sghi··on An opinionated view of the Tidyverse “dialect” of the R language
As someone who uses and teaches R extensively (and loves the tidyverse) the tidyverse is so much easier to teach to people without any programming experience and who have very little faith in their tech or maths skills (which was me as well).

The tidyverse just 'made sense' to me when I started using R for the first time a few years ago, and now I love using R and programming. On the other hand, some of my ex-classmates learnt base R (because that's what we were taught) and found it hard, didn't learn anything properly, and now still think R or other programming languages are opaque and hard.

I'm not particularly fussed if Statistics Profs prefer data.table to dplyr or base R to tidyr, I know what is easier to teach, understand and use for me and a lot of other ecology/bio students and people.

sghi··on Podcast Advertising: What We Learned
I'd always (and always do) google an advert rather than trying to remember the exact website anyway. If you search 'href sep' or 'hrefs seo' or even 'aref seo' it always still comes up as the first result for me.
sghi··on Bold personality makes domestic dogs in a shelter less vulnerable to disease
So this is the research area that I currently work in, albeit with a disease ecology perspective rather than a biochemistry one. I've had a quick read of it and and although it does seem to track other research that has been done ("Why are behavioral and immune traits linked?" by Lopes 2017 is a nice review) I'd love to see some power analyses - the sample size seems pretty small for something as complex as this question. The study I'm helping with now has a minimum sample size in the hundreds, for instance, for a broadly similar question. PCA-ing a few tests together is pretty common, but also comes with a lot of potential biases (see "Avoiding the misuse of BLUP in behavioural ecology" by Houslay and Wilson if anyone is interested!)
sghi··on The British amateur who debunked the mathematics of happiness (2014)
It's great that this has been picked up recently, it's something I've been following along with for a while. If anyone is interested, James Heathers runs a podcast called Everything Hertz (https://twitter.com/hertzpodcast) with Dan Quintana and Nick has been a guest on it - it's well worth listening to if you're interested in science full stop.

These guys aren't researchers in my area of interest but the topics they cover are interesting and done very entertainingly!

sghi··on Why Searching Through 500M Pwned Passwords Is So Quick
No, he worked for Pfizer - https://www.troyhunt.com/today-marks-two-important-milestone...
sghi··on Elsevier’s profits swell to more than £900M
Are you sure? I'm nearly certain that PLOS is a publisher that charges manuscript charges for OA papers - most do.
sghi··on Trial of a blood test that detects eight common forms of cancer
I'm pretty sure they would be able to - I worked with cancer trial data (just a student job, doing data entry) but all patients were completely anonymised to anyone working with the data but readily identifiable by a specific unique ID number, so higher-level trial managers and doctors could find patient information if needed.
sghi··on Even after cutting staff, SoundCloud only has enough money for 50 more days
I love Chance, but I can't imagine that he's got the net worth already himself to buy SoundCloud / make a meaningful investment - maybe he has contacts who do or could help an investment group, but I think it might be a bit fanciful to say that Chance by himself can save SoundCloud.

sghi··on Why People from Manchester Are Mancunians, Not Manchesterians
Never heard of any of them either - from the Midlands and used to travel around UK a lot for work and never heard anyone use them in any conversation.
sghi··on Microsoft is laying off thousands in a major global sales reorganization
They always seemed to have quite a lot of games testers there as well(used to recruit for contract MS workers for Reading and London)
sghi··on Causes of differences in model and satellite tropospheric warming rates
Not a huge amount of experience with models this big, but a common problem I see in Ecology is a bit of a misunderstanding of how models can be used - they're only really useful as a representation of what is going on and a way of trying to look at a few variables.

A lot of the time models are seen as a kind-of black box, where you stick data in and get the right data out - doesn't quite work that way!

sghi··on Wind turbines are neither clean nor green and they provide zero global energy
That is true, they do, but in the UK at least all new ones/sites do need full ecological impact assessments (there are various levels of assessment needed depending on habitat suitability) and hopefully there will be a lessening on the problem long-term - off-shore is the way to go, of course!

(I do/help with these assessments)

sghi··on The Guardian Pulls Out of Facebook’s Instant Articles and Apple News
I get why they've done it, and The Guardian is a site that I both contribute to and disable my ad-blocker for, but I will miss the speed at which the articles load on my ancient and rubbish phone.

I'd still rather support them though!

sghi··on Tell HN: Happy Festivus
I think you may be two days too late. But happy Festivus to you too - it isn't over until you've pinned me.
sghi··on Ash Trees Could Disappear
What I've seen and (briefly) read from this article seem to agree - as soon as the Emerald Ash Borer appears in the UK, it's game over for us. We've (UK) been suffering from ash dieback in a very large way, and although we seem to have got it under containment via selective killing/leaving to rot of certain trees we're very aware that a large proportion of our remaining Ash's could go very quickly. I know of a few people that have worked with trying to work with different lichen species that favour Ash trees and transplant them onto others with varying success - the same was tried with species that favoured Elm trees before they died back. It just seems a shame that there's not too much we can see to do about it. (This all comes from a UG perspective, albiet one with extensive lichen experience and some experience of conserving some of the oldest woodland in the UK, so other opinions very much welcomed!!)
sghi··on An alarming number of scientific papers contain Excel errors
Yeah, it's a lot of manual entering of data (eg finding abundance of certain species of lichens, and lat/long, then manually entering all data and exporting this as a csv either for heatmaps with GIS or for more stats analysis and the same with animal species abundance) so it's good to know I'm not missing something fairly obvious!
sghi··on An alarming number of scientific papers contain Excel errors
I'm an Ecology student, and the last few days there's been a lot of (justified) criticism of Excel. I use R and Python for data analysis, but a lot of what I do is gathering data, inputting into Excel and then exporting this as a CSV for use in R/Python for statistical analysis - are there any other tools that can replace Excel for this step?
sghi··on Deep learning is creating computer systems we don't fully understand
I thought the sirius cybernetics corporation already had something like that!
sghi··on Reasons not to use (i.e., be used by) Facebook
For that, I was under the assumption that the 'People you may know' on facebook was also who had been looking at you on Facebook, so the driver might have been looking you up.
sghi··on Microsoft is cutting free OneDrive storage from 15 to 5 GB
I was wondering if they're not actually using it as a cost saving exercise, but one to encourage people to pay up for the paid version.

I imagine there's a few people using between 5 and 15GB that before were on the free version but now would have to pay to carry on using it.

sghi··on Infinit announces Project Dropboxe
This is what they're (Infinit) are already doing, isn't it? I can see why they might be a little annoyed at the name Infinite, but it's not like infinite is an unreasonable name for Dropbox to pick for their project...
sghi··on Who's downloading pirated papers? Everyone
Just as an aside, you could try Zotero - I use it on my laptop and phone and it works pretty well for me. There is a dedicated app as well. https://www.zotero.org/
sghi··on F*** You, I Quit – Hiring Is Broken
I do agree with you on all the rest of the points, but just to say I started out in software and IT sales (but now much happier in a very different field) and I have absolutely been asked to both sell interviewers pens and random products and to have lots of imaginary phone conversations.

Funnily enough, anywhere that asked me to do that turned out to be a pretty rubbish place to work...

sghi··on Ask HN: Average Salary for PHP Dev in London?
That sounds about right - I used to (don't hate me) work in recruitment and £40-50k was about the top end of the range for PHP devs in London before people started moving into contracting. YMMV and I'm sure there's exceptions but it doesn't sound like you're too far off the mark
sghi··on Sugar tax surprise in U.K. budget, but growth forecasts cut
Yes, British teeth could be better but they're not actually as bad as people think - http://www.bmj.com/content/351/bmj.h6543.long shows on average in the US kids are missing more teeth than in the UK, for instance
sghi··on People in Sweden are hiding cash in their microwaves
Don't forget my home town - http://www.theguardian.com/media/2015/jan/18/fox-news-apolog...
sghi··on Google Is 2B Lines of Code, All in One Place
I believe that Facebook ran into problems scaling Git, outlined here - https://code.facebook.com/posts/218678814984400/scaling-merc...
sghi··on British tech workers get paid a lot less than Americans
Those numbers look quite a bit too high on the British side - apparently devs with "three years of experience will make an average of $77,508 (£50,540)" and I don't think I've ever seen jobs advertised at that level for less than 5/7 years experience in London, especially for permanent roles rather than contract.
sghi··on What’s really going on in a salary negotiation
As far as I've seen, all new employers (or at least the HR department) have required a P45 which includes all previous salary information - making it easy to see if you've been flexible with the truth. I've always gone with the advice of declining to say what you're earning and just explain what you're looking for.
sghi··on 'Nobody My Age Can Afford to Stay Here Forever'
I understand that is a possible option, but isn't the whole point of this that it's not feasible to live in the city? Being forced further out to commute is kind of the point.
