Some of the skills tested in the study seem more like arithmetics rather than financial skills:

- "About a quarter could not work out how much change they should receive from a shop..."

- "About one in three adults struggled to work out the price they had to pay.. per litre or per kilo"

- "About half could not read a simple financial line graph"

- "Most struggled to calculate discounts involving more complex calculations"

I mean.. people can't do math in their head. Who cares? In my opinion, the most important financial skills are simple things like monitoring your credit, your spending, creating a budget, pay off credit card in full, pay down high interest debt ASAP, avoid pay day loans, don't spend money on stupid things, invest in high quality index funds, etc.

These skills are mostly psychological and will help your financial health WAY more than calculate price of chicken per pound in your head.

So a bunch of centrally controlled monopolies agreed to realign their offerings to maximize profit and gain greater control over end-user.

They also pretend, that compromising 3-months certificate is "ok" (or at least less harmful, than compromising a year-long certificate), when in practice there is no reason to assume so, — 3 months is more than enough for any real-life eavesdropper.

Science might not have a perfect understanding of Earth’s climate, but that really isn’t the point. The point is we can detect when humans are behaving in ways that make Earth less hospitable for humans and we can then choose to behave differently. Air quality in Los Angeles is one practical example. We’re not perfect, but we also stopped aggressively poisoning ourselves.

> If someone does dispute this and provides some evidence to the non-veracity of GR and QM, what is the likelihood of them even getting published in any high profile journal?

100%. They will win the Nobel prize too. The operative phrase here being provides evidence.

> We have plenty of evidence across many fields where dissenting voices are shouted down and are called "crackpots" because they don't follow the consensus view. Some of these even get the Nobel Prize decades later for what they were condemned for at the time.

Yeah? Like who?

> All theories (and I have found none to the contrary) use some form of simplification and assumptions

Yeah? Like what?

You keep making this claim, and you keep not providing any evidence or examples. That is the mark of a crackpot.
Couple of years ago I had a colleague who was obsessed over getting his name on Wikipedia. So he had someone add a page for his town. Then he edited the page to include about how he was the star captain of a local league. To play a practical joke on him, we edited the page to remove his name. Soon it devolved into a cat and mouse game of editing and re-editing the page.

I don't know if wikipedia now strictly monitors page edits. But, if they don't I hope Youtube also adds a big red warning on the page - Do not believe everything on the internet, even if it is wikipedia.
I agree, especially in this kind of study, where it's been acknowledged (e.g. https://www.tandfonline.com/doi/full/10.1080/09658211.2017.1...) that lies contribute to the formation of false memories.

For example, another commenter reports that his mother seemingly remembers things that never happened; the first thing I thought (because of similar experiences) was that perhaps his mother had lied to friends about family coming over to visit.
Interesting that two "heavy" CMSs, SharePoint and Drupal, top the list of most "Dreaded" Platforms (Section II., 4th item after Languages, Libraries, and DBs).

I can see a number of reasons for this: (1) The new trend is toward the simplicity, security, speed, and flexibility of the JAMstack and new CMSs like Netlify CMS, (2) The learning curve for big CMSs is steep, and (3) It's extremely challenging to deliver modern, mobile responsive sites with these heavy CMSs in the timeframe that stakeholders expect. Stakeholders chose a CMS because they thought it would deliver their site faster and cheaper than custom development. So the deck can be stacked heavily against developers using SharePoint, for example, unless stakeholders are happy with using mostly the out-of-the-box (OOTB) UX.

> some rocket configurations are inherently impossibly to calculate total dv for (eg, a lunar-orbit rendezvous mission a la Apollo).

I think this fact should be communicated clearly. After all, the game has a bunch of "sorta but not quite" indicators already - like the burn time in maneuver nodes, or the orbit display that doesn't take into account atmosphere when deorbiting/projecting deorbiting with a maneuver node, etc.

These aren't even "financial" skills but a lack of basic arithmetic ability. It is a failure of the education system.

I expect if we tested for actual financial skills the results would be even worse, as that requires some domain knowledge beyond basic arithmetic. I'm not sure this is easily fixable; most people I know have a very limited interest in understanding financial maths.
This is a really disingenuous submarine piece to sell consulting hours.

Blockchains are significantly more inefficient than traditional databases and open up unnecessary security holes if its using PoW or PoS.

Distributed databases with amend only and some sort of log (add a merkle tree and call it a blockchain™) would be more cost effective and efficient than any actual blockchain system.

However that doesn't mean that you shouldn't be able to either

Would be nice to be able to tell if something is allocated on the heap or stack in a portable way.

As in being able to ask if and object is thread local or not. The language and run time could support that but studiously does not.

Just like the language could allow you to directly monkey with the ABI but does not.

I would love if null encryption ciphers actually worked in real life, but they don't (for the same reason why plaintext HTTP/2 does not — everyone disabled them under political pressure).

By the way, — signing is not equal to "null encryption". Signing can be done in advance, once. Signed data can be served via sendfile(). It does not incur CPU overhead on each request. Signing does not require communicating with untrusted parties using vulnerable SSL libraries (which can compromise your entire server).

As we speak, your SSL connection may be tampered with. Someone may be using a heardbleed-like vulnerability in the server or your browser (or both). You won't know about this, because you aren't personally auditing the binary data, that goes in and out of wire… Humorously enough, one needs to actively MITM and record connections to audit them. Plaintext data is easier to audit and reason about.

The ethics of this move are quite questionable on Youtubes part.

Dumping a large cognitive load on shared volunteer infrastructure without some level of compensation? Not cool.

The fact that Youtube is doing this and is not:

* paying wikipedia for the service they are demanding of it

* offering wikipedia support in developing tooling to cope with the NEW TASKING that youtube is expecting

* talking to them about it before announcing it

Suggests that Youtube does not understand its own role in the media ecosystem and is exposing itself to systemic legal and moral risks that could have adverse effects on the company itself and possibly on the entire industry.

If someone gets to a Flat Earther video via autoplay ( start from watching aircraft videos.. ) are they better served by being directed to https://en.wikipedia.org/wiki/Myth_of_the_flat_Earth orby being shown a countervailing video explaing that the earth is in fact round and there's evidence and how to check it?

Does Youtube have a responsibility to help society stay within shouting distance of the reality principle? I think it does.

Do you?

I too am using a 2009 MBP. Installed a SSD ages ago and replaced the battery about a year ago. Running Mavericks. Good for browsing, emails, etc. Use a beefed up Ubuntu desktop system for serious development work.

Anytime I walk by an Apple Store, I test out the latest systems. The keyboards don't feel right for me. And the touch-bar hold very little appeal for me. When this MBP bites the dust, I'll probably get a PixelBook.
you assume that. But a lot of these slimy characters keep coming back, end up on boards of directors, or running for public office. It's almost a bad cliche now. It happens even when they get convicted and do time. Watch and see what happens to Shrkelli in 8 years.

Yeah - you trade it for the 250bar/3600psi storage pressure problem (compared to 8bar/120psi for LPG). It's also about 1/3rd of the energy density of LPG, so you need to carry a lot more of it.
My personal laptop is a Macbook Pro 2015 but for work, I've got an HP ZBook Studio G3 (i7-7820HQ/32GB RAM/256GB SSD) which is quite nice.

The ZBook is Windows 10 Enterprise but surprisingly, it's been not bad to use. I run the Linux subsystem which has come a long way since the beta.

My only real complaints are no support for hardware keys (ie if Git signs w/ a private key on your Yubikey) and, by default, no support for the open command. There's way to get it to work on the Windows partition but no dice for the Linux dirs.

There's quite nice interoperability too like the Linux docker CLI being able to connect to the Windows daemon. Annoyingly, there's a bug where it fails so you gotta restart Docker once on boot up.

As a CLI fan, all 3 flavours (Win/Mac/Linux) feel the same at this point. It's basically your pick of OS around it (file explorer/window chrome etc) if you ask me.

I like the Macbooks but as someone who has run one for a while, I kinda miss having a mobile GPU and like you mentioned, the slimming down of ports and that is a pain in the butt.

What about the 'Whales' ? Apparently < 1,650 Wallets (and individuals owning those wallets) possess over 90% of all bitcoin in circulation, and each has a minimum of 1000 BTCs.

These whales have routinely manipulated the market. Most recently on Feb 6th, when the Mt Gox Custodian dumped like 300 million worth of BTC and briefly the BTC price plummeted from 7Ks to 5.6K.

Same here. It took me going though 3 computers in about 4 years to see the point of paying more for good build quality. Installed linux on it. Unlike a mac it has an nvidia gpu so you can train neural networks on it (and yes it got hot enough to unglue the rubber feet from the bottom, but I'm still happy with it).

I agree that they are mostly unnecessary with only three people. But I'll have a stab at a blunt division of responsibilities:

- CEO: Main purpose is making sure that there is a company to run. Get funding etc.

- CPO: (I suppose you intent it to mean Chief Product Officer) Main purpose is to make sure you build a product that the market needs.

- CTO: Main purpose is making sure that the product can/will be build.
Great Choice. The laptop I replaced with this pro is a 2013 macbook air. It's served me well since the day I bought it, and I still find myself using it even though I have the new one. I've run linux on it in the past and IIRC it doesn't have any major hangups.

I probably wouldn't have bothered buying a new laptop in the first place if it wasn't for the low resolution screen. I find it awful to write code on, but the quality of that machine is top notch. Haven't had a single issue with it since I bought it.
> OOM tests are done in a loop. On the first iteration of the loop, the instrumented malloc is rigged to fail on the first allocation. Then some SQLite operation is carried out and checks are done to make sure SQLite handled the OOM error correctly. Then the time-to-failure counter on the instrumented malloc is increased by one and the test is repeated. The loop continues until the entire operation runs to completion without ever encountering a simulated OOM failure. Tests like this are run twice, once with the instrumented malloc set to fail only once, and again with the instrumented malloc set to fail continuously after the first failure.

That's pretty awesome actually.

>I’m extremely skeptical lyft is replacing anyone’s car. The “sweet spot” is cities, and you probably already didn’t need a car if lyft is all you need.

I got rid of my car because of uber/lyft.[1]

I'm in a "city" in that I'm in silicon valley[2]; Public transit here is woefully inadequate; before uber/lyft, calling a taxi usually took several tries and several hours. I mean, I knew one guy who rode his bike everywhere? but he was bothering me for rides all the time before uber/lyft.

Uber/lyft is often faster than driving yourself, mostly due to the fact that I don't have to worry about parking. But for me? the important part is that I don't have to worry about paying attention. I can sit in back and read or whatever; it's actually quite relaxing.

I now use safeway delivery or amazon fresh for groceries, and I consider that to be a pretty big improvement in my quality of life; I don't spend time in line anymore, and I get fresh vegetables twice a week.

As far as I can tell, not having a car and getting driven everywhere costs me about as much as owning a late model moderately nice car and driving myself; I've owned some nice cars in the past, but driving a nice car just doesn't compare to being driven, when it comes to comfort. It's like the most stressful part of my day just goes away.

>Meanwhile, leaving the city would be extremely expensive and unreliable with lyft.

Absolutely true. Same with hauling things. I rent a truck when I haul things, and rent a car if I want to go camping or something. My normal 'out of town' trips, though, I either take the train, (my parents live near Sacramento) or an airplane, and if necessary, rent a car at the other end.

I mean, I totally acknowledge that some people really enjoy driving and enjoy owning a car, but certainly some people prefer to be driven. I prefer to be driven. Personally? Uber/lyft could become between 1.5x and 2x more expensive before I seriously considered driving myself again. Maybe more, though at that point I would put more effort into optimization.

[1]I still have a motorcycle, but it's an old bmw; really my hobby is fixing it more than it is riding it.

[2]The south bay - really, it's more "suburbia" than city. If I lived in San Francisco or the rest of the area serviced by BART, getting by without a car would be a lot more realistic.
You wouldn't need to carry all that much for cooking. The storage pressure is a solved problem in cars, so it shouldn't be difficult to manage on board a ship.

I really want Ada to get its fair share of attention. It's an impressively well thought out language. It's like a team of academics and industry pros took a long hard at C and C++ and then made something to fit the the same niche (high performance, real time, and very important software), but made it almost impossible to write incorrect code.

Actually, that's exactly what happened.

There seems to be a slight misunderstanding.

What that means is that the particular Rx drug being advertised can only be advertised to consumers of that Rx drug in question. So insulin can only be advertised to people with diabetes.

The interesting thing about this is that it leaves most of the power with the HCP.

As for the delivery mechanism, there weren't too many options in the recent past, however, these days there are POC marketing companies like Outcome Health (and others) and a growing number of software applications are aware of their user's health condition / needs (with permission of course either explicitly or by virtue of the intended use, like apps for diabetes patients, etc.).
When did conspiracy theories become harmful? This seems like a move straight out of “1984”.

I too used to focus on money first. Eventually realised that it didn't make me truly happy.

I weaned myself off the money first way of thinking by reducing my living costs so that I could actually save some money, invest it in real estate. These days I can choose which projects I take on. The funny thing is that since I am not desperate to get any contract, I end up earning more and enjoying the work and the people I work for.

Living in high-cost of living areas, like the Bay Area, keeps you running on that money treadmill. You might want to consider moving to a city with lower cost of living.

Screen resolution of 2880x1620 is a little lower than the MBP Retina 2880x1800, but it's close.

Hmm, so a game developer is like a startup factory?
