Situations where I want users to go to a long URL but they need to type it, or tracking. I want to know how many times my CraigsList ad was viewed, easy I'll just use a short URL for the image and see how many times the image got loaded.
IMHO:

(1) Cheap, large scale storage of electric energy might be a big game changer.

(2) Without such storage, basically a country has to notice what their peak load is and assume that they have installed capacity that is reliable, e.g., independent of the weather, and meets this peak load.

(3) So, net, intermittent sources such as wind and solar don't much lower the capital expense needed. That is, the country still needs the same capacity to meet peak loads without the intermittent sources. So for this capacity they can use nuclear fission, coal, oil, natural gas, hydro, geo-thermal, and that's about it.

So, net, when power from intermittent sources is available, then get to save on the fuel cost of fission, coal, oil, and natural gas and accumulate some water behind hydro. So, e.g., a big fission or coal plant is still there, still with its capital expense and operating expense but is running at reduced power and, thus, saving on direct fuel costs.

At that point, I'm wondering if, really, just for the money part, if the intermittent sources are wanted on the grid even for free.

There is an issue about the intermittent sources: They are not very predictable and, thus, can cause some grid stability problems. E.g., IIRC, can't just change the power level of a fission or coal plant minute by minute to match the minute by minute fluctuation in the intermittent sources; so, can get some grid instability, and that is bad stuff for the whole grid and country.

One of the main use cases, and many vendors still do pitch this as a selling point - Analytics. You can put in custom tracking code (www.example.com/landingpage?utm_campaign=xyz&utm_source=abc) and share the same link (eg. a blog post) on different channels (facebook, email, youtube, etc) with different tracking parameters on the fly, so your analytics software can easily pick it up.

Trip data can contain extremely sensitive information.
I have tried so many apps to get my financial shit together, but I always end up returning to my Google Spreadsheet-based system. One worksheet for each pay period. No tracking of transactions. Just columns for who's owed what and how much I'll have left after everyone is paid.

Things aren't always perfect, but I have a groove and that's what matters.
I know. And there's really no difference between colocating mining hardware on wind turbines and just mining using the lower cost electricity which will be on the grid thanks to the turbines. Except the inconvenience of the colocating.

It is ingenuine on their part to not report how detailed the trip data they have is. Trip data could easily show Users' home/office locations, their daily travel patterns, their kid's daycare and whatnot. This kind of knowledge can be extremely dangerous if it falls into the wrong hands. Careem should be more straightforward about this and explain the consequences, rather than slyly gloss over the most dangerous part of the breach by mentioning only two effing words about it.

I've used similar phonetic algos in Excel to deduplicate CRM data during corporate acquisitions, it always seemed like the source data was hopelessly duplicated, but running a few of theses algos against the data, and then providing the 'best guesses' to the sales team to then do the final massaging of which accounts are truly duplicate or should be left alone.

Soundex is very simple but works well, calculating a strings Jaro–Winkler distance also helped.

> frequently have days of negative energy prices, where producers need to pay to feed energy into the greed because of overproduction of energy on windy/sunny days

This is one reason why I'm skeptical for home production of solar and wind for the ability to "feed back" into the grid while getting a credit on your account.

If the power company is also doing this, at scale, I find it really hard to believe that there's no reason the power company won't discredit/discount my rates being returned to the grid.

In which case, I'd rather have a battery installation and not rely on the power company at all.

Most service reps for solar disagree with me. Maybe because battery storage isn't super common/in their inventory?
I'd add Wave to that list.
51% attack is an issue that people have been concerned about for awhile. But an actor having 51% of the mining doesn't equal to poorly implemented centralized database. And a lot of ppl are keeping a look out for this issue so my guess is that even if one bad actor who happens to have 51%+ tries to hardfork, the rest of the community won't move.

There are efforts to deal with this issue. One example being the whole debate around moving from PoW to PoS and other systems.

Unfortunately, delusions of grandeur and a unicorn VC culture convince average young people into believing themselves to be power law founders with power law ideas. Thankfully that has changed a bit and it looks like the miracle men are moving into blockchain. In reality, billion dollar+ ideas are rare, and clever, delusional, and young people are a great fit for the helm.

When you're older, you have domain knowledge, leadership experience, and want to take linear risks, not "sacrifice one of the remaining chapters in my life for that chance".
For info sharing with suppliers etc, you have systems with trust. Calling each other's APIs with authentication credentials. Old solutions are much better than blockchains there.
I am a train fan, used to do it all the time with the family though Europe. Now I can not afford it anymore and flying is always cheaper. Not much faster with the obstacles, nor more confinient, but simply more economic.

How on earth that is possible remains one of the best kept secrets (to me). But I am sure there is a boat load of tax money involved.

Autonomous utility boats will have a significant role to play in monitoring and supplying the offshore wind industry.

These little boats can continuously monitor the foundations of offshore wind turbines for scour, and their larger brethren can quickly deliver supplies in a wide range of weather conditions -- without putting human engineers at risk.
AI and ML have different goals, which sometimes overlap. The goal of ML is to discover relationships in data that can only be (easily) observed by a machine. That usually serves as decision support data for a human decision maker or another more conventional algorithm. This is usually based on an entire data set at once. Accuracy and precision are valued over quickness and robustness.

AI is about substituting human decision makers or other conventional computer decision algorithms. AI is used for situational decision making. It needs to be quick (like the conventional algorithms) while also recognizing the nuance and multi-dimemaional nature of a lot of decisions. Robustness and quickness are often valued more than precision.

IOW the GP is only using ML for everything because it is a buzzword.

Yes, putting effort into finding a cheaper method is another option. It's the same with shopping for anything - you could go to 4 different shops and compare them, or you could just take the easy option. You can buy from John Lewis and get a 5 year no quibble guarentee, or you could save 10% and buy online, but have a hassle if it breaks.

Choice is a right pain, but it allows you to choose what's important

Edinburgh to Paris is a long trip - 1360 mile return. That's £600 for a car (HMRC give you 45p per mile, they wouldn't give you that if that was a grossly high amount), plus the cost of the ferry.

I can get a train leaving tomorrow and coming back on Saturday for £400 return, or 30p per mile. I can fly on the same days for £276 return, or 20p per mile. What is a fair price?

Transport is a low margin industry. The fact that some people can travel really cheaply is possible because others are willing to pay more for flexibility. This means those who want flexibility win (London to Edinburgh trains every half hour), and those that want cheap tickets win (12p/mile), and those willing to shop around win (even less than 12p/mile).

What would you change?
Does your bank send you messages on WhatsApp? Ofcourse not. They use SMS.

This whole initiative is about extending the base-protocol (SMS) which everyone is currently limited by.

While not universally good (carriers are still given too much power, w.r.t. billing, etc), it's main advantage over any other platform currently available is that this is a protocol-standard suggestion.

It's not a walled garden like iMessage or any of those other IM services (which is why no banks or similar use these services, but still use SMS).

This is something completely different, and I honestly wish more tech-startups would think in terms of standardized protocols instead of closed services.

Creating and developing standardized protocols is what once made the internet great and infinitely innovative. Recently the rise of closed services is what has caused this innovation-curve to almost completely drop down to zero.

Basically we need more protocol-development. EOT.

Maybe next time we can draft a standardized protocol which wont give or even include carriers. But for now this is a good start for creating a standard IM platform available for everyone to replace SMS.

Apple should have done this ages ago with iMessage, but didn't. Props to Google for actually putting in the effort this time around!
Thank you! I found those things incredibly annoying and useless, and was just about to dig through the source to figure out how to get rid of them.
I switched over the past month or so - started by using the vim plugin, and then eventually when ditched it and went with vim itself.

The scary thing for me, even after getting used to navigation, was the lack of it feeling like an IDE - autocomplete, compile on save, etc.

After installing some plugins - it's now wonderful and I enjoy it much more than VSCode.

There's a ton of little extra benefits you get from the switch besides the usual - for example, when you use a mouse, the time you spend navigating visually is kinda wasted. With a keyboard, that time is spent thinking about "what's the next parenthesis" or "what's inside these quotes" which turns idle time into something more useful like getting more familiar with the code.
Ah, you are correct that there is a missing element to the analogy, and this is it:

The woman lies dead in the murder case. When the rapper was pulled over, there was no case of a Ferrari stolen by a dark-skinned man. The police were not acting on a tip that the rapper was smuggling narcotics in his car. They stopped him for driving while black.

If we want to add the missing link, we then say that the police, knowing the statistics of men who assault and/or murder their partners, stop men at random in society and ask them to provide evidence that their partners are safe and sound.

When put that way, the case is even stronger against stopping the rapper on a "fishing expedition." If men were stopped at random to check whether they had assaulted their partners, nobody would be shouting that "SUSPECT != SENT TO JAIL."

Society would not stand for the notion that all men are suspect for the actions of a few, whether or not the statistics show that men are disproportionally more likely to kill their partners than women, or that the leading cause of violent death amongst women is men.

The very notion of all men being permanent suspects of a crime would rightly be considered abhorrent. And so it is here with people of colour.
Ask HN: From industry to teaching?
I've been working as a software engineer for some years now. I was offered a part time lecturer position at my alma mater for the Fall semester.

I'm super excited about the idea of teaching, but I've no idea how to be a good teacher (or how to teach for that matter).

Anyone around here has been on the same position? If so, Could please talk about what were your biggest challenges? Any advice?
I think the problem is the sheer number of dependencies, which introduces more chances for something to go wrong.
Ask HN: Should I directly compare my product to my competitors in my marketing?
Hi Guys, I run a reasonably successful SaaS product called Bx (https://usebx.com). Most of our users have joined us through word of mouth, or via link ups with various accountancy practices. So far we have done very little marketing - we basically just have a landing page and a video, neither of which are great. My competitors are the likes of Quickbooks, Sage and Xero and we would like to highlight where we are better than them. So I was wondering if it's considered unethical/bad practice to compare your features with your competitors directly on your landing page? Thanks for any advice/insight!
Thank you for Dinorwig. I did not know about this.
Market Research Using Conjoint Analysis in R
Is there a white paper or a clinical study to back up the claims on bee reader? I have read numerous studies claiming the exact opposite especially on a light projecting surface. I personally found the colour changing on each line to be extremely distracting and straining on my eyes. Furthermore, this seems like a bad joke for someone who is colour blind. Finally, VCs asking for ML are really asking how your technology fits in to the general future. With a script that reads line length and changes text between 3 colours, let’s be honest, I could have made beeReader when I was 10. Perhaps the VCs were initially wow’d by how profound you believed your product to be but then were underwhelmed by the tech (I’m guessing that’s why the individual page is burried). And if any publishers are in talks with you about using this in printed media (welcome to imaginary land) just keep nodding to what ever they say take their money and run.

> There are plenty of landlords who are losing money on their rental property.

Only until your current lease term expires, at which point your housing costs will unexpectedly rise (and sometimes quite dramatically). Unless you live in such an undesirable location that the landlord is desperate for any tenant, they aren't crazy enough to agree to a lease on which they'll lose money.
Wonderful, hacking often means dumping one data store due to sec problem with it (think 90s-SQL-injection).

I assume trip data was stored in the same system as emails - so both got hacked. Minor security considerations would put those in different systems and not store together.
So where's the innovation? If that's blockchain technology then Linux package managers, PGP, HTTPS and bittorent have been using "blockchain technology" for a long while now. I could've come up with this solution 10 years ago if you had asked me, and I'm really not that clever. Did IBM engineers really just discover public key cryptography?

The current blockchain craze is supposed to find its root in the Bitcoin whitepaper which is about a decentralized distributed trustless immutable ledger. If you remove any of these attributes you end up with something absolutely mundane that definitely doesn't warrant the ridiculous amount of hype, resources and money being poured into it. There are only a very small number of problems that can be solved with a decentralized distributed trustless immutable ledger. That's exactly the point of TFA.

I think this is a very important point to make because many cryptocurrency zealots ofter argue that "the blockchain technology is here to stay, ergo cryptocurrencies is here to stay". Except it turns out that the term became almost meaningless because anything sort of qualifies as a "blockchain" these days, including many centralized systems like IOTA or Ripple or systems that are de-facto centrally managed and mutable (like Ethereum).

If people realize that Blockchain is 90% hype, 9% old technology and 1% actual innovation then maybe they'll think twice about whether having a ~$400 billion market cap for cryptocurrencies is sustainable in the long term.
Are you sure the trip is over? ;)

But kidding aside, yes, what we're experience is lower-fidelity version of the outside world. First reference to that idea that I'm aware of is Plato's cave. Of course, that idea and Occam's razor together says that trips aren't deep insights, but merely differently distorted but still low-fidelity projections of the world around us.

I'm liking the thought of a brain as a time share, though. If nothing else, it makes for a rich subject for interesting stories. And a good metaphor for the existence of the subconscious (and heck, the limbic system)
i always enjoy reading these articles, because others like myself who have had their startups acquired at a young age are beating the stigma.

but i feel as though in this day of age there’s so many “companies” who claim to be “startups.” sure, they may have the experience, just not the capital.. and with that it completely changes everything.

anyways i’m 21 and had a “startup” (an app) acquired at 18. now back in school, i can understand the articles perspective. i’m only 21 and i feel like i only really have 10% of the knowledge, compared to someone who is 40 and who has so much more experience then me.
> 1. I have a hard time managing my bank account AND my main credit card. Mint seems to think me paying off my credit card bill is another expense, however Mint already tracked the CC charges so basically Mint thinks I run a massive loss every month (yes I've tried fixing this, multiple times)

Paying the credit card bill of $X from your bank account should be offset by the crediting of $X to your credit card.

Spend $100 on your credit card,
Pay $100 to your credit card from bank,
Credit card has +$100 credit

The only net spending here is the original $100. The line item of the $100 coming from your bank should not be counted as additional expense, since it should be offset by the line item credit on the credit card.

Fwiw, Mint seems to handle this fine for me.

I don't disagree entirely. I think there may be some ... I don't want to say completely 'new' benefit to blockchain in this respect, but as it's explored more, there may be some other benefits which go beyond current approaches to info sharing/trust.

I suspect it will end up being more like 'nosql' - appropriate as an adjunct tech to deal with specific use cases, vs a foundational mindset to build everything on top of. But... that's just my own half-coffeed-this-morning thoughts...
