People don’t realize you have unlimited loss potential on every stock you are not holding right now, and that’s why cash is not a great position. When you sell and wait for a dip, you are basically in a short position except you’re not borrowing stock.
> Yahoo! Would have online games, chat rooms, site recommendations and email all accessible from its landing page and it was a similar story for many of the other search engines as well. They considered themselves the homepage of the internet (and in many ways they were right).

Still a winning business model, because this line could easily describe Facebook.
Yeah, well, pfft. Not being on the market is an opportunity loss, sure. But it's not "unlimited".
Very inspiring work. Thanks for sharing.
Sorry that it made you feel that way. It is just the colleague who built the landing page thought it was a good idea to ask for stars there..

We install our own datacenter hardware. Hundreds of servers. Carrying. Mounting. Cabling. I'm no stranger to hard, manual work.

I feel tired, but I feel no pain. That's a different kind of being exhausted. Mental exhaustion cannot be compared with physical exhaustion. Both are hard, both are crippling, however one is not better than the other.

It's also very satisfying to install a new fleet and bring it up while drinking tea with muscle tingling all over your body.

Thank you.

Our company used Libreoffice for many years but we switched to Google a few years back and i could not be happier.

We are a development consultancy, the sales people mostly used MS Office before the switch to Google.
As an aside, I love the look and feel of this document. It is a beautiful read.
So when will all the politicians drown?
I used this resource as inspiration for when I had to rewrite the documentation for my JS library[1]. There's still a lot of work involved - particularly when it comes to finding the enthusiasm to write up another tutorial lesson or 'How Do I?' note but - overall - the documentation I have now is a lot easier to maintain and update as the library evolves.

How useful it is for others ... I don't know the answer to that one. But knowing the documentation satisfies my needs (it's a Big Library; I'm constantly forgetting small details about how to use it) is enough for me.

Key phrase: "future cash flows"

And it is actually future profits. Revenue moves all over the place, as do expenses. Toss in comparison to prevailing interest rates. You have 3 variables.

These are then in turn influenced by social desires, competitors, and regulation.

What is surprising to many people is companies desire to have more regulation as it reduces competition.

Social desires is why companies advertise.

Therefore if you have a long term contract to advertise on a TV show that now becomes the MOST popular show ever ....

And then of course there is the new regulation which will cost you a dollar per product, but will kill off any new startup as they do not have the resources to address it ...

Oh and the rain fall in Cuba has ruined the crop for a key component of your product driving your costs up, but your competitor gets the component from Chile ...
Yep, many FAANG employees got rich trading during lockdown.

> 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.

I find Calc to be quite complete and quite compatible with Excel files. I deal with way more Excel sheets than I would like to, but I can't remember the last time I ran into a problem with them.

Google Docs on the other hand is quite slow and lacks a lot of features and has the disadvantage of being browser based and a Google product.

I'm not a natural mathematician (emphatically not!) and pretty much every attempt I've made to wrap my head around Category Theory has foundered on an onslaught of formalism by paragraph 2.

To be clear, I'm not knoocking that: for those who can and do grok things from that sort of treatment, all power to your elbow (and no small amount of admiration).

But it's not how my brain works. I need an intuitive understanding first: exemplars, informal pictures, whatever. I can only start unscrambling the formalism once I have the intuition.

The author's introductory blog post is a great example [0]. It's without doubt the best "bootstrap" I've come across - where "best" means "most understanable to me". I really admire people who can take abstract/complex subject matters and lay them out in a clear and accessible way for the layperson. Tai-Danae Bradley definitely fits in that Category (dubious pun intended!).

yeah, my reaction is, wait, there's a product with "Libre" in the very name that is not actually open source, only the "Community" version is, is that what's going on? I thought the whole point of LibreOffice was to be open source, it's in the name! Is it actually "open core" or something?
Could you expand on the last paragraph? I have trouble following it
I like the part where he was talking about how much better web ads are than print because you can track revenue per ad dollar spent. He was about to say something, paused to find another term and said “marketer’s nirvana.” I wonder if he originally thought to say “marketer’s wet dream” and edited himself since he’s on video.

I like how he truly seems to be into the internet and chose books as a vehicle.

At any d&d table there’s usually 1-2 people who can bridge fantasy and reality and make them both better. Then there’s people who live in fantasy. And of course there’s mundies/normies/whatever who are in reality and would never spend hundreds of hours in make believe.

It does, and my own decision to pursue Linux (in the mid-1990s) was based in large part on seeing multiple cases of earlier proprietary tech knowledge (CPM, DOS, classic Mac, MVS TSO/ISPF, VMS, MS Windows) either be made obsolete or limited to specific hardware or system vendors.

By contrast, Unix, in its BSD and GNU variants, was vendow and hardware independent, and by the mid 1990s, Linux was pretty clearly its successor.

Editor / word-processing tools have been especially telling. I've used and often been expert at: DOS Edit, EDT and EVE (both VMS), MacWrite, Wordperfect, Wordstar, MS Word, AmiPro, Notepad, MS Write, Aplixware (an early Linux office suite), and multiple variants of Libreoffice (StarOffice, OpenOffice, NeoOffice, ...).

And then there's vi/vim, which I first cut my teeth on in the mid-1980s, and which I still use daily and learn new features and uses of all the time (some themselves new, often long-time capabilities). That's been an extraordinarily durable learning investment. (Emacs similarly so.)

Awk's another basic tool that's quite useful and ubiquitously available.

There have been hitches and inconsistencies: hardware changes invalidate old concepts (shutdown sequences as noted here), firewall, audio, and other subsystems have changed dramatically and multiple times. Physical vs. cloud server management is a very differrent head. Systemd is a major (and often disturbing) development.

Generally, though, the further you stay from GUI and vendor-specific tools, the more durable the knowledge. My preferred desktop environment is based on the 1980s NeXT and has remained almost wholly unchanged since the mid-1990s whilst GNOME and KDE underwent multiple revolutions and Xfce4 came into being. Windowmaker still does things none of the other three can touch, and my muscle-memory is well into its third decade.

As you get older, learning slows, but it's forgetting which becomes especially hard. Durable, incrementally-evolving tools minimise that pain remarkably.
That's why statecharts exist.
I've been a Product Owner and been responsible for the product strategy, feature roadmap, backlog refinement and management of external stakeholders, reporting up through product leadership.

I've also been in a company that had "Product Managers" and "Product Owners", where "Product Manager" was just a more senior Product Owner, and the "Product Owners" reported into the "Product Managers".

All I mean is that - it's different things in different organisations, and what one company calls Product Owner another company will call Product Manager. If someone takes a job title saying "Product Owner" and expects that to mean they will definitely be reporting up through technical leadership, in the real world I think they will be surprised to find that's quite often not true :)

This is great! How does it compare to blazegraph and how does it compare to redisgraph?

As far as I can tell, it's not for doing parallel graph analysis (i.e. GAS) on the GPU, is that right? (It's hard to tell, because I'm also seeing that this is designed to be used for GNNs.) But if I wanted to spawn lots of workers on a single machine, I could do that?
What to Do When a Nightmare Web Design Client Wants a Refund
If you're selling a product related to vim I think HN is probably one of the best places on the internet to advertise your product, don't you?

I imagine most HN readers fall in to two groups - those who are greybeards who already know a lot about vim, and those who are much more familiar with VSCode and don't care to learn vim. If I was advertising a vim course I'd target places on the internet where junior sysadmins or Linux devs hang out long before I'd hit HN.
You'll also get the people with original ideas and the people who want to change society.

The people who thought marijuana should be legal who were considered druggies, the people who thought gays should be allowed to be married despite society considering it an abomination at the time. The underground railroad type places that society doesn't condone.

In order to break dysfunctional social customs you have to be able to talk about them freely without censorship or social cooling.

And by throwing free speech forums away you're throwing the baby out with the bathwater.

So you're half right.
> I'm curious if anyone sees LibreOffice gaining any traction in a professional setting.

Here, also nope. There are GDocs users, and then MS Office users (there is a tendency that GDocs users here are using the office suite for its relative ease of use while MS Office users do tend to use the bits that are relevant to their needs (for example, Excel automation and advanced formatting found in Word which is good enough to not justify spending more in InDesign and similar applications).

We have trialled LibreOffice before, but the results were dismal: even though LibreOffice (to its advantage) approaches Microsoft compatibility, we still experienced some minor bugs (were reported and subsequently fixed) and missing features (in the sense that PowerBI and others were providing, plus real-time collaboration which Microsoft has a decent solution) means that even considering and removing training costs from the computation, it would not justify changing from Microsoft Office (or even GDocs) to LibreOffice for us. Google has eaten the basics and Microsoft has eaten the advanced users (and R/Py/Julia for even more advanced users), so to speak.
The value of a company or anything else is just based on supply and demand. "estimated future cash flows" just influence the demand and supply of the stock.

Doesn’t the existence of the website validate that Amazon considers the union to be favorable for workers and, therefore, unfavorable to them? Otherwise, why would Amazon care enough to create it? I doubt it was truly due to Amazon’s concern for the workers alone.
Uh, they completely botched the dosing in during the trial. Not just a little, but off by 50%. Then results weren't as expected (those on lower dose fared better) and they had no explanation.

That's not a "full trial which proved safety and efficacy".

What Makes a Killer Pitch Deck Presentation
A secondhand anecdote:

An acquaintance of mine used to be a professional options trader. A fairly successful one, too. He retired from the job in his early 30s.

After that, he tried doing a little options trading on his own behalf, for old times' sake. The look on his face as he recounted how that went down was a sight to see. I don't know exactly how much money he lost, or how quickly, but my take-away was, roughly, "Here is a person who, having first traded options with great success as a professional, and then traded them with great failure as an amateur, became more convinced than anyone that options trading is best left for the pros."

It would seem that there's a reason why Bloomberg terminals, broker-dealer licenses, exchange membership, a spot in the exchange's colo, and all that good stuff are such expensive commodities.
I don't understand why people are focused on rising sea levels. This is at best the 3rd most important consequences of global warming. In my list it is barely 5th, and the one whith the longer term.

* Food insecurities will be the first challenge, as it will come first probably and will have impact on democracy and will transform food import-dependant countries in powderkegs. US and Europe will be spared by this (southern Spain and Italy not so much, but still). Syria and Liban will be crushed.

* Wet-bulb temperature will become the second challenge by 2080, and 2060 if nothing is done by 2040. When Florida, South carolina and south cali will be hit by this, people might start consider moving, or living underground more than half the year. Europe will be spared by this as most projection say the Gulf stream will likely still work until the north pole ice melt, so 2150-2200.

* As the troposphere warms up and the stratosphere cool down, we will witness harsh meteorological events that will strain infrastructure all around the world.

* Ectothermics species will work at an higher level, their metabolism will be boosted and we will see pests working harder (and at higher latitudes). While endothermic species will disappear quietly. Same thing with mushrooms (that will worsen the 1st issue)

* Yes, sea levels will rise. It proably wont have any impact until 2080 for island nations (unless is contaminate their fresh water reserves).
One of the main reasons I use Amazon in France is their service.

I never ever had any issues, our biggest fight was about the 2€ they charged me once to send back a 100€ item. They gave up after the 2nd email.

I will pay 10% more for the Amazon price, for the peace of mind.
Another sign that it’s a puff piece is when it starts describing the persons involved: X grew up in place Y, etc etc.
It really depends on how you use them. My favourite strategy is to identify a stock I want to own, enter the market by writing a put at a price I want to own the stock at, and then if executed (and the stock price hasn't crashed), write covered calls at an inflated strike price. If the price goes down you can buy back your call and lock in your return, and write another call. I only do this on European style options to limit risk.

Assuming your stock selection criteria is sound, you can make money when the market is moving sideways or going up. When markets are down you wait it out. If your stock selection was sound, your stocks will recover when market sentiment becomes rational.

Having said this, you have to stick to the trading plan. You need to know when your trade assumptions are wrong and what to do prior to having to deal with a trade that goes against you.

That's the reason why it's "hard" and people loose money... it's not options per se, it's the personalities that trade them that are the problem.

Correlation is not causation.

I will readily admit that I don't have much context on the environment around or the legitimacy of his conviction, which is why my main point wasn't about that. I only added it as a response to that reply specifically asking about that aspect.

My main point remains "I think his conviction was already overturned, so there's no gesture left to for modern authorities to symbolically make".
> contaminate fresh water aquifers (see Florida now)

This is over-extraction.

No one will stop the over-extraction because they get to pass the buck to the biblically unstoppable Global Warming.

Personally I trend towards let the world burn, there's no way to stop this. The Global Warming believers cannot be pulled back, there's too many and they are to indoctrinated, they want Armageddon, it's an important part of their belief system.

They won't end the world. And it's sad what they will destroy, but concentrate on oneself over the damage Global Warming followers will cause and personally you will be better off. I unfortunately don't think there is a societal solution.
Heh. The results of Biden-ism starting to take their toll. Bet more big stores will vote to close down as well, maybe Long Beach to become the next "Detroit", or worse . . . .
Yes cryptocurrencies are one thing but look at the possibilities afforded with having a decentralized, distributed ledger in all areas of life. Having a source of truth in things like law or politics. This would be a fundamental shift for society as a whole not just finance.

Ask HN: How to Report to Supervisors/CEOs
Hey!

While I work fine and delegate well as a team leader and keep the team on track (and time), I still struggle to communicate achievements, relevant figures and more to my superior and the CEO.

I can easily deliver those when asked but I think for the growth of the team and myself it's important to communicate those without being explictly asked.

This still feels somewhat strange to me and it sometimes just gets lost in the daily business.

Now I wonder how I can learn to communicate better.

Maybe I should set a reminder bi-weekly for Friday afternoon to write a wrap-up of what happended in the two weeks.

But maybe there are better ways to communicate or report to those above me in the hirarchy.

Any tips, HN?

Thanks!
