>What a roundabout way to admit limitation both in knowledge and tools to investigate them.

Why? I view humans (and all biological beings really) as machines, fantastic contraptions of unimaginable complexity that push the materials they are made of to the absoulute limits. Their brains are the pattern-matching subsystem responsible for Command, Control and Communcications. Maybe expressing limitations in terms of circuits is roundabout to you, but it's perfectly natural for me.

>it almost closes the curtain on approaching this natural order (of brain circuitry) with both humility and curiosity

Again, why? is it because "Circuits" somehow imply rigidity or fixity ? that's not true at all, plenty of circuits can change their structure while they're operating. And even fixed circuits can be so complex and of so many signal paths that they seem to have a mind of their own, especially in a dynamic changing enviroment.

I don't know about humility*, but the two grandfathers of neural networks, McCulloch and Pitts, were both very curious about the brain, and they used ideas from logic and cybernetics to study it. The Nobel-prize-winning Hodgkin–Huxley model is another framework that looks at the activity inside a neuron in circuit-theoritic terms such as capacitors and current sources.

* : That said, "All of your views and opinions are the product of a few billion capacitors wired together" seems to me like a pretty humble way to go through life.
I'm a serious music fan. I've heard of Miles Davis, but cannot identify a single one of his songs.

Though I suspect you'd conclude that not knowing Davis' discography automatically makes me not a serious music fan.
> The underlying problem is that multiplication is much harder to perform with hardware than addition, especially with 1980s-era technology. The solution is that the chip uses base-2 logarithms in many places because adding logarithms is equivalent to multiplying the values.

Maybe it would have been obvious to me if I had taken calculus, but this blew my mind.

I don't really want to engage in the shit-slinging that this thread will inevitably turn into/has turned into, but: alt-right, by many accounts, is a response of neo-reactionary thought and neo-reactionary writers were a common part of online silicon-valley-adjacent communities. It's not just tiki torches.

Not even you can control yourself. This is the culture war: people burning their Nikes on Twitter, people posting their RBJ commemorative mugs on Insta, and you falling into the vortex yourself to kvetch about both sides--no doubt someone will show up to say how their _not like those other people_.

Yeah, I got it to two accounts I use with ARIN, as well as another that is confusing me.

That one is not very old, I know I have the entire outbound history for it, and have not used it for ARIN or anything similar.
> You do all that work at the precise point where the last reference was dropped.

True, but rarely meaningful in practice. People don't anticipate spikes at implicit deallocation sites. On the contrary, they typically use RCs to share data without worrying about exact destructure time (i.e. same reason as GC), and thus will be caught off guard in either case. In fact so much so that even experts frequently introduce accidental RC cycles (causing hard-to-debug leaks).

In the cases where you actually want destruction to be deterministic (e.g. large allocations, graceful teardown, kernel resources etc), neither a traditional GC nor RCs are a good solution.

The simplicity and elegance of Rusts RAII scoped ownership model largely goes away with async, due to the unavoidable "Arc-hell".

People who have only used one language way overestimate the importance of having a decade of experience in one language and way overestimate the amount of time it’ll take them to be production-ready productive in a new language.

Syntax is easy and learning a new approach to language design is a great learning experience. You’ll still transfer most of the good parts over but you’ll also learn that maybe some things you’re used to can be made simpler.
My understanding is that full system backups on Windows requires the tool to create VSS snapshots and back up from the snapshot. Any tool that just copies files on the disk won't work.

I use Veeam Agent for this purpose (free, but not open source). It can do full system backups and supports both restoring to the same hardware and new hardware. Restores are done via a bootable WinPE-based image that the tool creates.

One cool thing about it I haven't seen in other backup software is that incremental backups work via a driver that tracks which disk blocks are changed as the system is running. It avoids the need to rescan the disk to detect what has been changed (though it will still do that if the filesystem is modified outside of Windows, eg. if dual booting).

The biggest downside is Veeam's website. It's pretty "enterprisey" and they want you to register to be able to download. I install via the Chocolatey package manager to avoid this. Chocolatey's package source has a direct link to the official installer [0].

There are no ads, nagging, nor upselling in the software itself. I have not seen it making any network connections outside of connecting to my backup target host and the auto-updates server.

I've been looking for open source alternative with a similar feature set, but haven't had too much luck. There's Bacula, but that seems to very much be designed for an enterprise use case.

Ha I had the exact same experience with Wachovia bank in New York City once and basically their argument was on the lines of “The highest value transaction was probably the most important for you so we ordered it by price so that your most important transactions go through first”.

Do I have the horrible hack for you!

It is possible to do pull backups with borg, with some gruesome ssh hackery.

On the backup client side, you need to have a /root/.authorized_keys line like this (edit borg options to suit):

command="BORG_PASSPHRASE=$(cat /root/.borg-passphrase) borg create --rsh 'ssh -o \"ProxyCommand socat - UNIX-CLIENT:/root/.socket/borg-socket\" ' --compression auto,zstd -s -x ssh://borg-backup@localhost/<repo location>::<backup name> <backup dirs>" ssh-ed25519 <keydata> <keyname>

Then, on your borg server, you need an authorized_keys file like this:

command="borg serve --append-only --restrict-to-repo <repo location>",restrict ssh-ed25519 <keydata> <keyname>

Finally, run a small shell script like this from the borg server to trigger a pull backup:

#!/bin/bash
eval $(ssh-agent) > /dev/null
ssh-add -q /home/borg-backup/.ssh/<keyname>
ssh -A -R /root/.socket/borg-socket:localhost:22 -i .ssh/<keyname> root@borg-client
ssh-agent -k

I trigger this using cron every night, but systemd timers will work too.

The first neat thing about this setup is that the client never even sees the private key that it uses to authenticate to the borg server - the key stays on the server & authentication is tunnelled between client & server via ssh-agent. You don't even need to be able to make a tcp connection from the client to the server - so long as the borg server can make an outgoing tcp connection to the client then everything just works. The client connects back to the server via a socat connection through a unix socket created by the outgoing ssh connection that tunnels any tcp connection made through it back to the sshd on the server. (You could probably tunnel the repo passphrase through as well, if you really wanted to.)

The second neat thing is the use of authorized_keys commands which are tied to an ssh keypair means that you're giving the minimal possible access - each ssh connection can only trigger that specific command & no other. You can issue ssh keys on a per-host basis & revoke them individually if necessary.

You have to use socat as a proxy program for the return ssh connection as ssh doesn't know how to connect to a unix socket & this setup requires

config
StreamLocalBindUnlink yes

in the .ssh/config on the client (possibly both client + server?), as otherwise the unix socket doesn't get cleaned up after the connection ends & the whole thing only works once before you have to remove the socket by hand. I'm not sure why this isn't the default for ssh to be honest.

This method is outlined in the ssh-agent section of https://borgbackup.readthedocs.io/en/stable/deployment/pull-... but the docs don't really call it out as a method of getting pull backups working properly. It's a bit convoluted, but it does work!

(If your client can make a direct tcp connection to the server you can skip the whole song + dance with the unix sockets of course.)

I guess the market analogy would be that you want to buy into an index. So if you’re invested in PHP but you see over 20% of jobs say React it might be time to diversify a bit into React.

This leaves out that diversifying one’s tech skills isn’t as easy as diversifying a portfolio though. You could do a React side project, but it won’t be considered as highly as a full time job. I guess that’s the difference between adding a bit to your portfolio vs. going all in.

> Ammonia can also be burned in modified gas turbines, which IMO would be a great way to quickly displace natural gas in peaker plants, to enable higher renewables penetration w/o relying on fossil fuels to take up the slack.

Nukes can operate as peaker plants. The feedback from the control rods is nearly instantaneous. It's just in some markets they must telegraph their moves and get approval, which can take ~4 hours or more.

I bring up nukes because how are we going to make the ammonia? Nitrogen fixing reactions take loads of power. You could get it from nukes until we figure out higher capacity solar collection, but I don't know of anything else that would work well.

I experienced this as a foreign exchange student… and it permanently ruined me. There’s just no way for me to recreate this experience for my kids, but I am glad that our school district is working hard to put locally grown produce on lunch trays, even if I’d rather have the kids walk home for lunch. It just isn’t a practical model for most American families where parents work outside the home and often with long commutes. Am glad more people are working from home - maybe this model will someday be practical.
I agree.

But the externalities of sorting/cleaning/transportation would also need to be measured.

The article sort of mentions this, but overall it is a typically unbalanced "recycling is 100% good" and "More countries need to pass laws to reduce waste and eventually stop sending glass to landfill" without the balance of looking at the total waste of recycling versus using virgin material.

Meanwhile, I think money is often a good proxy for environmental damage (especially as an individual), because the safest bet is to assume externalities are similar even for two very different choices.

> Unfortunately that leads to this: now imagine said MX servers were under whatever political party you oppose.

Hmm, what could I do?

Maybe change my MX records to move from mailgun to postmark or any other mail provider? Or self host?

But that's if we assume the key servers would have to be the same as the MX servers, because of some technological limitations.

Alternatively, it could be done like SSHFP where SSHFP records exist independently from the CNAME records: then the problem disappear, as you as the domain owner can delegate the MX part to one company, while only entrusting yourself with the publication of the public keys.

If you mean "but what about gmail users" - if gmail servers are under whatever political party you oppose, you've got a much bigger problem, and I don't think there can be a technological solution.

People often confuse money cost with environmental cost (at least it makes it easy to know who published the study ahem).

Here in NL the monetary cost for melting glass is about 85% of sourcing new glass. So it's a small win. The envirnmental cost reduction is the raw materials saved.

Beer bottles are almost all reused for a number of times though, greatly improving their environmental impact. Wish they would do the same for wine bottles.

I'm not claiming anything. I just think the Bell System was doing cool work on operating systems and it would have been interesting to see what would have happened if the government hadn't disrupted that. I pass no judgement either. Since as good as that thing might have been, the breakup also gave rise to opportunities for the tech giants we have today to emerge, for better or worse.

None of these agreements are worth the paper they are printed on

The only realistic solution from global warming will not come from government action, or attempting to force nations into economic untenable positions that have the effect of lowering living standards for their populations.

The only realistic solution is via technological innovation where by coal, oil, etc are made obsolete by natural market forces, not artificial tax schemes, fines, or other such agreements.

People that continue down the path that making these fuels more expensive by artificial government actions will continue to be disappointed in the results, as people need to heat their home, move goods, etc and they will always want do to that by the cheapest means, injecting government policies that simply increase prices of those basic needs of society to make alternatives more attractive will never ever be popular with the majority citizens of any nation which is why nations look to water down the language.

This is a PR event with no substance, like most international agreements.

We had problems with circular imports back then in a Flask based backend. Also we wanted configuration based loading. Local dev, testing, prod, on premise. Plus multi-tenancy meant that everything was very-very dynamic and additional layers of configurability were present based on the request. (So basically request scoped service injection was needed. Of course we did not do that, we just passed around a bunch of parameters in a "very Pythonic way".)
