gavman··on Why Nerds Are Unpopular (2003)
Looking back, the thing I wish someone in middle/high school pointed out to me is how temporary it is. Day in and day out it's your entire life and you think it goes on like that forever, and then one day you graduate and poof it all disappears. I remember the day after I graduated it sunk in that I'd never be in that world again and this huge feeling of relief and excitement washed over me...and then I remember feeling so stupid for being so blind to the fact that high school ends and you leave that world behind. But while you're in the middle of it--and for me even right up until I graduated--it really did feel like it went on forever.
gavman··on Ask HN: Who is hiring? (January 2017)
HawXeye (http://www.hawxeye.net/) | Pittsburgh | Full-time or Part-time | ONSITE or REMOTE | Project Leader/Full Stack Engineer

HawXeye was founded in the summer of 2014, spinning out of the CyLab Biometrics Center at Carnegie Mellon University (https://www.cylab.cmu.edu/research/center-biometrics.html). Our goal is to bring advanced video analytics, typically only available to top end corporate security systems, to home users. Our company specializes in embedded systems and machine learning, and especially trying to bridge the gap between the two. Our core office is in Pittsburgh, but we have remote team members based out of Boston, Seattle, and SF as well. We are fully funded.

We are looking to hire a Project Leader/Full Stack Engineer to head a new team and own a new web application project. The hire will have a lot freedom to design and implement the application from scratch.

Our interview process is straightforward consisting of 2-3 phone screens, and possibly an on-site in Pittsburgh.

Shoot me (Gavriel) an email at gadler@hawxeye.net if interested or would like to talk more about the company/position.

gavman··on The pension gap
>Asked to study differing scenarios for the financial markets, Seeling told the CalPERS board that if the pension fund’s investments grew at about half the projected rate of 8.25% per year on average, the consequences would be “fairly catastrophic.”

8.25% per year? No one averages 8% per year growth. That's not even an optimistic projection, just a stupid one.

gavman··on I am an investor in The Style Club. Or, at least, I thought I was
From everything I've read, the handshake deal on the show is meaningless. After the show the investors do real due diligence, and not every deal works out.

"First of all, the handshake deal that happens on the show isn't anything binding. Filming for each season is split over the start of the summer and the start of the fall. After each round, the Sharks and their teams do due diligence on each of the companies to ensure that everything within the company is how it was represented in the pitch room.

There are times when the numbers check out, but the entrepreneurs decide they no longer want to make a deal, such as when the founders of evREwares decided they weren't actually willing to sell 100% of their struggling company to Cuban for $200,000 as they agreed to in season six.

Ultimately, said Cuban's fellow Shark Daymond John, about 80% of season seven's deals made on camera closed, which is up from about 60% to 70% of past seasons."

gavman··on George Hotz cancels his Tesla Autopilot-like ‘comma one’
By "we want to shut you down" I meant the NHTSA isn't presenting him with so many regulations and requirements that meeting them is impossible, effectively ending the product. They are definitely using the fine to force him to comply with their request to meet the very minimum bar of answering their questions about his product. This, as mentioned, makes total sense to me in terms of what government should do to protect the safety of its citizens.

Edit: grammar

gavman··on George Hotz cancels his Tesla Autopilot-like ‘comma one’
Exactly. The NHTSA memo seems extremely reasonable to me. If you're going to put to market a product where the smallest malfunction could easily kill many people (both those using your product and those around them), answering a couple regulation questions seems like a small hurdle to pass. Nothing here is saying "we want to shut you down", it's saying "we want to make sure you pass the most basic safety standards". That's an obvious part of a government's duty to keep it's citizens safe.
gavman··on Be Kind
I had an intern for the first time last summer! I tried my best to focus on being as encouraging as I could and helping him whenever he ran into trouble. He clearly was working very hard and doing his best, so I focused on being as supportive as possible and praising the work he did (which was very good!). If I'm being honest though, we was a really terrific intern and we never ran into a situation like I did, so I wouldn't say it was much of a test :)
gavman··on Be Kind
This was so nice to read. I think back to my very first coding internship after my freshman year of college when I messed up big time. I made a bad mistake that ended up forcing my supervisor to put down everything he was working on for a full afternoon and do an emergency fix. I so vividly remember sitting down in his office, trying to just calm down and keep it together. He never got upset or annoyed (at least he never showed it), instead he listened to me explain what I had done, figured out what was wrong, showed me what my mistake was, fixed everything up, and calmly walked me through the entire process, turning it into a learning experience. At the end he asked me some questions to make sure I understood everything that happened and told me "everyone makes mistakes, don't sweat it, just make sure you learn from it" and that was that. I remember leaving his office that day thinking "if I ever make it to the point where I have my own interns, I'm going to do everything I can to support them and treat them as well as he treated me." A little kindness really does go a long way!
gavman··on Statistical Machine Learning, Spring 2016
Recent CMU alum here ('15). 10-701/702 are the intense higher level courses meant for ML PhD students. If you want something a little less mathematically rigorous and a little more application focused, consider the masters version of the course, 10-601. All if its material is available here online as well [1]. That said, if you are willing to put in the effort and have the mathematical background to tackle 701/702, you definitely won't leave disappointed.

gavman··on Facebook, Amazon, Google, IBM and Microsoft Create Partnership on AI
>>"As of today’s launch, companies like Apple, Twitter, Intel and Baidu are missing from the group. Though Apple is said to be enthusiastic about the project, their absence is still notable because the company has fallen behind in artificial intelligence when compared to its rivals — many of which are part of this new group."

It seems Apple's lack of engagement in the community [1] is really starting to hurt it. Did anyone else take away from this that the other big players are not including them at the table/considering them real competition?

gavman··on I Love the U.N., but It Is Failing
The UN has a lot of problems beyond just its bureaucracy. I'm suspicious of it's ability to solve the problems it claims it exists to solve even if its bureaucracy was extremely efficient. It seems I read UN scandals on a monthly basis, to recall a few from the past few months:

Sexual abuse by it's peacekeepers (http://www.washingtonpost.com/sf/world/2016/02/27/peacekeepe...). "Child sexual abuse by UN peacekeepers" even has its own wiki page (https://en.wikipedia.org/wiki/Child_sexual_abuse_by_UN_peace...)

Bribes are abound, even a story earlier today (http://www.seattletimes.com/business/humanitarian-worker-cha..., http://nypost.com/2015/10/06/former-general-assembly-preside...).

Saudi Arabia is on the human rights council (http://www.thedailybeast.com/articles/2015/09/22/why-is-saud...). Not exactly a "scandal" but in the same vein.

It's ever-increasingly hard to take the organization seriously.

gavman··on Harper Lee has died
Harper Lee was a "one hit wonder", but the "one hit" was more than enough in terms of contribution to American literature. Very sad news indeed.
gavman··on My Little Sister Taught Me How to “Snapchat Like the Teens”
> Plus, you are (were) one of the dorks and your sister is one of the cool kids. The two groups have noticeably different modes of socialising.

Very true. And like some of the other commentors are pointing out, it's somewhat sad that the old, more "natural" communities built over time are becoming a dying breed.

gavman··on My Little Sister Taught Me How to “Snapchat Like the Teens”
It's amazing that at age 22 I've already seemingly "aged-out" of being an early adopter/power user of new social media (not that Snapchat is new, but I use it maybe once or twice a day and I've never even heard of "Triller" and "VSCO"). My 15 year old sister is always rolling her eyes telling me how to "correctly" use my existing social media apps and I've never heard of most of the new apps she's into.

Thanks!!
gavman··on Graphene optical lens 200 nm thick breaks the diffraction limit
As I said in a comment below, he's at a top tier program (CMU), so it's likely I didn't understand his adverse reaction. You mention below his/his advisor's adverse reaction may be about "a movement to move to no cost journals", not about reputation. When I see him tonight I'll ask.
gavman··on Graphene optical lens 200 nm thick breaks the diffraction limit
It's clear at this point I must have mis-understood his response. He's at a top tier school (CMU) so my guess is he knows what he's talking about. Apologies.
gavman··on Graphene optical lens 200 nm thick breaks the diffraction limit
I talked to my apartment mate about it. He said that when he showed the article to his advisor, she had the reaction of "they're pay to publish". I can't speak to the reputability of the journal, just providing his response.
gavman··on Graphene optical lens 200 nm thick breaks the diffraction limit
My apartment mate (currently a PhD student in Chemistry) noted that the research is cool, but article this is based on in Nature Communications is pay to publish, so err on the side of skepticism.

A quick Google search found this:

http://www.the-scientist.com/?articles.view/articleNo/41072/...

"At present, researchers can choose an open-access option when submitting a manuscript to the journal, selecting one of three publishing licenses: Creative Commons Attribution 3.0 Unported (CC BY), the more restrictive Creative Commons Attribution-NonCommercial-No Derivs 3.0 Unported (CC BY-NC-ND), or Attribution-NonCommercial-ShareAlike 3.0 Unported (CC BY-NC-SA). Authors pay a fee of $5,200 to publish a study under a CC BY license, and $4,800 for each of the other two... Update (September 23): After this article was published, Nature Publishing Group's Amy Bourke responded to The Scientist, noting the flat article processing charge (APC) to publish in Nature Communications: $5,200"

Edit: other users seem to note that the journal is very reputable. I do not know myself, was reporting my apartment mate's reaction since he is much more knowledgeable in the area. It is clear from conversation I mis-understood his response. Apologies.

gavman··on Why Learn to Program in C?
While I agree with the premise that it is important to know C, I also agree with many of the comments here suggesting that there are other better first languages out there. As a recent college grad ('15), my intro course was in Python and then the next course was in C. Python was easy to jump into--it usually just made sense and worked. While learning about loops, lists, strings, etc, that was useful. Equally useful was then moving to C and getting a better understanding of the "lower level" (especially in the sophomore computer systems course). But you don't have to understand caches, page tables, and threading to jump into a first programming class and master the principles.
