for the application, and they overheated which caused significant degradation rates. This is not an issue for solar. Just keep them at room temperature and they are fine.
"Economists" disagree today, though, regardless of how strong their agreement was 60+ years ago. It seems unfair to the scholarly argument to pretend it's not there.

Saying that economists figured it out is a bit like saying "doctors figured blood-letting out 200 years ago". As true as that may be, we know today whatever it was they figured out is complete garbage.

What am I missing?
Find an interesting open source project with active and friendly maintainers (this might take a bit of looking). Figure out how to check out and build the code, then choose an open bug and fix it (or find a small open feature request and implement it). This will require learning how to read code in a bigger codebase and make targeted changes, which is basically the first thing you need to be able to do as a software professional.
First you have to make an important distinction, one that seems oddly difficult for many here on HN - you have to decide if you are earnestly committing time to this project *to make money*. If that's the case, now your time has value and you have to actually figure out if an audience exists and furthermore if that audience (which may or may not exist) is actually willing to pay for your solution. I chose the word solution because solutions implicitly derive value, a new note-taking markup or photo sharing app does not.

The second step is to field your solution and see if people are happy with the problem you've solved. Marketing is also a concept far too often underestimated or overlooked on HN. For instance, I wrote some software based on complaints from a very specific diy agriculture subreddit. Once I reached a bare minimum MVP I posted it on reddit, people were excited because a cool tech thing solved a problem they had. They shared with their non-internet friends and orders / emails started steadily flowing in. Unfortunately, the time/revenue ratio wasn't good enough and I basically broke even on the project.

That said, think about the problem deeply before spending valuable time "validating" what might be a solution nobody actually needs.
I have lived in both cities. This is accurate.

In LA, I think the issue is that people drive the exact same in the rain. There are no adjustments made to speed or space for braking.

It seems like it's going to affect a relatively narrow niche.
Let me add

1) get a prenup before marriage because there's a 50/50 chance you'll lose half in divorce (at least in California.) This is not very romantic so it's not something I ever considered, but it's recommended to wealthy persons by lawyers.

2) don't become an alcoholic or drug addict. If you think you might be developing a problem, own up to it, seek help and go to rehab if necessary. This includes gambling addictions. A cocaine and gambling habit is probably the quickest way to become broke again.
What "alternatives" would you to be given? It's not Tesla's job to fund outfits to make replacement batteries. If no one is making them then no one is making them.
Why didn't he just replace it with another third-party battery? I'm guessing that there was more firmware trouble that severely impacted the car.

No, I won't be buying one of those, and I will be keeping my Honda as well.

The multiple views of the explosion will probably follow Tesla for the next decade, which they likely deserve.
Some concerns with this study:

1. 40 is not an adequate sample size. Not even close.

2. Continuous text entry in LaTeX and Word is very similar, so why are LaTeX users far behind Word users here? Did the researchers measure typing speed and control for that, so that the Word group wasn't given a set of typists who were, on average, faster?

3. For the equation entry portion, did they control for user expertise when assigning participants to groups? e.g. Asking a psychologist to typeset a physics equation is going to result in slower work and more mistakes. With a sample size of 40, an imbalance of just a person or two could easily throw the whole study off. (Note: They did find that LaTeX was better for equations, which is not surprising. Their methods are still suspect though.)

4. This study does not address the specific tasks most people use LaTeX for: papers and books. Both are longer than a quick and dirty copy job, and such jobs benefit greatly from LaTeX's ability to produce consistent output when edited. Word documents break in all sorts of strange ways once they become long and complex enough.
DeFi is money legos. This is the stuff that traditional finance does behind closed doors every day. The fact that we get to see it out in the open now (with open source code), is amazing. It is a lesson in core financial economics.

Surely there's a better medium for long-term storage than paper? I can see this working for small documents, but if you have to print out thousands of pages you mine as well store the data on some kind of USB and maybe just print out the key shards.
Well...certain areas. I myself get excited when it is snowing and I get to drive.

Seattle tends to lose it's mind when there is barely any snow...but as soon as you get past Issaquah people start driving like they have been in snow before.

I remember one trip coming over the pass maintaining 50-60mph with a ton of snow...but as soon as I got down the hill everyone was driving 25mph on the freeway.

Mostly the PNW communities inland have it together when it comes to snow. Aside from certain areas such as Tri-Cities south to Umatilla, Columbia river gorge and the mountain passes you can typically expect to at least be able to get to your destination without issues. Central Oregon (HWY97) uses what appears to be crushed lava rock on the highway...which is quite nice.

From what I have seen though...the coastal areas (or any area which doesn't regularly get snow) people, cars and road crews are not prepared for what happens when it falls.

I live and grew up in North Idaho...outside Spokane. Snow driving is just something you accept and learn to prepare for. If I lived in Portland though I would likely stay home. It isn't "my" driving I am worried about. It is the person who has near 0 snow driving experience, and/or in a car without proper tires and maintenance that is going to be the issues.

At night you should never outdrive your headlights...in winter you should never outdrive a reasonable stopping distance. If you are not prepared or comfortable operating a vehicle in the snow...don't drive for a few hours or even days.
I discovered Telegram video calling on iOS has a convenient screen sharing function (accessible when toggling a switch between front and back cameras). Gone are the days of asking grandpa to try to show me his iPhone screen over Skype (And trying very hard to read blurry and moving text).

That's a big if. Looking at the current situation I predict Apple/Meta/Google will own "your" AR. Just like with smartphones.

That has nothing to do with your statement "consumers are forced to buy cars as services" which is hogwash.

The people taking these roles arguably aren’t contractors anyway. The market in the uk for contracts outside the legislation is healthy.
Compound interest wasn’t the key here. The key was salary increasing rapidly and the 600K+ salary at the end. He could’ve not invested at all and still gotten there.
For me personally, one of the most effective means of knocking out the first 95% of spam was using the S25R regex methodology [1] created by Asami Hideo which seems to keep the load on SpamAssassin and ClamAV really low. I've had to adjust the regex rules over the years a little bit but it's really low maintenance for my setup. There are also lists of IP addresses and networks you can block that are known to be malicious which also reduces the load and log volume. [2]

Agreed, the geopolitics was very simplistic. I was always looking forward to the next space scene.

I also read Ministry for the Future which was pretty heavy on politics. It didn't grab me the way Project Hail Mary did, though.

Banksy is talking about moral right, not legal right. This is obvious unless you're being intentionally dense. He is saying that you have cosmic permission to perform acts of vandalism to advertisements. As long as you don't get caught, you're alright with your chosen deity or whatever.

It's a pretty strong philosophical argument in that direction, in my opinion.

If you're disagreeing with that point, you should be explicit. You're arguing that these companies are paying for the advertising, but they aren't paying you to throw the rocks at your head, they're paying the building from which they obtain their vantage point. I don't think that actually qualifies as "paying for it", morally.
Perhaps Fed QE, with artificial suppression of lending rates(if I understand it correctly), was akin to leaving kindling around, but without the spark of a global supply panic, there wasn't a sure bet for traders to leverage. Once it seemed clear that prices were heading upwards due to supply shocks, it was a no-brainer to use the cheap money and drive up the prices of assets even further.

I'd also add that the helicopter stimulus from the government probably helped goose asset prices as well.

I don't know... if you listen to some folks, QE is deflationary because it traps money in the financial system. I'll say that I personally pulled most of my money out of the market in late 2019 because I already thought we were due for a correction. It seemed like, while it took a few years, asset prices were already climbing before COVID hit. The lack of inflation could be explained by increasing globalization and overall anemic economic growth(which is one piece of evidence used by the "QE is deflationary" crowd).
That is awesome

What I've learned from working with transactional databases
is how to deal with things like this.

You have a time in the evening, now that time
is blocked by your friend (they didn't commit
nor rollback). You can't process further because
of that lock on your time. The lock is unspecific
(there is no start nor end of time).

So you become anxious, because you need to route
things, but you can't do this because of the
undefined commitment.

There are several strategies that can work:

1. kill the undefined commitment (you can tell them that something came up, so you can be there no longer)
2. specify the bounds of the lock, so that it won't take everything (ask them again for the time and place, if they won't reply do the 1.)
3. Guess it. If it is a drink, then it is after work. Then how much it usually takes me to get there, do it + some padding in case something goes wrong. Basically you do the work on your side.
4. Discard all conflicts. (Tell everyone that you have an important meeting, so you will interact with them tomorrow). Now your whole day is waiting for that meeting and nothing else. In some circumstances it is the right way to go.
5. Optimistic scheduling. Schedule everything to the best of your ability. If something conflicts, kill or reschedule the less important thing. (I am sorry, but something came up, so I can't be there today, maybe tomorrow?)
6. Simply wait. As the day progresses you will get more information to make the right choice
