I wrote a commercial memory allocator (long long gone) for pre MacOS 10 and tested it by writing a ton of memory bashing applications based on every perverse pattern I could think of in order to ensure it was fast, failure free and limited fragmentation. Of course from that era I didn't need to support multiple threads so that made it somewhat easier, but in building it (and studying others at the time) it was obvious that this is far from a solved science, and there were terrible design decisions in many common allocators at the time that made little sense.

It clear that some of these decisions still hang around today and that switching to a better allocator really can make a huge difference, especially given everything is multiple threads/cores today. But a lot of programmers never even look at memory usage or investigate alternatives. Even the JVM has a boatload of options on allocators for different usages; yet most Java programmers I know just go with the defaults.

Computers may be ridiculously fast and have enormous memory today and maybe you can live with the default; but it doesn't hurt to look, and might even save you money (pay less to AWS!) by reducing your need to allocate more or bigger servers.
I feel exactly the same way. Racket considers this one of it’s killer features so they should be plastering it all across the Internet.

Hey guys, wrote a piece about what wallstreetbets means for venture - it can be hacked.

tl;dr VC's should become more like social networks and let smaller ticket investors get involved. Collective intelligence and network effects can be leveraged for alpha.

I firmly believe the future of VC is collaborative and social. It will be driven by a blend of investors and creators. By “creator”, I mean founder, operator, expert, thinker, tinkerer, academic - really anyone smart who isn’t a VC right now, and probably doesn’t even angel invest because they don’t have enough money to write $25k cheques.

Done right, hacking VC will mean more investment from and into women, people from working class backgrounds and underrepresented minorities. It will mean more investment into overlooked companies in far flung corners of the earth. It will mean unlocking pockets of value that are currently sitting unleveraged and unloved, and it will mean improving the balance of wealth distribution.

The right solution will not be a two sided marketplace, it will be a social network dedicated to the purpose of investing.

MIT Energy Initiative study reports on the future of nuclear energy (2018)
I've mentioned at the beginning of this article, that we already have several systems running with tcmalloc. So using jemalloc would mean that we would need to bring new dependency. Tcmalloc solves fragmentation issue really well for us, we can get estimation of how much memory is 'lost' due to fragmentation. We saw that potential saving from let's say jemalloc, cannot be higher than 1-3% of memory use and decided it's not worth to bring new dependency for so little value.

Show HN: Glance Money - Privacy-focused Personal Finance App
Hey all,

Longtime Hackernews lurker, first time posting a project of my own here. I'm big into privacy, I am the Community Manager for Mozilla Thunderbird and before that I made the open source personal assistant Mycroft AI and worked at Linux computer seller System76.

When I went to use a personal finance app to aggregate my financial data (bank accounts, investment accounts, loans, etc) into one place - I just didn't feel comfortable with my data just sitting on someones server, especially when many of the apps I tried were startups with which I had little trust.

So I made Glance Money, it end-to-end encrypts your financial data on your device with a key generated there. It's also just awesome and allows you to quickly manage your finances "at a Glance". You can see balances, a transaction list, you can edit transactions, and even swipe through them via cards (Tinder style) via what I call the "Review Screen".

Yes, it uses Plaid to get your data, which means they have access to your data. Currently I don't have a way around that. Fortunately, they don't sell your data - but I have yet to solve for this piece of the equation.

What do you think HN? It's still very early days but would love for folks to try it and share what they think.

Why are historic fluctuations in global temperatures rarely mentioned in these articles? Actual historical figures are more trustworthy than future models based on multiple potentially false assumptions. Are we seeing a cultural desire to be “shocked” by the information we consume influence our research and funding of said researchers?

The following site shows a graph over the last 3000 years or so that puts current temperatures at a high point, but it is within the range of recent fluctuations in global temps. I have seen graphs that go much further back in history that demonstrate current temperatures are lower than average. Should we take drastic measures to fight natural fluctuations in temps? How much influence is due to nature vs human? Has anyone addressed this properly?

I've been looking into 12 / 18 / 24 month calls for Tesla, AMD, NVDA, AAPL and there is nothing cheap available anymore, even the really OTM stuff.

There was some stories about 12 / 24 month sub dollar OTM Tesla calls that printed between march and the split, but alas, no such things anymore. There are some deep ITM prices that sell for around the delta, but then might as well buy the shares.

Hey all - Spent the last several months in quarantine building this on the side. I play a lot of poker with friends and we wanted a platform that worked on multiple devices and was geared towards private home leagues. Additionally I was annoyed by the pay models of pay chips, pay per hour or a ton of annoying advertising.

Zoker is a simple subscription fee for an unlimited amount of leagues/games/players. The idea is to have as much game flexibility as possible, make it easy to share information (like Zoom and Venmo) and keep stats/leaderboards.

> Computers may be ridiculously fast and have enormous memory today and maybe you can live with the default

Often these hardware improvements exacerbate problems with memory management. For years the runtime of the default JVM garbage collector would blow up past 48 GB of allocations. Which was probably fine for 99% of software out there, but the day your honking great server blew past that... was a bad day all round.

It pays to know your allocators and garbage collectors inside and out for modern cloud scale computing.

I'm curious if anyone sees LibreOffice gaining any traction in a professional setting.

In my experience everyone uses MS Office or Google Docs, and LibreOffice still remains relegated to private individuals that don't happen to already have an Office license ... or Linux users.

I'm sure the situation is different in other parts of the world, where saving on license cost is more important.

It's a bit of a shame that eg governments aren't switching en masse.

But as a Linux user myself, I somehow tend to prefer using something like Google Docs in the (very rare) cases I need an office suite. Calc just isn't anywhere close to Excel, and the incompatabilities of Writer with Word make it problematic.

In my horrible opinion, you can have a fairly portable terminal application without using the abomination that is libncurses, just straight escape codes / control sequences.

Main reason is that most of current terminal emulators are actually xterm emulators: they support a good subset of xterm features. Also, the exceedingly strange console that was in Windows 95 is finally out. What quirks and differences are left, can easily be detected at runtime, no need for $TERM and terminfo/termcap
More basic, but open source. Obsidian has very interesting features for showing and creating connections between pages, archivy seems to take a more standard structural approach.
Links between pages are a planned feature, though.

One of the big features of archivy is how bookmarks work: If you bookmark a webpage, it gets converted to markdown and stored in your knowledge-base to prevent link-rot, which is an awesome feature.
I'm not sure Obsidian allows to archive pages this easily.

As I understand, some people seriously take issue with whatever is contained in that utterly useless "global" feed in Mastodon. This is basically all public posts that your instance receives. Some instances use ActivityPub relays to receive even more posts as by default an instance only receives the posts from users that have followers on said instance.
I keep looking at the changelog as the versions come and go and am generally disappointed that there's no concentrated effort to improve eye candy/defaults, especially in calc, but writer as well.

I use writer heavily at home, mostly for strict structured technical data and it serves my needs, though everything still looks awful in word. Given up on using calc though - still no tables, pivot tables are fugly and inintuitive - end up booting a VM 2-3 times a week to edit in excel for years now.

That said, I'm thankful for the contributors and everyone involved doing the best they can.

I thought I was very smart and did a DCF analysis of TSLA for myself. Looked into the assumptions, and convinced myself that even in the most bullish case, the revenues and profits generated by TSLA would not justify a valuation above 500B dollars.

I have now lost about the price of a TSLA Model S on paper, and still have not closed out my TSLA short. I should have just bought a TSLA instead of shorting TSLA.

The saddest part is, even if TSLA corrects I'll only make a few tens of thousands of dollars ... and I have in jeopardy hundreds of thousands.

One thing I realized from the vim course was people loved the interactivity part. (you can check out a video of the lesson authoring tool here[2]).

It's currently just a lot of work to build something that looks nice, setup stripe, setup hosting, setup the interactive components, setup remote code execution, etc. I'm abstracting that away so people can focus on content creation and marketing/selling the course instead.

He's missing optionality too. Most of things he picked have a non linear upside. On the one side you write internet articles about books being unprofitable and on the other you're Stephen King.

It’s unlimited because in the time he is holding cash there’s no limit to the amount the stock market could increase. If he sells a stock for $10, and then it goes from $10 to $10,000 he’ll only be able to buy back 1/1,000th of what he had. He lost $9,990.

It’s the same as writing call options. There’s defined upside and unlimited downside.

From a hardware POV, PC was more similar to S100 than it was to Apple II. The S100 bus was a dumb extension of the 8080 pins, the PC a dumb extension of the 8088 pins and the Apple II a dumb extension of the 6502 pins. The 6502 and 808x micros had very different timing cycles.

In comparison the fact that PC & Apple II used a motherboard architecture while S100 used a backplane architecture is very superficial. It was possible to buy S100 systems that used a motherboard architecture, it's essentially just hardwiring a connector. Here's one: http://www.s100computers.com/Hardware%20Folder/HeathZenith/M...

The other comparison point was in ecosystem: the S100 had a very rich ecosystem of vendors putting out systems and expansion cards, just like the PC Clone ecosystem.

Finally, the S100 and PC were open systems, whereas Apple was quite closed.

In 4 different ways I see PC as S100 v2.
It's unlimited opportunity loss. If you sell at say $100 and it goes to $1000 while you're in cash, you "lost" $900 vs your original position. However if you hold at $100 and buy a put for $2 that hedges you, you can still participate in the upside while limiting your downside. Also, downside risk has been historically undervalued (this may be changing though) which is why tail risk funds exist.
