cpitman··on Microsoft Teams outage due to expired certificate
But, somewhat annoyingly, it is only seen as applicable to the public internet. There's no effort to make ACME based CAs for non-internet usage.
cpitman··on Ask HN: What were the things you did that made the biggest impact at your work?
My experience is that often the lowest effort changes also have some of the biggest impacts. I work in consulting, and I think one of my largest impacts has been to create a pre-engagement checklist for one of our very common engagements and then getting our team to review the checklist with clients ahead of time. It took maybe a day to get the first version out, and cuts ~1-2 weeks off of our projects.

Unexpected downstream effect, this had a big enough impact that other groups started creating checklists for other kinds of scenarios.

cpitman··on Airbus ran ‘massive’ bribery scheme to win orders
No, under US law you are still responsible for bribery committed by your proxy, and have to have a process in place to ensure that all proxies follow anti bribery laws.
cpitman··on IBM Names Arvind Krishna CEO
I've been at Red Hat so long now (12 years) that it can be easy to take things for granted, but the biggest thing is just how open and transparent a company it is. There's not a lot of silo's or little kingdoms fighting each other, we're all generally working together.

For example, we're a fairly large company (10000+), but we still have an all company mailing list. And it is used by anyone to raise a concern, talk about an opportunity, etc. And that starts a conversation with anyone participating. I am on the Services side, but there is no barrier in place for me to reach out to anyone in the BU, Engineering, Marketing, whatever. I don't think I have ever had to pass a message up the chain of command for it to be passed down somewhere else, I'm just allowed to communicate when and how I need to.

The other way it comes out is that open-source has truly warped our way of thinking about things. For example, there's not a culture of restricting access to our own documents, team drives, etc. One of my peers was working on a new slide deck on a team drive, hadn't really shared it with anyone, then found out that one slide was copied into a presentation done by an EMEA team a day later. That kind of easy access and reuse is just _standard_. It applies to code, but also everything else we do.

I've worked with lots of clients through my job, and it is always eye opening when their employees are worried about "sticking out their neck" or otherwise rocking the boat. Or companies where a developer trying to talk to the business would be an incident with your manager giving you a talk. This is just completely foreign to anyone at Red Hat.

So, not working with any insider knowledge (I work for Red Hat, but reading the news like everyone else), but the other news is that Jim Whitehurst is going to be the IBM President. Hopefully a big push in keeping Red Hat's culture relevant and influencing IBM to transform.
cpitman··on Jepsen: Etcd 3.4.3
I agree they are great. I kind of miss the older style of reports though, with memes all over the place!
cpitman··on How Much Does a Mile of Road Cost?
Only tangentially related, but New Jersey has a special case of this. It used to be all in on "jug-handles" (https://en.wikipedia.org/wiki/Jughandle), where you would need to be in the rightmost lane in order to make a "left" turn. But they have also built intersections that have the standard left turn lane, on the left. You only know which one it is as you approach the intersection, then either need to get all the way to the left or right. Always a fun surprise!
cpitman··on Postdoc Myths
Is it the position or the person that is good or bad?
cpitman··on Coin washer keeps Westin St. Francis' change shiny (2010)
I'm onboard. The amount of time I have to mess with receipts is a pain, all for reimbursement. And on the other side are receipts I never had any use for, which get tossed in the trash immediately.
cpitman··on It costs $10k to ‘own’ a Chick-fil-A franchise
They also have grilled chicken variants, and wraps. Between the two, you can get an entree for a couple hundred calories.
cpitman··on Volkswagen exec admits full self-driving cars 'may never happen'
Do you mean on the tracks?

There are hard limitations on sensing onboard the train. Tracks that bend around hills, etc. I have some exposure to wireless communication for trains, and one of the limitations is that you can often not get a line of site even from one end of the train to another.

cpitman··on Volkswagen exec admits full self-driving cars 'may never happen'
FWIW, self driving trains are a very different problem. With self driving cars, the approach has been to use sensors on the vehicle and make autonomous decisions based on that input. This will never work for trains, because their stopping distances are so long that they cannot use a sensor to detect most oncoming issues.

Self driving trains will require more coordination, with central dispatch to tell them when/where to go. That leaves the intelligence on the train much more basic.

cpitman··on An alternative argument for why women leave STEM
Exactly my confusion with this article. I have multiple female friends who have earned doctorates in STEM who have either left or are planning on leaving academia to go to industry. However, they are still all going into STEM jobs!

So maybe the problem is that industry STEM is offering an overall better benefits package than academia? We're seeing the same thing in fields like AI, where academia can't retain top talent.

cpitman··on Maybe You Don't Need Kubernetes (2019)
Businesses always ask for High Availability, but they never agree on what that actually means. IE, does HA mean "Disaster Recovery", in which case rebuilding the system after an incident could qualify? Does it require active-active runtimes? Multiple data centers? Geographic distribution?

And by the way, how much are they willing to spend on their desired level of availability?

I still need a better way to run these conversations, but I'm trying to find a way to bring it back to cost. How much does an hour of downtime really cost you?

cpitman··on College students are increasingly finding ‘sugar daddies’ preferable to loans
Without further evidence, this article seems patently false. It essentially claims that over 1 in 10 American college students are looking for sugars daddies on a single website.

What seems far more likely is that, like every "matchmaking" website, there is a majority of accounts that are made up. They are obviously motivated to tout the number of young college kids in their marketing to attract the money, ie sugar daddies, to their website.

cpitman··on Judge rules that student loan debt is dischargeable in bankruptcy
Hah, no kidding. For what its worth, I grew up in a family that moved often, and was not technically in-state anywhere. If I had known that my family would also move to Maryland, College Park would have been probably where I would have aimed for. Younger siblings attended there, and with the Maryland scholarships essentially graduated debt free.
cpitman··on Judge rules that student loan debt is dischargeable in bankruptcy
Seems like you are mixing two different concepts in to "required".

If it is credential inflation, then is it providing value? Or as the grandparent said, is it just moving value around?

Are more jobs requiring college degrees because they are the most efficient way to increase productivity? Or is it because they are an easy filter, and more people have college degrees?

cpitman··on Judge rules that student loan debt is dischargeable in bankruptcy
Most students have nowhere near this much debt. The average undergraduate is accruing $15k in debt per year (https://research.collegeboard.org/trends/student-aid/highlig...) That means roughly ~$60k over four years.

Ending up with $100k+ loans is more common when people go onto professional schools (masters, law, medicine, etc), fields that should have higher earning power. Not everyone finishes, and for law not everyone that finishes gets a high paying job.

Over half of all student loan debt is held by those with advanced degrees (https://wcer.wisc.edu/docs/working-papers/Working_Paper_No_2...). Add in that only 13% of Americans 25+ have advanced degrees, compared to 35% with at least bachelors degrees.

Student loan debt is disproportionally a problem with advanced degrees, but it all gets lumped together when we talk about student loans.

cpitman··on Judge rules that student loan debt is dischargeable in bankruptcy
That's nuts. What state?

Comparing that to my alma mater (Johns Hopkins), a private university, your loans work out to more than my total cost for tuition for four years (2004-2008). Even looking up their current rates, the average four year tuition after student aid is ~130k. Without any student aid, it hits ~$200k.

cpitman··on Rete: JavaScript framework for visual programming and creating node editor
Easily the first visual programming language I used that actually sold me on the idea. Most of my experiences have been with systems that claim visual programming, but then require you to jump top code almost immediately. UE4 blueprints are sufficient to create the majority of a game.
cpitman··on Low unemployment isn’t worth much if the jobs barely pay
I travel around the US constantly, and have never heard anything remotely close to comparing unemployment with Canada. Any talk of unemployment is always internally focused, comparing the rate to the past.
cpitman··on Lime shuts in 12 markets, lays off around 100
Another advantage is that scooters place less restrictions on how you are dressed. Dresses, shoes not meant for exercise, etc.
cpitman··on US emissions fell 2.1% in 2019
I assume he means exporting manufacturing and other "dirty" industries. IE, we import rare earth based products from China because they can mine them so cheaply, at least partially because they don't have the same concern for environmental impact of the mining.
cpitman··on Elasticsearch from the Bottom Up (2013)
How has your experience with Loki been? I keep an eye on it, but haven't deployed it since it seems to be maturing still.
cpitman··on Neural Network
Is there some combination of settings that will keep the simulation from dieing out? Or is there some rule for signals propagate that requires them to "move" across the graph and not return?
cpitman··on Kansas City is first major city in U.S. to offer no-cost public transportation
That really depends on the city. In DC, my drive commute is ~10-20 minutes in the morning, and my train commute is ~40+ minutes. Why? Because I have to transfer once, and walk to and from the stations on either side.

cpitman··on Test Scores Cast Doubt on U.S. Education Reform
I think the population density was one of the points. The current system allows countries to pick the schools within a selected region, and in a high population region they can focus on top performing schools.

> that the sampling done on mainland China (Beijing, Jiangsu, Guangdong and Shanghai) and other cities was not taken from a wide variety of schools. Rather, the very best schools were chosen and the very best students were cherry-picked from those schools.

So this is more than just focusing on Massachusetts, this is picking only the best students from the best schools in Massachusetts.

cpitman··on Test Scores Cast Doubt on U.S. Education Reform
Before reading too much into China's scores, there reason to believe there is selection bias in who they are testing. In 2017, applying the same rules to the US would have resulted in it shooting up to first and second place in some subjects, which shows that methodology has a bigger impact than what we actually want to measure.
