In Canada we have a tax free savings account that lets you invest about 6-10k a year entirely tax free (it varies from year to year). The issue is that it does not allow you to leverage your investment or use margin. So to get around that every year I dump my entire 7k into TQQQ and UPRO 50/50 and have done so since 2013.

I don't see why this would be a bad idea and this article seems to be fairly poorly written. In general there is nothing wrong with putting some of your capital in a tax advantaged account into a leveraged ETF. No one is suggesting to dump all your savings into it, but putting some ratio of your earnings into a leveraged ETF allows you to indirectly maximize your contributions.

I'd definitely prefer to use margin directly through my broker, it would be cheaper and less risky than an ETF, but the law is not setup to allow me to do so in the various retirement or tax advantaged accounts, so instead I use this as an alternative.

For ordinary investment I think using some leverage is smart, especially if you're younger. Take something along the lines of 2-2.5x leverage until you're in your 40s, then start scaling it back as you get closer to retirement age.
Where should one have been paying attention to hear about this conference before it started?
> Only from a human perspective are humans something other than natural.

I don't think that's actually true. Any alien observing the planet over the last 4 billion years would recognize us as an anomaly.

Polluted cities, sucking in value from all around, at the cost of countless species have often been compared to cancer. The aliens might see things similarly, with their large dispassionate eye and tall perspective.
Very rare in history has someone or group acquired power and willingly gave its up.

CDC was never a major player before. Now they control millions.

Not a chance they will ever give that up by choice.
M1 Max Macs that have enough memory and processing power to be a mobile workstation can use their battery in 1 hour if running at 100% CPU usage so if you need all that performance then you will still need to be close to the wall power outlet.
If you don't need all that performance then there are other laptops (not Apple) that can last long enough between charging too.
M1 Mac is currently an excellent laptop for regular users but real power users either have to be close to the wall or use desktop CPUs to run their workloads...and no, web and software development does not require a lot of CPU power, I know, I am a developer and I develop software for people who do need to run 100% CPU for hours and hours and M1 laptop will not last them any longer than the i7.
The Japanese country side isn't too different than the US. Sure there's trains, but not an extensive network ala Tokyo, and you drive everywhere.

The way they handle the issue is "daikou taxi", which is a service from the taxi providers. If you've been drinking, you call them, they send a taxi with 2 drivers. You get in the taxi, and the other driver drives your car home.

Introducing a service like this would help reduce DUIs, I think. Having stricter laws about also helps avoid people making the decision to drive somewhere, where they know they're going to drink, in the first place. Instead they may opt to take a cab, find a designated driver etc, drink closer to home etc..
I hope you realize you're one pebble or pavement imperfection away from breaking every bone in your body at those speeds.
Leveraged ETFs, which aim to deliver leveraged intraday returns, don't mirror a leveraged position over the long term [1]. In particular, the more volatile the market, the worse the leveraged ETF's returns will be.

My point is that enforcement is very scarce, otherwise all these phone scams (whether credit card, IRS, tech support) the US is constantly being assaulted with would no longer be so endemic.

The argument is that crypto allows criminals to get away therefore let's ban crypto. Well, the real world shows that criminals are equally allowed to get away by conventional payment systems.

I'm generally not in favour of banning crypto, but at least they'd have a point if the traditional banking system actually prevented financial crime. It clearly doesn't prevent it anywhere near enough. If anything, the complexity of using crypto for the average user means that a traditional payment system scam will yield more than a crypto scam.
Pardon if this is off topic, but do you have any tips or resources on how to get into PalmOS programming in 2021? I have some archived SDKs and got prc-tools working but have yet to wrap my head around how to actually get a simple gui going from scratch
Even after the Perl 5 / Perl 6 / Raku debacle? Many developers left after that (Python pulled off the same trick a decade later.. apparently some language teams have very short memories.)
Written language usually don't have paragraphs inside paragraphs.

In programming things are frequently nested several levels deep.

This is the key difference that makes a termination character/word important I think.
Interesting. My company is in the immigration space and we were considering a product to help distributed remote startups to organize group "off-sites". If you'd like, please reach out on the email in my profile.
This isn't click bait, it's what happens when a maintainer gets the same question 100 times and feels the need to publish something publicly so they don't have to keep repeating themselves.
The interviewer, at the end of the talk, almost touched an important and fundamental aspect of what Google is doing. In fact, what everyone who's working with machine learning is trying to do:

Who gets to decide what view of the world is normal and acceptable by everyone?

The problem with this question is that no matter how one approaches it there will be a part of society (or even between countries) who's going to be left out[0] or will have to adapt to this new way of thinking (or how the model performs)... And at that point we have to ask ourselves: are we being really ourselves or are we being modeled after the sum of the outputs of all machine learning models out there?

When Sundar Pichai said AI is more profound than electricity or fire[1] he wasn't just making a public relations or marketing statement.

There are two points in the comment. I went with the easier one to respond to, because I don't feel like the parent is entitled to asymmetric labor in the form of a detailed rebuttal. The Internet really is an incredible place.
Maybe!

They could drop a bunch of high-value resources and information at that URL, and then also have a nice big button to go to the business site and play it all off pretty nicely
No you do want it, but not to buy and hold for months at a time, you should buy and hold for a few days and then get out after it peaks. You also want SOXL, FAS, UPRO/SPXL, URTY/UWM and TMF and want to operate on these the same way. The key is to know when to buy and sell these. The easiest is to use Price Headley's acceleration or Bollinger bands. Buy when the price falls out of the band, wait for a green candle on the daily and go in big, the next day might be red but you will be positive after a day or two. Sell when it hits the top of the band and there's a red candle.
No, it was directly in the shoulder joint, like a rotator cuff injury.
As other people have alluded, the solution is to not join the brutal open market for entry jobs. Find a path via internships to an entry job, stay for some experience, and then compete outside the entry market.
The “charge to 80%” advice isnt generally useful to PEV riders in 2021

It is true that a lithium _cell_ lasts longer when charged to 80%, but a _battery of cells_ must be “balanced” and PEV BMSes only do that balancing in the constant voltage stage of charging in the hours after the charger indicates the battery has been fully recharged.

For anyone just learning about this, an unbalanced cell is usually the cause of a battery going “dead” and can even be the cause of a fire. Very few batteries die because they have outlived their charge cycle count.

This is different than your cell phone which has at most two cells (but usually one) in the battery. In that case, the BMS can monitor and charge individual cells. In a PEV the BMS usually monitors several groups of cells, and can not charge individual cells.

This can change in the future! I believe electric car BMSes generally do it. But its an added expense and PEV manufacturers have not started spending the money. Ill be happy if another commenter can correct me and show that there is some manufacturer who is ahead of the curve.
I built something like this when I was in college for a project based course. I used 8 small vibration motors and made a strap you could wrap around you leg. I connected it to a compass and had the north facing motor always vibrate slightly. My plan was to use it while riding my motorcycle to give me an ever present sense of direction.
I think the key difference here might be that you were on vacation. I assume those going to work or school would feel the effects differently.
It's way off topic. The Q-and-A here is are about getting actual legal expertise applied to questions, not opinions about how US immigration law is flawed. You're not wrong to say it, it's just that this isn't the place/time.
Yes so that's a dream. But at least one can offer the option NOT to update unless absolutely necessary, which some apps don't even afford or difficult to do so.
> The idea that mathematics is "the language of the universe" that can be precisely "discovered" by brilliant minds is a ridiculous notion

This claim is at least as speculative as any claim that the universe works on some symbolic system.
It's almost impossible to avoid soybean oil in the US. Higher quality foods tend not to have it. I have a family member who is unable to tolerate soybean oil, and that has led to healthier food choices for all of us.
Thanks for the info. I have zero tolerance for bs so I really value being able to leave.
Because it is about power and control.

Themis | Senior Rails Engineer | NYC (HQ) and/or Remote (Anywhere between Texas <=> Ukraine) | Full-time

Governance of fintech doesn't have to be an obstacle. New finance companies need tools which simplify governance on a daily basis to help them focus on their platform's core value.

Our goal at Themis is to streamline recording and sharing of the information necessary for a company to demonstrate their governance is solid. The companies most in need of a tool like Themis include new disruptive companies in defi, crypto, and neobanks and established players community and larger banks. Effectively we're putting governance information on rails for companies who previously had to maintain large teams of employees to meet these strict requirements.

We have seed funding and are in pilot testing with our first customers. Read about us at https://www.askthemis.com

We're seeking a senior engineer to join the founding team to lead the engineering effort, provide guidance on architectural choices and deliver new functionality.

We're also seeking junior engineers who are looking for rapid growth. We strongly believe in mentoring and helping team members grow to their career goals.

> I thought of stop riding bikes, but then chose to have a life insurance instead

This is how i treated cars, but it feels backwards. You're made right after the accident, but you're already dead.
A particularly interesting story and well presented.

Also, this was my first time hearing that JP Morgan was suspected of being involved in the theft of the Mona Lisa.
Only the winners get to write history. Early computer history has been rewritten to remove all mention of Commodore. They were the true pioneers of computing in business and the home during the late 70s and early 80s.

Apple's revenue through the 80s and early 90s was from the Apple II and when that revenue dried up then Apple cratered. Apple never managed to be profitable from Mac revenue until the late 90s to early 2000s, which was a good 15 years after the first Mac.
The article is written by someone who regards their habit as a problem, and, without knowing anything about it, you try to minimize it.

"Why quit smoking? If you're smoking this much, it must bring you great joy!" You don't seem to understand how addiction works.

The fact that it's not scientifically proven that compulsive browsing is harmful was explicitly addressed in the article. That's a problem.

In my opinion, the biggest problem with compulsive browsing is that you give up a proactive design of your own free time. You hand over all decisions to the algorithms. The only decision left is whether or not to open up a thumbnail. It's a slot machine, it's gambling. For a laugh, for entertainment, for the next dopamine hit.

"Why quit gambling? It's only a couple minutes every night, and you have so many minutes left."
Boeing U.S. worker vaccine exemption requests top 11,000
Of course not, hence why I said I would in principle prefer to use leverage directly. But as the laws do not permit me to do so in tax advantaged accounts, leveraged funds are the next best thing. But I certainly would not use a leveraged ETF outside of such an account, it's both cheaper and less risky to use leverage directly from your broker.

Do you know if U.S. retirement accounts allow the use of leverage? I am aware of Roth accounts and perhaps some other types of accounts that Americans can use that are tax advantaged. Do they allow margin accounts?
A tiny pet store fish became the center of neuroscience research
At some point you’re stuck with a bunch of equations that work and the only way to make progress is to try to interpret the equations.

> Electrons aren't little hard balls, which is why they don't rotate, and this is why spin isn't some huge mystery.

This doesn’t clarify spin at all. Spin is actually incredibly weird and anyone who writes it off probably doesn’t understand what’s interesting about spin quantization, spin/angular momentum noncommutativity, fermions obeying SU(2) instead of SO(3) rotation characteristics, etc.
Don't be ridiculous. Shorter days make everyone miserable, clocks going forward/back is pretty irrelevant as a change of itself and most people never notice as their devices sync automatically.

Let's try to make the most of the sunlight - personally I'd like lighter evenings, but then I appreciate others may prefer to have more sunlight in the morning.
> Any alien observing the planet over the last 4 billion years would recognize us as an anomaly.

An anomaly, sure, but they could very well view us as a natural anomaly. We're talking about fiction now and there's plenty of fiction that runs along these lines (aliens view humans as humans view other animals).

Not a great sign when your worldview is exactly the same as the villain in The Matrix...
Super-resolution has been in the news over the last few days after it came up in the Rittenhouse trial. The defense lawyers said something along the lines of disallowing the ipad pinch-and-zoom as a way to present evidence because (they claimed) that it does super-resolution, which would potentially introduce fake evidence.
If you have lot of client sources (say in each micro service) different languages and frameworks connecting to same server ( perhaps different db/schema ).

It is easier then to manage it in one place . Also dynamic scaling of server pools etc you need change the pooler config instead of every application.

And postgres connection management(open/close) is expensive, if you can handle it outside the the db infra it can be beneficial ( only some client libs will pool their connections and others won't). Even with client pooling support in the library, each container/forked runner will have its own connection, and that can be quickly few hundreds.

Finally AFAIK most libraries don't handle master failover or server restart without crashing the connection, pooler will usually keep the upstream open for some time.
At those speeds bikes are incredibly stable. The only way a pebble of pavement imperfection will harm you is if the bicycle fails mechanically (e.g. a wheel folding in on itself).

I'm pretty sure that the risk of being hit by or hitting a vehicle is multiple orders of magnitudes higher. Which isn't exactly better, but let's at least worry about the correct sources of danger.
Van Moof is my favorite, because bikes are stolen a lot where I live and Van Moof comes with an alarm and GPS.
Or maybe we have too many developers that treat language of their choice as a religion.
> I then discovered how dangerous this can get

Presumably this has nothing to do with biking and everything to do with other motor vehicles?
I think you need citations for everything you wrote there. We do have a lot of research into how people come to believe conspiracy theories and (to a lesser extent) how to break them out of it.

Most of what I've read agrees that pushing those people and/or treating them without empathy is the wrong approach. But the cause is not always contrarianism, and vaccine skepticism is not a perfect analog for the other controversial issues you mentioned. Tellingly, vaccination wasn't a political or controversial issue for many decades in the US.

>Google it. How many people have sleep problems? It’s a very large number. The effects are certainly in the billions, given the health impacts associated with sleep problems.

That's neither here, nor there. The parent didn't ask how many people have sleep problems, but how many people have sleep problems because of the DST, and even more so, problems that last "2 to 3 weeks" as the article claims.

People have sleep problems for all kinds of reasons (apnea, stress, weight issues, checking Wikipedia at 3am and so on).

I suppose it's a "pathway to perl" in the sense of a mild gateway drug. Perl is definitely one-liner-friendly. Every time I get into Perl I have to relearn it all over again (which is apparently not an isolated phenomenon), so I don't have great suggestions for digging further. I just habitually reach for perl -pe about 3/4 of the time.
> But why save pdfs instead of downloading the webpages?

Ages ago we had this wonderful format called MHTML which allowed you to save an entire webpage (with images and all) as a single file. This was amazing for archiving and I remember saving lots of tutorials in this format.

But the format seems to have fallen out of grace over the years to the point where it became difficult to find a browser that allows opening those old files.

PDF now seems to be the best method of archiving content. Standards like PDF/A implement a subset of the PDF standard which ensures the content will be available for the years to come.
Some examples:

FOUO - A doctors patient list. That isn’t the business of the public and should not be released. That data does not contain PII, patient health data, and is not protected as a matter of security but it is still protected data.

Classified - Data that is restricted from public release. This is lowest level of protection and is intentionally vague.

Secret - Information that if disclosed can be used to harm people or disrupt government operations by adversaries. This includes information like convoy travel schedules and communications outages. Secret data is typically really boring office information in otherwise more exciting work.

Top Secret - This information, if disclosed, will likely result in embarrassment to the extent that national security or diplomatic relations suffer or that the intentional imminent danger of death or bodily harm occurs to people.
I have looked into this topic off and on -- The laws of slavery from the slave-holding States, were absolutely a source of conflict and included in the first shots fired. There were trade issues and disagreement on monetary policy (no single currency yet?).

At that time in US history, multiple large land acquisitions (new states) were in progress after the massive land sale by the French and the repeated defeat of the Spanish in the Far West. Modern Texas had been finalized and the US Presidential Election had regional candidates competing vigorously.

The civil war famously was not very bloody for the first year, with a lot of arguing more than shooting, but neither side stepped back, and the restriction of navigation on land and water led to more battles.

This feels like a weirdly one way decision. As in, this policy is not one they can be undone by legislators who disagree because they’re excluded from voting by the same policy.
For most types of code, other than things like code which has dependencies on implementation internals (like extensions in SBCL for instance), or uses FFI to access platform libraries that didn't exist in 1995; that sort of thing.

ANSI CL was last ratified in 1994; there has been no standard language change, and the community language improvements are just macro libraries. You should be able to take your alexandria utilities library, or optima pattern matching or whatever back to 1995.
The article has some misunderstandings about idiomatic ruby imo.

> Ruby keeps going with its methods-first approach, except instead of each we have a new set of methods commonly implemented on collections, as below:

And then you show map, select, etc being re-implemented.

But once you have "each" defined, you'd just include "Enumerable" and get all the others for free.

As a separate point, I almost never implement each on a custom object in ruby. There are probably "library code" cases where it's appropriate, but in day to day work it should be rare. Typically I'd put objects in an ordinary array instead.

Nit: Ruby style guide (and most experienced code I've seen) never uses parens to invoke a method with no args.
Europe will be hell this winter. The inability to maintain the lie that restrictions were worth it because "we were waiting for vaccines" will mean that they have to scapegoat "the unvaccinated" even harder.

No law, human right or ethical qualm is to be considered. Just hate and blame because authoritianism and segregation is what we've always wanted and needed. Personal choice is a sin.
