> The delivery apps are going to be hard to compete with. Restaurants have to get a base of people willing g to deliver for them.

This isn't a problem. DoorDash et al aren't particularly good to work for.

A local Pizza joint bootstrapped CarryOut Kings[1] off of their existing delivery staff after the pandemic started, and is now delivering for any business in town. They're making a killing, and I've got friends who work there who are making a lot more money than I was when I delivered from DoorDash. If I lost my clientele for my business I'd be driving for CarryOut Kings over the delivery apps without hesitation.

And even putting aside the numbers, there's a lot to be said for working for someone who has to look you in the eye if he screws you over.

At what point do we assert what we have known for years; that aggregted metadata is by its nature unethically privacy-invasive, and detrimental to human rights?
Agreed. When I read a business article that’s so far off base I have to take a moment to understand who wrote it. In this case —as is often seen with reality-challenged articles— the author has zero business experience and zero training in finance:

https://www.linkedin.com/in/matt-egan-7b75542b

He is a journalist who worked for Fox and now CNN and likely doesn’t know what he is talking about.

Before someone jumps on the apparent logical fallacy, let me point out that I started by saying his argument isn’t sound or valid, as the comment I am responding to correctly explains.
Nah, my point is that everyone dies no matter what, and most people die of disease in one form or another. These headlines are sensationalist, especially since they miss the point that most of the deaths are from people who are already sick to begin with (i.e., heart disease or obesity comorbidity rate is very high). Plus, in the US alone, around 100k people die every single month just from heart disease and cancer[1].

Yes, the virus has a high rate of transmission, thus we see a spike in deaths, but once it runs its course things will probably normalize and we can get on with our lives. Most people's immune system responds well to the virus.

So the NYTimes and friends publish meaningless statistics because it looks worse than it actually is and it helps them sell more ads and subscriptions by getting more clicks. If they reported the data within the context of reality, it wouldn't be as scary. I think the news is the main reason for the mass hysteria about this virus, meanwhile people continue to smoke cigarettes, drive cars, pollute, avoid exercise, and engage in a bunch of other activities that are far more likely to shorten their lifespan.

Anyway, I'm fine with burning karma because I think there's more harm from the economic effects of force people to stay home, which hurts the most vulnerable people the most. Rich people will be fine. I'll keep repeating myself because I'd rather try and convince people to get on with their lives than contribute to the sensationalist mania.

Preamble: I've been living almost exclusively on fast food deliveries since the start of the lockdown. Mostly because the only shop I'm able to get to easily has been an absolute nightmare, 30 minute queues and stuff.

I frequently order through takeaway.com, which is sort of centralized but most retaurants have their own drivers, but some seem to be shared across restaurants. I've had at least ten drivers ask me to order through the restaurant's own website in the future, buttering me me up with a 15% (!) discount. I can only take this to mean that takeaway.com is charging more than that as a fee, which seems like a lot.

There's probably a market for restaurant websites with an easy to use order management system and cheap payment integration.

If you have code that looks like this:

withTransaction(async session => {

await Promise.all([someOp(sesson),

someOtherOp(session)]);

});

Mongo may retry running it (calling the function again) if a "TransaientTransactionError" is raised (the transaction is retried from the client side rather than at the cluster).

However, when the driver calls your function again it doesn't invalidate the `session` object - so previous calls to the same function can make updates to the database.

Let's say `someOp` does something that causes the transaction to retry and `someOtherOp` is doing something non-mongo-related in the meantime (like pulling a value from redis). Now `someOtherOp` reached the mongo part of its code and it is executing it happily with the same session object (so operations succeed although they really shouldn't)

The point of transactions like you said is to perform multiple operations atomically and for them to happen "exactly once or not at all". With Mongo in practice it is very easy to get "Once and some leftovers from a previous attempt".

I have started one question-answer and link sharing site for followers of the Hindu religion.

https://hindumediawiki.com/

The design is inspired by Hackernews and initial users have liked it, now when it coming to traction, the only channel I have is twitter, where we have created a handle for the website and people are visiting the site through it. (the handle has crossed 6k+ followers in one month)

Now I am getting almost 600-1k pageviews every day without promoting actively but very few signups (~5-10) and very few submissions (~1-3).

We have inhouse users who keep posting interesting things on the site which make the site looks like it's active but how to gain the natural growth in terms of content (which will help us grow in SEO and will bring more visitors).

1) Can anyone give the idea of their own past experiments like this?

2) can you please give links of some posts on the web, where this issue is discussed?

3) what do you think can be next To Do steps?
In my defense, it wasn't clear that's what you were saying in your original comment. "Mood" has become a filler word at this point -- hence why I omitted it from the quote -- and can mean anything from the traditional meaning of "mood in the room" to "incredibly relatable/factual statement". How I originally understood your comment was that you were saying that you felt that most of the issues are in the past, but you still decided to migrate away from it.

> Even tools people joke about a lot like mysql never gave me this sort of data corruption.

That's about a decade out of date at this point. MySQL/InnoDB is the standard table engine and corruption is exceedingly rare. As of 2014, when I last directly worked on MySQL prod systems, there was no practical difference from PostgreSQL in terms of transactional guarantees. That includes APIs like JDBC which we used for billions of transactions.
You'll see down in the subthread that I essentially agree with what you wrote here. However, I still maintain the analogy to a distributed computing system is good and revealing. It's particularly the observation of the flow of forms and documents in and out of bureaucracy, as well as within it, that makes me think of it.

As explained below, I don't agree that it's a good idea to replace bureaucracy with code. However, I think the lessons our industry has learned in architecting software systems could inform designing efficient data and request flow within a bureaucracy. At the very least, it gives us language to talk about bureaucracies as systems.
I’m glad to see they locked it so rapidly once the pile-on began. I don’t agree with their position, but the comments over the past couple weeks have all the hallmarks of Internet mob behavior: “It’s been months since you made your decision and I’ve decided to stir up controversy about it again”. I’m not sure where this was posted about three weeks ago, but that led to the pile-on beginning here:

https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues...

And now we’re here having a dramatic outrage over it too. It’s not a great decision, but linking to this Reddit post was far less effective than linking to a blog post about this controversy would have been.

I wish we could have read a proper written story posted to HN about this, rather than being expected to sort through a haphazard pile of user comments without context. Is this only interesting because it’s disagreeable? Is the survey methodology the focus? Why did this matter to whoever posted it? Tell us a better story next time, OP.
Any time someone else makes money people on HN start a tirade about how evil capitalism is and how they should know exactly who is getting every penny they spend on every product or service.

This is the most inane thing I’ve read all year. The author speaks a lot about encryption, so I’m surprised she doesn’t seem to grasp how Mahadev’s protocol is essentially a cryptographic one. Would she have believed that public key cryptography was possible prior to its invention? Surprising that its conception essentially hinged on what most people would view as a curio from number theory. Mahadev’s result, in some respects, is the same. Except instead of prime factorization she’s leveraging trap door claw free functions. Arcane? Yes. Cryptographic? Certainly. ‘Encrypted’ in the author’s abuse of the word? Absolutely not.

But in one respect, she’s not wrong. There are examples where academics have published (yea, published) results that few other academics understand, believe, or trust. One occurred in 2012 when the Japanese mathematician Shinichi Mochizuki published a paper where he claimed proof of the ABC conjecture. It would seem it still hasn’t been accepted by the vast majority of number theorists. Another more recent example occurred when mathematician Michael Atiyah claimed to have solved the Riemann hypothesis in 2018, though I haven’t seen whether he stands by the original proof. These things do happen.

But Mahadev’s paper is not an example of this.
Yea Elsevier just finds whatever warm (free) body they can to edit.
What are the keyboards like on these things? My previous laptop (bought May 2014) was Clevo¹ (Horize W550SU-1), and its keyboard was OK but not great at the start, poor within one year (lost all crispness of feel) and close to unusable (spongy all over, activation issues in a few of the most commonly typed keys and especially the space key) within two.

Now I have a Surface Book, whose keyboard feels great, but it has two major problems: ① a modal Fn key (where tapping it, which happens all the time by accident, toggles its mode); and ② its matrix is awful: typing at full speed, it likes to drop and transpose letters in some words (e.g. “mouse” may come out as “moes” or “moeu”!) because it can’t handle even 3-key rollover properly.

For my next laptop I’d consider a Clevo build because they do tend to check the boxes nicely in most regards (e.g. https://www.metabox.com.au/store/b249/Metabox-Multimedia-Pho... looks great on paper: AU$2,000 for 15″ with 4K IPS and other good specs; touch/pen support is the only thing I would expect to miss), but unless I have reason to expect the keyboard is better than the one I experienced, I’m leery.

¹ At the time I was price-sensitive but wanted a decent screen, my first laptop having been a second-hand HP 6710b with a 1680×1050 screen; I was not willing to accept 1366×768. For a 1920×1080 IPS panel, the cheapest brand-name option was around AU$1,400, but a Clevo one at AU$1,000 had better specs all round save for using integrated graphics rather than a dedicated graphics card, which was plus for me as I didn’t need dedicated and would prefer to save the battery life, weight and bulk.

The best products happen at the intersection of an existing niche you are some level of expert in already and a technology that has not yet been adopted in that niche.

I've found one approach work very well with my mentees:

- Figure out which "special interest groups" you are part of beyond software engineering. That can be "aquarium owner", "coffee lover", "morning person", "diligent grandson" — the less technical, the better.

- Among these "niches", find the ones that could benefit from a transfer of technology, like (spitballing here) "teachers who work from home" (education niche) + "automated submission and pre-grading of homework" could work (digital document collection and rule-based checking logic), or "aquarium owner" + "nitrate cycle tracking IoT device" (hardware-enabled analytics) + "optimal light scheduling" (machine-learning-supported recommendation engine).

Do that for all the groups you're part of, and you will find lots of ideas that aren't just "scratch-your-own-itch". They are 'scratch-an-itch-you-understand-and-know-how-to-remedy'.
This has already been posted, so I'll paste my comment on that post:

I've been given this laptop at work, I use it with Ubuntu.

It's an amazing machine. Perfect under every aspect. Way better than the XPS13.

It's really, really remarkable. It's thin yet it has ALL the ports you might wish for in a modern laptop, 2xUSB type A, USB-c/Thunderbolt, HDMI, Ethernet, regular power plug, audio jack, sim card, micro-sd.

I'm glad it only has the intel integrated video card so I don't have to deal with proprietary drivers. The only downside is that the fingerprint reader isn't recognized and doesn't seem to be supported under gnu/linux.

Otherwise it would be 100% supported.

Wifi, bluetooth and camera all work out of the box. There's an IR camera, but I haven't tested it.

Had it had the trackpoint, I would have declared the TinkPad definitively dead and would have switched my personal laptop to this exact dell model (I currently use a ThinkPad T440 for personal stuff).

Mine came with a 4c/8t i7, 16 gb ram and a 512gb nvme disk.

It's really, really a remarkable small but capable machine.

Build an app for finding lost pets with facial recognition. Recognizing cats is the easiest thing for neural nets, yet I haven't seen it used for lost pets yet.

Basic idea, if my pet is lost, I open up your app, upload a few images of my cat and set a monetary reward. On the backend your neural net learns how that specific cat looks like, then other users of the app can snap pictures of random cats on the street and the app will tell them if that animal is lost or not. If someone snaps a picure of a lost cat, they'll get connected to the owner and the reward is transfered, the app can take a small cut of it.

Backups are useful only when all of the following are true:

* Done regularly in an automated fashion (if it’s manual, you will forget); use what comes with your OS or buy a good paid backup application

* Keeps older versions with a particular scheme (if you only sync, then your backups will pick up bit rot, and unintended deletions which are manual or through malware)

* Have multiple backups on different media and different locations (external drives break, cloud services lose data, your friend’s house may get burgled); you must have local copies (fast) and online copies (physically remote)

I have backups on external drives, a NAS and a cloud backup.
