DEFCON and StackOverflow: What Our Traffic Says About Cybersecurity Technologies
Show HN: HeroCore – Smaller, Sexier Arduino Mega Replacement
A friend of mine has spent the better part of two years working on making a smaller, sexier Arduino MEGA-compatible chip named HeroCore. He recently launched a kickstarter and needs help getting it funded. He’s managed to take the Arduino MEGA and made it smaller and easier to work with for the same price as a standard MEGA.

My friend invested his time and energy into this project because he fundamentally believes that beauty inspires beauty. For too long, he’s felt that us makers and tinkerers have had to work with ugly tools. He believes that if we have beautiful tools, we will naturally create beautiful products. And ultimately, that means we will live in a more beautiful world.

Here’s the kickstarter link: https://www.kickstarter.com/projects/flaviodabrescia/herocore-the-microcontroller-that-will-make-you-a-cool-hero

Formula to design freeform singlet free of spherical aberration and astigmatism
Yeah this is borderline insanity to me. I just don’t get the point. I feel like the use case for this is extremely limited.. most developers don’t have such onerous bundle size requirements that they can’t afford to include lodash.
You would be right - the purpose is disallow platforms from blocking racist, sexist, homophobic, etc content. That is its specific purpose.

We know that it is specifically targeted because it does nothing to address truly biased sources like Fox News.

On the plus side it is so plainly unconstitutional that it will be instantly blocked literally anywhere it is challenged - there's even direct precedence in the Supreme Court, there was an "fairness" rule for news shows that was overturned to allow thinks like Fox News to exist. That one wasn't even horrifically biased and only applied to shows that explicitly stated that they were news and current events.
My response to that question is going to be pretty bad:
maybe. corps have interests in building tools that help them with their businesses. individuals, i think, have interest in building cool shit. there was an article a while ago exploring the difference between the 'spirit' of oss in the 90s/00s compared to now, but that's hard to qualify.

when i think of individual oss projects, my brain automatically goes to the old enlightenment window manager, and e12/e13 in particular. it was cool and not very useful compared to fvwm or afterstep, but i think the libraries rasterman worked on in the process wound up being useful elsewhere.

but it's been a long time and i'm recovering from a migraine, so you know.. don't quote me.
Dan Ariely (the "Predictably Irrational" author) also wrote "The Honest Truth about Dishonesty". There were studies there that showed cheating is a slippery slope. Once you cheat with something small, you're more likely to cheat again about something bigger.

To compare, a real small part from "man git checkout":

"git checkout --detach [<branch>]

git checkout [--detach] <commit>

Prepare to work on top of <commit>, by detaching HEAD at it (see "DETACHED HEAD" section), and updating the index and the files in the working tree. Local modifications to the files in the working tree are kept, so that the resulting working tree will be the state recorded in the commit plus the local modifications.

When the <commit> argument is a branch name, the --detach option can be used to detach HEAD at the tip of the branch (git checkout <branch> would check out that branch without detaching HEAD).

Omitting <branch> detaches HEAD at the tip of the current branch.

git checkout [<tree-ish>] [--] <pathspec>…

Overwrite paths in the working tree by replacing with the contents in the index or in the <tree-ish> (most often a commit). When a <tree-ish> is given, the paths that match the <pathspec> are updated both in the index and in the working tree.

The index may contain unmerged entries because of a previous failed merge. By default, if you try to check out such an entry from the index, the checkout operation will fail and nothing will be checked out. Using -f will ignore these unmerged entries. The contents from a specific side of the merge can be checked out of the index by using --ours or --theirs. With -m, changes made to the working tree file can be discarded to re-create the original conflicted merge result."

Well yes of course.
I am introverted enough that I despise going to a barber to get my beard trimmed (and it shows), and would gladly let a robot do it, if it did a good job. There is certainly a market for this.

That being said, when the first thing in the video was the robot jamming the clippers hard into the mannequin's jaw, I realized that while the idea is interesting, it not is not quite ready for prime time.

Scoundrels are scoundrels. Politicians will also cheat in office who cheat on their spouses, it's been clearly demonstrated. I'm not even sure why a study was needed to confirm this behavior that's been observed in broad daylight for centuries.
PDFs definitely have problems but this "story" is an ad for a proprietary format called Turtl.

Clciking through to the company's website and their example publications, these are much more difficult to navigate and confusing than PDFs. Users will find it hard to work through a Turtl document in a linear way and hard to figure out where something is inside the document so they can reference it again.

After the time it took to get PDF made into an open standard, I don't think we want to go back to a closed format that's owned by only one company and which requires their cloud service to function.
These are arbitrary metrics, why does energy density matter for anywhere which has the space? Even in Northern latitudes and high density countries you can generate a lot of electricity with a nominal amount of land. All the more if they can be fitted on rooftops. For sunny places near deserts it can absolutely provide a big percentage, even a dominant percentage of power. The main issue is matching demand to supply, production density is a distant concern.

Start with Bootstrap. Build as many sites as you can just using Bootstrap and then study what the classes are actually doing. Then replicate the classes and make changes to them. Bootstrap has enough that if you go through each thing it has, you will have a decent appreciation for the look and how the CSS/HTML/JS fits together to make a site. Then start using jQuery heavily. Find jQuery modules and use them. Play with the options. Then start playing with the code. Those 2 things will be good enough to then move on to something more complicated; which ultimately is just abstracting these basics and attempt to make them easier. But you have to already know what is happening if you don't want to get confused as to why you are using the tool and what your other options are besides this tool.
More interesting in my opinion than stocking the shelves at the supermarket.
Admittedly I was thinking along the lines of gin and other drinks herbal contents. But while Buckfast Abbey is guarded about "the recipe" they say it is essentially the same as it was 120 years ago. It is said to be made from "fortified wine" (which besides alcohol and sugar, is loaded with plant based tannins, some reservatrol, and any number of extra ingredients), a couple of preservatives, vanilla extract... and it has caffeine in it.

It seems like a liability for the traditional branding if they do not make it as they claim "along the same lines and according to the same basic recipe as used in the very early days" They could be just mixing in highly refined caffeine like an "alcho-pop" manufacturer but I'm not so cynical to expect that.
The title is misleading. The full title is:

> Researchers at Rice University developed a method to convert heat into light that could boost solar efficiency from 22% to 80%

The conditional tense signals that the researchers didn't actually do so, but that the study might enable it. The article re-iterates that this is speculation:

> The implications of their discovery are significant. Research from Chloe Doiron, a Rice graduate student, revealed that 20% of industrial energy consumption is wasted through heat. It could also mean an increase in the efficiency of solar cells, which are currently only 22% efficient at their peak. Recycling the thermal energy from solar cells using carbon nanotube technology could increase the efficiency to 80% according to the researchers. ...

> The 2003 Northeast US/Canada blackout was caused by a race condition: https://odetocode.com/blogs/scott/archive/2004/04/11/blackou....

No, it wasn't. The race condition caused First Energy to not notice that their energy grid was one more line trip away from catastrophic failure. But there were four line trips that day caused by power lines hitting trees and shorting, the last of which triggered the dynamic instability that caused the blackout. First Energy had a whole host of issues that together caused the blackout, and the race condition in the alarm monitoring system was but one of them.

The full report is actually an interesting read. Essentially, the key problem that caused the massive cascade was that the line trips meant that large loads of power had to reroute long distances to get to the Cleveland demand area, and the non-infinitesimal amount of time it takes for the power to establish that route caused several lines to trip, to the point that the demand was cut off from the network before the supply surge reached it.

For solar, it somehow has to integrate with the solar panel, so that the same square meter is used both for direct photovoltaic generation of electricity, and for this IR capture, so energy is obtained from a wider band.

I understand your point that it can't just be driven by a secondary IR emission from a warmed-up solar panel; that's not hot enough to be that useful.

In a more detailed article, there is talk about the carbon nanotube device being useful because it can withstand high temperatures:

They of course understand that they need a big temperature differential.
The world is not black and white. Sometimes something that's awful and terrible in one context is a necessary evil in another.

I think that "physically terrifying (as in, can dead lift a couple hundred pounds like it's nothing) guy who has been convicted of multiple crimes but the police are too afraid/incompetent/paid-off to actually keep him in jail" easily crosses the bar of "I'm not going to feel bad if vigilante justice takes its course".

No one's denying that terrible things have happened in the name of vigilante justice. But this is not the same thing. Justice spoke, but enforcement refused to do its job.
SIM800L costs $2. It supports GSM (AT commands - dialing, SMSs etc.) and GPRS (both PPP and a direct TCP connection to a hostname and port).

Regarding USB dongles, I've been running Huawei E3131 with RPi. I needed to put +5V directly onto the pin header, but maybe now with the USB-C RPi4 the power should be stable out-of-the-box. I have heard rumors that the modem freezes after a while, but I've never ran it for longer than a few days. I'd recommend either investigating whether you can hard-reset the modem with software (cycling the USB power) or even putting a watchdog that will cut power to the entire RPi.

Regarding power consumption, SIM800L is fine in idle, a few mA. However, USB dongles AFAIK do not support power save and they will eat ~100 mA all the time, which might be a significant portion of your power budget.
It would be awesome if the could do it like:

Person A initiates and signs request to delegate for Person B. Person B receives the delegation request and signs it, which produces a positive response. The response (containing Person B's signature= is then 'wrapped' in Person A's request and is only sent on the to destination.
Yeah, and that’s part of why it was so controversial. On top of that, op seemed to be suggesting making it illegal - as in go to jail - not having a penalty, which is substantially different.

>machine learning skips the explaining part and goes straight to making predictions

what? Then we should call it machine oracle. It uses magic to make the right predictions without any understanding. It's like seeing a strong AI beating the turing test and saying: it was just lucky. I can think only of two possible ways to make right predictions without understanding: luck and cheating. Sure, sometimes ML cheats.

This is an example of where desktop and server engineers could benefit from having embedded design experience.

It's certainly possible to create a small, protected area of memory that contains a kernel-level interrupt handler (which itself allocates no memory) whose sole job is to run a couple of times a second and check for thrashing and OOM. If it sees memory problems, it takes over the computer, determines which processes are using the most memory and kills the ones that are expendable. ("Expendable" is a list configurable by the user and yeah, Chrome would be right at the top for a desktop system.)

Embedded systems designers routinely build such watchdogs into their systems. It could probably be added to Linux as a kernel patch.
The three limitations mentioned in the article are:

- Too much scrolling

- Creating a high-quality PDF requires the skill of a designer

- Lack of performance data

PDFs definitely have problems but this "story" (besides being an ad) fails even to convincingly cover them.
If I'm understanding your comment right, you could use Calibre to do this just as easily, possibly with more information. There's no requirement to actually have a file associated with a record in Calibre, so you can add your comments into the metadata (or have the record point to a file with comments and notes instead of/alongside the ebook). I use a Calibre database to keep track of my bookshelves; the metadata includes ISBN, my review, my rating, average online rating from various sites, where I got the book, similar and associated books, etc. It should be relatively simple to get a single-click plugin going that brings up a search for the ($ISBN|$ASIN|$TITLE+$AUTHOR) of the currently selected record. The only thing missing here is public access (the buying gifts part)

I would say falling revenue would be the biggest driver here, in 2010 AMD had annual revenue of 6.49 Billion USD, by 2013 this number had fallen to 5.29 Billion. It continued to slide to a low of 3.99 Billion in 2015.

Frosted Glass/Panel Effect, Cross Browser Solution, Vanilla JavaScript and CSS
Seems to be a bit of a non-issue. They're marketing their material to a younger audience so it is why Snapchat, Instagram, etc. get mentions because that is what the audience is into. What would probably make it a more interesting case is if the rappers mentioning Cash App are backers of it (or receive some kind of incentive from the company) I guess.

Jay-Z (and I would imagine others) has been doing this kind of thing for years: giving a hat tip to whatever ventures they're somehow involved in so that the rap advertises (advertisements that people actually go for) some other revenue stream for them.

Smart moves, really.

Art is a service. I’m more curious about what people would do to get any of the things that are currently “the economy” when all needs are oversupplied by, say, a mere 5% of the population in full time work. Would people work less for the same goods? Would there be high unemployment? How do things shift and rebalance? UBI sounds good, but is it politically feasible — some people get called “benefit scroungers” while others are called “pensioners” and “the royal family”?
They can then break out from the browser, but only get to docker with that exploit, and it's unlikely they have a docker exploit too at hand, is it?

If you are running Firefox on X11 (which most Linux users probably still do), you do not need to escape Docker. You can make screenshot, capture keystrokes, and send keystrokes, all through the X11 socket.

(Furthermore, you do not need a Docker exploit, a Linux kernel exploit can be enough to break out of a container. This is one of the reasons for e.g. gVisor to implement syscalls in userland and in a safer language.)

Using VMs as e.g. Qubes OS does is probably a bit safer than a Docker container.
