Can VLBI be done with a single moving telescope, with a very precise clock?

I'm thinking of a single frequency point source in space. The received signal will be periodic. Thus we can move the receiver to a new point in space and still know what the received waveform would be at old position based on its periodicity (if we have an accurate clock). From there we can do interferometry?

A Fourier transform allows the same reasoning to be extended to a multi-frequency source. We can also extend the source spatially, in the same way an arbitrary hologram can be considered to be a collection of "zone plates" due to a set of point sources?

If the above is true, can we use a single Earth based telescope (with clock) to form a telescope with a diameter of the Earth's orbit over the course of a year?

Maybe the flaw is that it assumes that the scene being observed is static over the period of observation? How much change can be tolerated before a scene is no longer static?
I use Trello. Its columns show different categories:

- C2: Blog ideas (and helpful resources for them)

- C3: Entertainment list (tv series watch list, my fav movies, weird directors, etc.)

- C4: To learn list (Articles, books, etc by their subjects)

- C5-10: Learned items (important things i learned sorted by subject and finished time)
I think the author is mistaking cause with effect.

When the things mentioned (Sleep, Diet, Exercise, Stress Management, Exogenous Compounds) go out of balance, that "unbalancing" may well be a symptom (consequence) of the mental issue and not the cause as is implied in the article.

You can invest all you want decades in advance in creating balanced habits in those areas and still be disrupted down the line with negative mental health events.
What is the difference, to you? To me, working for improvement can too easily become redirected towards self-aggrandisement. I did this, I accomplished this. Working for justice implies that laws and rights, natural or human-made, are being denied and broken.

Consider perhaps part of the reason kids can adapt to new teachers each year is because there's consistency among the other members of the community, and that swapping the entire community out each year might be detrimental to their experience. Also, not all kids adapt that well to new teachers.
> Signal DOES NOT get your full contact list

The full contact list is uploaded to Signal servers by the phones. The only protection layer that users have is the questionable security of Intel's SGX.

It's still much better than what WhatsApp is doing, just not a black and white situation.

To add a point to your list: Signal does not have automatic cloud backup of messages, unlike WhatsApp. On WhatsApp, 30% of users have cloud backups enabled [1], meaning that you can basically assume that any reasonably sized group's messages can be accessed by people who have subpoena-power over Google (chance that there is no backup-enabled account in a group of n people is (1-0.3)^n... for 6 people it's already 12%).

According to https://www.therobbinscompany.com/projects/the-channel-tunne...:

"In December 1990, the French and British TBMs [tunnel boring machines] met in the middle and completed the Channel Service Tunnel bore. In all of the tunnels the French TBM was dismantled while the U.K. TBM was turned aside and buried"
Yeah, I really don't get how they arrived to that conclusion. The meaning of bella figura is good impression, it really isn't ambiguous at all.

A frustrating thing about inlining in Go is that there's a fairly arbitrary cost model and you sometimes end up fighting it (lookup George Tankersley's talks on YouTube). There have been tons of discussions about whether or not it should be user configurable, if inlining hints should happen at the call sites or function definitions etc.

It's quite a nice discussion that helps people understand the toolchain. It also goes to show that while a self hosted build system is nice, you forgo decades of gcc/llvm optimisations. https://github.com/golang/go/issues/17566
I definitely agree if somebody wants to do stuff like volunteering, that would probably be good for their mental health.

Or we could behave like China and just demolish homes without legal recourse. In 50 years, very, very few people will complain about it.

Even in Kent now, after HS1 has been around for 10 years, you'll be hard pressed to find anyone that complains about it.

It's also added £300m to Kent's economy over the last decade, and the bulk of that has been in the last 5 years as traffic has ramped up.

It is also a matter of culture. For example cutthroat capitalism is not really a thing in Europe, social capitalism (or soziale Marktwirtschaft) is. Culture plays a huge role in this. Most Europeans have a lower risk appetite since it's not like Europe is swimming in successful, well funded, well advertised startups to set an example for a new generation of entrepreneurs. Most also value personal life too much to be willing to make all the sacrifices a startup would require.

But one of the biggest issues in Europe is that it's not very unified yet. A French startup will launch a French product, not a "European" product. The only way to get buy-in from enough people is to have a multinational startup and product. An initiative promoted by both Germany and France has a better chance since it may appeal to ~150 million citizens.
Our germanophones are boring but punctual: their extra meals are Znüni (the 9am) and Zvieri (the 4pm). As far as I'm concerned, it's a oxymoron to eat merienda according to a clock...

> The death toll (CFR) in India is suspiciously lower than in the European states

There are too many other, far more plausible, reasons why the death toll in India looks lower:

* Population pyramid - far fewer people aged 70+ as a percentage of the population means a far lower CFR

* Hotter weather which slows the spread of coronaviruses massively

* More sunlight means less vitamin-D deficiency (which seems to worsen infections)

* Low amount of travel to/from initial seeding spots means closing borders was effective (Wuhan, northern Italy, Alps)

And that is without casting any aspersions about causes of death being attributed correctly.
It isn't if you do it well. Think of WhatsApp that had about 55 people when it was bought for several billions. Especially if you need it done quickly, many mediocre developers are no substitute for a few good developers.

Maybe SAP and Telekon can be arsed to gather their best if it's actually important. For Toll Collect, the usual suspects failed very hard. Much effort, buggy and very late results.

I agree, but "more realistically"? those cases were pretty realistic I think. If you run the script on a box where you have users who can do whatever they want, at least the script should fail on bad inputs.

Genuine question: how would someone define "mental health" or be able to determine if someone is mentally healthy? Even for myself, I really have no clue whether I'm mentally healthy or not.
Yeah you have to manually start an encrypted chat. I always thought that increased the sense of security since you have the lock symbol and all but apparently people prefer encryption by default.
The UK has had sitcoms on the radio since the 50s and TV since the 60s, when there weren't many channels. I think it's more down to what the controllers of the channels want to put on it. Sitcoms can be extremely popular - Only Fools and Horses was watched by around 40% of the UK population at its peak.
But they do have all to do with low salaries. My salary is low for American standards, but I can rely on public hospitals, public schools, and public transportation systems. I do not need to save for retirement either. Or for my kids tuition.
Upvoted. The backlash against HS2 is really annoying, yes it is expensive and some people think it won't benefit the country much - but you covered the reasons why we should be continuing with this project.
I only skim read the article, but I think it's missing a key section which is "strong relationships". Having the right people around you and having a sense of connection with those people can have a dramatically positive effect on your well-being. Aside from that I agree that it's good to invest in your mental health like you would physical. Definately take the time out to learn how to look after your own mental well-being and you will probably see benefits translate to all areas of your life.
Plus, unlike at a photographer's, you can repeat this process in your kitchen 50 times if you want until you get a picture that you're happy with.
"natural languages don't have teleology; they don't become «better» over time, just different"

I remember reading about the dynamic of language evolution, where an influx of new (and language-wise uneducated) speakers tend to botch and thus simplify much of the existing linguistic constructs. Then there is the opposite effect, where once the group of speakers becomes more uniform and educated, people become more willing to adopt/respect language conventions and even go on looking for ways to express more nuanced distinctions and improve the language in general.

And the cop will say "I don't believe you you terrorist" and lock you up until you say something else. This has happened time and time again, including in the latest Hong Kong protests, on American border interrogations and it will happen in these US protests as well.

Thanks, that's exactly what I feared and would call strategical/non-technical ;) I mean it mentions "open source technologies", and contains a vague general description of the concept of identity providers, and, of course, platitudes a la "industry 4.0" but nothing concrete. I want to hear about protocols, operating systems/POSIX/Linux, integration into TelCo provisioning platforms maybe if that's on the radar and they want to have 5G on board, payment standards, containers (chroot, VMs, Docker-like/Linux-only namespace containers, or whatever), or even IP networking. Also, going by the stock photos and the use case example, I'm a bit surprised this is targetting industry applications rather than public authorities, schools, medical etc.
imo it has the best UX of any chat app right now. It's like a souped up WhatsApp. Faster too.
I would love to buy this books, but the price seems way too high. I would pay ~$20 without thinking, but seeing that bundle costs $78 I don't feel comfortable anymore. I start to second guess if I really need this book right now etc.
Can we even distinguish those in practice? AFAICT its main problem was being so general-purpose that it was hard to describe as a compelling use case.

Of course, I also don't subscribe to the belief that the popularity or memetic prowess of an idea defines its "success" except commercially. I thought it was a very nifty thing. To me, that counts as a success. Alas, that is not the metric used by companies. :p
It's harder advice to give. Trying to wake up at the same time every day and not drink coffee before bed is, at least in theory, something anybody could do without too much difficulty. Going out and making more friends, getting more involved in the community, is a scarier idea to propose, especially if somebody already has some kind of social anxiety.
It opens pretty quickly for me, but almost every time it wants to be re-linked to a mobile device.

Signal is really annoying with all the things it wants me to do. Re-linking a mobile device. Re-entering a PIN/password for no reason other than to prove that I still know the password.

And when I'm finally logged in it shows me a completely useless selection of mostly obsolete contacts.
Honestly I don't really understand this. I'm a longtime signal user who installed whatsapp recently (family group I had to join) and.. It feels more or less the same to me. Maybe it's because I haven't allowed any unnecessary permissions, but I don't see much functionality that's different. Statuses maybe?
Please correct the misspelling of TRAC in the examples section. (Or link directly to Wikipedia.)

And I really enjoyed your analysis. But I think Forth (or Joy) deserves a discussion.

I also wonder how homoiconicity relates to lambda calculus. Pure Lisp contains additional facilities that basically allow one to introspect lambda expressions. Somebody must have studied this theoretically.
I wouldn't put much stock in Ayurveda or even worse, Traditional Chinese Medicine, except some of the treatments which have been proven to work. There's a reason why western medicine is superior - it follows evidence-based modern scientific and research principles, not hogwash.
Realistically, compilation speed is something every major language is going to try to improve upon to improve adoption.

I haven't looked at the internals of the go compiler, but it seems a bit simplistic perhaps in the interest of improving speed. For example, it stops outputting errors after a point when it can clearly go further after having demonstrated that it's parser can recover. The error messages have lots of room for improvement, particularly compared to Rust.
> Here it's often seen as a little sarcastic or teasing as there's a tiny culture implication that it means they didn't prepare enough.

I have always thought the same thing about "Good for you" which I think would commonly be translated as "Schön für dich". You cannot possibly say that without sounding sarcastic.

Regarding "Viel Glück", I usually use "Viel Erfolg" when I'm being sincere.

Phone numbers are also guaranteed to be recycled. Every single whatsapp contact I have that's older than 3 years is no longer the original user. I know this because their profile picture is shown to me for some reason. Phone numbers are an outdated system that have no place in modern communication, especially not privacy software.
Skype has always worked for me. Unfortunately it's not secure.

Usually these trade-offs that logically follow different priorities. With a large company, it's important not to break things. With a small company, the speed of iterating and moving things forward can be much more vital from a business POV.

However, if you say you're confident that

it's just crappy quality and not a trade-off, as I would assume in a usual case.
I'm working on pretty much all of the suggestions from the book so I'd highly recommend giving it a read if you can. Some big ones are moving closer to nature, spending more time with a close group of friends (at least pre-lockdown), looking back into my past for things I'd avoided thinking or talking about.

Also meditation was for me a pretty good mood improver, but it's more recently helped me uncover some painful thoughts and surface emotions that I'd essentially avoided without realising it.

Lastly, the value of exploring all these things with a therapist can't be overstated, if you have the privilege to afford it.
I would say your standards are very reasonable and should be implemented across the board.

In my experience it's very easy for company culture, namely in smaller businesses, to get the impression that code quality is a luxury rather than a necessity. And it's even easier to have good intentions, but due to a lack of cultural enforcement just keep them at intentions and never implement anything.

So I would say that you either try to get your standards across or learn to live with lower standards .
> For example, allowing passing around dicts/maps/json (and possibly other data structures) would already be a massive improvement.

Well, it is allowed. You can of course serialize some data into a structured format and pass it over a byte stream in POSIX to this end, and I think this is appropriate in some cases in terms of user convenience. Then you can use tools like xpath or jq to select subfields or mangle.

Your standards seem to make sense. But I suspect there is immense variability between different companies.

You should I believe push for changes with examples of good development practice. Start with easy things that can have impact, and hope the improvement in quality of life due to better practices will stir more interest in improving their process.

But if you have to be the jerk about everything and people just end up resenting you for it, well I think you know what to do.

good luck.
Great write up. One thing I would add is how pipes do buffering / apply backpressure. To my understanding this is the "magic" that makes pipes fast and failsafe(r).
If UX is the concern then Matrix/Riot may not fare very well.

>If I worked for my own happiness, how would I look at myself in the mirror knowing that my happiness is based on an unsustainable lifestyle?

Clearly you have goals/values other than just "maximising own happiness". If your goal was purely that (not suggesting it should be), then those other values would just stand in the way of happiness.
Eeek. Doesn't sound like you're being unreasonable in your expectations at all!

I've been a small business owner, and a software contractor, so I've seen a fair few medium/large python codebase of varying age and quality.

To address your points from the ~10 codebase I've worked on in recent memory:

- Code review: Always in place, though often the CTO has a tendency to merge without review on evenings/weekends

- Test Coverage: Often a challenge - or rather tests are there for coverage, but are of poor quality and don't really assert anything that useful

- Your suggested normal workflow _is_ the normal. Sometimes there's been a dedicated QA team that verifies the changes as seen by the end user too.

- Deployment: Yep. Heroku or k8s have been common, but at least some form of 1-click deploy/promote

Perhaps I've just been super lucky! There are often still major problems in the codebase and refactoring/rebuilding needed to address the challenges, as well as resistance of the existing team to truly change their mindsets to address the problem v.s. the band-aid (or instant gratification) of a quick fix.

Don't give up the fight!
