Ask HN: Looking for a web app for my organization. Or should I build my own?
I work for a school and we are wanting to transition to a new way of deciding which courses each instructor teaches.

Previously, the process was not very clear and there was one Excel document where everyone added their preferences for the courses they wanted to teach.

The new process involves the instructors having their own file or "portal" where they can go in, choose from a list of courses , choose their hours and submit them for approval. We'd also like it so each submittal by an instructor updates a main overview so that everyone can see what courses each instructor has picked.

I've been doing some web dev side projects for a few months now and I proposed I'd make a web app to do just that. I've got a bunch of it finished and it'll probably take me a few more months to get it polished.

This is a great opportunity for me to show my software skills to the school and also add this as a good side project for my resume in the future. I'm just wondering though if there are websites like what I described that would work as well?

Other people have answered the question quite well, but I just want to point out the Bitcoin FAQ [1], which is pretty well written. It is good to read the entire faq to get an understanding of not just bitcoin, but blockchain in general.

Here they are. [0] The FTC is perfectly aware that there are edge cases, but they refuse to define them or provide anything but the vaguest possible "I know it when I see it" criteria.

The point wasn't about startup time. The point s/he was making was that complexity can be a good thing in certain cases.

No one would ever expect or claim that a JEE application would have a fast startup time. That's not the level of complexity JEE is trying to optimize for.

Bitcoin's block reward has two components: block subsidy + miner fees.

Over time, most bitcoiners foresee the transaction volume and demand rising, such that miner fees will compensate for the reduction in block subsidy.

So once we get to the end of new supply around 2140, the system will sustain from ongoing transaction fees.

> Go ahead and let Youtube itself stay as a kid-unfriendly, algorithmically moderated wild west with hidden bombs of objectionable content spread around.

That's exactly what the FTC fuss was about, though. It's easy to say that until a parent gives their kid access to it and suddenly YouTube is advertising and recommending stuff to a child, which the law doesn't provide a safe harbor from (not for the content uploaders, either, which is going to cause a lot of problems). The FTC guidance was to identify kids instead by the content they were accessing. Hence Google's complaint: https://youtube-creators.googleblog.com/2019/12/our-comment-...

i think they're in some odd holding pattern on their downward spiral, where there isn't enough capital for changing the business or even purchasing new product, but there isn't enough business potential for new investment either.

perhaps they are keeping everything open as shells to try and shop some deal to potential investors as revitalizing a once great brand.

someone up high has some really good and specific reasons for keeping most of the stores barely open and operational.

if there were responsible people at the helm they would shutter nearly all the locations immediately.

they probably have a few dozen months of funding left at this pace, no idea what they're holding out for, they seem to be just delaying the inevitable.

Consider yourself. Consider a galaxy N million lightyears away that is moving away from you at high speed...

Or is it really? What if it's staying perfectly still, and YOU'RE the one moving?

... How could you even tell?

The principle of Relativity is that you cannot tell any difference, for the laws of physics are the same whether you are moving or the galaxy is moving. The theory of Special Relativity describes which mathematical transformations you need to go from one description to the other (in the absence of gravity, which is a General Relativity concern). Philosophically, the way of unifying these involves mixing up Space and Time, in which various observers cannot agree on a single version of things like speeds and time and energy levels, into a unified Spacetime, which they all can agree on.

"Changing your reference frame" simply means picking something different that you consider to be at rest.

Exchanges trade both in Bitcoin and BitcoinCash, and I've just learned from the paper that they form a tree with a common origin. Does it mean that if I owned Bitcoin before the Bitcoin-BitcoinCash split, I can now spend it on both chains?

4K is too pixels if the screen is large enough. I had a Hitachi 28” 4K before I upgraded to an iMac 27” 5k. The text on the hitachi looked like crap, you could see the pixel corners and sub pixel anti aliasing coloring bleed through 10, 12, and larger fonts (that is on Windows, on a Mac you would see lots of blurriness via font smoothing).

Aesthetics matter, for a few hundred dollars more, it feels like I’m almost looking at paper (if it weren’t for the backlighting).
So, imagine the box is filled with hydrogen gas. The space inside the box gets bigger. But protons don't, they're little packets of quarks that hold each other very powerfully. You'd have to expand space very, very, very fast to rip those quarks apart from each other, and once you did, you would have a bunch of bare quarks, not hydrogen. The quarks aren't getting bigger, since they appear to be indivisible and essentially pointlike, and even if they were made of something smaller, those things will hold tight to each other, too. A nice gentle expansion will just expand the space in between the protons.

This scales up to forces in between atoms, molecules, and bits of matter. It's only at the very large scales (larger than galaxies) that all the forces that are holding the stuff together starts getting overwhelmed by the expansion of space and it starts to pull things apart. The expansion is so gentle that even relatively weak gravity can hold galaxy clusters together even as space grows.

In other words: space gets bigger, but matter doesn't. It more or less stays the same size.

I'm always surprised that the computer games industry hasn't latched onto speech synthesis. Modern speech generation coupled with some sort of emotional + accent markup and a library of base voices would allow going from script writer to voice over, without the time and expense of traditional approaches and often poor results. You could even go procedural, dynamically generating speech. The main character can finally get a name and stop being a silent protagonist. Mods & DLC. Include novels' worth of content without the immersion reduction of text boxes.

MLM has a specific definition which this doesn't meet. MLMs are businesses where the majority of your earnings come from the recruitment of new members into your downline rather than sale of a product. 7-Eleven doesn't offer referral bonuses for bringing a new member that are based on a percentage of that person's sales.
In the US— It’s a lot cheaper for the franchisee to start than financing his own store. They also pay 50% of gross revenue and the store owners sometimes steal or manipulate the numbers/inventory. Internal theft and CC skimmers on outside gas pumps seems like a huge problem but I don’t know the exact numbers. Sometimes stores get shut down by corporate.

"...replicating a structure (through organizational or version forking) does not completely address the hierarchy of the structure itself. While it certainly gives others a voice and accounts for fragmentation in the community, power is not flattened among all participants. Quite clearly, senatorial governance is not a direct democracy but a representative one where certain actors (Lead Developers, mining pool operators, software companies) are raised into positions of power by grouping individuals (programmers, miners, users) through their obligatory passage points. This is not necessarily a negative revelation for algorithmic decentralization via (proof-of-work) blockchains but it is important not to assume all stakeholders of their protocols are made equal. The cost of collective action is hierarchy" (481)

The article is behind a paywall, but it's essentially a revisionist account of the block size debate of 2017.

This account seems pretty biased to me. For example, it not only gives short shrift to the user activated soft fork (USAF), but gets the basic facts wrong (page 15):

> User activated soft forks require a large amount of coordination, particularly from industry. ...

This is absurd. UASF was supported by far fewer companies than those supporting Segwit2x.

A UASF is a declaration that nodes controlled by a group of users will reject generated blocks failing to conform to certain specifications. In the case of the 2017 incident, the specification was that the block must signal support for segwit, thus ensuring its activation.

> ... The cohesive demand for a node-initiated upgrade of network rules gathers momentum around Bitcoin meet-up groups, forums, blog posts, social networks, conferences and company board rooms. With regard to SegWit, this momentum led to the ‘New York Agreement’ in 2017.

The New York Agreement led to the ill-fated and incompetently executed Segwit2x proposal, not the UASF. The author could have discussed that initiative in detail but didn't. In short, the (single) developer was incompetent and the update didn't even activate properly.
Yes, they share a blockchain history until a certain point. If your Bitcoins were sent in a transaction belonging to a block prior to the split, you own both BCash and Bitcoin.
Just by doing a few examples and thinking through it a little I think there is also another way to do this in binary with bit shifting using the same principles as the modulo 3 trick. It uses the fact that a bit when it is on modulo three alternates between 1 and 2. Maybe you could then 'unzip' the binary string and then use the string replacement strategy in two alternate ways depending on if it's one of the odd bits or even bits.

EDIT: hmm, unzip is probably the wrong term here.

> I wonder if jobs will also move in this direction.

They already have, where there is any commitment at all; that's what formal probationary periods, earned tenure, and temp/contract-to-hire arrangements are.

Of course, much work has moved past even the idea of commitment on either side.

> I suspect the main obstacle is that it's hard for a salary to be gradual

It's not hard at all, plenty of jobs that are paid salary at the nearest approximation of a committed level can be acquired after a temp/contract-to-hire period which is paid hourly based on hours worked, without guaranteed hours and at a total rate that, even of full time hours are available, is less than post-hire salary+benefits.

So if he paid $32M for the land and is arguing the government is destroying $30M of value by making a public beach (by law), well, public then he's arguing the property after the fact is worth $2M.

So he should take $2M for it right? Or he'd have no object to the State giving him $32M and simply taking the whole thing, right?

I'd be somewhat OK with these inflated property values estimates with eminent domain if the owner was forced to take $X-$Y for the remainder from any buyer.
There's a strong case for firms to publish more and higher quality data now the web makes it easy. Forget sattelite images use carpark stats from entry and exit and so on. Many of these equity analysts will do your job of analysing the data for you giving you a bigger lead on a developing problem or strategy failure allowing for sooner correction. On the flip side, earlier notice of strategy success for quicker ramp up decisions.

"Yes but we do more sophisticated data analysis anyway" - firstly, I call BS on that CEO & management career self-marketing and secondly, if I'm wrong and it's already being done at an excellent level there is nothing to fear putting it out there - you can spank analysts doing a shoddy job with hard analysis scotching undeserved "impression, zeitgeist and rumour" based negative market sentiment.

Of course every board of directors should have an IT committee and a data committee to go with the audit committee with a similarly highly qualified chair of those comittees. It's basically unthinkable not to have a very qualified accountant on the board. Should be the same for IT and Data - although IBM Global Services, Accenture, Oracle etc etc will campaign heavily against having people who know what they're doing on the board!

Chair of the data committee would be a crucial figure in earnings calls and so on - they better know their stats!
