ndespres··on What Happened to Lee
One idea mentioned in the article that I've seen elsewhere is this:

"The gist, then, is that someone is “himself” because countless mental artifacts stay firm from one day to the next, anchoring that person's character over time."

I have read reports that latent schizophrenia is often revealed when people travel abroad. Maybe if your environment and surroundings change drastically, your mind loses its sense of "self" that was based around anchors to the rest of the environment.

This journal article touches on this:

"Long distance travel has long been known to aggravate pre-existing psychosis.... Travel can be a destabilizing life event7 with many potential hazards to mental health, from the effects of drugs used for prophylaxis against infection, to homesickness, to disrupted circadian rhythms, to culture shock." http://www.ijtmgh.com/article_33029_738f7bb0f6124261891cf610...

This isn't a news site. There's no guarantee of timeliness on any of the links submitted here.

This old article could be of interest again as all schooling and most work takes place at home, over computer. A reminder of what some of the remote monitoring capabilities are, and what boundaries those in charge of them will cross.

ndespres··on Boeing 787s must be turned off and on every 51 days to prevent 'misleading data'
The 51 days in the headline popped out to me because I have a Sonicwall brand firewall I help manage which requires a reboot every 51 days or it starts dropping packets. Yesterday was day 51 and like clockwork, it started failing.
ndespres··on Ask HN: Will this be the end of Airbnb?
One thing I think we'll definitely see is a reduction in the amount of apartments available for rent on AirBnB. I've seen reports that after lockdowns went into place in Portland OR and SF, that there were thousands of new units listed on proper real-estate websites for long-term lease. That tells me that landlords who were taking units off the housing market and using them for short-term rentals, might have fewer AirBnB units after this is all done. For a while at least I think AirBnB will be more of the "rent a spare room in our house" units again, rather than the entire apartment in a major city that's displacing a long-term resident.
ndespres··on P.J. Vogt on Reply All’s “The Case of the Missing Hit”
Certainly there is. In 2008 there was a fire that destroyed many of the master tapes for old recordings, this will no doubt prevent new releases or remasters of many old albums. https://www.nytimes.com/2019/06/11/magazine/universal-fire-m...
ndespres··on Ask HN: Good ways to capture institutional knowledge?
At each of my last 3 jobs I've been a strong advocate for tracking knowledge in a Wiki. We've used MediaWiki and Confluence, and both worked well. It helps if everyone does their part to contribute, which doesn't always mean everyone has to write. Some people can dictate what they know. Some can provide screenshots. Sometimes just getting someone to leave a comment with a correction is enough. I like to start with stub articles and allow them to grow organically, without harping on folks about it.

Often there are many ways that changes are communicated (for example, an email to the NOC team to advise of systems being decommissioned, an email to the helpdesk to advise of new support procedures, etc). To some people, that email is the documentation. I know that if I want it captured in the knowledge base, that email is my cue to transpose the notification email into documentation that can be referenced later.

My current job is doing sysadmin support for a consultancy, so there are lots of clients and lots of other people doing this work. We have a regular pager rotation for emergencies, so if you get an overnight call to work on something and can't find the information about it, you start to realize how important the docs are. That has been a big motivator in getting people to update docs about the things they know. If you don't want a call overnight, make sure there's nothing that isn't in the wiki!

I use plugins to help point out when content might be out of date, and guide people to archiving out-of-date docs, or to update them. I regularly refer to Stewart Mader's great book Wikipatterns and its list of patterns/anti-patterns to help with wiki adoption and behavior. http://stewartmader.com/wikipatterns/ The book is a great read and covers a lot of your questions, especially skeptics and opponents, and how to address them.

ndespres··on More bosses give four-day workweek a try
I met with someone recently who offered 4-day workweek as a benefit, but it wasn't a 32-hour week over 4 days, it was just 4 longer days with the same number of total hours. It would be great to have 1 less commute, a 3 day weekend etc but where are the benefits of these computers that were supposed to save us all time?
ndespres··on How 1500 bytes became the MTU of the internet
If your computer sends a larger MTU than the next device upstream can handle, the packets will be fragmented leading to increased CPU usage, increased work by the driver, higher I/O on the network interface, higher CPU load on your router or modem, etc depending on where the bottleneck is. For example if you connect over Ethernet to a DSL modem, or to a router that has a DSL uplink, all your packets will be fragmented. This is because DSL uses 8 bytes per packet for PPPoE authentication. So if you send a 1500 byte packet to the modem, it will get broken up by the modem into 2 packets: one is 1492+8 bytes, and the other is 8+8 bytes.

But your PC is still sending more packets.. the modem is struggling to fragment them all and send them upstream.. its memory buffer is filling up.. your computer is retrying packets that it never got a response on..

By lowering your computer MTU to 1492 to start with, you avoid the extra work by the modem, which can have considerable speed increase.

ndespres··on Schizophrenia Manifests as a GitHub Repo
I don't believe that tcrowe is the person who put this repo up. I do think tcrowe is posting in this thread as 1000units but that's just speculation.
ndespres··on Schizophrenia Manifests as a GitHub Repo
Alright. Look at the reaction you're getting here, and the reaction you get to your attitude over on the Github thread, and consider that maybe your approach to getting your point across isn't working in your favor.
ndespres··on Schizophrenia Manifests as a GitHub Repo
I also flagged this submission. The title of the submission makes it clear that it was posted to gawk/make fun of the person posting it. They state in their manifesto that they are living in a shelter, so presumably they are already in a place where they can get help.

There are already some rude and callous comments posted on Github, and I don't think we need to bring any more there. @tcrowe is using it as an opportunity to grandstand and I don't think any more attention is needed there, either.

ndespres··on Why does gigabit internet via coax cable not offer symmetrical speed like fiber?
DSL, at least ADSL commonly found in homes, is designed that way as a good way to split the frequency available on the line to match what people need. It also shares a good portion of the frequency with POTS telephone service. There are SDSL (symmetric DSL) standards which provide fully symmetric bandwidth on the circuit. Not sure how popular it is these days but when I supported it at an ISP about 10 years ago, it was a cheap alternative to T1-class circuits.
ndespres··on Products I Wish Existed
"A view of what Accenture, CapGemini, and Deloitte keep building over and over for large enterprises. Undoubtedly a subset of these custom consulting projects can be turned into SaaS software."

I love the idea of figuring out how we can stop reinventing the wheel. Too much of this work really has no benefit to society yet keeps getting done, over and over. I wish for a way to pull the brakes and re-evaluate what it is that we are all doing exactly, and for whose benefit.

ndespres··on A Next-Generation Trash Can
I guess it's just part of why something as seemingly simple as a street corner trash can is such a challenging problem to solve. I wish I didn't need 500 lbs of safety features in my car but you need to account for bad actors, idiots on the road, and accidents. I appreciate when thought goes in to the worst-case misuses of everyday objects, even a trash can.

It also assumes that the household garbage dumper is going to carry their trash back to their house and wait for garbage day, when really they'll just drop their garbage back next to the trash can that it doesn't fit in. There's another solution to that problem, and they might have the wrong angle entirely here.

ndespres··on The Ripe NCC Has Run Out of IPv4 Addresses
Spectrum/Charter and Verizon have finally started allocating a single IP out of a /24 instead of giving me a whole /30 when all I need is one routable address. Too little too late though.
ndespres··on Difference Between Fault Tolerance, High Availability, Disaster Recovery (2014)
I like these analogies a lot. I regularly have to explain to my clients the difference between the backup system, the disaster recovery system, and the file server replication system. None of them is the same as any other, and each component has different levels of redundancy going down the stack (RAID, HA for the virtual machine, shared storage between hosts, etc) and it's no easy task to explain that yes, while component X is redundant, it does not meet the definition of "highly available" or "backed up." So I appreciate any explanation like this article that attempts to simplify and illustrate any of these definitions.
ndespres··on Igloo: A simple Windows automation tool
Your examples aren't Powershell commands, they are Windows command line utilities and could be run from command prompt. Real Powershell commands are quite intuitive, support pipelines and are object driven. Give it some credit! For example:

ndespres··on The boy behind the biggest coin-op conversion of the 80s
Are you thinking of the story of Ms Pac Man, which reverse engineered and patched the original Pac Man cabinet? I think it was Atari flying out to meet the developers. Great story either way: https://www.fastcompany.com/3067296/the-mit-dropouts-who-cre...
ndespres··on Massacre
This style of image gallery was common for the era (1995) since each image could take a minute or more to download over dialup internet connection. At those speeds even a contact sheet of thumbnails was somewhat of a luxury. I don't think the images are behind text links out of consideration for the blood of it all, but more for bandwidth conservation.
ndespres··on Microsoft introduces Windows 10 X for dual-screen devices
How about if there was a Jeep Wrangler that's actually a motorcycle but still referred to as a Wrangler, and the 4-wheeled Jeep Wrangler gets rebadged as the WranglerQuadro but only for 2 years, then they have a ATV just called "Quadro by Jeep" (not to be confused with the Jeep 4Quadro California Emissions Comploant Edition) that's more like a Microsoft branding exercise.
ndespres··on Microsoft introduces Windows 10 X for dual-screen devices
Apple's strategy is great for consumers, IT departments, and (I assume) developers in that way. I can use the same device management tools to control a corporate Macbook, Apple TV, or iPad. The differences in their product line (iPad vs iPad Pro, Macbook vs Macbook Pro, etc) all have a common denominator where you're rarely having one of those conversations where someone realizes "Oh I asked for X but procurement dept got me a 2X which is completely incompatible".

Someone posted a rant here[1] that I think about often, about Microsoft's muddying the waters of Skype, Skype for Business, OneDrive, OneDrive for Business, Windows 10, Windows 10 N, which are all different, incompatible, broken products that you would think fit together but truly don't. It's frustrating as both a consumer and an IT admin, and diminishes my faith in anything they do on this side of the market.

ndespres··on Microsoft introduces Windows 10 X for dual-screen devices
These guys just can not figure out a branding/marketing scheme that won't require overexplaining each time to figure out, and confusion by the consumer. What is a "Surface" if it's really 2 different things, with very similar names, that do completely different things and run incompatible operating systems?
ndespres··on How to Make Medieval Soap
I make soap and as far as the occupational hazards go, I rank the chemical burns further down the scale from the endless Fight Club references.
ndespres··on My Talk at Microsoft
A reference to the Good Friday Agreement, a pivotal development in the UK/Republic of Ireland peace talks.

ndespres··on Adobe Provides facial recognition Software for DHS and ICE
Proxy war? I can use my wallet, my voice, and my labor power as I please including strikes and boycotts. Isn't that how the "free market" is supposed to work?

This is the 2nd time in 24 hrs that someone has made your argument, where is it coming from?

ndespres··on Adobe Provides facial recognition Software for DHS and ICE
Ok, but sometimes our moral compass points away from these things and we need to make hard decisions to do the right thing.
ndespres··on We picked up, tracked, and analyzed 130k pieces of litter in SF
In NYC, those piles of garbage bags also have the effect of being seen as de facto garbage bins, so people will throw their litter on top of the piles as if they are some type of container to hold their trash.
ndespres··on Why Is the Amazon Rain Forest Disappearing?
Sure seems like a coup if you look at the behavior of prosecutors colluding to jail their opposition's leaders on trumped up charges.
ndespres··on The Golden Girls Would Violate Zoning Laws
On the other side of the coin, I'm in an area with NO zoning restrictions at all (other than a homophobic county-wide prohibition on pornographic bookstores). The town planning board has no power to disallow any type of building or business as long as it passes a very basic environmental survey. There's been a lot of bad feeling lately about a proposed motocross track/RV park in what is a very quiet farming community. I pity the neighbors who will have to suffer it, but there's hardly anything that can be done to stop it. I guess that's the price a community pays for constantly voting against zoning ordinances.
ndespres··on Wringing
If you're interested in how gauge blocks fit into the history of precision engineering, a new book called "The Perfectionists: How Precision Engineers Created the Modern World" puts them into context, and presents a very interesting perspective on the events and developments that brought us into modernity. These blocks feature strongly into the industrial revolution. I strongly recommend the book!
