> This past week I've become obsessed with a video game idea. The week before I was obsessed with a design app that I'm working on.

But why? What was special about the video game idea that interested you, and the same about the design app?

In my experience I often fail to see things through because they only interest me superficially or are primarily orientated around making money (quickly!).

But I know what I actually want to do (and I'm working towards it), and the reason is that I feel that activity has merit on so many deeper levels than just making money or the intellectual challenge of solving a problem. It aligns more with a sense of purpose than anything else.

So for me now, that's my yardstick. I may still do side projects that don't align with that core goal, but I don't expect too much from them - in fact if they were to actually take off they may get in the way of my core goal which would make the "success" seem pointless.

Perhaps through questioning yourself and digging into your motivations you'll be able to find something that you'll be able to stick with when other things come along competing for your attention.
That would only save money if the zero-based-budgeter is willing to fire all the humans who are making up bullshit to justify their budget.
What HNer henry_flower neglected to state explicitly in his helpful comment is that it is false that pressing C-s to go to the next result is hardcoded in some Emacs Lisp function. I just wanted to say that in case non-Emacsers don't know it's implied by what Henry did say. (What he said is much better than just "that's not true!", he also tells you how to change the C-s key that goes to the next match.)

If you are able to check whether you've been in a "dangerous" space-time box yourself, then you are probably also able to check where these boxes are, I suppose? One way would be brute force hashing all possible space-time blocks and comparing with the public hashed list. This mechanism was why I abandoned the space-time box approach to begin with - but if you have an idea for a workaround, please get in touch!

Ask HN: What's your work journal solution?
Over the past few years, I've tried a few variants:

1. Local file + vim：https://www.jakehao.com/vim-work-journal

2. Github issue：https://www.jakehao.com/github-wiki

3. nvAlt + Gmail + Awk script：https://www.jakehao.com/gmail

I've failed to use #1 and #2. My motivation faded away at some point.

I am currently using #3 that is inspired by one of PG's tweet:

https://twitter.com/haojianzong/status/1236068095451488257

What's your solution? Would you like to share?

I wonder if there is an updated version of this wonderful resource by Norvig. I read it about 12 years ago, and I still found it so useful.
In general, all the work by Peter Norvig is so clear, simple to read, and enjoyable.
But can you know that Germany is an outlier? Germany likely has a higher reporting rate than China so its numbers should be closer to the truth.
No argument that emacs is getting better.

But I'm not sure it will ever be what I would consider high-quality!

I think it's just the nature of a huge system implemented (mostly) in a dynamically typed, dynamically scoped (!) (though, happily, more and more less and less) language to be partly broken all of the time.

And, to be fair, most of the bugginess is not emacs per-se, but in the various packages and their interactions -- but what is emacs, really, other than a platform to run the packages?

So here's some random problems I have (I have a long list, and occasionally I try to fix one; the list is growing):

- After I run a python shell for a while, bash shells stop asynchronously showing command output; the shell just hangs until the command completes.

- There's an awesome mode iedit that lets you edit all instances of a symbol. Sometimes, for certain sequences of characters, instead of correctly performing the edit, it inserts gibberish.

- There's an awesome mode grep-ed that let's you edit grep(†) results inline; very convenient. Except for when it very rarely, randomly decides to garbles the files.

(† Or even better ripgrep -- random shout out to truly fantastic piece of software!)

- The afore-mentioned iedit mode doesn't work w/ the delete-horizontal-space editing command. (All other commands, yes, just not that one, for some reason.)

- There is a mode dumb-jump that jumps to symbols. There is an emacs feature to soft-wrap lines. Dump-jump doesn't work when jumping to a symbol that's on a wrapped line.

- To work around a rare but tricky race condition, emacs shell mode at some point added a built-in 1-second startup delay. I lived w/ annoyingly slow shell starts for months before I finally tracked it down, only to find out it was on-purpose terrible kludge!

- The soft-line wrapping mode (visual-line-mode) goes crazy if the line gets really long.

&c &c &c.

So while I spend most my time in emacs and have great affection for it, I definitely don't feel like it's a high-quality experience. I'm constantly running into little bugs.

To be fair, most of my arguments are with 3rd-party packages and their interactions, not emacs per-se. But emacs w/o 3rd party packages would be like a non-fat decaf latte: what's the point?

(P.S. Very excited about the possibility of fixed long lines & tree-sitting parsers!)
I do that too. The top slot in my mind flips between ideas on a weekly basis. Last week it was a videogame. This week it's worldbuilding. Next week it might be something for the job, or it might be an Emacs mode, or who knows.

One thing I've noticed though - regardless of whether or not I do something about my current top most exciting thing, these things come back. The same videogame idea has been visiting me regularly for the past six months. This means that even if I lose steam after a few days of working on something, it's not work lost - I'll probably resume it for a bit a few weeks or months down the line.

On top of that, I've learned to not consider any hard intellectual work as wasted. Things I've researched for random harebrained ideas I later flaked on often find a way to become useful in my dayjob, or a different harebrained idea.
That video is really talking mostly about EPA report on impacts in the US, and doesn't particularly deny the science. But it doesn't have much to do with the article posted here, which talks about a very specific point regarding modelling likely impact of temperature changes on electricity consumption.

I actually agree that the report and the science in general could be a lot better presented. It's not clear exactly why they've picked those ranges for the presentations referenced in the video, and it leaves it open to accusations of bias.

The summary referenced in the opening of the PDF is at https://nca2018.globalchange.gov/downloads/NCA4_Report-in-Br... page 28 - an unwieldy PDF, with difficult to follow and vague references. (E.g. "Sources: (a) adapted from Vose et al. 2017, (b) EPA, (c–f and h–l) adapted from EPA 2016, (g and center infographic) EPA and NOAA.") - I can't immediately see the source data in that reference. It doesn't exactly make it easy to understand what's going on and why.

And another source he references https://science2017.globalchange.gov/chapter/6/ mentions the increase in heat waves in the 1930s without suggesting a reason. It would be more helpful if the video actually referenced the source as a link in the description of the video rather than forcing interested watchers to copy out the link. Basically - poor presentation in the video and in the reports it references.

Furthermore, it's clear that the examples analysed in the video have also been picked out to make a point. Not very encouraging from either side really. The answer is more science and better presented science, and the fact that this video, like much of the sceptical analysis about climate change opens with a political point shows the motivation clearly.
Ask HN: Can the Corona virus fix global warming?
It seems like people travel less, especially internationally for either business or holiday. More companies are switching to remote, at least partially. Economic activity is shrinking in many areas.

Does it also mean that carbon footprint will be meaningfully reduced globally? is there a bright side to this scare? Or is it like a FAD diet, and the world will bounce back and gain all the weight right back?

> Two major versions with breaking changes per year? This seems a bit too fast paced for my taste.

They provide LTS releases (similar to Ubuntu). I'd definitely recommend sticking to them for projects that are / will be in maintenance mode. The breaking changes are usually minor, so for actively developed projects, using the regular versions is fine.
> do not love, next!

Ha yes, how will you find anything if you already have everything figured out?
Have to sign in to even browse around. No thank you. Rather not have you own my information for life.
Scrolling sounds like a terrible way to get around a file. I'd much rather be presented with a prompt to go to a named "section" with completion (an actual section in a prose document, or a function definition in a program), or to search for some text. Or, if I don't have a specific target in mind and I want an overview of the file, I prefer pagination to scrolling.

But... I wonder how much my preference is conditioned by years of Emacs and its subpar scrolling? My preference for pagination+search extends to other software; to browsers, for example (spacebar or ctrl+f over mouse-wheel), but is that just a habit I got from my constant Emacs usage (I typed this comment in Emacs)?
> Satellites are also battery powered.

I thought they have solar panels.

Also, don't phones and satellites use small antenna arrays to direct power in a certain direction?
Capability-based computer systems. (1984)
I've heard that everybody is connected with a surprisingly low number of intermediate steps. Maybe now would be a good time to try that out;-) So, if you know anybody...
Yes, all the time. I frequently need to know who made a change, what ticket was associated with that change, when was it made, what did the code do prior to that change, etc. We did make the change to git almost 10 years ago. I wasn't directly involved, but we managed to do it in a way that largely preserved history.
Expecting local officials to deal effectively with extraordinary circumstances is unrealistic. A wealthy populous nation should be able to support a team of national experts to assist in times and places of particular need, in a variety of fields including that of infectious disease. The system described in TFA seems rather more like a struggle among competing cults of personality. "Your mayor sucks! Now you will be ruled by our super-mayor!" "Does he know a single thing about health?" "Who knows?! Who cares!? He has a take-charge personality!"
I think the panels recharge a battery. Is the satellite always within line of sight of the sun?
Solar panels when illuminated by the sun, battery power while in the Earth's shadow.

To be low latency they need to be in a low orbit, so probably on battery power for a significant fraction of the time.
Exactly my point ;)
Lately he's been trying to maintain profile by lazily inciting feuds on twitter, and publishing tracts of Wikipedia articles on stats formatted in mathematica as deep research.

I like at least half his hot takes, but am turned off by the attention hunger implicit in his random trolling.

Can't tell if he does this to keep money flowing into universa which is otherwise a poorly run fund or what.
When I first moved to the SF bay area I didn't have AC in my apartment so I had to leave the windows open during the summer. After a year of leaving them open there was a thick coat of tire dust all along the windowsill since my window faced a road. :x
What about converting PDF to PostScript and back? It should keep most of the semantic information while removing the exploits.

As far as I can gleam from this report, they want to revitalize the old "bent pipe" model of satellite communication, where the sat only acts as a repeater . I am still very wary of it being feasible. While the track of BS->MS is feasible, albeit with a high transmission loss, i cannot fathom how they want to receive the <1W signal of the MS. Conventional way to pick up a signal below the noise level would be decorrelation, and while 3G/4G work on that principle, there would have to be additional information exchange between BS and Satellite.
Additionally, for that to work the SATs have to be in LEO, and as they describe them as "massive"(most probably the high-gain antennas), there then will be massive atmospheric drag, requiring either frequent reboosting or replacing.
The point is that, currently, people are "tracked down" by medical authorities and put in quarantine.

The AVICOT-APP concept is opposite: People would (should) like to know if they represents a danger to, say, their elderly parents, who may die if infected. Thus, there is no need for "the system" to be able to track or identify them at all. Only you, the end user, will ever know if you are in high risk.
I generally like the Drudge Report, but his headlines do seem like he’s been effected by the same temptations of cable and online news. It creates this effect where you visit more / watch more news. It makes it very difficult to understand reality.

I wish all this energy and attention could somehow be harnessed into testing 100x more people and making a vaccine. And for us regular people, just do what we can to be safe and go on with our lives.
Weird - I just experienced one of these as I was waking up about 20 minutes ago!

I say "weird" b/c it's not a regular thing, but I have experienced this a few other times, along with similar sudden full-body "spasms" while drifting to sleep. It's not usually alarming, just a strange feeling.
I try. Regrettably, my wife very much can stop thinking about sex. It's like a superpower.
The batteries are powered by solar panels. In either case the same arguments apply - space is notoriously low power.

Phones can't use directional antennas, otherwise you'd have to point them at radio towers. Using phased array antennas in which directionality is software controlled, there's a trade off between size of antenna and how much you can focus the beam - it wouldn't work in a phone (and would be too expensive anyway).
I'm a dad in Stockholm and currently in the first month of my parental leave which is expected to last at least more 6 months. My girlfriend just went back to work. Our daughter is 11 months old.
I worked 75% from the time she was 6 months old until a month ago when I went for a 100% parental. My employer pays me a bonus on top of the state money as a perk.

As far as I am concerned I can’t even imagine it being any other way. I understand how fortunate I am to be in Sweden. It truly is an amazing system.
Of course we do! Using blame/annotate every team member can get the idea who made the changes in question and why they did it. With 9 years old codebase of 400+kLOC (not counting blank lines and comments) this perk is invaluable.
I don’t install it system wide, just download a single binary into youka directory.
Measuring Feline Capacitance
I'm similar to OP in that I'll get excited about something but I don't usually get past the very intro before I get bored or frustrated and stop.

So I learn very little, and often restart the same things over and over. Eventually I give up and play computer games because they steer the focus and drip-feed novelty and reward compared to actually doing anything more productive.

I've had this before, combined with sleep paralysis. It sounds like a load rushing river combined with the sensation of falling, and I can't move. Was pretty scary the first time. If you don't fight sleep paralysis though, it's mostly just like lucid dreaming.
Not sure about the most serious issue, but by all appearances it is a very serious issue - https://en.wikipedia.org/wiki/Economic_impacts_of_climate_ch... suggests on the order of a few percentage of global GDP, which means it could easily be a multi-trillion dollar issue (as well as the indirect impacts that we're already seeing in terms of damage to ecosystems, human impact on health and livelihood, and political dysfunction). Even if you only assign a very minimal risk of 1% to all the scientific predictions being correct, you're still talking about an issue of the order of 10s of billions of dollars, so worth presumably some research.

It is hard to think of many issues that have a similar potential magnitude of impact. Most of these are political issues or wars - e.g. Brexit could cause an impact of a few percent of UK GDP by 2030, US-China trade war is perhaps of the order of 1-2% of US GDP impact on the US.

But - this doesn't really relate to the current article. The accepted approach to articles you don't think are relevant is to flag and hide, not to complain.
Germany is not testing nearly enough people.
There are lots of reports of people with legitimate concerns that did not find a way to get tested.
Northern italy is like 2 hours by car and each weekend thousands drive there for a short trip.
I love this. Reminds me of other articles about "flow" when you are so engaged you lose track of time.

This happens for me when solving hard problems. I can't stop thinking about it and work from the moment I wake up to when I go to bed. It looks like hard work, but it's energizing.
Sources? Data? Evidence? Studies? Citations please. This is a very strong claim!

And I'm saying this because my gut feeling sort of agrees with you, but so far MAPS' FDA approved studies doesn't seem indicate that there's this risk factor.

Who knows what will happen if it hits mainstream though. (As with any other therapies, at first everything is magical, because truly motivated people practice them, then it just becomes something done by certified professionals, then it just becomes a big section in a regular textbook.)

That said, there is very good chance that even if it's risky, it has at least the potential to do real work. ( https://slatestarcodex.com/2019/11/26/mental-mountains/ )
How do I remember to check this comment back without commenting myself?
We ended up having to do this during 9/11. I don't know if there are relatively more or fewer planes than then now, but I do remember that many/most airports had Jets parked on the runways and we're nearly all of their taxi- and runways for storage.
What you mean is either achieved with conventional high-gain antennas (Dishes, mostly) or with beamforming by either a passive, or in this case more likely, active phased array. TBH, I dont know of any commercial handsets doing so (albeit I am not that deep into the consumer market). On Base Stations, on the other hand, yes they are using this technology to improve reception and to limit inter-cell interference.
Almost everyday, often several times per day.

Changes made more than 10 years ago help to fix bugs still present today even if the codebase has changed a lot (they have commit messages, link to old tickets with more discussions ; sometimes, just the name of the committer tells a lot about what to expect from a change).

I've spent a lot of efforts when we started migrating from SVN to git to not lose this, knowing the pain of not having the history go far enough (some of our projects were already migrated from CVS to SVN a long time ago, and histories where lost then). Efforts have been more human than technical, BTW, since not everyone was aware of the value of the history — usually bugs in the oldest parts of the codebase get through only a handful of people who have been there for a long time, and other people tend to take for granted that we understand why something is the way it is.
For me, those side tracks are often closely related to a core goal, but still act as distractions that I have to avoid.

For example, my business is in the residential real estate industry. I think a lot about rent prices as a result. I have a pet theory that there's a bubble in the world of big building financing. I would love to spend weeks just digging into the data and trying to find out what's really going on, but that's not going to help my business succeed.

I resonate with what you said re: a sense of purpose. I think the way rental housing is done on the whole planet is a trainwreck, but a fixable one. I think it could improve the lives of millions of people if someone could shake off some dust and introduce some new ideas. It's huge and exciting.

I guess the fundamental problem is that there are many interesting and viable angles to solve the problem, but if you want to succeed, you really have to focus on a much smaller cohort of those angles (if not just one). So yeah, I don't think it's as simple as having a better sense of purpose unless your sense of purpose is extremely narrow in scope.
I've been having those for quite some time and was never able to pinpoint the reasons that could cause it. It's kind of fun when you get used to it.

I’m at Ground Zero in the US (King County, on the East side is Seattle), where about 10% of the reported cases are dead. I’m your parents’ age, in the 1.3% cohort.

Gotta admit, it’s scary. One death took place in the hospital where I had a checkup, on the day of the checkup.
