From my experience the two biggest pitfalls to startups are lack of product market fit and execution.

Product market fit is the hardest thing you have to do. Sometimes the current products are good enough or no one really wants the product. You also have to consider whether its economical. For instance, there may be a demand for flying cars but its uneconomical to driving, so it doesn't really work as a startup.

The other problem is execution. Take the high to medium end electric car market that sprung up after Tesla proved product market fit. There are probably a dozen electric car manufacturers that don't actually manufacture electric cars for sale. That's because its actually very hard to do that. It's easy to create a pitch deck and even a prototype, but shipping cars is hard.

A start up with no product has not proven either of these. They don't have product market fit because their idea has not been tested in the market yet. And they certainly didn't execute yet.

Compare that to a company with 600k+ a year revenue. They may not have proven the economics aspect (they're probably losing money) and they may never prove it. But they have proven that someone will pay for their product and they can create and deliver a product (assuming revenue isn't pre-sales). So if you were to compare to a few guys with an idea and a company shipping real product, I would think the one shipping is a lot further along and deserves a higher valuation in general
Your Pa$$word doesn't matter (2019)
Russia tried to execute on their normal "Deep Battle" doctrine where they attack from multiple fronts simultaneously and culminate towards the same point.

The problem was execution. Military analysts expected exactly that, but Russia failed in operations. See here on March 4th when it started becoming clear the operation was botched [1]:

"They [Russia] have also continued conducting operations in southern Ukraine along three diverging axes rather than concentrating on one or attempting mutually supporting efforts. These failures of basic operational art—long a strong suit of the Soviet military and heavily studied at Russian military academies—remain inexplicable as does the Russian military’s failure to gain air superiority or at least to ground the Ukrainian Air Force."

I feel like, given the negative connotations of "Facebook", that's by design.
Can we please keep this type of rants and off-topic criticisms out of technical threads? Lately even reading technical threads has become difficult because of thread-hijacking off-topic rants.

> Speeding is one of the largest behavioral contributors to traffic fatalities

Yes, this is true. In every study that's been done on this matter in the US, it's been determined that drivers who speed have a lower probability of getting into an accident, but when they do it has a higher probability of being fatal. At basic pass, this makes sense, as there's more energy involved in the crash if one or both drivers are at higher rates of speed.

Why this doesn't bother me, is because I'm not concerned with behaviors that increase or decrease fatality, I'm concerned with behaviors that increase or decrease the risk of an accident happening in the first place. Speeding does not cause accidents, and all of the evidence supports this. The motorcyclist /does/ cause accidents, generally fatal accidents (although only for themselves).

Some things I like to ask myself when his name inevitably comes up:

* Is he being stupid?
* Is he promoting something? If so, for who's gain?
* Is he lying?
* Did he let the wrong thought out of his head and piss people off?

Nobody in his position would be too thick-skulled to see that his biggest fans aren't the sharpest tools in the shed. Consider how he's treated his own employees, and ask if you think he's above poking and prodding his cult following to his own ends or entertainment.

a muddled brand is better than the currently maligned harbinger of misery disinformation and insurrection that Facebook has been mired in. Recruiters at Meta probably appreciate the distance.

Someone speeding on the highway is different from someone speeding on a busy residential street, which is where it is most likely people will be around to use such an app.
Those same stats are true for EVERY social media platform. Twitter is not the exception here. What percentage of Reddit users do you think comment on a post? What percentage of hacker news readers submit new posts or write comments? Instagram content consumers vs producers?

Most people are followers and that’s ok. You can get off your soap box now.
How about 1024 colors on CGA? https://int10h.org/blog/2015/04/cga-in-1024-colors-new-mode-...
Interesting that he filed his >5% report on Schedule 13G rather than Schedule 13D, and has checked the box for the exemption in Rule 13d-1(c)[1]. This exemption requires that he "has not acquired the securities with any purpose, or with the effect, of changing or influencing the control of the issuer, or in connection with or as a participant in any transaction having that purpose or effect."

If he's indeed seeking to participate actively in changing things at Twitter, he may have opened yet another front in his antagonization of the SEC.

[1]: https://www.law.cornell.edu/cfr/text/17/240.13d-1

Background: the SEC requires purchasers of >5% of a U.S. public company to provide certain information about themselves and their intentions in making the purchase. Generally, you file Schedule 13D if you're seeking to conduct a takeover bid. The shorter Schedule 13G is supposed to be used only for "passive" investors.

Here, perhaps Musk would say he's not seeking a change in the "control" of the company (voting share ownership), just a change in governance practices not involving a change in control.

This will be interesting...
hm, I disagree with that. I think all signs point to Jack being a true techno-utopian of the old 90's Wired magazine era. If that’s true, then it makes perfect sense that his tech-hippy leanings would be incompatible with turning Twitter into the FAANG-grade blockbuster that his investors were banking on.

And crypto of course slots neatly into that same Wired/Jaron-Lanier/early-Burning-Man sect. I think this is a case of the simplest explanation being the likeliest: He's telling the truth, and he's a huge dork.
Why don't you do this? If you don't have resources for this, why do you think other people have them? Ask yourself honestly, if you won a lottery yesterday, would you give it away to those workers in underdeveloped countries? I would not, because I'm too greedy, but I don't think you would really give money away either, and I supported Ukraine with about $100, which is probably the biggest donation I have done in my life, many people could live on it for two weeks where I live. Many options are available, but not all of them are as good as just giving them jobs. And if you wanted to give them better paying jobs - who will pay? Would you pay more for some laptop because it supported some unknown person on the other side of earth? Why don't you just send them some money today? You have that option after all.
Why aren't pollutants (chemical and noise) safety considerations for humans?
This thread is irony- there are 100 things you can split your focus between....to help you develop focus....

Which is not wrong. The path of behavior change is unique, as each individual has their own unique cognitive architecture, history of experiences, expectations, habits, etc. Changing behaviors toward goals is hard. There are common threads across people, of course, and every technique has been utilized millions of times across millions (billions) of people. But your journey is yours alone.

What I hear just in the snippet above is someone who is dissatisfied with themselves, and has a solution hypothesis- "focus"- but that may or may not be the real solution or path to satisfaction.

All of life is a process of getting to know oneself better, and coming to understand the circumstances in which one succeeds and is happy, and understanding what one has to continually forgive oneself for, because everyone is flawed and fails most of the time.

I would encourage trying to spend more time in the "problem domain"- analyzing the dissatisfaction- and with the phrase "kill your darlings"- as so much of what we sometimes see as having potential turns out on reflection to be wishful thinking.

Good luck and best wishes.
No, I didn't. Try reading it again.
Nothing pre-built, but you can cobble something together yourself – query the DOM for stylesheets, evaluate their attributes (i.e. especially the "title" and "alternate" attributes) and then enable and disable them as required.

I wrote something like that for my homepage, although as I only needed to switch between two styles and I'm not a front-end person, I didn't bother with an actual selection drop-down and just wrote a toggle that cycles through all alternate stylesheets one at a time.
The issue is less with the regulation, but with site owners who try to collect as much information as they can, then make cookie banners, which are more complex than requested by the regulation and then put blame in EU in order to annoy everybody to create pressure on the EU instead of simply complying with the requirements and respecting users.
I mean, even the IIGS wasn't really an Apple II in a real sense. Classic Apple II programs did use the IIGS' CPU, but were otherwise basically running on the MEGA-II (which I think is also how the Mac LC did Apple compatibility, although I've forgotten). Writing programs for GSOS had more in common with Mac programming than the Apple II, and properly using all of the GS's advanced sound and graphics required entirely different code from an Apple IIe. The 65816 also had a lot of practical issues stemming from the global nature of the 8/16-bit toggle that would've only gotten compounded if you tried to naively extend the architecture to 32-bits.

In the end, yes, I'm very curious what extending the Apple II line would've looked like, in an academic sense. But I suspect that, by the mid-90s, the "Apple II" would've been as technically unrecognizable from the Apple IIe as late 90s PCs were from the original XT: lots of echoes and lots of backwards compatibility, but extremely different when properly and modernly used.
Yes, but companies have mostly chosen the most annoying method they possibly could have to implement that. If either non-strictly necessary cookies were required to be off by default, or there were a button that does the equivalent of denying all non-essential cookies, then you'd be halfway there. If it weren't a modal, but a small banner at the top or bottom of the screen that allowed you to operate with non-strictly necessary cookies turned off and gave you options to turn them on, that would be even better.

I guess the EU just needs better product managers or something.
>Real power is the power to kill other human beings and not suffer any consequence for it. We don't usually talk about that when discussing politics, but this is what aspiring leaders really crave.

Well put. It makes sense in that context that Musk's fans think he has no interest in politics and his detractors think he must.

As insane as Musk's fanbase can be, I still find his detractors' view of the world less realistic. There's a metric to assess that opinion by. As a fan, I predict he won't run for political office on Earth.
> It's really a very reasonable rule.

Impact on users is annoying pop up every time you visit a new web site, which ask s for permission to store cookies. It doesn't seem like a reasonable rule. Storing cookies is reasonable. That's how the web works. Don't need special permission for it, and asking for permission every time serves no purpose other than irritating users.
I don't think Twitter has a problem, I think companies who use Twitter to plan their strategy have a problem. Companies who spend money to look good on Twitter, companies who pay ad companies who use Twitter to design their campaigns, etc etc.

Anyone who thinks Twitter is an accurate representation of the general population is building houses on a sand beach.

> Proper investigations will be done and Russia will be brought to justice in front of a court of its peers

As the US passed a law to invade the Hague in case the ICC ever tries to accuse the US of war crimes, I'm assuming the US is not a "peer".

> Defending this monstrous state with your "concerned" deflections while mothers and children lay raped and dead on the earth of Ukraine is not defensible. Please don't do this here.

Israel was murdering Palestinian children in the West Bank and Gaza last year, backed by the US. Accounts of that posted here which managed not to be flagged were heavily "defended" with concerned deflections, where are your comments all over those threads to not deflect and do that here? Or the ongoing Saudi massacres of Yemeni, which the US backs and are happening now. Or the US drone attack on children in Kabul last August? When are those war crime trials starting?
While I don't do only 20 minutes. I found that setting the digital wellbeing setting on my phone really helped.

Focus mode during the day time on weekdays, to prevent stuff while trying to be productive. And timers on a few apps.

I used to scroll through far too much twitter, but putting an hour cap on my phone helped with that a lot. It helped break the habit, and depending on what is happening in the world, I may not even hit the cap many days.
I don’t want to be curt but you can just look it up.

> safety […] is the purported reason behind speed limits & their enforcement.

A reason, among several others. See, for instance, the most famous speed limit ever enacted:

https://en.wikipedia.org/wiki/National_Maximum_Speed_Law
so they have white collar jobs.
They don't have a monopoly over public discourse though, not even remotely close.
PNY makes a bunch of USB 2.0 flash drives with blue connector. I bought a couple thinking I got a decent deal and then realized my mistake when I saw the copy speeds.

Infuriating.
I really, really hope this is a sign of big changes. Board takeover, C-Suite cleaned out, Coinbase company culture installed, open algorithms, open moderation, removal of company bias. That would be incredible.
It would be better if Meta would focus on detecting spam at scale.

I put a desk chair on Marketplace last Friday, and got 8 messages that were actually scams. These were trying to "schedule" a Fedex/DHL pickup, and would redirect me to fake branded websites that were requesting my personal details and bank account. This was so obviously fake it baffled me Meta can't detect these automatically.

I am also getting multiple message requests per week asking from hookups. These are obviously fake [1].

A bad test is worse than no test.

This is a very bad test. Cute paper, but I hope anyone foolish enough to try and deploy such an app gets a strongly-worded letter from FDA.
Logical/vector clocks etc can be a real pain with ephemeral clients like web browsers, it can be hard to work out when it's safe to trim the now dormant nodes.

Though to address the GP a bit, the problem of concurrent writers without a sequencer (like a database) is less common than you might think. It definitely still comes up and there are things like CRDTs to help you address these cases (which do generally rely on either logical clocks or hybrid logical clocks). However most cases of event streaming to the browser you have each write round-tripping through the DB anyway and you use a feed like this to push a CDC stream or similar down into the browser to get "instant" feedback of a change that occurred after initial load.
I'd rather be tracked than inconvenienced.

Go away banners. They are annoying.
I'm all for it if I can use the same app to report drivers who drive both under and over the speedlimit (25 in both a 30mph and 20mph roads). It seems to me that more than half of the drivers that I'm stuck behind are either dangerously distracted or dangerously incompetent at maneuvering their vehicle, as they generally have poor lane hygiene, they do not observe the speed limit.
Will I also be able to report road users that hold up significant amounts of traffic behind them without stopping and passing them?
In fact, leaving is likely what they want you to do. Drug kicks in, they pose as the Good Samaritan or friend taking the clearly drank-too-much person home.
But if it's valuable to you, then surely it's equally (if not more) valuable to unknown 3rd parties. /s
Cookies serve a purpose. They can't just be used for serving ads that follow you.

Case in point: the very website we're using right now. While it's true that Hacker News would be possible without cookies, for commenting and voting you'd then have to log in each time your browser session has been closed, which would make for a less than optimal user experience.
Does Choice Cause an Illusion of Control?
Physical reality is barely changed by peoples' emotions (small shifts in their biochemistry).

Physical reality is very often changed significantly by the choices people make, which are rooted in their emotions.

So, while the universe as such may not care about emotions, they still matter as long as you're interacting with humans (including oneself).

FWIW, I'd not heard of alexithymia before, and I now am thinking I may have had it most of my life.

I've gotten much better at recognizing emotions in myself and others over the past two years through a combination of prayer, therapy, introspection (a skeptic might argue my prayer was just an obscured form of introspection), and reading (Non-violent Communication by Marshall Rosenberg helped me immensely).

I've seen the world become much more comprehensible as this has changed - other humans are a big part of the world, given how dependent we all are on civilization for survival and thriving, and as hinted above, I now understand my own actions and choices much better too. Not being able to recognize my emotions didn't mean I had none.

I was explaining why your worldview of non-violent speech having no negative impacts on others is misguided, but instead of engaging with that point you decided to withdraw into immaturity and sarcasm. Have a good day.

Penny is comparable to Lidl and the two Aldi chains, and is owned by Rewe. Rewe itself is a bit more expensive, roughly comparable with Edeka.
Can you support this claim?

Also it seems backwards - the UK got close to increasing its speed limits on motorways recently. The tradeoff was between economic benefits from more efficient travel on motorways and increased risk due to the higher speeds. The discussion was supported with ample data, although I believe it didn't succeed for political reasons.

You're suggesting almost exactly the opposite.
> we emphasise explaining the context two levels up. I may tell my soldiers to raid a compound, but I would also tell them that the reason for this is to create a distraction so that the Colonel can divert the enemy away from a bridge, and that the reason the Brigadier wants the Colonel to divert the enemy is so that the bridge is easier to cross.

many organizations could benefit from more of that.
Long ago I setup uBlock Origin with some Cookie-Banner and Annoyances specific rules.

I disagree. I was a twitter user before the retweet button appeared. We all got creative to effectively RT others without the need for a button. The button appeared because users organically developed the retweet and the button just made it more convenient.
Maybe instead he has realized the value Twitter has to these individual news organizations.

He’s going to cut the head off by redoing the algorithm and establish an insane amount of power / influence by reducing everyone else’s.

Bezo's "philanthropic" Washington Post purchase just became honest.

Every popular power account and blue check mark is about to get blown up. It's no secret he kind of hates them.
