mattlutze··on Less screen time and more sleep critical for preventing depression
The researchers appear to have tried to look at Sedentary Screen Time, but had to correlate passive TV watching and non-work computer use as those were the questions from the data bank they sampled.

mattlutze··on Less screen time and more sleep critical for preventing depression
The researchers attempted to control for this:

"Sedentary screen time Sedentary screen time is calculated in hours per week, adding together the participants’ answers to the questions ‘In a typical DAY, how many hours do you spend watching TV?’ (FC: 1070) and ‘In a typical DAY, how many hours do you spend using a computer? (not including time using a computer at work)’ (FC: 1080)."

mattlutze··on Your Computer Isn't Yours
Solutions like "switch to ___ manufacturer and run Linux" are great and relatively accessible for folks in the tech/IT crowd.

1. What do we do for family members embedded in the Apple, Google, Microsoft ecosystems? 2. How do we help move our companies and non-tech colleagues off of Windows and the Microsoft cloud behemoth?

mattlutze··on Group of Google critics calls for EU antitrust action
In a maximally capitalist system, corporations are only incentivised to make changes when those changes improve their profit generation. If environmental improvements would decrease net income, they generally won't do it on their own as it would be inefficient.

Similarly, companies won't generally elect to weaken their bargaining position with employees, such as paying higher wages, reducing working hours, providing PTO or fair hiring/firing practices.

One of the main purposes of government is to represent the will and interests of the general person, whether that's internationally or in collaboration with the companies that provide jobs.

mattlutze··on OAuth 3
Benefit of a mailing list is that you have a wonderful distributed history of a thing, don’t have to own & maintain a large website/app, and everyone has some way to have and use email for free
mattlutze··on OAuth 3
These are two great discussions to raise in the working group communications. If you go through the link that they've shared, you can sign up directly and participate in the conversation about how they architect the v3 rebuild.
mattlutze··on OAuth 3
For everyone that has comments and questions, the best way to get them discussed and considered is to join the IETF working group mailing list and starting to participate.

As a student I've previously sat on a couple of mailing lists for the academic benefit of learning from some really smart/dedicated people. Joining and participating is open and just requires you to sign up. The signup link is on the announcement page above ^

mattlutze··on Coinbase offers exit package for employees not comfortable with its mission
We're all faced with a difficult challenge in how to balance personal expression and professional conduct. It's especially difficult as shelter-at-home mandates push our work lives into our private spaces.

It's a good thing to try to be so generous with supporting an exit over values alignment. It's unfortunate, though not surprising, for Armstrong to want Coinbase to be like other for-profit financial firms -- quietly amassing wealth and influence vs. noisily in the spotlight.

mattlutze··on Democratic regression in comparative perspective: scope, methods, and causes
National politics has been global for as long as we've had international trade. The way in which we experience that has changed though, and perhaps more of us now are able to see the extra-national players in any particular field.
mattlutze··on Karpathy's MinGPT
Distributed training is indeed a thing! A few random Arxiv pulls:

https://arxiv.org/abs/2007.03970 https://arxiv.org/abs/1802.09941

Efficiency and resource cost is the big question though. You don't pay for the electricity or part wear that you don't use, and home computers or workstations may not be as efficient at performing a training run vs a task-specific setup. AI@home might end up costing even more, and increase the footprint of the model more, than doing it all together.

Part of the magic really needed is finding simpler ways to achieve the same levels of model robustness.

mattlutze··on Amazon’s New Competitive Advantage: Putting Its Own Products First
It's not hard at all to say consumers are on the losing end when a monopolistic company controls product discovery.

Amazon getting the sales reduces income to anyone else selling, and when Amazon is almost the only place to sell, smaller companies will go under and new ones will have a harder time starting.

mattlutze··on Germany, France launch Gaia-X platform in bid for ‘tech sovereignty’
There are many billions of Euro worth of renovation, modernization and simplification in the Mittlestand.
mattlutze··on Germany, France launch Gaia-X platform in bid for ‘tech sovereignty’
But we are super proud of coining Industrie 4.0, so, that's something.

It would be wonderful to see more free and open innovation and investment in a couple of bleeding-edge tech centers in Germany. A lot of the big internationals are in Munich and Berlin is slowly growing steam for startups, but it's a disappointment to me that there's so many Germans with so much wealth prime for investment and creating a culture of exploration, but instead it sits in real estate or something.

mattlutze··on Apple crushes one-man repair shop in Norway’s Supreme Court
Certainly, this is why I've not made a universal claim above. I have indeed partially rebuilt a couple cars. I generally support right to repair. I recognise that anything against that is anathema here but there's some cases where we need to be able to make exceptions.

Someone buying a refurbished powerbank, for example, may end up lighting something on fire because it was repaired incorrectly.

Yes it'd maybe be on the manufacturer of a replacement regulator if an insulin pump was 3rd-party repaired and failed, but would it maybe be safer to say that the device should be modified or repaired only within its certified supply chain?

There's CE and UL listings for communications and electrical devices to in part protect consumers against poor manufacturing leading to irradiated or electrocuted people.

Could we agree that there's a difference between a bushing and a microcontroller?

mattlutze··on Apple crushes one-man repair shop in Norway’s Supreme Court
There are some legitimate and common-sense applications of "terms of service" in physical products. You wouldn't want someone removing a battery from one device to try and retrofit into another and then sell the refurbished device as safe. Inevitable problems could be both a safety issue and injure the reputation of the company.

Whether a phone or watch generally is one of those sorts of products though is certainly something to debate.

mattlutze··on I was blackmailed – any YouTuber could be next
At some point you start getting lots of customers who purchase less but are more likely to require significant customer support resources for what they do purchase. At scale, things that might have looked O(n) at one volume of customers can change.

Even if you could double your customer support resources, it means a very different structure and needing to ensure you both hire in the same quality of employees up and down the escalation chain as well as adapt your organization to handle the vastly larger communication and problem resolution processes.

Noe of that is trivial and it's quite easy to take a great org and make it terrible by just adding a bunch of people.

mattlutze··on The death of corporate research labs
This is how my advisor and I reshaped my recent masters thesis. I was thinking of an engineering problem, but he reminded me of some really cool ways we could do basic science. It ended up being really rewarding and still novel.
mattlutze··on Employers are rethinking open-plan office design
I hear where you're coming from, but have you been a part of a real estate search process for office space?

Open offices are crazy cheaper, and most retail developers don't build real offices anymore (and or when they renovate a commercial property pull all these walls out).

It is about cost, for anywhere I've worked or any clients I worked for. I haven't ever known a manager that wanted an open office to control or oppress their staff.

This is (mostly) why new occupancy tech exists as well btw -- the "crotch sensors". Not usually for specific employee surveillance, but to map occupancy trends and determine what parts of a space can be hot-desked or otherwise over-assigned to further reduce space requirements.

mattlutze··on The death of corporate research labs
Well, a lot of / most of deep machine learning breakthroughs are coming directly from research scientists at Facebook, Google, NVIDIA, (other major tech companies) or research organizations associated with them or their executives.

It's difficult for academic labs to keep up, actually.

Whilst modern economics and the startup model makes it easier for companies to let startups do the actual idea testing (and then buy up the successful experiments), there's a ton of companies that are still driving entire industries with their corporate-funded research.

We should also probably note that a lot of the funding for some very successful academic labs comes from these large corporations as well.

mattlutze··on The Kawaiization of Product Design
Emoji are a native part of the vocabulary of a couple generations now. What you might be noticing is a platform signaling that it's supporting those folks as well.

Every Millennial is an adult, as are many Gen Z'ers, and these plus the first all-21st century generation are going to have come to expect emoji to exist and existed in digital spaces where emoji are a part of the jargon.

Why would it make sense for Reddit to force these people to communicate less completely than they are used to doing?

mattlutze··on Sell Yourself, Sell Your Work
"It helps to reframe the issue. "Selling" yourself is distasteful for many, because it smacks not only of loudness & brashness, but of straight up lying."

I think a lot of folks think franchise auto dealers or traveling Hoover reps when they think about "selling". I've always found that sort of "get someone to give me their money for something no matter what" process is better equated with "hustling".

I have a few great relationships with real salespeople through my work, and for them it's about lining up their products with the people that truly need them for the price the products need to sell at.

I've tried to learn that as a lesson for self-advocacy and network building as well. I actually don't mind a cold call on LinkedIn from someone where our work might really benefit each other.

mattlutze··on Rules of thumb for a 1x developer
Have you actually tried applying, though? Rules are general, locations can be hypothetical or ideal, remote work is a thing.

(To be sure, I get your point. But I think this anecdote might be a little bit your own barriers to that route as well as recruiters just spamming people that match keywords.)

mattlutze··on Are Ideas Getting Harder to Find?
There are many, many things that these sectors need that are not yet invented. And quite frankly, while an existing solution might work in for their cases, unless it works in the confines of the regulatory environment of medical and government, then it’s not an actual solution.

Those peculiarities are part of the yet-to-be-discovered solutions, not just annoying barriers to adopting existing products.

mattlutze··on CryptoCam: Privacy Conscious Open Circuit Television
The real benefit inspired by the authors might be in a logging scheme for moving in surveilled spaces. When I pass through a bounded space, my tracker app gets a log of the camera whose space I moved through. If you wanted to request the footage you’d have a 2-party confirmed list of cameras and times to request, reducing impact of a request and potentially increasing East of compliance.

This would be difficult still without fine-detail geographic bounding via maybe Bluetooth and likely very expensive to retrofit into existing systems, but would also still protect other private individuals’ privacy and security. Released footage could still be masked, for example, and access and use encouraged to be more directly audited.

mattlutze··on CryptoCam: Privacy Conscious Open Circuit Television
A lot of this proposal is interesting, but the proposed invention is really concerning. The proposed CryptoCam (section 5) in particular ignores the privacy rights of recorded individuals in an attempt to offer greater access to recorded footage.

Section 5, the proposed CryptoCam, is to me the most concerning. The proposed solution would use location-awareness communicated from a recording subject's digital proxy in order to collect encryption keys to later access footage that they may have been a subject in.

This gives a person access to:

1. The biometric information of private individuals, based only on their proximity to those individuals (faces are incredibly sensitive information) 2. Any intellectual property or sensitive information that may have been visible during the period that they passed through a space.

Someone intending to perform an illicit activity need only wander through a space and receive the exact perspectives and resolutions of existing cameras in order to summarily defeat the protective capabilities of that video surveillance deployment.

There's so many new ways a system like this can be abused, and the proposed setup doesn't reduce any existing abuse vectors.

2 additional concerns:

There exists with video surveillance today an understanding that one or more agent is watching, recording or analysing footage, and that footage may exist for some period of time. Benefits of video surveillance may include deterring illicit activities, particularly when the location and perspective of cameras is generally but not specifically known.

3.2 suggests a framework for access, but I do not, at first read, understand a change being proposed from what is currently industry standard practice; access to recorded footage is generally need-based and restrictive.

3.3.1 suggests new mechanisms for exposing some of this information (active vs passive monitoring, whether recording exists). I mention it above but the partial Panopticon effect is one of the main reasons video surveillance has a deterring effect.

mattlutze··on Adult immune systems ‘remember’ germs to which they’ve never been exposed (2013)
Humans produce colostrum early after birth as well. There's a practice of saving it if the mother produces enough milk in case the newborn later has an illness and could use the antibody boost.

mattlutze··on Technical Writing Courses
After reading some of the comments here, I'm wondering if people are actually following the link and reviewing the content.

The two courses are well-structured. Each course has an overall outline listing each lesson, and each lesson has a table of contents to overview the topics therein. The courses highlight major key topics in technical writing and does so with easy-to-internalize (tenets). I'd have loved for my university coursework to be so clearly organized.

Some highlights include defining your audience[1], engaging your audience[2] and reviewing how short and clear sentences improve comprehension[3].

mattlutze··on Technical Writing Courses
There's a lesson overview on the left-side navigation, and an inner-lesson table of contents on the right-side navigation, which links to each topic or learning objective.

If you're on a narrow format it looks like that table of contents is set into the top of the article below the lesson title.

mattlutze··on Covid-19 Open Research Dataset
Here, I would recommend that mortality rates are not bad. The goal in risk communication is to instill a level of concern equal to the current threat. It's all about context.

If you show infection, death and recovery rates, you have to provide context and help people understand what a thing means.

1-10 scales can make parsing difficult (3 and 4 have the same description right now, for example). Governments, militaries and emergency aid orgs put a lot of effort into color and coding systems.

Give Peter Sandman a Google, and check out his site here:

https://www.psandman.com/

He's an expert in how to talk about scary, hard-to-visualize things (like a viral pandemic).

Also, how old is the data being drawn from, what algorithm do you use to de-conflict the sources, and how do you disclose this to your audience (other than the general about page)? If a source has different refresh rates for countries that it tracks, how are you reflecting that to your audience?

A note, China is missing from your nifty "First 20 days" graph, which maybe you should just call "First 20 days after 200 cases" or something like this to make it clearer what's being tracked.
