This is true for you and other discerning readers. A lot of people just want the new Jack Reacher. I doubt there is enough volume or profitability here but who knows.

Interestingly, the only department to actually make money in B&N in the last few years, is the board game section. I think this is how they win. Being more of a general edutainment destination and focusing on kids stuff. 6 page kids picture books cost $7. Parents and grandparents will drop lots on "smart" toys and gifts for kids. I'd be all in on this, expanding with more play area and story times making it a fun place to visit. They already smartly dropped CDs as they have to ability to compete there except maybe to have new releases at the register as an impulse purchases but streaming mostly killed that.
> I sometimes think the story about high-efficiency urban living is myth. This is especially true when I think about the number of SUVs and trucks I see when I go to Boston, sigh.

The efficientcy is in the number of SUVs and Trucks that you don't see relative to the population. Even in a traffic jam of them you couldn't see an "equal" ammount of them because they wouldn't fit in the area in a per capita homogenized area. Well unless they were literally all stacked up.

> I also don't agree with Anki's pricing model. The app is free on Android[1] but $25 on iOS[2]. I think I heard (I don't have a source) that the developer's justification was that they needed to make money from the all the time and effort they spent creating Anki, plus hosting costs, etc - so why not do a cheaper price on both Android/iOS, or do a free-to-download app with a subscription model

People with money overwhelmingly buy iPhones. $25 is a pittance for anyone who can afford an iPhone. Anybody who uses Anki seriously gets far, far more value than $25 out of it. I used it for well over 200 hours before I stopped and I know I’ll go back to it again.

The Android version is not maintained by the developer of Anki. The iPhone app is. He chooses to charge for the iPhone app, which enables him to make a living making tens of thousands of people’s lives better.

If you don’t want to spend the price of two pizzas on an app that the modal user will use for over a hundred hours don’t.

Anki has two benefits: memorization and understanding. Memorization is what comes from going over the cards, which is what you allude to. Understanding comes from the process of creating the cards, where you think hard about the atoms of information in the text, and their interrelationships, and cast them into simple questions. Then memorization gives you a much deeper understanding than if you hadn't ankied the text.
I could see they are using three.js for a visual library, but I couldn't tell what they were using for audio. Maybe they are interacting with the web audio api directly, since they are only playing a single piece at a time. I didn't hear in fade in/out or more advanced functionality.
I work in a small team, we just install and configure everything without Docker, Kubernetes or anything else. Just install it like I would with any other software and then run it after configuration. When it's time to deploy we have a bash script that bundles the app and pushes it onto the server.

Almost too simple to work, but it does ;)
I don't think SwiftUI will be stable until another two years or so. Swift 1 and 2 were alpha and beta tests, Swift 3 code kind of was the final language where 4 and 5 were cleaning up the API's and syntax and incrementally improving the language. SwiftUI has the same roughness to it and I expect the same kind of breaking changes.

Good luck supporting this code until then!

But really nice. Once SwiftUI starts working properly it's true WYSIWYG in Xcode and exporting it from Figma really could help speeding up the front-end process.

It's like New Yorker profiles and longforms, there is a well established structure to these kind of articles. I can't find it anymore but one time I think I had followed a link on HN to a page explaining this type of writing, it's much more structured than I would have thought.
I had but I wouldn't even know where to start.
If you can help it then yes, for the sake of your metabolic health you should decrease the amount of time that you switch time zones.
I think one method would be to ensure you don't have the full key, i.e. you have some select friends, each that have part of the key (with some redundancy) - all unaware of one another and potentially all unaware that they even have part of the key.

Then you position your friends over multiple jurisdictions so that they cannot legally compel all of them to play along.
This is nonsense. There is no difference between the data that binocular cameras return and LIDAR, other than that LIDAR is more reliable and accurate. Your distinction between "depth planes" and "true 3d forms" is gobbledygook.
I'm running my GTX1080Ti for this, GPU-Z is showing me that the card is using 200W while running, let's be generous and say the entire computer uses 300W while running these computations. That means 7.2kW used per day, or 223kW used per month. At my current electricity price of £0.12/kWh, this is costing me £26 a month.

I have no idea who I could even donate this to so it would make any impact whatsoever. But I know for certain that there is literally zero chance they could rent a GTX1080Ti-equipped machine for £26/month anywhere in the world.
Is it me, or does this article basically romanticize abusing workers and glorifies running projects without a plan, just with a goal?

You jest, but he actually does it. Executing the right idea is the value, not the idea.

Interesting. I bought two games there this past Christmas. They had them- Scrabble, which I went there to get, and some board game based on the movie Jaws that I had never heard of. So I impulse-bought a board game there, and I'm not a board-game guy.

Considering PS3 only had 256MB of ram and was using all of it for computations or when running games, I think the chances were pretty slim.
Yeah basically LIDAR is better than vision for working out the 3D structure of the world. You can do it from vision, but it's really really hard.

We don't have a working driverless car with nice easy LIDAR data - it would be really silly to try and make one the hard way first, using only vision data (yes I know about Telsa).
Thanks. I think I'll combine our strategies. After they've already agreed to meet, I'll ask if they want to send over times and I'll give them my link.
Our local B&N does book readings for kids a couple times a week. I imagine most do. This drives a lot of kids & parents in. The kids play with a train & do arts & crafts afterwards. Everyone gets a coupon for Starbucks & they typically either have a treat or buy a book before they leave.

In a lot of ways B&N is like an additional public library where you can buy the books & games or just browse. I think that's what makes it different than Amazon. I also think that's their closer competition.

Limit Memory Allocation (if not necessary)

Multithreaded programs often do not scale because the heap is a bottleneck.

When multiple threads simultaneously allocate or deallocate memory from the allocator, the allocator will serialize them. Programs making intensive use of the allocator actually slow down as the number of processors increases.

Malloc (libc) is the worse memory allocation API to use.

Programs should avoid, if possible, allocating/deallocations memory too often and in particular whenever a packet is received.

In the Linux kernel there are available kernel/driver patches for recycling skbuff (kernel memory used to store incoming/outgoing packets).

Using PF_RING (into the driver) for copying packets from the NIC to the circular buffer without any memory allocation increases the capture performance (around 10%) and reduces congestion issues.

Design Evolution

Basic design of malloc() is to dynamically pre-allocate a pool of memory from the OS in which applications can then take smaller pieces from. malloc() is a standard API having a choice of different allocation algorithms and to mitigate the expensive OS system calls (typically done at program initialization time) during allocation of its system memory. The first memory allocation scheme started with a stack-based memory allocation.

Next came the dynamic-based memory allocation scheme where linked-list and bucket-heap mechanism are used to divide the private-heap using size class approach.

Soon, garbage collection algorithm introduced the initial backend of the memory allocation scheme. Frontend covers the usual malloc() API, et. al.

In 2006, a third pool was introduced (after operating system memory pool and library-based memory pool) called the “arena”. Arena is a jemalloc-term and is intended to deal with different memory types such as different-speed memory bank or NUMA-architecture, as well as memory tied to specific to each of the multiple CPU core or even CPU infinity.

Frontend Evolution
Frontend manages the memory being given to the application.

Within the frontend of the memory allocation system, the evolution went in the following order:

- link-list free space
- heap-bucket size classes (eliminating an object header)
- (Process) Owner encoding
- single core local allocation buffers (CLABs)
- Epoch encoding
- Large-size class memory block by direct mmap()
Hazard pointers (safe memory reclamation for lock-free objects) (M.M. Michael, 2004)
- Arena memory pool
- thread-specific local allocation buffers (TLABs)
- constant-time modulo synchronization (early return to OS pool, or FreeBSD madvise call)

Backend Evolution

Backend of the memory allocation system manages the empty, straggling, fragmented or no-longer used memory blocks back to the OS (thereby reducing RSS).

- Pool semantic: Remote f-list encoding, using Treiber stack), (R.K. Treiber,
1986)
- buddy algorithm
- binary buddy algorithm
- BIPOP Table (span-based allocator)(S. Schneider, 2006) aka local free list and
- remote free list
- segment queue (Quasi-linearizability, Y. Afek, 2010)
- multi-core distributed queue (A. Haas, 2013)
- k-FIFO queue (T.A. Henzinger, 2013)
Key word: "internal" -- these aren't on the internet, Traefik does ALPN, which means the LB itself has to be on the Internet. (Or something else that leaks the cert to the LB, but that doesn't sound any less complicated than using the DNS challenge.)

I used Anki's web interface from my phone for about 6 months before I bought the iOS app. Then about 4 years after using the app almost every day, I sent them another $25 donation. I got way more than $50 worth of value out of it over the 10 years that I used it.

It's as much of an article as one advocating a tool (or workflow) without exploring its weaknesses. In a way, both complement one another.
Well, when you pay your engineers 6-12 months of extra salary before you ship anything because they had to use Kubernetes-on-Highways to host this clever NoNoNoPleaseNoSQL DB hosted that some guy on Github wrote last week, hosted on ZeroNinesAsAService.com and with a new UI built in ThreeReact (the hot new React-based framework that implements an OpenGL interface that works on approximately 3% of devices in the wild right now, and approximately 0% of your target user base's devices), don't forget to account for that in the investor pitch and salary offers.

I mean, seriously, this is a startup killer. Our host wrote an essay a long time ago about beating standard companies stuck in boring old Java or C++ with your fast, agile Python code, but in 2020 it seems to me it's almost more important now to try to convince new startups to be a little more boring. Whatever your special sauce that you're bringing to market is, it isn't (with no disrespect to the relevant communities) that you're bringing in Rust or Nim or whatever for the first time ever, for Maximum Velocity. Just use Python, cloud technologies, and established databases. Win on solving your customer needs.

While by no means is everyone in the world using effective tech stacks well-chosen to meet the needs and without over-privileging "what everyone else is doing and what has always been done", enough people are now that it's probably not a competitive advantage anymore.

Honestly, you can beat most companies in just getting stuff out the door quickly.

I wonder how they handle differences in plans/knowledge/outlook between the 4 shifts. I can totally see the AM team working towards different quality standards or designs than the Evening team because they never talk to one another.
Facial recognition along with just cameras in general have historically struggled with the faces of non-caucasian individuals. This typically results from biases in training sets and in many cases cameras simply creating images with far more contrast for lighter skin tones.

Say No to Bloat
No one is saying that men’s unpaid work is worth nothing. The article is merely highlighting how much women’s work is worth.

And let’s be clear: if your mom was at home all day Monday to Friday while your dad was at the office and then they both did unpaid work on the weekend then your mom did a lot more unpaid work than your dad did. Nothing bad or damning about that, but it’s the reality of a lot of women’s lives (especially in previous generations). And what do you know, the article does cover that!

> We also compared the distribution of unpaid work across genders. India has the largest gap: Women there spend almost six hours a day managing the home; Indian men spend a paltry 52 minutes. The smallest divides are found in Sweden, Denmark and Norway, where social safety net programs provide care for children and older people.
No, sadly most Javascript APIs seem to use array-of-structs. It is definitely easier to write the code that way. I suspect most graphing libraries start out like that and then by the time they try to plot a heat map with a million points it is too late to fix.

Traditionally plotting libraries like Matlab and Matplotlib work on arrays of data.
In the last year or two I've decided B&N is done (caveat, sample size of one). Watching it through the years it has been clear that it was on a downward descent, but lately it looks like they've given up, again maybe only my location.

20-25 years ago, B&N was packed end to end with books. Books were spine out unless they were popular and trying to draw someone in. Coffee table books were limited to a rack or two of shelves near the front for impulse buys. Games likewise had a small section.

Along came the nook. It ate up a large section of the "fiction & literature" area. Obvious classics were still there, but deep cuts were few and far between. About this same time they moved to largely selling trade paperbacks in lieu of mass market paperbacks. So my option to buy a book that was in public domain started at $17.95. My experience at this point was that I would come in and look for something and it usually wouldn't be there. They would helpfully tell me that they could order it for me. The books they did have were the obvious popular ones -- exactly the ones that I knew about and could order from home. There was virtually no discovery.

But maybe that worked. Maybe not everyone is like me. At least they were trying.

Today it looks like they've given up. The ex-nook-section has tables with some books laying out. Most sections have trade paperbacks set up cover out (meaning fewer different books, on more prominent display), and the bottom shelf is empty is large parts of the store. Basically they just aren't restocking anything but the most liquid of books.

I still go every now and then because I have kids, but Half Price Books is far more enjoyable for the possibility of finding something that I'm not particularly looking for.

Why not? They have to have some kind of license to operate, right? Even if it's not labelled "driver's license". If their vehicles are going around running people over, revoke whatever license it is that they have until they get it fixed.
