Ask HN: Should I use a professional alias?
I'm trying to restart my life in my 30s as a software developer, and feel inhibited when it comes to setting up a bold public profile that would help me stand out as a pro.

My name is unique so it would be impossible to keep my professional life separate from my private life without using a professional alias.

Would it be a good idea to start using a professional alias? Is it likely to cause me any problems down the line? Could I use my alias on my resume instead of my real name? Would anyone involved in hiring react negatively to finding out I use an alias?

Any feedback would be appreciated. Thanks for your attention.

>Not destroying your body lifting heavy weights for 50 years seems like something people might like.

And that's why the exoskeleton system mentioned in passing in the article is more popular with construction labourers than any of these robots.

This case had a stolen slide, discovered while police were looking for stolen cats. Also they were not charged with the theft of the stolen goods found. It happened in Burbank WA though.
> I don't see marginalized minority groups getting offended at, e.g. academic studies of the Mexican experience in the US for that same sort of grouping.

I see your point but I think you are making really big bunchings of value judgments. I live in a Hispanic community. There are lots and lots of people in that group that are cishet white males, their family members aren't going to call them that, though. Not a small number of them find being cishet as only morally acceptable.

It's similar to latinx. They are terms that are used in very specific groups and mean something important there but when they get used across boundaries different groups are basically talking about different things (it's a freedom fighter/terrorist issue).

And sometimes the things that are automated were the only thing that was pleasant. It's not true for laying bricks because the heavy lifting makes it unpleasant.
The price consumers pay for something has nothing to do with the cost of producing it. Not counting the cost of the land itself, an identical house built in the city costs the same in hours and materials as one in the country. Price is determined by one thing, and one thing only: how much other people are willing to pay for it (i.e. the market sets the prices).

The costs vs sale price are relevant to the builder in making the decision on whether to build and whether to sell, as they wouldn’t do it if they’re going to lose money.
Ask HN: What are relevant problems in CS except for AI and blockchain?
I've recently read "You and your research" (link: http://www.cs.virginia.edu/~robins/YouAndYourResearch.html) about great scientists and become interested: what are actual unsolved problems in CS field for which we have a workable attack surface? It seems like everyone keeps talking about AI and blockchain, but it
have become increasingly complicated to distinguish between hype and actual progress. Answers to the same question but in the related fields would suffice too, e.g.: There's some noticeable progress in the protein folding problem, but it's made via neural networks, if I understand correctly.
It’s important to note the “workable attack surface” part of the question, meaning that P = NP is an unsolved problem, but I doubt anyone understands how to approach solving it.
Ask HN: Starting a Project with Payments in Mind
i wanted to reach out to the community and ask for a few pointers/caveats regarding a new project that i would like to start. as i have limited experience with payment systems, i am interested in finding out what are the things that should be set up from the get go when aiming for

1) a tool which will require montly payments (per user, or other metric)

2) if an application requires other underlying tech that a customer does not already have (industry with low technology penetration), is it ok to simply pass on the expense/fees? are third parties typically agreeable to bringing in business to them for a discount (e.g. my process requires saas tool X that charges $Y/user/month)? how are such services typically passed on to a new clint of my own if said service is a requirement for me?

3) what to look out for when having to migrate users in an industry when they have no software/tools and must take on all new tech?

cheers
Not just test! Real users need to be there from the requirements stage.
This problem was discussed by Pratt and Dunlop in their 2019 policy paper for the National Centre for Climate Restoration:

> Climate scientists may err on the side of “least drama”, whose causes may include adherence to the scientific norms of restraint, objectivity and skepticism, and may underpredict or down-play future climate changes. In 2007, security analysts warned that, in the two previous decades, scientific predictions in the climate-change arena had consistently under-estimated the severity of what actually transpired.

> This problem persists, notably in the work of the Intergovernmental Panel on Climate Change (IPCC), whose Assessment Reports exhibit a one-sided reliance on general climate models, which incorporate important climate processes, but do not include all of the processes that can contribute to system feedbacks, compound extreme events, and abrupt and/or irreversible changes.

> Other forms of knowledge are downplayed, including paleoclimatology, expert advice, and semi-empirical models. IPCC reports present detailed, quantified, complex modelling results, but then briefly note more severe, non-linear, system-change possibilities in a descriptive, non-quantified form. Because policymakers and the media are often drawn to headline numbers, this approach results in less attention being given to the most devastating, difficult-to-quantify outcomes.

> In one example, the IPCC’s Fifth Assessment Report in 2014 projected a sea-level rise of 0.55-0.82 metre by 2100, but said “levels above the likely range cannot be reliably evaluated”. By way of comparison, the higher of two US Department of Defence scenarios is a two-metre rise by 2100, and the “extreme” scenario developed by a number of US government agencies is 2.5 metres by 2100.

> Another example is the recent IPCC 1.5°C report, which projected that warming would continue at the current rate of ~0.2°C per decade and reach the 1.5°C mark around 2040. However the 1.5°C boundary is likely to be passed in half that time, around 2030, and the 2°C boundary around 2045, due to accelerating anthropogenic emissions, decreased aerosol loading and changing ocean circulation conditions.
Ignore my last sentence then. All I mean is, I get paid the same whether I put in half effort or full effort. Full effort, which can lead to burnout and stress, is a cost to me. Why would I increase personal cost with no monetary compensation for doing so? They're already paying me for half effort and I keep being told that I'm doing a great job. So I'm not going to go out of my way to do more.

Edit: if I could double my output and know that my salary would double too, I'd do it in a heartbeat. But I've never found a company with a comp structure that can actually achieve that. It's far more effective to just go on autopilot for a year or two, then get a 30% raise at a new job. Rinse and repeat.
This was Chrome on Linux. I had a crosshair cursor in the centre of the screen, and the mouse was just doing looking, so I had to look in a direction that made the button move under the cursor (or something like that - I'm now elsewhere so can't check).
Yes, and also, this is an extraordinarily complex design to implement and get right. Java more or less failed in contexts where it was expected to actually enforce those boundaries reliably - untrusted applets on the web. It's working great in cases where the entire Java runtime and all libraries are at the same trust level and sandboxing/access control measures, if any, are applied outside the whole process - web servers, unsandboxed desktop applications like Bazel or Minecraft, Android applications, etc. Security vulnerabilities in Java-for-running-untrusted-applets happened all the time; security vulnerabilities that require you to update the JRE on your backend web servers are much rarer.

If you make a security boundary, people are going to rely on it / trust it, and if people rely on it, attackers are going to attack it for real. Making attacks harder isn't enough; some attacker will just figure it out, because there's an incentive for them to do so. It is often safer in practice not to set up the boundary at all so that people don't rely on it.

4) Other people form their opinion based on 1), 2), 3)

Predictable. I've known for the better part of a year, that certain groupthink crowds would start to go after Elon Musk. The groupthink crowds eventually go after anyone who thinks for themselves and refuses to bend the knee.

Instead of facts, they use circular references and guilt by association. Also: The phenomenon I just described is independent of point on the political spectrum.
> The effect of combating so-called "abuse"

We’re talking about people who are stealing money meant for unemployed people and you can’t even bring yourself to admitting that is even a problem. If you’re going to scare quote “abuse”, why don’t you steal from unemployment as well since you don’t seem to think there is anything wrong with it?

> percentage will just give up and suffer.

This is already happening with the existing paperwork. What are you doing to advocate that people don’t even need to pick up the phone or get out of bed to get their unemployment?

> You understand this, right?

You understand that rampant fraud can cause the collapse of the entire setup right?
Having respect for the skills of a worker and also believing that they are possible to automate are not mutually exclusive. It's no different from people saying the same thing about chess and chess players, or go and go players, before the problem was solved.

And it's not just blue collar workers that are a target of this idea. We are already starting to see automated programming moving out of the research lab and into the commercial realm, e.g. GitHub copilot.
The analysis looks very reductive and seems to ignore the scientific knowledge about what motivates employees to quit/stay.

One thing we know for sure: most people don't quit a company, they quit a manager. Companies are traditionally bad at identifying good managers. I think poor loyalty is mostly symptomatic of poor management.
I would bet a lot more than 50c that the CCP isn't involved in a state-sponsored campaign to berate their own athletes, undermine social cohesion and tip the scales more in the favour of a cultural revolution 2.0.
Spreadsheet is incredibly powerful

However, if your use case is narrower (e.g. only use CSVs), there are more suitable tools.

As a person who knows how to code, using a real programming language or SQL is way way better.

To that end, I've built a Desktop app that enables you to work with CSV using SQL here: https://superintendent.app
Camera is made of materials which need to be mined, transported, refined, milled, soldered, molded, etc.

So quite a lot of energy has been used to make the camera. It is not really about of the chemical bonds in the camera, but about the the energy the whole manufacturing chain uses.
I'm trying to keep details light in order to stay anonymous. The take away is that I want to leave and sooner rather than later.

I've already talked with management and the offending behavior has been flagged as "not ok", but I was the one punished. The offenders are on the list to be promoted. Thus, I'm leaving.

The career break isn't necessarily related to the workplace issues, but the drama has burnt me out. Taking 6mo-1yr to recharge and work on random stuff would be great mentally.
As if that $150M were paid in cash alone. The majority of it is in stock, because of course it is.
How do you mean? I'm sure even with flat yields people in that camp will be far better off than the average person since one of the prerequisites is getting assets equal to 20-30x your annual expense
> There are many other things that are overvalued, such as real estate

I'm not sure RE is overvalued. There's a shortage of houses at a time when Millennials (the largest generational cohort so far) are hitting peak household formation.

> Now, there is money that holds its buying power

Bitcoin peaked at around $64K in April 2020. Now it's currently at $38K - it was down to about $30K a month ago. Seems pretty volatile for something that "holds it's buying power".
This was a growing company making an active effort to pay market rate - I realize this doesn't apply to everywhere.

At the point where the market rate has shifted that much and my employer hasn't caught on, I'm out the door myself. ;)

"Maybe the replacements suck in comparison" is certainly something we would've noticed - happily, it wasn't the case.

But we were hiring basically constantly, since there was no team that had enough people for the work the company wanted to do, even before attrition. So we had a good feel for what we could get for the money. If someone on the team can do better elsewhere, though, more power to them - I would certainly take that opportunity too.
No, because employees decide where to live and how to commute, which determines the cost of commuting. An employer paying for all commuting expenses would encourage employees to live farther away and to take Uber instead of public transit.
I used to do this at home all the time (from Linux though): networked printer with its own IP address and then good old netcat. I'd do it with PostScript files and send them to HP LaserJet 4M+: not only do these beauties speak PostScript natively, they can also be made to display the infamous "PC LOAD LETTER" message.

I'd try to find these printers used then I'd upgrade them: more RAM, more fonts, adding a network card inside the printer etc.

I still have several of these printers in a garage, some of them have printed more than 300 000 pages. They probably still work: some things were that good back then.

And, yup, there's something feeling magical when netcat'ing a .ps file (or another format) directly to the printer.
This is delusional. We're extremely far away from automating the entirety of society.

As people have less kids, age out of the workforce, and live longer, who's going to pick the crops? People far away in 3rd world nations? Who's going to be working the jobs to pay them? Do we expect the small amount of working-age people to support themselves + their kids + retired parents + grandparents? Who's going to be the nurses and the firefighters?

Japan and Germany both have aging populaces and low birth rates. Germany is taking the immigration route, and Japan is taking the automation route (as it's much more xenophobic). From a macroeconomic perspective, Germany's strategy seems to be winning.

And I don't know about you, but when I'm old, I'll take a human nurse over a robot nurse any day of the week.
It's always a little weird the jobs that are easy to automate vs the jobs that are hard to automate.

Jobs that require interaction with the physical world and people will almost always be a hard to automate thing. There are simply too many variables.

The real problem is when we make the results of a job worse to aid in automation. The prime example here is tomatoes being breed with thick skin, picked before ripened, and then squirted with some chemicals to make them red so people will buy them. All while sacrificing taste.
People also seem to always miss that we always engineer the product in order to be able to automate it.

The most automated things have been designed by engineers with robotic assembly in mind.

You're confusing static, dynamic and total pressures. Static pressure is the pressure of a fluid on a body when the body is at rest relative to the fluid. Dynamic pressure is the velocity created pressure. Total pressure is the sum of the two, and is what is used in the ideal gas law. To compute lift force static pressure is what is integrated around the wing surface. Total pressure remains constant in the fluid flow for low Mach numbers. Static pressure can and absolutely does change significantly as it accelerates through a streamline such as in low-speed aerodynamics. I understand the semantics on the different kinds of pressure can be confusing. But you should know that when aerodynamics refers to "pressure" as it applies to lift generation, they are referring to static pressure.

I should also mention that this pressure absolutely does change a lot over the flow field, and is commonly used to experimentally and mathematically quantify lift. The following is an image of the pressure distribution of a NACA 2412 airfoil at low speeds.

https://www.chegg.com/homework-help/questions-and-answers/n-...

Just to explain the chart a little bit, in aerodynamics, pressure is usually simplified to a Pressure Coefficient (CP) value. A CP of 0 is when static pressure equals atmosphere. A CP value of 1 occurs at the stagnation point (where velocity is 0, therefore static pressure equals total pressure). Note how this type of chart has an inverted y-axis (a common convention so that the wing upper surface is at the top). Notice how the static pressure on the lower surface is roughly atmospheric, while the upper surface pressure suction peak is high. In this case roughly equal in magnitude to the dynamic pressure. This is a typical pressure distribution for most airfoils, with the suction peak increasing in magnitude as angle of attack increases.

This plot can be obtained mathematically using some sort of potential flow scheme (see: XFOIL for 2D airfoils), or experimentally using pressure taps on a wind tunnel model. The area between the upper and lower surface curves is directly proportional to lift. The larger the difference between upper and lower surfaces, the more lift.

1. Fish do not, in fact, use oil in their livers for buoyancy. They have an "air bladder", which you may read about. You might have heard something, somewhere about shark livers. Fish are much more closely related to you than to sharks, so it is a big error.

2. Buoyancy in air has been achieved with an industrial level of success using hydrogen. Producing hydrogen is easily within the energetic range of biological processes. Air-buoyant animals could have existed for millions, even hundreds of millions of years before being outcompeted by pterosaurs and birds, and then left no trace.

2. Some sort of underground markets for other means of transfering money like gift cards and such;

3. create a parallel economy via some sort of bartering system in countries where digital means are not exactly widely adopted in rural areas;
I think there are pros/cons of car culture and systems in both countries.

Japan's car-ownership experience is rather hostile. Expensive tolls, Shaken inspection, and higher price tags than SK. In a way, this benefits tourists because streets are cleaner, cars are newer, and people tend to drive less.

In Korea, it's flipped. It's great place for car ownership. But from tourists POV, it's chaos.

As much as I love Japan, I'd prefer to live in Korea while visit Japan as tourist. Seoul isn't so bad once you go outside from central Seoul to new cities. Everything is more spread out, cleaner, and very modern.
This is nihilistic and terribly misinformed. A LOT of foundational economic activity is what we derisively call "unskilled labor," performed by the very "semi-educated humans" you're talking about.

In the US alone, we literally import seasonal workers to prop up our agriculture industry. We pay them just enough to survive, give them few rights and little stability, and generally tread them as an underclass.

People like this undergird the whole of the modern global economy.
If your job in SFO can be done from Sacramento or Portland, why can’t it be done from Manila? Or Warsaw? If your answer is “time zones”, then why not Bogota? Or Buenos Aries?

It may seem fun and flexible now, but the acceptance of fully-remote work will lead to jobs being hired globally, at lower cost to the company than hiring domestically.

And don’t fool yourself, that developer in Colombia is just as talented but can work for half the cost.
>such "wear and tear" is not covered under warranty.

Surprising - this same issue has happened to me multiple times with multiple power bricks but fortunately Apple replaced them every time.

I am very careful with the power bricks, but I think it's a design flaw of the old integrated cable design and strain relief which didn't do what it was supposed to do. As I noted, each time I brought a failed brick in they replaced it under AppleCare.

The old magsafe power brick design would tend to fray and fail at the strain relief points - either the one next to the power brick or the one near to the magsafe connector. I've seen the issue repeatedly for multiple other users as well - users who are not rough with the power brick or the computer.

Fortunately the current USB C power bricks have removable AC and USB C cables so they basically eliminated the issue from the integrated cable failing at the strain release point.
Exactly. You look at turnout rate and/or sample the crowd as to how they learned about it.
