No blog post, but collected some good photos of our setup, perhaps I should write my second blog post (my first was about the acquisition of my podcasting tech start-up, https://andrewda.com/blog/omny-studio-acquired for those who like stories with photos).

As per the EDIT yes one of my two brothers is a professional chef, I also completed a short course to be accredited as a food safety officer/supervisor (a requirement to run even a short term food business), spoke with Uber Eats about the onboarding process, discussed our brand/food options together, found a location in a pocket we thought would do well for that cuisine etc.

If this is of interest perhaps I can put a few little things together.
"until today we are not pointing towards those who's fault it was."

Is the rest of the world, including the EU, so helpless and agency-less that it can't recover after a 15 year old event that originated on a different continent?

Unfortunately at least in the EU we seem to be (I am your neighbour from CZ). One of the reasons why so much money flows into houses is that they promise better returns than normal stock (shares of corporations). And that is because our corporations have become sclerotic.

Another reason is the artificially low interest of the Eurozone, designed so that Italy and others do not go bankrupt when servicing their own debt. This fuels a mortgage bubble, but it has zilch to do with America.

The Czech central bank raised interest rates (we do not use EUR yet) and the prices of houses stopped climbing very abruptly. They stabilized on a high level, but they don't grow anymore. Given that there are no buyers anymore, the prices will have to go down.
Those celeberities were never queued up 20 deep at my favorite hiking spots to take selfies.

>What if 80% of the public follows the political issues and is well informed? What if 40% have rational reasons to vote for the right-wing, and 40% have rational reasons to vote for the left-wing? Then it is the most ignorant, badly informed 20%, voting somewhat randomly, that will determine every election.

I feel like I see this sort of analysis a lot. You pick whatever set of voters you want to focus on, hold all other voters fixed, and declare your set as "deciding" the election. As if their votes count while others don't. By what possible metric does this supposed 20% "decide" the election, but any other 20% bloc does not?
Ask HN: How much info should founders share with early stage employees?
I'm the founder of a small 7 person startup in the fintech space.

Should I share info on upcoming behind-the-scenes partnerships, etc with employees to pump them up? Or is giving too much information counterproductive/risky if an employee leaves?
>These guys are so unscientific...

Naaaaa, this is not my field, so I assume I'm missing some crucial pieces of information (which the paper apparently lack too, I agree on that).

>A bright yellow meteor trail will saturate red and green, and then blue.

Here I assume that they can do their job, but maybe you are right. Since they are doing their observations at two "meteor stations", maybe they know what they are talking about though.

>Their entire method and conclusion all hinges on analisying the relative intensities of RGB colours of photos of very bright meteor trails.

They use a simple mathematical model, with even other obvious limitations, like considering the atmosphere homogenous, so?

Here I'm citing the calibration part (which is a bit disappointing, true :) at the end of page 4:

...The color chart in Fig. 10 allows us to evaluate the color characteristics of the Moon and check the
calibration of our cameras. The Moon has a color relative to the sky background: B - G = -2.5 log
(1.7 / 2.7) = 0.5. We take into account the color correction in the Jhonson B - V system according to
[x] due to Rayleigh scattering equal to 0.14 magnitude. Let’s get the estimate B - V of the Moon: B
- V = 0.50 + 0.60 - 0.14 = 0.96. The actual color of the Moon is B - V = 0.91 according to [1] and
differs from our estimate by 0.05 magnitudes within the photometric error.
In Figure 9 we can see a local feature (water tower). The color diagram of the tower in Fig. 12
gives a distance estimate of 0 ± 1 km. The actual distance is about 300 meters. Thus, colorimetric measurements confirm our estimates...

They absolutely did.

It was by happenstance that our generations grew up without the same influencer content being pipelined into our brains not by virtue.

> People who are social influences due to something else i.e. sports/entertainment, that's fine,

Why? Why someone's ability which is apropos of nothing worth turning into a following? Sure I can respect an impressive display of a skill but fame in general seems toxic to me. People see one thing a person can do and they wish to know them, emulate them, hear their opinions. I don't see that as that much better than following someone because you like their marketing.
The same happened during the early days of the internet. Insane amounts of companies were founded, hyped and IPOed. Many many naive people turned into investors, losing trillions of Dollars.

Should we have discarded the whole internet idea because of that?

This. Companies should be charged, sure; but an upside of Slack is that I can use various tech community’s Slack, the union’s Slack, and the coworking’s Slack in the same app.

None of them can pay, and they should be sponsored by our usage of Slack for our main job.

I was never stressed out in terms of English language (I'm from Poland) because I've rarely (never) switched game languages to any other language than English.

When I was ~10 years old I've played through whole Final Fantasy 8 which I was obsessed at the time thanks to my older brother with a PAPER dictionary on the desk (I was translating stuff that I didn't understand) and I think that was the most effective way and time when I've learned most of the English language in my life.

Now I'm trying to encourage slowly my kids and I switch game languages they play from time to time.
In Germany (Europe?) it's not allowed to charge additional fees for using a credit/debitcard. However even bank transactions that were externally charged from your account can be reversed for up to 6 weeks.
Paypal can link to your CC and I have never seen a reduced fee for Paypal either.

But why have the middleman if you can a avoid it.
And if your kid isn’t sleeping through the night yet, then just break everything up into smaller units.

Don’t forget to set expectations with work, schedule units into your calendar as reminders and use timers if you need to.

For example: 30 minutes every four hours you work on X. If there’s an interruption no worries just skip and catch the next one

This is really neat feature, I wish all games have such functionality (especially RPGs!)
Yep with the inside-IR35 contracts I need to charge a premium, but even the +20% premium I charged with my current contract is not close to covering my extra costs.

I'm also strongly incentivised to do stuff like timing long inside-I35 contracts (eg 12 months) so they straddle two tax years so that the marginal tax rate in each year only approaches "very unpleasant" and doesn't reach "extremely unpleasant". And with the remaining time either do outside-IR35 contracts if I can find them, or just stop working and enjoy my time and money because at 70%+ marginal tax rates the motivation really starts to dissapear.

I think the best way to understand this is that Gen Z life and prospects are more like The Hunger Games

The ones that choose to do this are volunteering for tribute, go make their face known amongst potential sponsors, and go out into the hopeless world streaming it live hoping for the sponsors to send them gifts and be subscribed financially to the outcome

Its not really as vapid and narcissistic as it otherwise seems

I love chinese and its grammar/expressiveness is fantastic, but having lived in China and now Taiwan, I have a hunch that for even for native speakers Chinese is actually harder to "make out" than English.

For instance all Chinese movies/shows have subtitles that everyone reads along with (even in Beijing/Taipei). At first I thought this was for people that have poor Mandarin (minorities, old people that only speak a local dialect etc) but it seems even people that only speak standard mandarin also "need" subtitles to make out all the words. Without them a lot of words aren't distinct enough to make out over speakers/headphones. In every day speech as I understand it's common to not make out words as well and to kinda guess along what the other person said. It's possible to speak clearly, like a tv announcer, but as soon as you get a bit lazy or speak to fast it's easy to become unintelligible

I'd be curious to hear some native speaker's thoughts on this
For the average use "handle a private key" just means installing an app. If crypto currencies were popular enough, it would already come with a phone, just like a browser.

People already keep super important stuff on their phones. Their email accounts, their lifetimes photos, their contacts, their notes... Losing those seems to be more dangerous than losing your digital wallet. An event that would be similar to losing your physical wallet.
I like that in Discord you can choose to spin off the conversation into a separate thread, or you can reply within the main chat and it quotes the comment you’re replying to (and the quote is clickable) in order to see context. You can’t do the latter in slack, and it’s easy to not realize that others have started a thread when it’s above the fold.

> These both rely on (I think) informal/slang way to contract past-tenses.

It's called "příklonné -s" and yes, it's mostly used in Common Czech (the informal dialect we use in day-to-day life). I wouldn't call Common Czech slang because basically everyone speaks it or some form of it, it's not restricted to members of a subculture, profession, etc.

> would more correctly be used as “smrskl[a] jsi se”

Even native speakers almost never get this right -- “smrskl[a] jsi se” is the formal-ish-sounding form, but it's actually incorrect. "smrskl[a] ses" is the correct (codified) form. And yes, the verb is reflective, although I can think of some reaaally relaxed Common Czech sentences where it wouldn't be. (Smrskls trochu ty minimální požadavky [pro ten software]?)

BTW where do you come from? You seem to know your way around Czech grammar. Foreigners tend to struggle a LOT with the language.
All of them have had massive security vulnerabilities, and almost certainly (at least Linux and systemd) have many publicly undiscovered ones that are currently being exploited by state actors today.
i doubt it because none of the following stuff is automated in any way. When the follower count drops enough then you qualify to request help and others just get a message asking them to follow the person. They can still decide not to follow the person, in which case they also lose the right to get help from others.

I don't really see how this is more than just a community that supports each other, so hard to see how it would be against the rules.

Yet more vindication for those who disable JS and whitelist it only for a small subset of trusted sites. I should not need to run arbitrary code from a site just to be able to view text, images, and interact with forms.

I remember not long ago I got some confused looks from others for not using the "copy to clipboard" buttons that some sites (which I did trust enough to allow JS on) have around code blocks and the like. They were just as confused why I was not using that "useful feature" as I was why they didn't seem to realise that selection is a built-in feature of the browser that behaves (mostly) predictably and is available everywhere. I'd rather select the text myself than click a button that claims to do it for me.

What for? You already have access to the datacenters.
The food delivery scene is culturally different in india. It’s faster and more efficient (not talking about driver exploitation though). Many of the cloud kitchens OP mentioned in the beginning are quite famous now and were places that never existed before these apps. So it gives confidence that you actually can trust new names in apps in india.

For the most part if you’re discerning with ratings numbers when you choose you should be good.

My suspicion on the business model with this scammer is that they go order from other restaurants after getting and order and get it for delivery. The prices in the delivery apps are generally marked up by up to 50% by the restaurants so you can do a good margin by being a shitty middle man.
[sorry if you're reading in real-time, lots of edits]

It's mentioned briefly in the original article. Cassandra achieves extremely good write performance by being append-only, which means that is disk IO patterns are sequential, with little random IO. This gives great performance on crappy spinning disks. However, with append-only, updating or deleting existing data is handled by writing new data or "tombstones".

When you perform a search, Cassandra still scans all matching data in the table, including that which was deleted. It then uses tombstones to "ignore" deleted data. In other words, lazy delete is great for write performance (Cassandra is optimized for write), but creates overhead during read.

So to avoid killing the cluster during a search, Cassandra imposes a tombstone limit. If a search contains more tombstones then the limit, the search will be abandoned. Real world example: if you're using Cassandra as a time series database and you don't add a sensible TTL to your metrics, a bulk delete would cause searches to suddenly fail, and they wouldn't work again until after compaction is performed on the table, rewriting the whole table minus data that has tombstones older than gc grace period.

Metrics systems aren't just used for eye-baling dashboards during an incident, they're part of your alerting system (usually) so this could lead to missed alerts or false positives.

This is why it's important to continually "age-out" data with a TTL, so that compactions are regularly removing tombstones older than the gc grace period.

"Fucking gc grace period!" (me, on a few occasions)

Why is there a gc grace period in here, making trouble for us? Because Cassandra is a distributed, replicated system that handles partitions and failures, it knows that some nodes may be temporarily unreachable. So it holds on to tombstones long enough to ensure that every node gets them. If it didn't do this, an offline mode may not get the tombstone before it's compacted out of existence in all other nodes. So when it comes back online you get zombie deleted data, back from the dead! Not nice!

If you fuck this up and end up with a huge set of old data that you must delete, you are in for a treat. Easiest option is to manually schedule a bunch of operations to run during a quiet period. With metrics, write traffic volume is pretty linear but read traffic is user-driven. That could mean that quiet period are nightly, on weekends etc. The operations involve checking for downed nodes, modifying gc grace period, deleting a bunch of data and running a compaction. You have to carefully monitor logs for errors, and keep an eye on tombstone limits. Depending on your infrastructure it might be easier to build a new cluster side-by-side, write all the data from the old cluster into the new one with proper TTLs and delete the old cluster. If you're on bare metal and are out of space, you might have to get creative. (To keep a production metrics system running for a few years I had to get extremely creative)

Sorry for the huge thread and possibly wrong info, it's a while since I touched Cassandra, but I still have mental scars from the people who set it up wrong.
But you could jump off at any speed - or get jostled and fall off accidentally if hanging on to the pole that was provided in the doorway. Falling into traffic at 30mph isn’t a bundle of laughs either

My guess is the door requirement was to avoid needing to scrape people off the single lane roadway in rush hour more than a thought for passenger safety and that difference may have got lost on the way to the page
1)

"They absolutely did"

Nope. Which list of people 30 years ago were 'famous for being famous' and which cohort of society aspired to be them? Name names.

It was not 'a thing' aside from a few random, quixotic people. Nobody wanted to 'be them' or thought they could be that.

2)

Yes, we live in different circumstances, that's fair.

But my grandparents were born in homes without electricity or plumbing. They did not turn to prostitution or aspire to the 'least' they could be.

3)

"Why someone's ability which is apropos of nothing "

Because being a great athlete or artists (or scientist etc.) is not 'a propos of nothing'.

Yes, it's a bit glib for people to fanboy athlete's the way we do, and Michael Jordan is a jerk, but he's also a spectacular athlete.
Cryptographic key management is a hard thing for the masses.

Biggest problem is losing the key. Also how to sync the key between devices. Not get tricked into giving it away.

Best case might be a authenticator type of app piggy backing on your phones physical and electronic security.

Most people look after their phones. Then maybe they back up somewhere else.
Also if you go back in time a hundred years, you'll find things using katakana where hiragana is used today (to the point of having full sentences in katakana)
Sorry to be the one to tell you that, but food delivery is here to stay. It is convenient, and at the end of the day, convenience trumps everything. The lesser problems (food being cold, pricing, quality) are simply optimisations waiting to happen, and actually already happening.

What OP describes is an anomaly that should be easy to fix by any platform, and if they are smart, they will fix it - or decay slowly (at least I hope this is what will happen, and that they take Amazon & Google Search with them too).
Isn't that a bit overly reductionist? Cars - I don't really see a significant change. Cars are like [trains, horse carriages, boats] of the past. They provide seating for people to travel. People wanting to travel is nothing new either. Airplanes aren't so different from this lens either.

But I don't think most people would agree that cars aren't a significant change from railroads or horse-drawn carriages. Likewise, one can become an influencer from their bedroom, quite unlike having to travel to Hollywood (or the country equivalent) to become a movie star.
Not really — the “It girls” of the early 20th century were no different.
Honestly? Not to be such savages. With which I mean is that we are hilariously incompetent when it comes to basic rights, freedoms and most of all structuring society.

If we worked together in true unison, we have enough riches/resources to feed, clothe and give a home to anyone who needs it. Just for a moment imagine if the military budgets didn’t need to be spend.

Note I am not advocating any ideology or political structure here, but just the basic observation that we are indeed underdeveloped savages.
A agree with you but I'm not sure the general public does. For a long time The Cheesecake Factory was very popular and they arguably have a large unfocused menu. I'm not saying they're good but giving how popular they were lots of people thought they were good.
I'm not sure crypto and the internet are even remotely in the same ballpark for capability or potential.
This is incorrect. Instagram names are essentially impossible to recover (unless you know an insider) and there’s a liquid market for them.

Same is not true of paypal funds.
Usually if you are intending to even remotely succeed as a musician, athlete, actor, etc these days - you basically have to become an "influencer" by default to succeed today.

I know a few coaches for certain sports for whom Instagram and Tiktok are now far superior ways to acquiring new clients than word of mouth or similar - all their competition has adopted influencer marketing tactics (with themselves marketing themselves), so its evolve or die.
Nice, I first parsed that as Welsh or something, before realizing it was Czech.

The word "prv" is archaic and could confuse some younger speakers, but the sentence works even without the word as "Chrt zhlt hrst zrn" and that's all valid modern Czech.
Lessons learned modeling complex systems, outside the domains of computing and the data sciences, into code.

Over a decade was spent by enterprises designing software using Structured Analysis (data-flow modeling) - lessons lost. Functional decomposition as a design methodology lessons learned - forgotten. Data modeling lessons learned - we are all the way back to people proposing stored procedures for logic. Object-oriented modeling - deprecated, unfashionable and obscured by “its about messaging” or “code organization” in a world that supposedly should be entirely functional.

I like to take occasional tolerance breaks from coffee completely.

I also like to drink much less than the max before I start feeling bad, so that if I have a really long day I can drink more than usual and really feel the effects, without needing to have so much that I have a bad trip(Some of the Starbucks drinks will make me feel like crap with just one of them).

There seems to be studies saying coffee drinkers live longer, and it tastes great, so I do enjoy a daily cup or two of coffee or tea, but I would not want a lifestyle where I couldn't have no caffeine at all most days if I did want to.

I mention this one a lot, but removing a lot of personal side projects from my life has helped me tremendously. I think of it kind of like decluttering, but in the time domain.

I've even mostly changed my stance on open source from "Always use it" to "Avoid things that cause vendor lock in, otherwise prefer FOSS if convenient, but don't hesitate to use proprietary".

Of course you might not have easily discardable projects to free up time with, if you're busy with work or study grinding.
I feel averted.
