> 27 kbps (that's bits), so the cited 80Kb/s in the linked article for Sidewalk-to-IP communication is several orders of magnitude higher and must contain a lot of (unsurprising) overhead.

That’s not several orders of magnitude, that’s only 3×. Both figures are kilobits per second.

I would also mention that the Amazon Sidewalk thing is for a hybrid of Bluetooth Low Energy and 900 MHz, and it’s quite plausible that that 80 Kbps could only be achieved over the close-range Bluetooth and not in the long-range 900 MHz frequency. As an outsider to the industry with no specific knowledge of what actually caps LoRaWAN’s speed, I’m going to wildly guess that this 900 MHz band, in whatever guise, may be more likely to yield 10–20 Kbps speeds in good conditions.
>I'm 100% confused as to how "focus on getting the 'right' answer"

In my opinion, there is a problem here, but it's being expressed wrong. The complaint should be: "focus on getting the right 'answer'", with 'answer' called out, i.e., that writing a number or expression that satisfies the problem setup is the primary goal. But this tends to teach students to take shortcuts when we need to teach fluency in reading and writing mathematical notation, particularly, as I mentioned, basic notation: fractions, parentheses, variables and exponents.

Is this "racist"? Not per se, but it happens within a system where the higher-class students go to schools that have highly qualified teachers and innovative methods (e.g. IB) while the unnecessariat are consigned to schools which have only "proven their worth" through standardized test scores and which teach students to pass the same; what is unfair is that this substandard understanding is mostly taught to the already-disadvantaged.

But the whole site is written like this: the recommendations of the experts have been filtered through seven proxies of PR teams, not all of whom seem to be trying to offer comprehensible and reassuring explanations.
I don't get it. Both Chrome and Firefox come with password manager which can auto-generate strong, unique passwords. Magic links are nice, but they should not be the only option.
But isn't Rust basically getting constexpr from C++? I saw that in some recent release notes: https://lobste.rs/s/lng3c0/announcing_rust_1_50_0

constexpr is basically making more of C++ available at compile time -- e.g. lots of C++11, 14, 17, and 20 are just allowing more of the language at compile time. Including STL, allocators, etc.

Zig simplifies everything by designing in comptime up front, rather than gradually opening it up with ad hoc rules over 10+ years.

My understanding is that Rust is going down the same path as C++. So you're going to have 2 kinds of macros AND comptime-like/constexpr-like compile time execution.

That limitation is not specific to LoRa but to anything transmitting in ISM band e.g. ~868 MHz in EU, ~900 MHz in US.
It limits single transmitters air time to 1% so that one can build radio communication with any modulation, any protocol and limits probability of collision with different devices in range.

I wonder if ISM band will provide dedicated spectrum for LoRa with unlimited airtime.
The significant thing about "script kiddy DDOS" level attacks, is that they significantly raise the effort and expense for the smallest projects. This is exactly where the most important innovations happen:

http://www.paulgraham.com/marginal.html

Finally we moved over to OVH and placed a few really powerful servers in-front of the game server and applied some ipfilter rules to reduce common attacks. That ended up being the cheapest option out of all the options

The cheaper attacks seem to be at the level, where machine learning could be able to counter them. Raising the bar for inexpensive attacks would be a huge boon to the internet and human progress. It wouldn't be that expensive to fund, either.

We used to run a game server for a small community of around 400-500 people and DDos attacks were something we had to face almost every week, whenever someone got upset with the admin team, the go to solution was was to DDos, you get scammed by another player? DDos. Got banned for saying racist things ingame? DDos. You figured out a new way to cheat in game and the admins fixed it? DDos.

I wonder if this sort of thing could be honeypotted? Give perpetrators a way to figure out and target a fake "edge server" of a particular user? (Which only affects about 5% of your user base, let's say.) However, that "edge server" is actually a honeypot that gathers data on the attack, and correlates that to support emails to the admin team, or flame wars in the game's forums.

This is the kind of suckage that holds back the entire network, but which can ultimately be defeated:

I do not use macOS or Windows, so I have no idea if such an application exists for these platforms, but you may want to look into browser extensions or simply write a bash script that parses the URL, remove the tracking, and add it to your clipboard instead.

As far as browser extensions goes, I use CleanURLs[1] on Firefox, and it works as advertised, removing all sorts of crap from URLs before you even need to copy them. It also provides a JSON file with all the rules they use[2], which if you are building a bash script with, you could use to build the parsing logic.

There may be some room to question the general technical expertise and competence of a shop that runs a bunch of Windows 7 systems, though

Or they may simply not have a choice.

My company has a particular automated machine that I have to work with once or twice a month. It is controlled by a computer that runs Windows XP. It can only run Windows XP because the company that made the software went out of business years ago.

Because of that, the control computer is not permitted on the public internet. When I interface with it, it's using a dedicated laptop through a VPN to a remote session which then accesses the control machine on a dialup connection. It's slow as heck, but since I only have to do it once or twice a month, I deal.

Just before the pandemic, we looked into replacing the circa 1995 automated machine with a new one. Because of the nature of the machine, and the local government regulations about replacing it, the cost would have been little over one million dollars. Not going to happen.

Everyone hates it. But that's why my company's IT department, which tries hard to keep up with the times, has a single Windows XP computer in its stable.

I saw a 160lb security guard tackle a 90 lb woman who was probably in her 50s; that was freaky enough. I can't imagine one with resistance.
Quite a few standard password login flows have a "magic link" stream already, in the guise of password recovery -- enter your username on a link, click "forgot password", and get an email with a magic link allowing you to log in (after resetting the password). Which means the security model is not, in some cases, exactly what it appears to be...
All good points, but I don't understand the title.

AWS Australia network connectivity failures
AWS are reporting that they have an issue with an external provider outside of their network, which may be impacting Internet connectivity between some customer networks and the AP-SOUTHEAST-2 Region.

We can confirm that this is indeed having significant impact globally with intermittent connections from regions around the world.

AWS state that "Connectivity to instances and services within the Region is not impacted by the event" which is somewhat amusing in that they're saying so long as you don't need Internet access, everything is fine.

We've had to route all traffic away from the Australian region for edge messaging service, see https://status.ably.io/incidents/718
Pipelines leak because they are pressurized pipes that are filled with oil. The amount they leak annually is comparable to large tanker spills, but since it occurs constantly at a low level in a way that is less visible this type of leak is under reported. This also has a carbon and environmental cost that must be weighed against alternatives.
Hey, congrats on your launch. The first thing that comes to my mind is I hate recording myself. Even on zoom meetings I try to turn the video off as much as possible. It also seems easier to me to share a thought or suggestion over chat when there is no expectation of instant reply given writing something down forces you to filter your thoughts and specify the concrete details. How do you show the utility of self-recording to such people?
From reading the article it seems likes they're using the fact that photons are Poisson distributed. Just like raindrops or particles emitted by radioactive decay, you can determine an average rate of flux and the probability distribution of where particles will hit your detector, but for any given moment, you don't know if a particle will hit at that instant, and you don't know where. With a super fast camera, they're recording many instantaneous snapshots to see if and where a photon has been detected.
> being drip fed a bunch of transactions

Where are you getting ideas like this? How fast do you think internet connections are?

Only in the context of bitcoin do people start thinking 250 byte transactions are somehow difficult to send over gigabit connections. The average bitcoin block is 900 -kilobytes- at most at 10 minutes on average.

How is it that people have absorbed propaganda that makes them actually think that causes anyone a problem? blizzard.com is 13MB, gfycat.com is 29MB. Who are these miners that are struggling to send out 900KB ?
One thing I like about the implementation that magic.link provide which isn't clear from reading the article is that the device you use to log into the passwordless service and the device you use to log into your email can be different. For example, I can log into this incidents.sh service on my work PC and click the one-time link on my phone and it will work. No need to sign into my email account on my work PC.
Without the MCAS the plane would stall. Which would lead to much more accidents than without MCAS or with the broken MCAS as we have now.
Those can be actually worse because you end up having to choose a different password every time, and you're probably not going to make it stronger every time you forget...

>>If you skip verification, you open yourself up to bad actors feeding you a bogus header - and you only figure that out after being drip fed a bunch of transactions that don't match the merkle root.

Malicious actors can't give a bogus header, because you can verify the bogus header doesn't have enough PoW. If the malicious actor does produce sufficient PoW for their bogus header, they are foregoing massive block rewards to fool your node for a few seconds. That's why this kind of malicious activity doesn't happen, and why miners do validation free mining on a new header until they've verified the whole block.

There are problems that are inherently tree-structured and where anything other than recursion feels wrong.

“Process all the files in this directory structure, counting them and summing their size.” Sure, you can solve that without recursing, but I’d trust a recursive algorithm to have fewer hidden bugs.
Interesting history on this one:

39. Sun-and-planet motion. The spur-gear to the right, called the planet-gear, is tied to the center of the other, or sun-gear, by an arm which preserves a constant distance between their centers. This was used as a substitute for the crank in a steam engine by James Watt, after the use of the crank had been patented by another party. Each revolution of the planet-gear, which is rigidly attached to the connecting-rod, gives two to the sun-gear, which is keyed to the fly-wheel shaft.

Good luck detecting a mosquito optically from a distance of several meters using a cheap camera and Raspberry Pi. Oh and you want to do from a moving drone. That will certainly make it work!

Just look at the images in the article - the guy's best result was detecting a black speck appearing on a nearby white wall with some 60-70% reliability (based on his own numbers). So you would be missing a lot of mosquitoes - but will be happy firing the laser at random shadows and what not. And that was in a completely stationary setup and controlled lab conditions, i.e. not at all something resembling a typical poorly lit room!

This article is BS. Preprints are not peer reviewed (i.e. nobody has checked anything in it - so could even be a complete hoax), it is a pretty typical gadgetry style paper (we do it because we can, not because it makes sense) you do at when you need to fill up your resume with research papers (e.g. for keeping/obtaining a job reasons).

The "save the world" (mosquito control, diseases, etc.) justification is also par for the course for this type of crappy paper. Anyone who seriously thinks that one could control mosquito problem by shooting them one by one by a laser is delusional.

But neural networks and "AI" are being used, so it has to be cutting edge groundbreaking stuff, right?

BTW, this nonsense idea has been floated as a publicity stunt a few years ago (including a slow motion video of a laser burning off wing of a mosquito in flight) and it seems that some Russian PhD student from a fairly obscure uni either didn't do their research or has reinvented the wheel (or just plain copied the thing without attribution). The list of irrelevant or only very tangentially relevant (it is about mosquitoes, so in scope, right?) references is a dead giveaway there (paper on mosquitoes spreading zika? seriously?).

In any nonprofit or mentorship situation, I always make sure to reach the children who grew up like me because they truly have no means of assistance.
As I understood the service, it does not require that you click the link on the same machine that you login from. In fact, the screen shots sort of assume that you open the mail on your phone even if you login from your desktop.
