Seconding this! The placeholders are great but I was just curious what the best answers to the placeholders were.

Yes, if designers are component at all of these things:

> tests, observation, psychology and physiology

Is that not their job?

Yeah, sadly you're not guaranteed some of the things that are needed for this to work. I defo believe the story that it took Knuth a day to figure this out, although when you see the answer it's pretty easy to understand.

I just looked at this for 30 seconds, do you just XOR everything together? Then you could XOR it with all the numbers 1 to n again to get just the duplicate number, as every number would appear in the XOR twice except the duplicate number which would appear once.

Edit: I misread the problem :D I initially read it as every number appears once and one number appears twice, but alas it's not so simple :D

I think these kinds of people have just gotten more sophisticated. How much money did Sky Mavis raise? How much money did the Luna guy walk away with?

It doesn't sound like any of these regulations were a success, given Apple still has the monopoly power to extract 26% of the fees taken, and make the process so cumbersome that most developers would probably be better off staying on IAP.

Future regulators should take note, if you really want to make a positive impact you need to allow alternative app stores on the platform, and pre-empt some of Apple's counters.

  * Apple can't charge a fee for sales in an alternative app store
  * Alternative app store providers can choose whether or not to have app review (including a stricter app review process if that's what consumers want), and pick their own margins.
  * The same binary should be submissible to all app stores, including without needing to change signing certificate
  * It should be possible for developers to upload their apps to alternative app stores without going through apple developer certification (apps can be submitted using code signing derived from the alternative app store)
  * Apps downloaded from the alternative app store can use all libraries/sdks/apis generally available on the platform, with the exception of payments / advertising.

Is this unfair to Apple? I don't think so given they currently are triple dipping here:

  * Revenue from selling the device
  * Revenue from developer licensing
  * Revenue from their cut of IAP

Yes, we subscribe to a few CS/eng blogs with our company Slack and use the threads for discussions. Sadly https://blog.acolyer.org/ doesn't update any more but that was one of the favourites.

Really depends on the business. I'd argue that for forging product market fit, there's nothing better than a small team sharing a common space, feeding off each other's creative energy.

For later stage companies where you're optimizing something that's already mapped out, it's quite a different beast, but you're also probably hiring quite different people at quite a different scale.

+ open plan offices are hell

I've also found paying strangers on Monzo to be ridiculously easy, you both turn on bluetooth and go to "pay nearby" screen. You just ask them "Are you <full name>?" to verify, then send money.

Just a bit more info on free services - when we were starting out AWS were offering $10k credits a year for 2 years or $100k credits for one year. I believe we got access to this through one of our investors, but most VCs and incubator programs will be able to do this.

My first job was for a telecoms startup, this concept is called "glare" there. E.g. I go to touch the screen to make a call, but someone starts calling my while my finger is in motion so the UI changes and I press a button that I didn't mean to.

Here's to hoping this is just a starting point, might be that it's a lot easier to support these models.

There's other things they can do rather than just more patrols. At my university town in the UK the police would plant bait bikes and watch from afar, arresting thieves after they rode off. I know they caught some, because they caught someone from one of my lectures.

They kind of bootstrapped around this quite well. The first product was a better Google Maps app, which meant they got people's journey data. I wonder if the real problem they ran into was just that public transport in London is pretty excellent, so even with journey data plus the ton of data that TFL provide, it's pretty hard to actually run anything better.

I wonder how they're doing. Crunchbase https://www.crunchbase.com/organization/citymapper-limited/c... has a Series B for $40M back in 2016, and a crowdfunder for £6.7M in 2021. I can't imagine the pandemic was kind to them. It's a shame really, I remember they were fairly active in the London tech meetup scene around their B, usually quite enjoyable talks.

> I don't like GitHub's security screener dismissing this report because of the "social engineering" aspect.

Agreed.

I get where it comes from, npm isn't responsible for individual contributors getting social-engineered, but this is much deeper than that, and part of the flaw is with npm's support allowing the password reset to go through.

I believe the user you are replying to was also joking, given that many of Banks' ship names reference the g-word

Edit: if not that's even more amusing

I'm only talking analytics-quality data here, at the very least you would look at the major players and see where they are based. You would at least want to include anyone capable of doing setting up their own power plant specifically for mining, like these guys https://www.bbc.co.uk/news/av/technology-58020010

I skimmed this but it seems pretty heavy motivated reasoning.

> However, despite being extremely energy intensive, per unit power consumed, Bitcoin mining is probably one of the most environmentally friendly activities in the world. This is due to the unique flexibility with respect to where the power is required. This means miners often choose renewable power due to the low stable costs or miners are able to use otherwise wasted or stranded energy. This is a fact often claimed by Bitcoin proponents and it is probably true. Per unit power consumed Bitcoin is likely to be exceptionally environmentally friendly.

Ok, but what's actually happening? We can pontificate about how bitcoin mining could be hypothetically switched over to entirely renewable power because it is geography and time independent, but what's the cold hard reality?

What % of energy used in bitcoin mining is from coal or other fossil fuels?

What's the delta amount of fossil fuels burned compared to bitcoin not existing? How does that compare to other ways of sending money digitally?

Any defence of bitcoin on environmental grounds that dodges that question is flaky at best.

Good for them. The situation we’re in at the moment would be rejected as a sci-fi plot. We’re at a critical point in human history that will largely be defined by whether we as a species can save the environment, but a section of society are obsessed with speculating on a digital currency that corresponds to how much carbon you’ve released into the atmosphere for no reason other than to prove you own it.

This is interesting. I'm a founder of an app[1] that deals with this ballpark of issue, by providing (among other things) couples with sensate focus therapy, which is a form of sex therapy that has an extremely strong evidence base, and is a pretty standard go-to for libido issues.

We definitely have users that have experienced PSSD and have found our app helpful, and the underlying therapy techniques are proven.

"Personal carbon footprint" was an incredibly successful PR campaign by the biggest polluters to shift the responsibility onto individual consumers (who have much less ability to actually change anything). I'm glad to see the trend of pushing back this narrative. It's clear that the biggest polluters have profited immensly from pushing their externalities onto the rest of the world.

As much as I do like my personal choices and responsibilites, I don't even know why some things are available for me to buy. Isn't it kind of insane to think that I could walk into a supermarket and buy chocolate that was produced with slave labour? Why is that even an option? Similar for any product with an outsized negative environmental impact.

I'm not sure that the Democrats' path here is the way forward (I'm not American and don't want to try to understand if something like this is even legally possible), but expecting consumers to educate themselves about climate change in a meaningful way as an approach to preventing disaster is doomed from the start.

Relationships are hard, getting help shouldn't be.

At Blueheart we're re-inventing sex therapy: taking proven knowledge from academia, and making it accessible to millions through modern app design and psychology.

You'll work with really smart people, who've worked at places like Headspace, Google, and Saatchi & Saatchi, or who've studied at places like Cambridge, & Oxford. We've also published a bunch of research papers on sex & relationships.

Many of the team are in London and we have a small London office which we use for whiteboarding / pairing / workshops when it makes sense to, but many others are remote across Europe, and particularly for experienced engineers we are happy to support whatever mix of office/remote works for you, providing we can make time zones, legals and payroll work.

As someone who has trouble remembering which way round Type 1 and Type 2 decisions are defined, I have started calling them Bouba and Kiki decisions.

It doesn't help whatsoever but it does wind up my cofounder ;)

The 2015 MBP was definitely the peak. Normal USB ports, an HDMI port, the non-terrible keyboard, and no touch pad. I basically just want this with modern hardware (not just GPU/CPU/RAM etc, but webcam/mic/speakers have improved significantly, and I'd want a couple of USB-C ports).

I remember back in 2016 that some coworkers said that the new keyboard had ruined their life. I've not heard anything that strong about the touchbar but I don't know a single person who likes it and everyone seems to dislike it to some extent. Perhaps them ditching it will be the thing that gets me to check out silicon.

I've tried a bunch of online whiteboard tools to design stuff (where stuff could be system architecture, UI, a business process, whatever), and nothing beats a whiteboard + post-its. Maybe I'm doing it wrong, it's possible, and I'd love to have some great counter-examples. Until then, I think that teams that can meet up in person will, on average, win over those who can't.

Other days I just have long list of individual tasks that I want to get through without being distracted. On those days I'd love to just work from home, have space to dramatically crash on my bed to think about things, go for walks, etc.

With these two things combined I think the hybrid approach is probably going to win out, either where employees can use their own judgement when to WFH, or maybe having a system around particular days of the week.

This is really cool! Really excited to see what people will do with the JS support

Apple don't let us do any of that ourselves, so it's impossible to say that 30% is an appropriate fee for doing it. If they allowed competitor App Stores or direct downloads, and didn't ban us from even mentioning other ways to purchase a subscription (and other such anticompetitive practices), I would find this more convincing.

Nice idea! Planning to make money through affiliate links?

I have the same Dell Windows/Ubuntu setup. In case this helps you, I found that whilst plugging in a DisplayPort monitor into the USB-C port didn't work, I could get my 4k monitor to work either by going through a USB-C Dock made by Dell, or by using an Hdmi cable.

I also managed to get a 2015 MBP second-hand quite cheaply, and although the specs are a bit weaker it is a lot more pleasant to use.
