Are bikes not allowed on trains or buses? That would be a challenge for a longer commute.
It's less fun when devtools just shows you the code for the whole thing. Maybe there's a source map that shouldn't be there?
Podcast Like the books the Cuckoo's Egg, Revolution in the Valley, and Hackers
Are there any podcasts out there either with the hosts or guests telling stories like the stories in the books The Cuckoo's Egg by Clifford Stoll, Revolution in the Valley by Andy Hertzfeld, and Hackers by Steven Levy?

I've read these books, and many others like them, but I thought it would be awesome to listen to a podcast where the characters from the stories are guests invited in to retell the stories, however I haven't had much luck finding such a podcast. There once was the Debug[1] podcast with Guy English and Rene Ritchie, and they had an awesome, and very long, "episode series" where they had Apple folks in to retell everything from how Safari to the iPhone was made, if I recall correctly. However the podcast has not been active since 2016. Once upon a blue moon I find a podcast that has a single episode of this kind, but without it being the focus of the podcast.

There are some podcasts like this in the hacking/dark web/cybersecurity genre of computing history - Darknet Dairies[2] and Malicious Life[3] come to mind - but I'm talking a bit broader in scope. I'd like to hear about how the first version of Unix was made, or Plan9, or Vim, or Emacs, or how this weird bug was discovered and fixed, and so on. Interesting stories told by interesting people from the history of computers.

Does anybody know of any podcasts like this?

Commercial real estate is going to be really interesting to watch. For a lot of mid-size companies, the building lease is 15% of your total operating expenses.

How Domino’s Stock Returned 4,595%
Yes, I know. That's the case for my friend, and I don't think anyone would suggest that her situation is horribly undemocratic. The parent comment's claim, as I understood it, is that this is horribly undemocratic because my renter friend is not directly a member of and represented by the HOA, as those rights are proxied through her landlord. My point is that I don't see how that differs from this proposed development: either you own, and are represented by the HOA-equivalent, or you rent, and are in the same position as any renter of a condo.
AI will generate new comments as you scroll... :)
great, yet another way to get tracked
Can confirm, have played a lot of video games and had purchased the Covid-19 related humble bundle.
This looks great. I love the focus on "party games".

What about adding poker or even making a dedicated poker app? I'm in a weekly, virtual poker game that is a mashup of different tools.

It seems this book is best if you read some small excerpts. I tried to read the whole book but I found the author to be a little too full of himself to make the book enjoyable.
This feels like trying to shove this into the opportunity available. There is no indication that cycling is better for the virus. If anything it might make things bad. You now have people sweating all over and trying to take showers and so touching everything.

I thought the page will talk about scientific advantages to cycling or something like that but it just rambles hope about cycling benefiting from this.
The Giphy integration that Facebook put into WhatsApp lets Giphy track who sends what GIFs to whom, so while the message is transmitted encrypted, a lot of context can be gleaned.

This acquisition makes a lot of sense.

Indeed. I call this the Serial Experiments Lain effect.
I think you can make the images a lot more appealing by adding some automated post-processing to them.

I don't know a lot about image processing algorithms but clicking "Auto" on google photos tweaks basic stuff like exposure, contrast, highlights, shadows, vibrance etc. so the image has a lot more "punch".
That's nuts. I had to replace some old Cisco media players that we used as digital schedule boards outside of ~20 classrooms. The Cisco players were quite old and only needed to load a webpage that pulled schedule info from elsewhere and displayed it in the proper format.

I decided to do this with RPi and went through several revisions as I learned/relearned a lot about Linux. The first version was built on full Raspbian and added a basic server listening on some port or another so I could remotely reboot the things by clicking links on a simple website I put together. That build would usually crap out after a few months and the Pis would stop booting fully from the Sandisk MicroSD cards.

Most recent rev was built from the "Lite" version of Raspbian as I was looking to stay slim and have less stuff to update/run in the background/cause issues with the basic operation of a device that only needed to boot, load Chromium, and open a webpage defined in the startup script.

Those have been a lot more stable (no more reimaging a card here and there every month or two) but they still occasionally crap out and a reimage is the only option (maybe once every 6-8 months). This is in an air conditioned building with stable power, wired LAN connection, and fast SD cards. I can't imagine they would be even this reliable running all the time in any sort of "hostile" environment or even using wireless networking.

I looked into network boot but didn't really have the time or resources to set it all up on the school's network.

Type of Hackers
Just launched last week--we're a dev shop that builds apps for other companies, but this is the first SaaS product we've grown in house to release in the wild.

Stack is Vue.js over Django deployed on Kubernetes. We built it to scratch our own itch to manage our standard procedures that got too big to handle with spreadsheets as our company grew.
Rust good, Go bad.
It would be nice if people who thought that came out and voted (skewing towards younger population). Obviously, a larger portion of the older population who do have their wealth tied up are not going to be a fan, and they tend to be the ones with the funds and votes to dictate political discourse.

> Which, I imagine, is why kerkeslager advocated not even informing people until conclusive data exists. But this strategy, of course, runs into the problem that Seneca identified long ago, "A lie can make it around the world before the truth can get its shoes on."

Well, the problem is that posting this sort of thing for a general audience isn't informing people. It's actually misleading people. I wouldn't call it a "lie" because the intent isn't to deceive, but it's certainly spreading untruth if what you communicate to people is what is being said in this thread.
Got a bit feel of Objective C. Related?
None of them. The Saturn 5 was discarded after launch.

I ride my bike 20-50 miles for fun. At 50 calories per mile, that definitely adds up.

Folks who exercise for aerobic reasons, you know, 20 minutes of brisk walking around the park, are getting benefits. But not weight-loss benefits. There's a 10:1 difference in possible exercise regimines. It all depends where you're at in that spectrum. Broad generalities are useless.
An additional problem is that Excel, the tool many people use to open CSV files, uses the computers regional settings for decimal separator and thousands separator. CSV files are used as an interchange format, so the format of the numbers in it does not depend on the region of that specific computer.

You can tell Excel to always use '.' as a decimal separator, but then it also uses it for presenting numbers to the user. It boggles my mind that software like Excel doesn't understand the difference between reading/formatting numbers for human use and reading/formatting numbers primarily meant for talking to other software.
The web of surveillance capitalism Giphy has in every integration is worth at least $400m to Facebook... Crazy!
>Russia took crimea without any issue.

You mean other than the crippling sanctions that were actually working until Trump took office? I think you fail to realize how close Putin was to the precipice on that one - when the oligarchs lose faith, it's tough to keep your hold on power.
check out kosmi.io - it has poker, card tables, snes/nes, quake and more!
Well, in US, that probably is because of several reasons:

1. Lack of central organization, it's easier to work with and pay a single private company or a contractor than hiring folks and working with open source projects that usually has no legal body, no billing, etc. Hiring and working with various companies to update, maintain, and so on with many projects isn't as easy as it sounds. (True, you could hire a single company to maintain a single distro for the whole gov't to use but is it cheaper than a private solution that 80% of the market already uses?).

2. Lobbyists, they'll explain it's cheaper to hire private companies to produce and cheaper maintenance over time especially since ^.

3. A share of citizens that doesn't believe in a bigger federal govt.

4. States want to do it their own ways instead of trusting the fed govt.

5. Distrust in govt in general on all fronts.
The Business Value of Brand Logo Design
While the phrasing irks me, I think I agree with the sentiment: "languages that value speed tend to expose more of the details, thus when presented with a performance problem, you have more options ready at your disposable". One of the biggest barriers for me personally as a long time user of high-level languages is going down into C internals and feeling like I can safely make changes. It also sucks if you don't want something that comes out of the box with Ruby (say you want a more memory efficient array than what Ruby gives you). C extensions allow you to add these things, but the knowledge is specialized and writing C extensions can feel like a black art due to a relative lack of resources on them

There are two other alternative interpretations that I think are untrue however:

* "languages that value speed give you tools that expose more of the details and thus help you avoid adding defects in the first place" which I disagree with because (1) the average programmer will not understand what most low-level options actually do and (2) exposing more options is like trying to program with ones and zeros - at some point low-level abstractions don't scale well in a constantly evolving project

* "languages that value speed generally have fewer abstractions and thus make it easier to find bugs because there is less abstraction" which I think is untrue in projects of meaningful size. Macros are very common to find in languages like C and arguably as complex as metaprogramming in Ruby. Additionally Java is considered a relatively fast language and Java projects often have lots of abstraction
Extremely cool idea. Generative illustration for the masses. Where can I follow your progress?
Another example would be Dropbox which quite recently published this great blog article about "Rewriting the heart of our sync engine" in Rust [1].

This is lacking some very critical safety systems such as breakbeam detection (someone walks into the path of a closing door), endstops (the system unexpectedly travels to the end of the track), torque/motor stall monitoring (aka crushing someone to death), and door speed monitor (the door starts moving faster than the motors are moving it)

GOP Official Says Fraud Warnings Hamper Vote-by-Mail Push
Really love this paragraph on the Shuttle Training Aircraft wikipedia page.

To match the descent rate and drag profile of the real Shuttle at 37,000 feet (11,300 m), the main landing gear of the C-11A was lowered (the nose gear stayed retracted due to wind load constraints) and engine thrust was reversed. Its flaps could deflect upwards to decrease lift as well as downwards to increase lift.

> but Rust's Drop makes the same mistakes as C++: destruction needs to be for consuming data, not borrowing it and mutating it.

but Rust's drop isn't for that purpose. It's not for the actual cleanup of the struct and its children it is for additional cleanup before the children are deleted. So it has to be mutable. The compiler synthesizes the "delete children" code.

(I don't understand your point about drop<T>)
Well, "90% of user time on devices is in native apps, 10% web" does paint a rather different picture than "70% of user time is in social media and messaging apps, 10% media apps like Netflix or Spotify, 5% mobile games, 5% all other apps including all the built-in ones other than the browser, 10% web" if you're not in social media, media, or games and trying to decide whether to go web or native.
GA pilot here. I'll send this to my airline buddies. Really useful.
Congrats Alex Chung! Met him a couple times in NYC and he was gracious and kind. I remember him mentioning that Giphy is the largest search engine behind google or so, which makes sense as everyone's searching for cool gifs in chat whenever they can. :)
I was surprised it it carried this kind of valuation too, but I think this is a matter of finding the right buyer. This isn't about revenue, it's another way for Facebook to harvest metrics, this time across competing products.
Nah not snarky.

The difference is mostly that Facebook is a company creating restrictions for speech on their platform based on the views of employees and shareholders of the company on what speech should be acceptable on their platform. Rules of the road are determined by governments and all people have stake in the process.

For most publishers I don't mind them having their own rules on what speech they would publish because there are other publishers you can go to, but Facebook has almost a monopoly on social media. And because it's free for anyone to sign up it's almost impossible to compete with their network. If you want to post or publish social media content and have a lot of people view it you basically have to use Facebook's network. So you have to obey Facebook's rules.

It'd be like if a road company owned 90% of America's road and had rules you had to follow in order to drive on them. Sure there could be existing government rules of the road, but they wouldn't really matter because you have to follow the road companies rules on 90% of all roads.

It's fine to have restrictions on freedom of speech. We have them already. You can't lie under oath, you can't make death threats, you can't yell fire in a crowded room, etc. Now because of Facebook's monopoly they get to choose what speech is acceptable and what isn't at least for most social media. We don't really have any insight into what choices were made and why they were made either. I would rather have governments and their people decide this in courts and legal system. We at least we deserve more transparency into how Facebook chooses to filter and select content for people to view.
Yes - those were the exact technologies I had in mind when reading that paragraph. We've been pre-fetching/loading HTML in place for ages! If all you need is faster/less jarring transitions between static pages, it's incredible to me that anyone would immediately reach for an SPA.

I'd argue it's not just lockdown. This has been an epic release year: Animal Crossing, Half Life Alyx, Doom Eternal, Gears Tactics, Valorent, Sea of Thieves. And on and on. Paper Mario: Origami King trailer looks like so much fun there is no reason to leave the house this summer ;)

fread is amazing. Whenever I look at the docs and see all the options for dealing with nested lists (like the within-column-seperator) I always pray never to have need of such a thing.
Only folding bikes are allowed on trains or buses, hence the local development of the Brompton folding bike.

In the Netherlands, it's not uncommon to have a cheap bike at both ends of a rail commute.
If some of the data are outliers, they arguably should be removed.
Any good alternatives to GIPHY?
I've bought several games for the Switch for my kids, including Animal Crossings. I don't understand it, but anything to keep them quiet for an hour (or three).

One question I have is, is this revenue rate sustainable or it is an unnatural pump that will die out in a couple of years? Once people can go outside without fear I'm thinking that it won't be a long term investment.

Makes me wonder whether you could use trends in use by employees at a large company to do some trading. If their gifs turn negative in advance of an earnings report, that’s probably not a good sign.
Importantly, tabs aren’t usually inserted into fields by Excel users. With Power BI, exporting TSV is a little easier for non-dev Excel power users, too.
The other interesting thing about this one, is that they dont even attempt to license content do they? They dont have any content costs?

Theres been this fake (steal) it till you make it, wild west approach to growth. Youtube, Buzzfeed, Imgur. You just host anybodys content regardless of if the poster is the owner, and once you get to scale, then you handle copyright and creating your own content so you arent as dependent on external creators.

But in Giphys case, they never have to take the extra step. Because they are so short, they are much more likely to pass fair use, and they can just host anybodys anything, barring some illegal fringes, without having to pay for the rights.

Both are extremely valuable.
Giphy data would include a wider user-base, but Onavo has much deeper data (all of someone's mobile data traffic, which would include seeing what someone is searching on Giphy and in which app)
You also have to have somewhere to put the bike while not in use. Bike theft in London (before social distancing at least) was common.
X- prefixes in for non standard headers are deprecated because too many X- headers eventually became standards.

It was never level-headed or intellectual.
You can seriously get small run chips made on 7nm in the US? I just don't believe it.
Also most new cars have options for HEPA filters. Filter MFGs do build HEPA filters for cars that originally didn’t.

On the other hand people could wear a full face mask with good screw on filters too.
Haha, its as if they took the legendary Adobe greentext story literally and took the effort to automatically update the entire beast constantly! For anyone not familiar with the great story: https://imgur.com/gallery/iJD8f
And worth noting React's implemention of vdom is at odds with smooth page transitions, since unmounting components are immediately removed from the DOM.
Hopefully it will be a huge moment, but without safe bike infrastructure (of which car-free or local-car-access-only areas are the best type) the traffic that comes roaring back will scare many new cyclists away.

The city's failure to plan is resulting in many people buying cars — even though it is physically impossible for everyone in central neighborhoods to buy cars.
Jane street isn't in the HFT business, it's more like day trading.
The bogus Adjusted EBITDA metrics popular with financially unhealthy startups and others really does need to stop.

In most cases these metrics may as well just say “Hey, if for a moment you ignore all the things about our business model that make it unsustainable our finances look quite good! Ain’t that cool.”

Of course the creative accounting that goes into these things tries to say they’re just “one time” expenses and other factors that justify ignoring these costs but of course most companies that play these games seem to have tons of “one time expenses” every quarter so...
> When I tap on a link on Tom's JS-free website, the browser first waits to confirm that it was a tap and not a brush/swipe, then makes a request, and then we have to wait for the response. With a framework-authored site with client-side routing, we can start to do more interesting things. We can make informed guesses based on analytics about which things the user is likely to interact with and preload the logic and data for them. We can kick off requests as soon as the user first touches (or hovers) the link instead of waiting for confirmation of a tap — worst case scenario, we've loaded some stuff that will be useful later if they do tap on it.

How many sites actually do this? And how much additional bandwidth (and battery life for mobile devices) does doing this consume?

> We can provide better visual feedback that loading is taking place and a transition is about to occur. And we don't need to load the entire contents of the page — often, we can make do with a small bit of JSON because we already have the JavaScript for the page.

In my experience sites that do this are almost universally slower and less responsive than sites that just use normal links. Maybe that's just confirmation bias and I just don't notice it as much on sites that do it well, but a particularly egregious example of this is Reddit's current mobile site vs their old i.reddit.com mobile site (which I use exclusively (despite it missing a number of newer features and having a lot of minor bugs the newer site doesn't) because it's way way faster).
