Memory leaks are not only possible but they are officially supported. The most obvious being `std::mem::forget` and `Box::leak`. Of course the user of these functions should usually ensure that drop is eventually called for all initialized data but there's no way to enforce this.

If you mean unintentional leaks then that is a harder problem. Others have noted ARC and RC leaks but also thread locals may (or may not) leak[0].

Assuming you are, like the article, referring to the USA, the only schooling that may necessitate a massive loan is post-secondary (as in after primary and secondary) schooling. The government has done a great job of controlling costs of schooling up to that point. It is confusing to me why you call that optional tertiary level of schooling a basic item? According to the OCED, only 48% of American adults have post-secondary attainment. The other 52%, a majority, seem to be managing without, living long and fulfilling lives.

It is understandable why you call housing a basic item. The small percentage without are often left to parish if the lack of shelter isn't quickly corrected. That is a real problem. But is any meaningful portion of the population actually taking out massive loans to make rent? In my experience, a massive loan is difficult to get even when you have a security to back it with. I am surprised that someone struggling to pay the rent each month has any collateral to put up against the loan.

That patent could easily be defeated by showing the older Tesla designs as proof of "prior art". This could happen i) easily after the application is published through an internal submission to the examiner, ii) fairly easily after grant through an "Inter Partes Review"[0], and iii) then still at any time in the future through litigation in the courts.

These submissions could be made by Tesla, or any third party who cares about the illegitimate patent not being in effect. If anyone, at any time, demonstrates that prior art existed before the date of the patent application, that patent can be permanently invalidated. This happens frequently, and is often used by victims of patent trolls to defend themselves. With the side benefit of "punishing" the patent troll.

The colour-blindness explanation is a bit of a red herring in places outwith Japan.

One can be totally red-green colour blind and still have no problem with traffic lights in the U.K., for example. The stop lights are the ones at the top and the go lights are the ones at the bottom. Colour blindness, after all, does not prevent one from detecting which light is lit.

In countries where there might be both horizontal and vertical arrangements, this would not apply. But the U.K. only permits a single, vertical, layout for traffic lights with stop lights above go ones.
Yeah but the U.K. student loans are written off when you retire if you haven’t paid them back already. Lambda writes it off after five years of you haven’t paid them their $30K.

Sometimes I wonder where Mathematica would be if it were open sourced lets say in 2010. It had such a head start over Python.

Interestingly, Mathematica interop with Python is basically non-existent today, even worse than it was in the past. Short term moat building destroying long term viability.

It's pretty hard to do well. If you look at Graal, a lot of the cutting edge research work they've done is about how to do cross-language inlining and subsequent optimisations better. It's more of a function of the JIT compiler design than language or bytecode specs though.
Yes, the UK system is much closer to a good idea than that in the US (which is a complete train wreck). Australia’s model is relatively solid too.

There are, however, some major differences in how the UK structures student loans vs Lambda School:

1. If you attend Lambda School you don’t begin making payments until you’re making $50k+/yr in the field you study. In the UK it’s $24k (at current exchange rate) regardless of what you study.

At Lambda you pay a 17% of income for 2 yrs, capped at a maximum of $30k, so if you get a job for $50k you’ll only end up paying $17k. In the UK you pay a full tuition (generally around $50k + however much you borrow for living costs for four years).

In the UK you have a 3-7% interest rate, Lambda has no interest.

In the UK if you make payments for 30 years and still haven’t paid it off it’s forgiven. At Lambda that happens at year 5.

And perhaps this is the most important: In the UK if you default the University was paid a long time ago. The university gets paid day one and doesn’t have to care. At Lambda if you don’t get a job Lambda School never gets paid, so the incentives of the school are aligned with the incentives of the student, instead of the taxpayer writing a check to cover it.
It would have been quite a lot more expensive, I assume? Roughly speaking, with 2MHz RAM, and assuming a setup where the CPU and the display system alternate (so 1,000,000 bytes/second bandwidth for each), you have a budget of 40 bytes for the visible part of the line, and large buffers are expensive, so it's just a question of how you spend it. Take the C64 as an example: you've got 320 px mono (40 bytes/line), 160 px 2bpp (40 bytes/line), or 2 40-byte character modes (40 bytes/line). I assume the fetches for the 8 sprites fit in the 24 bytes that are left, as each is 3 bytes wide.

Later machines had more bandwidth and more complicated memory systems, but the limitations are still the same. You have a fixed number of bytes you can fetch from RAM per second, the TV scans out at a certain rate, and that's going to limit what you can do.

I think it's better that the founders have a sizable equity but at the same time it's probably a lot harder to grow a company without other investors. But I don't think it would matter in its actual day-to-day business. Dishing out profits as bonuses instead of equity is just a personal preference to them.

Maybe they won't get as dedicated personnel but at the same time if they have kept the company owned by themselves to this point I guess it's a valid choice in continuing doing so.

Is it greedy or not, well to me it shows that the founders are shrewd for sure but.. Are they doing this for the benefit of the company or just to maximize their own profits? Hard to tell. I feel giving up equity isn't such a big deal and it would make me more satisfied having my best employees part of the company. Paying only bonuses sounds a bit cheapskate.

Their debt might have been okay in 2001, but don't forget how reckless they have been with spending (photos of sport related infrastructure the 2004 Olympics is a nice reminder), and they put off reforms for decades.

Infrastructure projects are a must have for a globally competitive economy, profit generating or not. Upkeep is an issue of course, but for some reason Greece wanted to not go back to sheep herding.
One of Bloomberg’s sources told them Chinese spy chip story “didn’t make sense”
It doesn't bankrupt us, but it does cost money. Not really the childbirth itself... that is a one time cost, and it varies greatly with 15K being the high end. But food, housing, education, clothing, and everything else you provide kids, not the least of which is health care.... it all adds up. To about a quarter of a million over time, if you believe the analysts.

So with 3 kids, I'm likely $750K down on my wealth. As a tech worker, that is not bankrupt. But if I were living closer to poverty? Then the problem is less about my personal wealth and more about where I choose to cut corners when raising the kids.
Of course I understand this is the standard justification.

In the US for example, the land we have here was taken by brute force / genocide, then a government was set up a couple hundred years ago (all of the founders have died and only about 5% of the population participated in the revolutionary war).

There aren’t any other real options of where to move where you won’t encounter such a violent entity claiming that if you set foot on “its land” you are giving consent.

You can’t give consent if there are no other real options or if you are being coerced.

What is a better argument is to say that this is where our species is from an evolutionary perspective and that the risk of violent attack by the state if you don’t comply outweigh the benefits. Also, the state provides some things you like (sort of like an alcoholic step father who abuses you but also occasionally buys GMO food and does a decent job of starting fights with the neighbors if they try to come into the house).

There is no morality involved, it’s simply a cost / benefit analysis.

Do you like spending half your tax dollars on military operations? Including buying bullets that go to kill innocent kids in regions that have resources deemed valueable to US capital?

The laws in the United States are not written in such a way that says “if you opt out of using roads or calling 9/11, you don’t pay taxes.”

It’s quite the opposite. You are threatend with violence to pay for those things and much more no matter your use pattern and quite often if you are poor your roads don’t get fixed and 9/11 doesn’t result in cops showing up let alone justice being served.

And simply because other outfits have set up similar rackets worldwide doesn’t make staying in the one you were born into a consentual agreement.
They don't need to press, they just need to ask someone on staff who has a basic knowledge of display technologies. Not doing even a tiny amount of fact checking is a bad look.
The thing missing from this analysis is that on data bus lines like SPI, I2c and others there are "passive" components like resistors and capacitors used for signal conditioning and line bias. If one of these components were replaced with a highly integrated IC, it would be possible to mimic the function of the passive component most of the time, but sometimes hijack existing data streams as a MITM.

This can be used to insert alternative boot code, firmware, microcode, or even FPGA structures.

Note that the component would not have to generate its own signal source, because by merely inserting a lower than normal resistance or capacitance it could alter an existing bitstream to reflect the desired payload.

It would require a high degree of integration and power management finesse, but is certainly doable to replace an existing SMT resistor or Capacitor with such a device.

Ah, excellent, George Stathakopoulos has nominated themselves as the scapegoat. I will be disappointed if they are not dismissed if Bloomberg's allegations are substantiated. Ditto to Steve Schmidt [0] with their post.

Edit: Apparently this is "callous". To be clear, Apple and AWS have both lied about operational issues to customers before and have had human-rights and labor-rights issues in their supply chains for years, China is a human-rights abuser who cannot stop disappearing and brainwashing religious minorities, the GOs of the USA and UK are currently administered by incompetent fascists who have lied repeatedly about this sort of thing for decades, and China has attacked USA companies before [1].

I personally haven't made up my mind; all of Bloomberg's evidence is circumstantial and unverified, and all of the evidence against the incident is hearsay from known liars. But I'm saying that if the evidence manifests, and the story has sufficient truth to show any part of these statements to be false, then I would like to see these folks take one for the team; after all, they stand to gain in stature if the story falls apart! And the stakes are obviously high.

We have constantly accumulating evidence that EM radiation in fact IS harmful. The biggest reason the public is not aware of this, is simply because the wireless industry is making too much money from this technology.

I read a passage related to this, in a book called 5000 years of trade. Countries can be categorized as rich/scarce in capital, land or labour. Those countries that are rich in say capital, tend to enforce protections on capital while relaxing the policies for land and labour. So coming back to this article, I would say that US being rich in capital has strictly enforced and nurtured conditions on its society by which capital has decent return through investment into student, house debt etc., while meaningly deteriorating the conditions for labour (wages). This is the reason why it is incredibly difficult to become rich nowadays in US through wages alone..

> You could just rip the film out of an old LCD screen and rotate it 90 degrees.

At first, I also thought this was just a linearly polarized filter rotated orthogonal to the polarized emission of (typical) LCD panels, which would be far from new. However, that doesn't explain how the film would block an LED billboard which are unpolarized. The article isn't clear if their talking about LED billboards or LED backlit panels, the latter are still essentially LCD panels and thus must be polarized. If the latter, then I agree with you this is as far from revolutionary as you can get.

The article does say that the film selectively filters out wavelengths of light, rather than selective polarization. So, what I assume the film is actually doing is playing off the fact that display manufactuers strive for saturated color emission from the RGB subpixels. The film is a "notch filter" with three stopping bands (in the red, green, and blue) portions of the visible spectrum.

Pixels don't emit single wavelengths (e.g. 555 nm for green). If they did, that would imply pure saturation. Lasers are virtually purely saturated, but even then they generally a band (ableit extremely narrow) of wavelengths. Display pixels, even highly saturated emit in a band.

However, LCD's and the typical high quality inorganic LED's used in billboards emit relatively saturated ligh (e.g. ~30-50nm wide bands), and are able to do so largely with the help of dye-based absorbing band-pass filters (basically the opposite of notch filters) that only allow a few wanelengths to pass through while others are absorbed and radiated as heat.

OLEDs on the other hand emit specific wavelengths of light and therefore do not need/use color filters. However, OLEDs also have inherently wide emission spectra (perhaps ~100nm) due to the fact that it is difficult to finely tune the exciton (excited particles that emit light in OLEDs) energy levels to produce highly saturated emission. Interestingly, Quantim Dot LEDs that function similar to OLEDs, are more saturated that OLEDs because it's easier to control the size of quantum dots which directly relates to emitted wavelength, alas, these LEDs are typically only used in LCD backlights (I'm not sure why).

The point of all this is that you could easily design an optical film with 3 R, G, and B notches of ~50nm or so, which would block almost all light from any display with saturated pixel emission. However, less saturated OLED light would still bleed through. You can't really widen the notch filter bands too much because then you start blocking every band in the visible spactrum, meaning less ambient light can pass through, until ultimately you can't see through the film at all.

Anyhoo, that's why I suspect this is notch filter film vice polarized filter.
Interesting thought. He would have said no I guess. But maybe the apt question is to ask if he’d hand it to a total stranger running by.

I didn't describe them! I just told you what the state of play is.

A lens is a "functional reference". Say you have a data structure of some kind. You can create a lens which points at one of the fields. It lets you get and set that field. Because this is functional programming, when you set the field, you get given a new reference to the whole structure (can't change things in place). So, naturally the way lenses are used involves combinining a reference to a structure of type A, a lens which refers to a field within type A, and, if you are setting the field (not getting it) then you supply the new value as well.

The jury is still out on whether writing programs in this style is wise, but the notion of a lens is fixed now.
