SEEKING WORK • REMOTE ONLY
I'm data scientist (Python, Java, R) and a developer. Mainly I do stuff like web scraping, simulations, data wrangling, models and automation. I'm also interested in tech general. Currently playing with MeteorJS and learning about full stack JavaScript. I wouldn't mind working as a backend or fullstack developer either. Oh and I also have a masters in mathematical statistics if that's important. So to sum up I'm not afraid of: Python (strongest language), Java, R, JavaScript, CSS, HTML, Bootstrap, MeteorJS, C# and I have even published a native Android app. ;-)

A scientific conclusion does not become intrinsically less interesting just because all it took was a regression a first-year stats student could do. Simple and obvious is often better.

The suggestion in the linked article that, "hey, we ran a regression so now we can just come up with whatever interpretation we like" irked me as well, but you really do have to read the comments of the peer reviewers: one is peeved by the fact that they don't talk about his/her pet topic, another that they don't include this or that kind of historical context, another tries to be smart about statistical methodology but in the process shows their incompetence (a beta coefficient is a measure of effect size, you dummy)... when all the authors want to do is to point at the fact that opposition to pornography has declined over time. You can argue that this is not interesting, that this is obvious, but the whole point of science is to not accept things just because they seem obvious.

A new journal launched recently, by the way, which is aimed at exactly this sort of finding: https://sciencematters.io The idea is that scientists will be able to publish empirical results without the requirement to craft an entire story around it. Science needs theory but it also needs facts.

Indeed, some people are way more afraid of needles.

And the pain (for drilling+filling a regular cavity) really isn't that bad. The biggest unpleasantness about it is that it's in a weird place, at the back of my tooth, and that it happens at pretty much random intervals beyond my control. Most of the time you don't feel a thing, until the dentist "hits a nerve", sharp pain, but also subsides within the second.

And as far as I've understood they don't actually hit the nerve with the drill, just that the tooth locally heats up from the drill friction, which the nerve feels as a sharp pain, anyone know if that is actually right? I just ... read it somewhere :)

I used to do without (it wasn't offered, I was young and didn't ask either), but nowadays I usually opt for the anaesthetic, I don't mind needles at all, and there's no downside to it, afaik.
I suppose there's some type inference there and you'll get the default be 0 since 1 is also an integer, not a string.

Humans invest, computers trade. Its not about who is better at predicting. Most companies will gain value over time. There's no prediction to it. Algorithms are not predicting either. They are trying to fake out other algorithms and profit off of market inefficiencies. You don't need an algorithm, though, to buy something and then sell it six months later.

These sort of solutions (Wi-Fi and/or Bluetooth based) are already growing in popularity amongst the retail sector (esp. large shopping malls), so no surprise that an airport is doing likewise.

And to be clear, this in no way implies that I am okay with this state of affairs.

Postgres transactions can also take as long as they want and the results will never be inconsistent.

The downside to SERIALIZABLE is that conflicts become visible failures to the client, so you have to handle them and retry. Datomic solves this by serialising through the function you pass, but at great latency cost.

The worst thing about this trend is it also affects usability on websites that do provide sufficient (albeit subtle) cues.

It's like raising the general UX noise level from previous experiences which over time will train people not to trust their initial instincts.

You may want to take a closer look at the slides about what has been pledged so far. httpd, smtpd, ntpd, relayd, slowcgi, xterm... They're not quite emacs, but they're also not just command line tools.
My experience comes from an Ivy Bridge machine with a B75 chipset and 4 RAM slots, YMMV.

I had a single 2GB 1333MHz stick and bought another one second-hand. The sticks had different densities (one had 4 and the other 8 memory chips on) but timings were the same. The system would not boot with the sticks on the same bank (same slot color) but when I moved one stick to a different bank, the system booted and BIOS indicated the memory was operating in dual channel mode at correct timings. I didn't experience any issues with the system for 1 year.

If your machine only has two RAM slots with a single bank, then it's a crapshoot on whether the system will boot. With two different banks you can usually mix non-matching memory.
It's probably better to open the case, remove the ports, cut the traces, then re-seal the case with security screws and tamper resistant seals.

I'm gently worried about their design for production. That prototype PCB looks pretty tight for machine production.

Agreed, I'm more or less positive on the physical goods free-trade aspects of TPP but all of the copyright and IP law additions worry me.
I'm clueless about type theory, and outside school/university I've rearely used math on complicated stuff (mainly geometry in from-scratch GUIs) because creating mathematical models of real-world systems is very hard (in my opinion).

So I would say that modeling human personality would be an incredibly complex/non-liniar sort of thing.

I am quite fond of the Myers–Briggs Type Indicator, but I know it's controversial, and it only has 4 variables, I imagine a more comprehensive model would have many more variables.
Ask HN: Can I help you with data scraping?
I am a software developer from Ukraine, desperate for some extra income.

I have been freelancing on the side doing straightforward data scraping tasks. Think: download course topics, prices and ratings from a public courses website; download Amazon.com product data for a certain category; etc. Everything organized neatly in a CSV.  If you need this type of work done, I would love to work with you. The cost for a CSV of under ~100,000 records would be $50.

edit: Yeah, that article is not just misleading, it's constructed in a way that seems methodological enough to be concrete that it's dangerous. Different tools for different purposes, and he didn't even bother going to the vendor's own wiki to check for documentation. ugh.
Don't bother reading this rant below unless you want technical details, but that administrator misconfigured his VPN to the point where OVPN underperformed by four times what it should have been.

Its been ages since I played around with networking at a low-level (we're talking teenage years, when ARIN didn't charge for netblocks, and Cisco 7206VXR's could hold the entire internet BGP table in it), but I'll give it a go.

1) It's not a fair comparison to begin with since OpenVPN is effectively maintaining a lot more information as it's acting as either a) as is in his configuration, a Layer 3 router, there's bound to be more overhead as it's maintaining a lot more information than a single Point-to-Point SSH connection; he should be using Bridged Mode and routing via a virtual switch at L2 instead.[1] He sort of acknowledged this by making an appeal to the OSI layer, but then didn't check to see if there was a way to disable the full-routing functionality and move down to switching.

As he himself said, he's using this simply to tunnel peer-to-peer, so if he configures his subnet as a /30 on OpenVPN, defined static routes, and read this guide [2] he'd see that an MTU at ~6000 is recommended (jumbo frames indeed!). Starting with a similar config as his (using iperf), the OpenVPN guys went from ~125Mbps to ~500 mbps.

That was without kernel tuning, just parameter changing.

2) I haven't tested this, but if you read the comments within the thread (especially from those made by kasperd his networking device is misconfigured at the kernel level (for his purposes), leading to tons of fragmentation that can be rectified [see: the MTU/MSS discussion in the OP's "Read more comments"]. edit: Yep I was right. Check cite [2].

I'm sure someone who's actually in networking can address this further but this is not only apples-to-oranges but rotten-apples*-to-oranges. (where rotten-apples == a very poorly configured set of OpenVPN instances).

"Build your own digital library"?

For a single book, sure, makes sense, but this totally doesn't scale. Perhaps a nice gadget to have at a hackerspace, but then again you can probably just build this yourself.
A hard-to-remove sticker on the windshield for parking in the wrong place? Won't that guarantee that the car will be staying in that wrong place for a lot longer? It doesn't sound safe to drive with a sticker in the middle of your windscreen.

This is just plain destructive and counterproductive. Use something that's easily noticed but also easily removed.
- full screen pop-ups obscuring the entire article

- popups that obscure the article after you start reading and scroll down

- campaigns that follow you everywhere

- advertising in the middle of the text you're reading, in the same font as the article

- entire articles written simply to be able to place a product or an ad (advertorials)

- pages on which 50% or more is taken over by ads

and on and on.

Really the web of 2000 was so much more innocent in this respect. Those 640x480 ads were relatively easy to ignore, usually above the fold and maybe a skyscraper along the side but that was about it. Irritating, sure. But nothing compared to being hounded by ads for a specific product because you once googled a particular term or that feeling halfway through reading something that it is simply an un-declared ad.

Btw, I host a copy of geocities today and it is entirely ad free :)
Doesn't sound too far off from many Java jobs.
I was a tech recruiter for 9 years. Filled hundreds of tech jobs at startups. The only thing employers really care about is hiring employees that help the company do one of three things:

1. save time

2. save money

3. make money

No rational employer will look at a time saving, money saving, money making candidate and think "this person appears to be too good a match for my business needs".

Business value trumps ageism. Most the candidates I couldn't place typically didn't focus on trying to be profitable employees.
The article also conveniently overlooks the vast number of other certifications that Aeroman has to uphold, as if somehow the likes of EASA can't be trusted to inspect aircraft maintenance facilities. I'm even more perplexed by the evidence-free assumption that "private contractors in the US" (a designation which includes an awful lot of divisions of household-name conglomerates) must somehow have worse hiring practices than airline-owned maintenance divisions. And the rather odd categorisation of Singapore as in the "developing world", which it isn't by any definition of "developed country" that permits the designation to be applied to countries populated predominantly by non-white people...

All the statistical evidence points to air travel being safer than at any point in history but.... scary anecdotes and foreigners
> My mom has a foundry here in Slovenia and at some point she decided to outsource production of some relatively easy stuff to China, because it seemed cheaper. Well, suffice it to say she stopped after the first batch arrived, in which only about 30% of products were up to standards, which are easy to track in die casting: a few precise measurements and an X-ray, all totalling 5 minutes of work.

So your expectation is that you can do it cheaper elsewhere to the same level of quality? There is high quality manufacturing in China and many companies do that. You can't expect to the the level of quality you want sending some plans over to a remote country to a dumping price.

For how good Chinese manufacturing can be just look at your apple computer.
>The problem with copyright is that it is used as an excuse to deliver the good idea to protect the new authors who are still alive, in the same package with the bad idea to let unspecified number of loosely related and unrelated people feed off free money source created by long dead authors decades ago.

I think part of the idea is that whether the creators are dead or not, having copyright and "unrelated people feed off", still maintains an economy over the item and gives it monetary value. Whereas if it was de-copyrighted it would lose that value -- everybody could just copy it.

E.g. Disney only being able to create or allow the creation of Mickey Mouse stuff (t-shirts etc), leads to a large business for them, taxes for US etc. (Plus pays a lobby to ensure longer copyright). If Mickey Mouse was suddenly public domain, that would stop and its characters would be devalued very fast, with everybody competing with ever cheaper products with him on.
You can use used RAM just fine. Put it through a very thorough test before using the machine (and you should do that with new RAM just the same). And seeing new RAM fail within 90 days of purchase or so is not rare at all, even for very expensive brands. The risk is mostly in how you handle the modules, if you do that well and whoever removed it did that well too then there is no risk that you wouldn't have if you bought new.

The only reason you won't know about a lot of RAM failures is because ECC isn't as common as it should be.

Flagged for jumping to conclusions and not understanding the basic material in spite of being a self-declared professional in the field.
So maybe we should start randomizing MAC adresses whenever Wifi is turned on.

(Would it be a privacy problem if MAC adresses were very short-lived? I really don't know.)
> he dismisses SE Linux on that basis. I don't see why the same doesn't apply to pledge.

If you use a Linux distro that enables SE Linux, the second it gets in the way you can turn it off. If you install OpenBSD-current right now, all those utilities use pledge and you can't just turn it off.
It would put interesting spin on the second amendment fights though.

Well that's a relief. :)
TensorFlow looks amazing, and the Google team deserves huge kudos for open-sourcing it. It may well become one of the best supported OS DL frameworks out there.

People have been asking about its fundamental differentiators. I'm not sure there are any. Theano and Torch already set a pretty high standard.

We know what good tools look like, and those tools exist even if they're getting incremental improvements.

Now it's just a matter of building really cool things with them.

Not all science is theory-based. If biologists discover a new species, I sure hope they're not required to have a theory about why the species "has to exist"; even detailed descriptions and study of its habitat and organs can come later.

A job is a contract between two parties for a period of time. If you remove all kinds of unspoken expectations from employment, it would be a productive arrangement for the two parties. In a scarcity world me being an employee expects the employer to be more generous but when I have better opportunity, I am more likely to be not loyal to the company the same way a company replaces me with cheaper options. Employer needs good PR to be perceived in positive light and the employee has to meet the loyalty threshold to be hirable. The game gets more complex.

Turns out, humans prefer long term relationships when it comes to employers. Amazon is like a short term fling may be a 1 year stand. I doubt their retention is better than that. We will have to see the long term effects of this trend. I predict that if people perceive amazon as a short time gig, Amzn will have problem hiring anyone other than immigrants with visa regulation handcuffs.

>The problem with hard power is, that it is expensive.

Only for total enforcement, and only when the technology is not advanced enough to make even that cheap.

Here's a hypothetical example: with widespread internet surveillance, you could just charge people immediately on the first sign of them pirating something -- take the money off of their bank accounts/salary, kind of the same way one gets a traffic ticket through camera surveillance, but even faster.

>If it wasn't police states would work wonderfully.

Who said that they don't? It's often not the police state that fails, it is the state in general, and for other reasons.
> I don't see how pledge is different from Capsicum which he criticises on this basis, one it is compiled in you cant disable it.

This is addressed in the slides. Capsicum is 5 years old and used in 12 programs because it is difficult to implement. Pledge is 6 months old and used in over 400 programs already.
How will this work practically? Let's say we want to try this just for a month. Make a list of such companies and try not to spend our money with them. First of all, making this list itself isn't that simple, because of confusing and ever changing murky corporate structures (apps like buycott [1] can help here). In many industries, a handful of players control the entire market - just 3 or 4 companies control meat supply in the US, Monsanto controls a huge portion of seeds and so on. In the end we'll probably end up with a list of couple of dozen companies in our "bad list" and our options to shop (even the basic necessities) will be severely limited. Not saying it can't be done, it is just difficult to do it without some serious collective effort. It is definitely a good exercise to brainstorm ideas though, we gotta start somewhere.

The only big risk with new RAM is if it has a lower speed than the other RAM in your system, as (correct me if I'm wrong) that can slow down your other RAM modules.
Facebook's strategy here is to build an AI brand before they have the actual technology, which could make a lot of sense. At the same time the interactions between M's team and its users will provide meaningful data to train the AI on.
