Polycaprolactone is actually unbelievably strong in one particular way: its fracture toughness is astounding because its elongation at break is usually over 1000%, higher even than polyethylenes. No other structural material even comes close, unless you're counting soft rubbers (latex, polyurethane, or SEBS, but not silicones), which reach high deformations through pseudoelasticity rather than plastic flow.

Unfortunately, PCL's tensile strength is kind of lame, tens of megapascals, like typical polyethylenes — but polyethylenes greatly exceed it in chemical resistance, heat resistance, and moldability. And its low tensile modulus gives it a very low speed of sound, which in turn means that in some applications where you'd really love its incredible fracture toughness, the impacts are sharp enough that it will break anyway. So, most of the time, you're better off with metals or stronger engineering plastics for fracture toughness.

However, the poor moldability and low glass transition point of PCL give it a rather unique property among reasonably stiff materials: you can shape the freaking stuff with your hands while molten. And so it is that you can find PCL inexpensively on Amazon under names like ShapeLock, InstaMorph, ThermoMorph, Kemilove, TechTack, Polymorph, and so on.

Just be careful about the service temperature. Like most plastics and metals, PCL loses most of its strength well before it actually melts.

As for textiles, supposing you could spin PCL into fibers (which I'm pretty sure you can, even if nobody has), PCL tights would be pretty much impossible to get runs in, but they would melt if you spilled hot coffee on them. That might be a deal-killer.

Rayon (cellophane) is also biodegradable. Usually this is considered a drawback. Polylactide is probably the most popular biodegradable plastic going around these days, but it isn't really biodegradable, it's aquadegradable. And it's probably too brittle to make a useful garment fiber, even if the hydrolysis problem wasn't a killer.
We definitely would do something like that with address-book whitelisting or other controls! I expect everybody will. Remote content, even via a proxy, can still identify exactly who has opened the email (also when, unless content is cached - but the whole point with content that might change is that you can't cache the resources and still be dynamic)

It's also going to mess pretty badly with offline mode when we get to that, unless we pre-fetch resources when downloading data for offline.
> The only reason I took issue was because of the adjective "general".

Now, that is an interesting and valuable insight for me.

I regularly teach mathematics where I need to insist on formal nitpicks when they change the result of the reasoning, and I'm used to people not understanding formal nitpicks right away, so I'm used to patiently insist and use analogies, different angles, etc. However, I don't teach in english.

When I say a rule is true in general, then that means for me that rule is always true no matter what. If the word "general" in this context is understood differently, then that explains things.
I regret to inform you that my original comment was sarcasm. I'm not a consultant, but would be perfectly willing to do the job as I described. The hardest part would be keeping a straight face while demanding the $20k.

That's true of Huawei and ZTE too, and yet the government thought it was worth saying don't buy their phones, so I'm not sure what your point is.
> There is no way to create a support team that just handles the clueful people

I've wished on occasion that someone would create a certification system, kind of like what we have for software engineers and system administrators, but for end users. Users could get certified in various aspect of operating and self-installing consumer technology, and when a certified user called tech support they could be directed past the tier of support that assumes the caller is an idiot.

If the only license is involved is the patent license, then they could likely provide it for free. However, it's not implausible the manufacturer of the hardware decoder takes some of the fee.
Fedora here, never had any crash. However, my laptops are Intel GPU only which hotplug just fine, and the desktop, when it had an Nvidia card had no need to be hot plugged. Are you sure it is Gnome crashing, and not X server disappearing from under it?

I also have 27" 4k. Under X11, it is not Gnome's job to do framebuffer scaling, it is display server's. Under Wayland it is, because then the Mutter compositor is the display server. So if you want macos-style framebuffer scaling under X11, use xrandr (i.e.: xrandr --display DP-2 --scale 1.15x1.15).

For the above reason, the scaling coming with Gnome 3.28 is for Wayland only - and that means no Nvidia, until they sort out their API issues.
Not really, I think better solution is to get prepaid number specifically for 2fa. Get separate email for it and always use FB in incognito mode or in firefox container. I think you can minimize your exposure to FB and don't have to give up on it. Depends on how much you need it. I use it mainly for chat. So I have messanger lite on my phone and that is about it. I do not really post/like/commment on feed. I share photos with specific people that I think are interested not broadcasting on the wall.
I still get this, such a pain. I thought it would go away. But 3 months later, nope.
Consumer Reports is an awful publication. Their methodologies are often very flawed and very opaque. I also would not trust Yahoo finance for audio reviews.

As an example of CR's egregiously bad testing, they run battery tests by cranking brightness up to 100% on various devices. However if you have half a brain, you'll realize that display technology matters and is different across phones. At the very least, you want to set the different phones to a certain level of "nits" which is a measure of brightness rather than an arbitrary "100%" which can mean wildly different things. It actively penalizes phones with better display technology just because their displays can output brighter light.
What I found especially grating about that banner was the version that said "These friends all shared their number".

At least three of those stood out to me as the kind of person to never do that, so I asked, and they hadn't. Facebook was blatantly lying and trying to influence me by showing the people that I interacted with the most on their website at the time.
The majority of OpenZFS is under CDDL 1.0 or later, so Oracle can relicense it by releasing a new version of CDDL that permits relicensing any ZFS-related code to GPLv2. Wikipedia and the FSF did something similar to relicense Wikipedia from GFDL to CC.

If you are talking about, say an EpiPen, then that is injecting medical grade chemicals that someone manufactured and packaged. "Rolling your own" EpiPen, including manufacturing and purifying the chemicals needed, manufacturing the delivery device, and then shooting yourself with that, would probably result in death. You appear to be totally clueless in the various ways that any of these processes could fail, resulting in your death. And that is most likely true of your understanding of crypto too. Don't roll your own crypto, and please, please, do not roll your own injectable medicine.

I think tensors are an overly crude way to model things. It's like computer science went back to the 60s and replaced all data structures by homogeneous blocks of memory.

Edit: of course a computer works best with blocks of memory; that doesn't mean a human developer should have the same view. As a simple example, think of the output vector of a classifier. Why is it a vector, and not a structure? Or think of the internals of an LSTM network; there is more structure in there than just tensors.
Well, duh - if you can delete, edit, and upload a NEW email clearly you can change the state of your mailbox. That's a new email though, it's not the same email. Books are also not immutable - you can throw away a book and print a different book with the same cover.

So at that level, nothing is immutable if you have full write access to it.

The difference is, who has access to mutate the message? If you mutate it yourself, more power to you. It's your copy. If the SENDER can mutate it right there in your mailbox, that's a different story.
It's not mutable by the sender. If you edit your email history it will change. If you don't edit it then it won't.

It's not proof by itself, but might be if you can convincingly claim that you didn't edit your received email.

A Peek Inside Alphabet’s Investing Universe
I got about six weeks of Mandarin in middle school. Not enough teachers are available to offer it in most high schools. If you wanted to really learn a second language before university, it was either French or Spanish. Like a chump, I chose French, because the teacher was reputed to give out less homework than the Spanish teacher. I've never even been to Quebec or Haiti. Quelle dommage; ce n'est pas trop utile pour moi. Tant pis. I can't even remember all the conjugations and tenses for etre.

You make Mandarin mandatory in the US, and you'll just end up with a bunch of people who wasted their time learning a language they will never use. And maybe some who will try using it at a Chinese-American restaurant only to learn that everyone there speaks Cantonese, or a lesser-used Chinese dialect.
Same with iOS safari. Perhaps there’s some parts of it that don’t work?
In what sense is it a "new" email? It has exactly the same headers and message body (except for whatever you choose to modify, obviously), including dates and sender and everything. It's like copying a file on top of another file and claiming the older one isn't modified, it's just a "new" file that you're copying. I mean, OK, but how is this a meaningful or useful statement? The result is pretty indistinguishable from having modified the bits of the original email in-place from the user's standpoint.

If you mean it can't be mutated by anyone other than the account owner, then that would be worth clarifying I think? But even then, the same is true of, say, my Google Drive. Nobody can modify my files who hasn't received my explicit permission. So are files on Google Drive "immutable" to you?
Pretty much.

The product managers and architects have to show the discipline to prioritize the enhancements needed to complete a major theme or epic.

The reality of “projects” is that they are always interrupted by other high-priority items, and months later everyone asks why it’s late and over budget.

So just embrace the chaos and make continual prioritization your “project” discipline
The fact that they didn't do 5%/10%/25%/50%/100% rollout over a week or two is just pure amateur hour. It's like OTA 101 for this exact reason.

People always say the big 3 are going to catch up with Tesla but if anything this shows they have a heck of a long way to go.
I was looking at the transmission lines one day and was curious about why there are always 4 wires. Basically, 3 lines carry equal voltage phased 120 degrees apart from one another. This kind of power is easily generated from 3 phase power generators at the power plant. The 4th wire is a common return for all three wires. It is normally smaller than any single load wire because, if the power is distributed evenly, no load is carried on it.

The second part of the system, is that, normally, no one customer will use more than one of the three load lines. That is why most houses only have one transformer on the pole out side their house. The power company makes sure they balance connections evenly within a given area. If they do this properly, the common 4th wire has no load on it.

Some buildings do use all three phases, but they would be running large industrial machines that benefit from having that type of power.

I tried to find the Wikipedia article that covered all this, but can't seem to locate it specifically.

> To me, software and algorithms are the same thing

Algorithms exist outside of software.

Algorithms are formulas or functions for solving a problem.

Software is usually the implementation of one or more algorithms on a computer.
AirBNB should probably let hosts have some input into how their room/space appears in searches. The kind of knowledge you just posted would have been accounted for in the old days by business people who decided to when and where to build hotels. Such information probably doesn't exist in maps, though some hotel chains might have such info.
Well that would explain why they were so effective in the Ukaine campaign, right?

Or you're saying Americans are so much more deceived and gullible?

The Kochs and the Soroses pump so much more money into manipulating elections what the Russians did was peanuts. People would hardly be complaining if they had instead been on Team Bernie. But since the candidate who could not possibly lose lost a Sure shot, people want and need a ready made answer, enter twitterbots and FB ads.

Anyway, the agreeing narrative phenomenon is most clearly evident in the Assange issue. When he was exposing America's behavior in Europe and the middle east and it also aligned with left ideology, he was a hero, Swedish accusations be damned. Now that his leaks hurt the left, he's a tool of the Russians, of course.
And that was basically what allowed iOS and Android to flourish. Microsoft already had an established platform with the PocketPC lineage (damn it, Opera Mobile originated on such devices!) and yet they dropped that like hot potato once the media started yakking about iPhones.

You would have thought that Microsoft of all companies understood the value of platforms, having maintained Win32 compatibility for a decade already at that point.

Similarly Nokia bought Trolltech for their Qt UI toolkit, because it would allow software to be developed that could be compiled for both Maemo and Symbian. But before that could be put into effect, the board panicked and brought in Elop (in large part because of American pension funds, apparently).
> The problem is, over the past few years software has been moving way too fast for the standard patent timeframe.

Two thoughts:

- Why does this mean that they should be eliminated entirely? Why not revise the timeframe?

- Isn't this argument applicable to almost all modern patents, whether software, technological, or otherwise?
This page reminds me of the interactive demos you'd find in a science museum. Those demos were very influential in my understanding of how basic phenonena worked, though I think they often raised more questions than they answered. Nice job to the creator for making something that, I think, would really get a kid's curiosity going.
I think the point is that it's immutable to the user. Nobody can go in my mailbox and change the content of emails that are there. You can't unsend an email (except for weird hacks like delaying sending the email in the first place). The use of the term immutable here is not intended to suggest your inbox cannot be modified in any way by yourself.

A good example of how Gmail has futzed with immutability with "dynamic" content before is how they embed Google+. It lets you +1 and comment straight from inside Gmail, which is pretty awesome! But... in the case of a notification for a deleted post or comment, the dynamic overlay Gmail uses will try and obscure the content. You end up having to go to a mobile or IMAP client to see what was actually contained in the email notification of the deleted G+ item.

Ehh, maybe it's for the best. Such an agency is effectively a check on the power of the entire government, so I wouldn't expect it to be effective if the government is pulling the strings. And, its demise further weakens the illusion that our elections are legitimate and safe from hacking. Spur the people into taking the problem seriously.
I highly recommend the Black Mirror episode Metalhead (S04E05), then combine that idea with this if you never want to sleep again.

Yes, anticipation of future attacks is reason to warrant security measures, and that's what I tried to convey.

More specifically, the fact that a trivial attack didn't happen yet is not always an argument against the need to anticipate that attack.

They may not realize, but they really badly reinforce why people leave.

If you try and deactivate, there’s a horrible series of hoops to jump through which just make the service feel so desperate.

If you minimize your usage, you get flooded with desperate emails trying to convince you to login.

If you’ve stepped away out of fear it’s becoming a low-grade attention merchant full of bad practices, these tactics just reinforce the idea that you really really are doing the right thing backing away.
Why not think of your algorithms as software for a machine that doesn't yet exist?
"How would you decide when to use an FPGA and when to create an ASIC? That depends. FPGAs waste a large amount of silicon compared with an ASIC, so the cost floor, which depends in large part of the surface area of silicon required for the chip, is often an order of magnitude higher than you’d want it to be. But fabricating an ASIC isn’t cheap either."

I think the best way to think about this to think about the tcp/ip protocol. It's a standard protocol but it's decentralized still to this day.

Blockchain takes it further and conceptually adds history to the TCP/IP protocol. This has extreme value as it allow data to behave like physical properties.
While the second half of your comment is correct:

>> The electrical outlets in your home have two power-carrying prongs.

>Only one of the prongs carries power. The other is attached to the earth, and is always at zero volts.

Voltages are about potential differentials, so "zero volts" is relatively meaningless without context.

The neutral line is required by the electric code to be connected to earth at the electric panel, but even if it were not, any ungrounded appliances would work correctly.

Both prongs absolutely carry power. Slap an ammeter on the neutral line; it should be identical to that on the hot line. Don't actually do this, but if you were to cut the neutral line with a live circuit, you would see sparks. This is particularly important when working on circuits with a shared neutral (two hot lines on alternate halves of the split phase with a single neutral line); despite the breaker being off for your hot line, you can get shocked when working on junction boxes for the neutral line. Yes this is up-to-code in all states (though a few places either recommend or require ganging the circuit breaker when doing so).

>> and then they will slowly switch places over the next 1/120 of a second so the right wire is at +170 volt

> No. The power prong (the smaller one) will switch from -170 to +170. The other one (the neutral) is always at zero (measured relative to you).

Here you use voltages as a relative measure, which is correct. As a nitpick you do assume that the person is grounded. Walking on carpet in the winter, I can be at a potential of thousands of volts away from that though.

[everything from here after in ars's comment is correct and I have no more nitpicks]

Ah yes, the sweet taste of abusing state institutions to hold back scientific progress. First it was efficient video and audio compression, now it will be life saving treatment. Ain't the world such a better place for MPEG-LA existing... (that being said, if MPEG-LA wasn't around, someone else would have formed just as evil a patent tyrant company to act as the arm of big media). MPEG-LA is just a symptom of broken IP law just as much as patent trolls and the Eastern District of Texas getting parks built by global corps are.

Not necessarily. If there is a hardware vulnerability specified by the Chinese government, the NSA would not want you to use that phone. They'd rather keep China from having the easy option and then compromise your info another way (that presumably makes it more difficult for China to get your info).
"modify it" - looks like a new email to me. It's going to have a different secure digest. You can argue semantics here - but the main difference is:

YOU can modify the messages in your Inbox.

THE SENDER can not. Unless they have write access to your mailbox and can copy things out in a client, edit them, and write them back.
Without the bad diesel tax, a lot of people choose to commute to work by car because they would end up spending roughly the same as with public transport. The marginal cost of using a car for a 10km five days a week, let's say 60EUR/month, would now compete with 0EUR. For people making 1k/month this is money.
Most distribution transformers have a maximum rating of 200kVA. So depending on their voltage you can calculate the max amps by (200kVA / voltage). Minimum amps is a bit harder to calculate but I would make a best guess of 20% of the max 200kVA.

You can read a bit more about the calculations here[0]

Edit: noted that 200kVA is the maximum rating, not default rating.
Hopefully they'll do something similar to what the US did during the analog->digital switch: provide external tuner hardware to people who can or won't upgrade their televisions either free or subsidized.
