Grow your business, fuck college. Also, one little known fact is that you can appeal these rejections. Just write a letter to the head of admissions explaining why you think your denial was mistake, tell them about yourself and your experience.
Convincing someone else that a Show HN doesn't deserve the word "impressive" is not a discussion. It's just boring dismissal, something we have enough in this world and on HN.

"Circle of madness" to me describes what HN would be without all of the effort to keep this place from devolving into a bunch of assholes crapping on every project.

> It isn't impressive at all. It's a toy [...] he completely fails to understand the market. It's a top class r/shittykickstarters.

I mean, for fuck's sake. Is this guy your arch nemesis? Just keep it cool.
You need to break the problem down into chunks with SMART goals. Then you need to define intermediate milestones which you complete within your allocated time period. For example, do a design do before lunchtime. No doc. No lunch. Higher order needs such as food or going home quickly help focus the mind.
Do you find that when you have to do something mentally unpleasant (such as homework back when you were in school / college, or doing your taxes, or whatever similar thing affect you), do you tend to space out? Or do you get a feeling in the pit of your stomach like you are about to be sent to the principal's office (to use an over-used analogy), and you find that you must do something else (that is pleasant) just to make that sickening feeling go away?

If it is the first (spacing out), that could be ADD/ADHD. If it is the second, then it could be fear of failure / depression. If it is neither, then you will need to find a way to re-train your mind, by forcing yourself to see hard problems through.

A professional may need to help you if it is the first two problems. But if it is the third one, the standard techniques is to do deliberate practice, starting off with mild problems and working yourself up through more difficult ones as time goes on (but going back to milder ones and spicing up your workflow with slightly more difficult than what your are used to). Kind of like interval training for physical exercise -- you don't just try to run slightly faster each time, you run at a sustainable pace and punctuate it with something above your abilities for short bursts.

Some people find that they can't do this without a personal trainer. For work type problems, you may need to team up with someone that can help coach you through.

Here's another analogy that I believe carries over. For much of my life, I didn't like tomatoes (except I liked ketchup, tomato soup, pasta sauce, etc). One day I got tired of picking tomatoes off my burgers, or out of a salad, and decided to eat them anyway. After doing this for a few months I got to where I could tolerate them, and eventually start liking them. Same thing with sour cream -- now I love it. And buttermilk. Got tired of throwing out buttermilk that I'd buy for making biscuits, so I taught myself to like it. Now I can't get enough of it.
I was thinking the same thing, are we going to have a mess of contact tracing apps and services with the similar analogy of the incompatibility with differing messaging protocols?

> Also, it's much easier to make it mandatory if it's a system app (and obviously it needs to be mandatory to be useful).

That might work in the case of Apple, Google Pixel and (some) Android One devices where the firmware is (often) manufacturer controlled. Outside of the Google Play Services approach good luck trying to deploy a new Android feature to all the devices out there.
Causal Inference and Data-Fusion in Econometrics (2019)
I work with offshore developers and the general idea is that you're reachable by phone/slack/email off-hours -- both them and myself. Obviously with delay.. but for simple questions/statuses it's not concerning.

Listening now.

Update: Very good points, and I'm glad the interviewers pretty much gave her a format to let her run free and discuss a myriad of points from Viral structure, research efficacy, potential vaccine approaches, and regulatory capture/political failure in diagnostics. She uses how the NIH pulled funding prior to having a vaccine imminent only to have the priorities shift entirely as a recent example of how short-lived memories and fashion can be deadly if this government funded research paradigm alone is how we approach these problems.

She seems like a very knowledge person (beyond her academic concentration) and understands the implications to other catastrophes when dealing with an unnecessary bureaucratic-political maze, its just not suited for foresight or critical crisis management. Its a best reactionary in a knee-jerk manner, and fails at scale in a catastrophic way. She makes a salient, albeit alarming, point how this can be seen with how climate-change is being mishandled.

I'd like to get to know more about her and her work, highly recommended podcast.
If the OP just wants to share the media to a friend, why not directly send the file or share the link of weebly ?
Why bother to indirectly transfer the media via YouTube or vimeo ?
Yes very well put. I like the line about "investing in bat-shit ideas they now cry about not having solutions for bat-borne illnesses".

This sort of reactionary call to arms does us no favours.

We need a new class of investors as you correctly identified.
They are international; it's just that outside of the US the quantity of posts is much lower as people use local alternatives.

Also a large portion of craigslist here was just the personals section - once that was shut down there is basically no good reason to use it anymore, as it simply doesn't have the network effect / critical mass of users to sustain itself. The remaining users all seem to be work-related scams of some kind (probably automated) and drug dealers (probably cops).
I'd say all of them, particularly the state media which have journalistic policies that allow them to skirt the issuing of retractions for months (ABC) or not at all (SBS). At least the private sector media will retract and correct in a reasonable period of time, in my experience both Fairfax and News Corp, although they're also generally rags at this point.

What happened to those GM spider goats with the silky milk? (2019)
Grrrr. It's efficiency is based on using a fuel cell. There seems to be a few ways around of storing Hydrogen in clever ways - this just adds to the list. But until we discover unobtainium that's as efficient as platinum in fuel cells but common and a fraction of the price, it's all a pipe dream.

Had they burnt it in an ICE, and come up with those figures then OK. As it is, when using technology that exists now it won't be 5 kg per 500km, it will 25 kg at best, and 500l of this material will be required.

It’s irritating when Medallion is identified as an investment fund, instead of what it is, a market maker.
I don’t understand your second question — they printed a bunch of martensitic steel tensile specimens with a pretty common laser melting technique, then ran a bunch of mechanical testing. Where’s the lack of execution?

I think the art/science thing is just a bit of editorializing, it’s sort of accepted that a lot of the fundamental science behind metal additive manufacturing is just not established. I.e. it’s far from trivial to just set up shop and print an alloy that hasn’t been printed before.
Increase pain tolerance.
Nice explanation of why it was called Event 201:

In recent years, the world has seen a growing number of epidemic events, amounting to approximately 200 events annually. These events are increasing, and they are disruptive to health, economies, and society. Managing these events already strains global capacity, even absent a pandemic threat. Experts agree that it is only a matter of time before one of these epidemics becomes global—a pandemic with potentially catastrophic consequences. A severe pandemic, which becomes “Event 201,”
Given the results in developing countries I’m not sure you can say that. It could very well be that the increase in GDP more then makes up for any costs of such policies.

Hello, I'm a developer behind it. Can you tell us which OS you are on in both phone and desktop? And does both the devices are on same network?
I don't understand it either but that doesn't lead me to leap to a conclusion that Apple's and Google's expert cryptographers and system architects don't know what they are doing. I instead blame my own current ignorance, and look forward to gaining more understanding.

But yes as a user, personally I'd prefer to use and trust an app supplied by my OS provider, mandatory or not, built in to the OS or not (and plenty of Apple apps are optional after-the-fact downloads, so it need not be a forced download unless there are reasons for that that overcome all the negatives).
Same news from the Associated Press: https://apnews.com/8ca7559d39b89d097a158043ca8f44bc .
Yes but we know quite a lot about its spread and impact now. This is like the fog of war, its hard to see what is happening while a battle is underway but afterward many different accounts can be pieced together to gain an accurate understanding of what happened.

Where would Snapchat be without their trending (garbage) screen that nobody looks at? All emerging social media totally ignores news. Instagram? Almost zero news. Tik Tok? No news. Snapchat? Garbage clickbait nobody looks at.

Facebook is the antiquated ugly stepchild of social media. What's their engagement like for people <18?
Not much of a simulation [1] anymore. Lockdowns have to go strict imo, but with this inept administration in place I have little hope. :-(

We don't really do that. We'd rather have an engineering blog, but that too requires someone to write about technical things we do, and we'd rather do technical things (fix bugs or add features) than write about them at this stage...

I exchange on HN however.

We're too busy putting out fires with our first users. Product depends on systems we don't control and users work late into the night, so we also do support on Slack around the clock.

CEO writes a column for a newspaper sometimes and posts the link to social media pages. But the columns are not about the company.
What's interesting is the extent to which the real pandemic seems to have been handled better than the simulation, despite what is objectively a less effective federal response than the one envisioned (in practice, the actual federal response seems to have done more harm than good as far as disease control goes -- the one bright spot was the economic response).

It turns out that a few early mover states were more willing than expected to institute rigorous lockdowns, other states followed on more rapidly than expected, and the population as a whole (even in states with less effective responses) was... actually fairly well informed and took appropriate action.

Basically, we stayed home and beat this. Now we need to finish the job, of course, but absent some kind of crazy change in public behavior we're not going to see the doomsday numbers that everyone was worried about.
Do you think Google is more likely to share revenue, or to cut off those content snippets and shutdown Google News?

> still need nearly everybody of working age to work

Within my entire known family tree maybe 1 in 8 people work jobs essential to the creation of goods (including food, power, water), the construction or maintenance of shelter, or the providing of health or transportation.

A huge swath of society is employed in doing things often equating to simply moving numbers around in databases or inside heads. Or more generally, they serve economics by operating to move money from one pocketbook to another.

Its also worth mentioning that labor force participation rates trend downwards over the last 50 years in industrialized nations. Since the participation boom of womens emancipation there has been a general decline in participation not reflected in unemployment figures largely because the number of people required to produce the needs and wants of 99% of everyone else is so few, and because there are so few of means to create demand all on their own (ie, millionaire+ elites) for more extravagant goods markets that don't manifest in a widespread form.
Thank you for sharing your experience.

Would you say your ability to visualize has declined, or you’ve just favored other methods of thinking?
Our politicians live for today. They could care less about tomorrow. You can see this in all areas of “preparedness”, and it’s especially obvious in debt and pensions. No surprise here that our government was auctioning off ventilators and exhausting without replacing PPE gear stockpiles without a care in the world.
I have this (at least by the sound of it: if totally different, maybe something is helped by this anyway) (and had it for for 35 odd years). I was told I can ‘achieve anything’ during my childhood which, somehow is a signal to my brain to pick the things I definitely can do and leave the harder things because it might actually show I cannot ‘achieve anything’ (duh, ofcourse I can’t, but it is not a rational or even conscious thing anyway).

Luckily I found a mechanism to cope with that very early on; I build a ‘story’ around the task/project/thing that I want to do but also ‘prove to my brain’ I am ‘all that’ (so I don’t simply don’t do it as is the first instinct); basically to narrate that this is only the first step and it will probably be crap, but it will become that shiny perfection that was promised later on through iteration.

I do this with everything; cooking, software dev (where it is actually the normal way things work), hardware, management, sports, etc. Some things go ‘perfect’ the first time, most obviously do not, but they either become irrelevant or get better (and even perfect for some definition).

That way, I am mentally shielded from not doing them in the first place because of my mental block. This used to be (in my teens) an actual narrative with myself where I told myself a story how something would go; starting really badly and insignificant as possible and then building out that narrative up to castles in the sky. Coming back down I would then be able to start the journey at the bottom while genuinely believing I would get to the top ‘in some time’ (it really does not matter if you do; the starting and iterating matters the most imho). Now the process is automatic, but it still has that same feeling to start with; I will never get over it but I managed to cope.
Only for short distances. At long distances, they lose power due to resistance in the wires. Underwater power lines across oceans are also extreme expensive.
The map is an infographic that displays bubbles/gears proportional to a country's GDP (manufacturing only) worldwide.

The blog author then extends the analysis by including three tables about GDP and per capita data, along with footnotes/sources.

These tables are interesting and reveal insights about Germany, Ireland, Iceland, Norway, Switzerland, and the Top 10 Countries by GDP Manufacturing (China, U.S., India, Mexico, South Korea, Japan, etc.).

The U.S. is #2 regarding GDP Manufacturing, but #1 for GDP Total. The U.S. also has one of the largest GDPs per capita (not in the top five, though -- according to the tables).

Maybe I or someone else might want to write a Python script (pandas, etc.) to analyze the data set further. There is a link to the data by the United Nations and one other source.
For blockchain to be useful, your use-case has to:

1) Involve coordination between parties who don't trust each other; if they trust each other, a regular database will do fine and be much more efficient.

2) Exist completely within the ledger; once something is in the ledger it's tamper-proof, but bad information can still enter the ledger from the outside world. This is the reason it doesn't serve much purpose for anything physical, like delivery confirmation. If someone wanted to fake a delivery they could just... enter fake information.

That makes for a very narrow set of legitimate use-cases, most of which are crypto-currency, whose status as a "solution to a problem" is dubious at best.
Perhaps, though I once broke a 1L bottle of ammonium hydroxide (a strong solution of ammonia) in the lab. We literally couldn’t go in the room for 15 min. That was just 1L of not 100% ammonia, and we had a door where we could get out. Even if the ammonia isn’t flammable, you might kill occupants of a car with what is effectively a poison gas.
One of the key findings: "The United States lacks the production capacity to meet the demands for protective equipment and medical devices such as masks and ventilators imposed by a pandemic"

This is exactly why we can't have the government move like molasses. We had several months, needed to react with urgency and failed.
If we had patient zero the outlook could have been even worse.
The parent comment is another situation on HN where (as I write this, anyway) a straightforward, relevant and constructive statement (it's just a link to a news article about exactly this subject) gets downvoted heavily for, as far as I can see, purely partisan reasons. And I only ever see this happen in one direction, politically.

Can we really, as a community, not link to the New York Times without it being "controversial" and unwanted?
I typed gibberish username/password into HN and successfully logged in
This account was apparently created in 2012. Just thought it was pretty crazy that I typed in random gibberish and happened to land on a valid account. What are the odds?

I was trying to enter invalid credentials so that I might see what error HN provided.

It's funny... It seems like every line of code I'm writing right now after a long day is causing errors. If I can't even unsuccessfully log into a website on purpose, then it really is time for a break.

If I've hijacked an account for someone who actually uses this, I apologize. Logging out now.
Are you able to discuss what you're working on? It would be very interesting to hear more about it if so.
CFR is not IFR, it's not even particularly helpful or meaningful because it varies so much by demographics and hospital capacity.
Hmm. Interesting food for thought.

If we also added the following conditions:
- All agents of the government sign their commits
- Whenever a commit is made to a copy of the repository (perhaps all government agents make a commit to a single repository hosted by the government) then there are several independent parties that make copies of this commit, and in addition there exists a mechanism to establish consensus between these copies of the repository when a conflict arises

THEN we might have something that could replace a blockchain.

Conversely, if the government agents all committed to a single repository and nobody bothered with making immediate copies and consensus, then the agent could double spend / rewrite the repository.
Do you use the screen reader for your code, too? How do you debug your code?
Multiple rounds of aerobraking and landings in deep gravity wells is vastly different than Hayabusa 2.

And Mars is eminently survivable for humans, far better than the moon for example. Starship makes landing a few hundred tons of food, supplies and equipment before the first crews relatively easy.

ISRU experiments on earth have proven the concepts already. We can figure out ISRU details along the way, even if it takes a few extra synods and delivering more equipment. we will be getting far more science out of a human landing than robots can ever provide.

In fact, the first humans on Mars will explore more of it in a few weeks than 50 years of rovers have done. The first human to take a single shovel full of Mars will have have dug deeper than than the Insight orbit has done in a year of trying.

Benefits of cold showers (fights depression)
I really wish someone would publish this with larger examples. Checkouts are great, but some of us are working on larger systems with 25+ fields and most of that required, or dependantly required, and no, wizards apparently just confuse our users.
I’m actually surprised at how compliant citizens were in general. I would have expected more rioting or pushback but I guess that’s what we are seeing right now. It’s been 6 weeks and I’m surviving but my wife and kids are not doing as well. I can only imagine how bad some people have it, especially those in apartments. At some point people are going to do the math and figure that 80% mild symptoms rate that leads to immunity and a decent job is worth the risk rather than starving to death alone. I think that breaking point will be reached before end of June and I hope there are measures to deal with that. Personally I would give everyone $2000/month and drop prices of marijuana to keep the masses from rioting.

shows a significant drop in caseload. There might be herd immunity effect if you assume a death rate of ~0.2%.
Basically everything you said is wrong. The costs of fuel cells are dropping so fast, that that is probably the main driver of interest in fuel cell technology recently. The filling stations are being installed by dozens around the world right now. Fuel cells have reach 60% efficiency in real world testing.

It’s been something of a blind spot among tech workers that they are completely oblivious to the gains made in fuel cells. For all the hype about us being forward thinking, a lot of us are seriously stuck in the past.
I still want to see how Sweden ends up before we pat ourselves on the back.

And I know it’s quite the contrarian viewpoint but it remains to be seen if the cure is worse than the disease. How many small businesses and livelihoods have we lost? How many suicides? How much unemployment?
Indeed but that's not evidence of re-infection. That's evidence that re-infection should be thoroughly investigated. Rather, it's evidence of smoke not evidence of fire.
I've played dota for a while and used to feel this way. It's still not something I'd recommend to get smarter, but if you feel like it's making you lazy try staying focused while you're dead. Personally I just think about what I/my team could have done differently (or if maybe my death was a good trade). After minute 30 or so you spend upwards of a minute dead, if you just go and check reddit or whatever it just reinforces hard thinking -> extreme mind candy (or at least, it did for me).

Plus you'll probably improve, I rose a few ranks after starting to do this.
> The article is entirely premised on Apple and Google not giving users control over whether tracing is enabled.

There is precedent for this. For example, android periodically scans Bluetooth and wifi devices even if you have those turned off. There is no indication to the user that this is happening. And as far as I can tell, there is no way to turn off this behavior.
