Well I also don't think that's as simple as you are trying to make it.

What you wrote is true sometimes. But it is not the rule. Social mix is broad topic in urbanism. There are many developments with some social housing included. And market housing there is not inhabited by poor people just because some poor live in the neighborhood.
Don't forget the 31.42% payroll tax that's hidden from your salary but a tax right on it.

A salary of 50k SEK costs the employer 65.7k SEK on their books, which is what actually matters. The actual marginal taxrate flowing from your employers books at that level is somewhere up at 75%-80%, not even counting sales tax when you use the money.
This tickled me! Thank you.

If the kid throws massive temper tamtrum when I want it to put off the book/puzzle and go eat dinner with family, absolutely yes. If the kid refuses to engage with others, mistreats siblings or other relatives when the activity ends, yes.

If the kid reads/solves and then behaves normally, then it is different.
So you mean it works if you assume that all the heavy stuff you "already have" somehow. Ok, not exactly convinced..

I think I'm the opposite, I prefer smaller shops because I find the big supermarkets extremely tiring. I think it's because of how hard your brain needs to work in them, you need to be making "do I need this?" snap decisions very quickly as you roll through the aisles.

Our neighborhood supermarkets are the size of, say, a basketball court, so they're not as tiring.

Ecom pros, do you do product/competitor research?
To any ecommerce professionals / data analysts here, could you help me out with some ideas for product validation?

Can I ask:

Do you currently do (or would like to do if able) some kind of bulk or automated product research / competitor analysis / ML involving search engine data, ecommerce marketplaces or direct competitor website scraping that provides measurable practical value?

What do you find the most useful about these activities and what kind of questions are you specifically trying to answer?

What kind of data or insights would be practically valuable to you if you could discover anything you wanted to know about your niche, search engine "keyword landscape" (organic, paid (Google PLA's) or other SERP features), specific competitors or their products, marketing assets etc, anything at all related to your entire online market.

What are the biggest market research & analysis related problems you struggle with right now either due to existing solutions being none, inadequate, too slow/complex or too expensive.

Finally can you recommend any related tools in this area you use currently that you consider invaluable must-haves and why? Hoping to find something interesting here I'm not already aware of :-)

Thanks in advance!
Society is about efficiency. Social interactions are voluntarily and can be organised around any random activity such as games, sports, hobbies etc. It's really inflexible and incredibly limiting to force inefficiency of transport, because that increases social interactions.

People had the same argument when banks went online, all the retired people want to still go and pay their bills at the bank, because they get to go outside, meet people etc.

It also very much depends on the geography of the area, some cities simply sit on steep hill slopes and bikes are just not an option unless you're young and super-athletic. Most of "bike-cities" are in completely flat areas and it's not a coincidence.

There is if you intend to use libraries as those libraries may well have chosen a build system other than the one you have chosen meaning you'd have to rewrite their build scripts. This is far from the experience of using libraries in languages with unified build systems which is typically as simple as adding a line with the version of the library you want to a manifest file.

It's important to note that this is from (2019).
e.g. https://www.publichealthontario.ca/-/media/documents/ncov/co...

"All of the COVID-19 vaccines approved for use in Canada are effective at preventing symptomatic SARS-CoV infection and COVID-19 related hospitalizations and death."

Because the phrase vaccine efficacy just means how good is a vaccine at something it can be defined relative to any endpoint you want. Nonetheless, both the way the term "vaccine" has been used historically and the way "vaccine efficacy" was being used as recently as this spring were in terms of, it will prevent you from getting infected and sick.

The original claim was that "vaccine efficacy is NOT against transmission" and that this is merely updated information, not an attempt to rewrite history. But it certainly looks that way to a lot of us because to truly accept that the previously distributed information was wrong would imply a major screwup and thus some sort of investigation and accountability. At minimum it means trial failure, for one thing. The pharma companies claimed the trials showed they could prevent COVID-19. They were wrong. That implies other claims made by the trials could be wrong, which implies the government should suspend the rollout until the true facts about what the vaccines actually do can be established.

Obviously no such logic is appearing anywhere in public health. Instead the message has simply shifted to be, vaccines prevent "severe illness and death" and that's why they're awesome and always were. The Pfizer trial at least, didn't actually show that however.
Also, if you look at the maps with the distribution of the sources of the timber it has areas of concentration that map quite closely to the southern remnants of the Hanseatic League (die Hansa in German) cities / trading stations. And some of the wood used has a time frame that sits right in the middle of the peak of the Hanseatic League power (1370-1438). The Dutch-Hanseatic War of 1438-1441 lead to the end of the Hanseatic League's de facto monopolisation of Baltic trade.
thanks for your time to comment. this looks great. anything particular that might break down or any issues you had?
Well, the USA is only ~250 years old and most of its planning was done in the past ~150 years, whereas most European cities date back to the middle ages or even before that, growing much more organically, often around a castle, wall, church, or all of the above. It's only in the past 100 years or so that cars are a thing.

But the other is just different approach to planning. I live in a relatively new, so-called "vinex" suburb [1], a neighbourhood built according to certain specifications - relatively small gardens, bike- and pedestrian safe, the only cars you see are the ones heading to- and from their house, the rest is redirected to a ring road. And, very low uniformity in housing designs; common themes, but a lot of diversity.

That said, at the moment we have a massive housing crisis - we need 100K houses in the next decade, probably more - and I feel like the only way to solve it is to build boring houses, big apartment complexes, that kinda thing. The alternative is population reduction, but nobody wants that.

That's when you move from NTP to PTP, which in a LAN provides sub microsecond accuracy.

https://en.m.wikipedia.org/wiki/Precision_Time_Protocol

With that underneath you need just one gps clock reciever for the whole LAN, and PTP capable Ethernet adapter and switches throughout, of course. Which most are, these days.
I'm of two minds when it comes to reports like this.

On the one hand, of course I love that people have the means to audit assumptions.

Both the ability to do so w.r.t the project being transparent and open, but also through time and technical ability.

I am, however, a little upset when people poke at minor issues (that they themselves see as minor) and speak at length about them. *not* because those issues should not be addressed, but because it gives ammunition for people who recommend closed platforms, or more opportunity for people to think of the community as being more divided than it really is.

The more uncertainty a thing is surrounded by: the more people are likely to just say "fuck it" and choose any option as long as it works, and guess what works? Closed platforms, especially those with coherent messaging like facebook or whatsapp.

So, with that in mind: Kudos for such an analysis, but be mindful that such a lengthy document that discusses minor issues can actually harm the matrix project.
And meanwhile people keep on ignoring Tox when not sh*ting on it.

I'm not so sure. According to [1], for 1MB data transfer over TLS there's up to 15% overhead used for encryption on WLANs. That's 15% more data you have to process, which is not quite the carbon footprint of your coffee drink if you consider how many requests you serve. And that's just data, not to mention all calculations necessary to actually encrypt stuff.

I do think there is an ambition to be pedestrian- and bicycle-friendly, but at the same time it seems very appealing to build sprawling American-style suburbs with big-metal-box-style commercial districts that are only accessible by car.

In smaller cities, you often have the same people setting lofty ambitions to become the bicycle capital of united federation of planets while at the same time greenlighting yet another massive mall at the edge of town because "oh my god $BIG_CHAIN_STORE wants to come here, we're gonna be like a big city now!", usually at the expense of the stores that are accessible by foot or by bicycle.

Yeah, I'm a non-profit boy. Similar sort of setup. I'm never going to get crazy money, but the work's super interesting and I'm treated like a wizard.

Plenty of downsides. You're often project-funded and subject to the various whims of donor-funded project cycles; and without the sharp discipline of the profit motive, lots of organizations end up being a bit of a bloated, navel-gazing mess.

That said, having done this for many orgs for fifteen years or so, I can count the number of colleagues I've actively disliked on the fingers of one hand; have gotten a tonne of exposure to some really interesting places, people and ideas; and have found the sector as a whole incredibly supportive, friendly and fun.
Nexus Lifecycle / Nexus Auditor tends to be useful for this - in absence of a package.json it crawls the raw js files and finds their source. It can help figure out things like embedded jqueries etc. That being said, it has the same limitation as other tools - minification and bundling obfuscates origins and makes it harder to assign identity to the source package.

The only way that I can think of getting around this is to have a hard requirement for a source registry - or asking the premium plugin producers to produce a SBOM like cyclonedx or spdx and evaluate that in lieu.
OTOH I noticed that kids < 10yrs tend to get overexcited or even slightly aggressive after watching TV. They're more likely to quarrel, if you have two or more.
Obviously this might also depend on what they're watching, but if it's a TV show and they get denied watching another episode it does resemble a drug addict not getting their next fix somehow. ;-)

We have some casual acquaintance we visited two or three times. Their then-4yo was constantly on an iPad on YouTube Kids, switching videos every 20 seconds. Just watching him was infuriating. You had rather innocent or mundane videos of e.g. model trains driving around, but before you could start to pay attention to any details or any kind of narrative, he'd switch to a video of kids in a swimming pool full of orbeez, then something Sesame-street-like. And they just let him keep doing that since he'd throw a tantrum if they take away the iPad. They have to let him watch that stuff at the table, otherwise he wouldn't eat. Fast forward to last year, he got into elementary school and was absolutely unable to pay attention to anything. Teachers made him see doctors, he's on medication now, but that was half a year ago so no idea how things are going today.

Now I'm sure someone will pull the "are we sure we got cause and effect right here?" card, but even if that kid had some kind of predisposition, nobody can tell me that just putting up with the kid's tantrums when he was still four (or whatever age he started at, this was just when I first saw this) and taking away the iPad, going outside more would not have significantly improved the outcome here.
As others have pointed out, you can use (big) servo motors for drive. This means that you go from open loop positioning (ie needing homeing switches) to closed loop, where you know where your position is at all times.

Optical tracking might be useful, but it also might not for the reasons I'm about to describe

CNC machines generally get "better" as they get bigger, not because they have stronger motors, but because they are more rigid. The problem with this CNC is not power, its rigidity. It will cut well enough for wood and plastic, assuming that the spindle is fast enough. However it will deflect significantly as the material "pushes back" against the cutting force.

In this machine, they are using belts an pulleys (which are contrary to common opinion not very elastic) The pulley used to keep the belt in tension are on plastic parts, which are elastic. (steel is also elastic, but much stiffer, so at this scale wouldn't flex as much, well not before the bolts bend)

With all this flex, it affects the accuracy during the cut. you might have felt when a drill bit binds up in a hole, and the whole drill is wrenched from your hand. That happens in a CNC when starting a cut, or plunging into a pocket.

Where big machines come in, is that they have huge mass, which allows for large rails/linear bearings, which are much more rigid. The more mass also means that when the end mill comes under load, the work piece gets the push back because its generally less mass than the gantry.

TL;DR:

yes you can use optical methods for homing, but its better to spend the money on more mass for the x/y/z assembly.

Which Go implementation if Raft do people recommend? (I was led to believe that none of the widely adopted implementations were "smooth sailing" by a colleague who has spent a lot of time trying to make use of Raft).
(Aug 2019)

A lot has happened in and around Matrix since. While this looks like an honest and thorough review, as it’s focusing on defaults and UX/expectations, I’m assuming several things to be outdated. Maybe some of the critique brought up here has even resulted in changes in docs, Element and Synapse already.

Haven’t yet read thoroughly enough to say what, will probably follow up here later.

Note that mxisd (the “only other identity server” referenced), from the paper authors, is now deprecated and part of their “Grid Server”. A community-maintained fork lives on as ma1sd. AFAIK this is the one identity server software to consider for self-hosters.

Also for those new to Matrix, “Riot” referenced is now rebranded as “Element Messenger”.
