How do you usually handle imbalanced data? I've had some success with SMOTE or weighted loss for imbalanced datasets, but I'm embarrassed to say I've been using AUC with ROC curves as the default - if this gives inferior model selection than AUC with PR curve I'll have to start doing that instead.
> Even more, do we stop the news from talking about it because doesn't the media coverage of suicide also increase suicides?

Responsible media already is careful about how they discuss suicide for exactly this reason.

One of the major problems with the series is that the people behind it did not understand the area they were venturing into. They thought that creating a topic for discussion was helpful. They were wrong, and by what I read, could not understand why. They did not listen to experts in the area for how to do that responsibly.
It serves as a very interesting test, either for those who want to limit some rights for safety reasons who fail to apply that logic here or for those who want to limit suicide as a topic for safety reasons but fail to apply it to other rights.
That's crazy. Like the architect scene from The Matrix Reloaded
Well then stop drinking with kids and go get some responsibilities. Be the one that drops off the heavy drinking train.
This makes sense to me from my experience. When I was around 18 a lot of people told stories of all the drinking (and sex) they did. I felt quite some pressure to drink more because of that.

Later I found out that a lot of these stories were vastly exaggerated. It's pretty sad that people feel the need to brag about destructive behavior like doing but that's the way it is.
I've literally no idea what the second paragraph means but I suspect it's quite important. Could you point to an example of this being done? Thanks.

While the film's subject matter is certainly intense, I had a positive take-away from it as well, which is that a large percentage of people who experience a failed suicide attempt are glad they failed. This was the logic used to justify constructing suicide prevention barriers on bridges. If you take away the immediate opportunity for people to take their own lives, a few determined people may find another way, but many more will give up their attempt.

Surprisingly, STEM helped the North win the Civil War [0].

One of the big differences at the time was the use of "repeaters" by the North. Having a gun that can shoot again quickly when the other side cannot is a huge advantage.

With the North winning the Civil War, they put both Reconstruction and the 15th Amendment in place, causing Blacks to have the right to vote (of course many people tried to thwart that law for almost a century).

There are always potential issues when a machine learning algorithm is applied over time.

Example #1: Let's say that cancer rates are increasing over time and cameras are improving over time. You might end up with a weird artifact in your model that higher resolution images are more likely to indicate cancer.

Example #2: Let's say that cancer-detecting algorithms are widely successful and so someone makes an app that lets you upload images of skin and the app tells you the probability of you having cancer. Suddenly a model that was trained on suspicious lesions is being used on normal freckles that people uploaded for fun. You end up with a lot of false positives. Maybe you try to combat that by including images uploaded to the app (that you somehow obtain labels for). But now you have a model that predicts that photos taken in brightly lit medical offices are likely to be cancer and blurry images taken in bathroom mirrors are not cancer.

You could argue that Example #2 is more about the difference between training data and data to be scored, but the fact remains that outside of tightly controlled scenarios, the way data is collected nearly always changes in time and ends up affecting model performance in unexpected ways.

Yes, I run it several times, but each time the effect wasn't noticeably better. And I would prefer to have an option for an explicit configuration of the rendering properties (like "hinting: slight/medium/none") instead of going through a series of sample screens, because this is getting really tiresome after a few passes...

I recently switched to a 4K/24" monitor and I actually cannot say that the Windows fonts are pixelated, but they are still too thin. And the larger fonts don't look good - as if the hinting was completely disabled for them.
Yes, that's true. The larger point, which I have not been able to successfully convey to you is that any venture can be made to look great when you get the pick the metrics of success.

Specifically newer MacBook Pros are having issues driving multiple (or in my case even a single external display).

most of the criticism i've heard about 13 reasons why is less that it portrays a 'taboo subject,' but rather that it does so in a way that glamorizes suicide.

from some perspectives, hannah got everything she wanted by killing herself. she got attention to her case and revenge on the people who mistreated her - and the show portrays that she wouldn't be able to achieve that if she hadn't committed suicide.

not everyone sees the series that way, of course. but for a certain subset of people - often young people who are bullied and neglected, who feel victimized by the world but helpless about it - it's very easy to interpret the series into 'suicide is how i win.'

For typical apps I think that Django is far superior to Flask because every Flask project ends up recreating a lot of Django's core functionality; but in a more time consuming and less standardized way.

Disclaimer: I do not believe that people should attempt to defeat hardware protection mechanisms with the intent to pirate software or defraud hardware manufacturer(s) in any way.

That being said, this article is a goldmine of information for people that are in the following categories:

1) Want to understand their hardware better;

2) Want to design their own hardware and/or protection mechanisms;

3) Want to bypass protection mechanisms on hardware they own / have paid for, for the purpose of learning more about that hardware and/or ethically running custom modifications or software;

I post the link to this article for the above group of people only; that is, ethical hackers and hardware enthusiasts.

This is about building a cross-platform infrastructure that would sit below things like csound, Faust, and many other similar front-ends, and allow them to emit code that'd run optimally on hardware platforms other than just a desktop CPU, to get better latency and performance.

I'm not going to address "listened to," because that is limited to one medium. But we have learned that even when people may have had suicide ideation for some time, the actual decision to do it is often an impulsive act. So their state of mind immediately leading up to an attempt is relevant.

Nobody can drive perfectly with .01 second precision at all times.

When Your Amazon Purchase Explodes
I think the issue is diversification. Carrying the note for a buyer can be a decent idea for a developer who owns 100 properties, but probably not if the loan represents 50% of your assets. Calculations like "risk adjusted return" start to fall apart when you get out of continuous statistics and into single-event probabilities ...
I applaud them. Reseller middlemen buying up the releases so they can profit are awful and inhibiting that activity is a greater good for society. In the ideal world sneakers could only be sold at retail, let the people who actually want to wear them buy them.
> While the London Bombing suspects were identified

They were identified. After they’d blown themselves up on trains and a bus. The one person ‘identified’ as it was happening was in fact mistakenly identified and killed by the police.

Surveillance only helps in situations like this where the authorities have intelligence upfront. Even then you can argue that regular on-foot surveillance is a more proportionate approach over serveilling the entire nation ‘just in case’.

I was in London when the bombs went off (I worked on Russel Square along from the bus bomb - I would walk past the site, every day, to and from work; and have a friend who was on the train going from Liverpool St that was blown up). And, I remember being nearby (and hearing) the IRA bomb in Bishopsgate. I still believe very strongly that governments should not have carte blanche rights to spy on all citizens.

As humans, we are really good at clinging onto things that support what we want to believe and forgetting about the things that oppose our beliefs. You see this today: if someone you know does something bad, you are very likely to say "that's just one thing, overall they're a good person". It's the same with religion and politics, you have to have a very open mind to accept new information that may change your beliefs, often it's easier to just let the information slip in one ear and out the other and continue with your daily life.

Someone already thinking about suicide or depression might watch the show (first season, maybe the second as well) and see that suicide is a viable option, and the potential benefits you get for executing it (leaving your mark on the world, leaving behind your story, etc).

Someone depressed, but -not- thinking about self-harm will see how accurate it is and will be able to identify with it, as with you and a few friends I know that have watched it. I had no idea these friends I've had for years were depressed until they watched the show, so it did bring positive change to their lives.

I've been using lingq.com for about two months to learn Japanese, and I think it's lightyears beyond any of the other tools I've used, which include Duolingo, Anki, japaneselevelup, and probably a few others I've forgotten. I've made more progress in two months than in my previous 12-18 months of (somewhat sporadic) study. I think the fundamental reason is that rather than doing some second-order activity like studying flashcards, lingq has you spending most of your time listening and reading.

Lingq is based on the idea of input-based learning, which I would summarize as "Read, listen, and stop worrying." This approach has a lot of research to support it (search for Stephen Krashen if you want to learn more about the research), and it is also the approach used by some famous hyper-polyglots like Kato Lomb, as well as Steve Kaufmann, the founder of lingq.

There are two main tools in lingq: One, an assisted reader which displays foreign language text, with words color-coded to indicate they are known by you, previously seen by you, or brand new. Looking up a word and storing a definition takes only a few clicks, so you can rapidly get through texts that would otherwise take forever. Even looking up a word in an online dictionary is 10x slower than doing it in lingq. The other tool is the playlist, which you can use to easily listen to the accompanying audio for a text you are studying on your phone.

By going back and forth between studying the written text, and then listening to the corresponding audio over and over and over (which is easy to do during dead time like driving, doing dishes, etc), I've vastly improved my listening comprehension and vocabulary compared to any other approach I've tried. I'm still far from fluent, but I'm convinced this is how I'll get there.

lingq's language courses also included 50-60 "mini-stories" depending on the language, which expose you to a _lot_ of different grammar and vocabulary. Once you get beyond those, the idea is to start importing native content from podcasts, articles, etc into the app. There is also a big library of content that other users have imported.

lingq does have a built-in SRS system but its sort of an afterthought, and I haven't found it very useful.

There are a lot of rough edges in the content and the website and phone app, including UI issues, flaky speech-to-text, incorrect word segmentation in the reader, bad definitions, and even grammatical mistakes in some of their original content. Ultimately I haven't found any of these to be a big hinderance.

I have no affiliation at all with lingq although I realize that my glowing review probably sounds like I'm astroturfing. It is a paid service ($10/month) but I've found it to be worth it many times over.
It's actually illegal for a shop CCTV system to cover the pavement outside, for example.

Do you have a source for that, please? I've been wondering about this kind of issue for a long time, as a lot of private premises now have cameras obviously overlooking public space outside or even more private areas like the gardens of neighbouring properties. Personally I find that quite intrusive in terms of the public spaces and rather inappropriate in terms of neighbouring private spaces, but given the many ambiguities in our data protection and privacy laws, it's not obvious to me what would make it illegal in black and white. Both the UK government web site and the ICO do have specific guidance about domestic CCTV systems that clearly allows the possibility of and provides guidance for systems that overlook areas outside the operator's own property.

Also, there is a huge amount of legacy code flying around. Write the fixed form parser as soon as you can.

I largely feel the same... unfortunately today too many have lost the appreciation for civil rights, including discourse and challenge. People don't want to hear opposing views and are even starting to conflate speech to violence/assault. This viewpoint can make censorship an appealing idea.

The reality is that censoring speech only serves not to alienate people, but to bring more aggression as those targeted not only feel oppressed, but are oppressed. And now instead of having counter views to challenge their own are driven into echo chambers of those with same-think.

I'm not just talking governments, but of Twitter, Facebook and others. In the end, it's best to challenge ideas with countering ideas. It's best to not conflate a person's views on a given subject with their whole. There's too much tribalism and identitarianism. Censorship and encroachment on traditional liberties seems to be ever expanding, and only serving to escalate what appears to be an inevitable crisis ahead in society.

I should probably clarify that it's actually the main way to get an interview (not hired) - you still have to pass whatever the interview tests are and a referral doesn't really help you there.

It's one of the main benefits of living in the bay area, you build out a network of friends working at different companies which adds a layer of job security and ability to interview more easily at interesting places.

Doesn't this somewhat conflict with the idea that companies who pay local rates are going to discriminate against people who live in higher cost-of-living areas? Because if that's true, then yeah you could try to game the system by asking for a SF based salary, but the trade-off is that now you're less competitive.
