ropeladder··on Ask HN: What do you love/hate about terminals? Would you change them?
This. I would love to be able to type "[command] --[tab]" and have it list all the options, and/or common options, so when I'm learning 'tar' I don't have to start typing, realize I've forgotten the command, and then have to go use man or --help or go Google it.
ropeladder··on Excel team considering Python as scripting language: asking for feedback
This would be great but it's a bit surprising given the move to add support for R in SQL server, Power BI, etc...
ropeladder··on Learn Anything White Paper
Thanks for the link. I'm using D3 + Vue.js, with D3 handling the data, layout and rendering, and then Vue (with Vuex) handling events and state management. I think this example is closer to what you are doing (but using Vue)? https://emiliorizzo.github.io/vue-d3-network/
ropeladder··on Learn Anything White Paper
Hey this looks really cool. Are you familiar with Metacademy? (https://metacademy.org/) (previously on HN: https://news.ycombinator.com/item?id=7617683) Looks like you are trying to do a very similar thing, although they are maybe operating on a more conceptual level.

What have you used to build the site and do the layout? I'm always interested in how people are using graph-based UIs since I've been working on one myself over at Thicket.io: https://thicket.io. (you can browse a graph of academic paper citations and then connect papers to policy arguments) It's a real challenge to display lots of information coherently.

ropeladder··on Introduction to R Programming
Anyone with a programming background getting into R should absolutely go read _Advanced R_. I've been using R off and on for a while now but Advanced R was a real revelation. All of R's weird behavior finally made sense.

Edit: Also there is a 2nd edition in the works: (confusingly hosted at the same subdomain of a different version of Hadley Wickham's website. https://adv-r.hadley.nz/

ropeladder··on CVS Is Said to Agree to Buy Aetna
The only real upside I see here is that, the more vertically and horizontally concentrated the private sector gets, the more absurd most arguments for privatized, profit-driven healthcare appear.

Basically every other developed country has shown that the government can do as good of a job at half the cost. Socialize it all.

ropeladder··on CVS Is Said to Agree to Buy Aetna
"the US funds over 50% of R&D for the entire world"

Not sure exactly what numbers you're basing that on, but I believe a significant portion of that research (especially basic level stuff) is government funded, which is not a good argument for allowing pharma companies to keep prices high.

ropeladder··on Firefox Private Browsing vs. Chrome Incognito: Which Is Faster?
You want the Multiple Tab Handler add-on for Firefox. It's 57 ready and even works with tree style tabs.
ropeladder··on Senators push to ditch social security numbers in light of Equifax hack
It's funny in light of all the "cars are freedom!" posts in the Bob Luntz post that is also up on the front page, but we DO effectively have a state-level ID system in the form of driver's licences.
ropeladder··on Show HN: Record Linkage Resources
Record linkage is conceptually pretty simple--it's just deduplicating records (usually of people, in census or medical or commercial or other scenarios) that don't have unique identifiers. It's tough because it's O(N^2) and because you're trying to build a bunch of disparate information into your matching decision.

It's helpful to hear how confusing it is. I stumbled around for literally years trying to build my own solution until finally a kind soul on the Data Science board on Stack Exchange directed me to the Record Linkage Wikipedia page, and I figured out some of the right terms to search for.

I'll try adding some more examples up top and use case scenarios up top.

I'm also hoping to add some info to help differentiate the software a bit more, but unfortunately most of them are barely past the proof-of-concept stage in terms of usability.

ropeladder··on Royalties from Writing a Hit Song with Justin Bieber
You are confusing "distribution" with "supply". Having lots of people making music is a different issue from having music freely available via youtube. Music has been pretty darn cheap to reproduce for decades.

Yes, availability of substitutes can diminish bargaining power of music rights holders, but I'm not convinced that's at all how we should interpret these numbers. I think this is more about market power and network effects of the middlemen (google, pandora, the labels, etc...)

I would be interested in the revenue split between rights holders and YouTube.

ropeladder··on Show HN: Dffer – Get notified when a website changes
Assuming this is reliable it would be great for job searches. (if you're targeting smaller organizations with static-enough job pages) Seems a bit expensive though--especially when I might rather sign up for, say, daily checks on up to 240 websites instead of hourly checks on 10 websites.
ropeladder··on PostgreSQL 10 Released
Just started writing it up! Thanks for the encouragement.
ropeladder··on PostgreSQL 10 Released
Just upgraded and it's been rocky so far. (I'll spare you the upgrade details, just make sure you don't try to upgrade using apt if you initially installed the enterprisedb.com bundle)

But now that I've got v10 running I'm unable to do a fairly simple CREATE TABLE command that worked fine in 9.6: it maxes out my RAM and my swap until the db crashes. (which never happened once in 9.6)

ropeladder··on Tree Style Tabs Extension Ported to Firefox 57
This is great news. I'm still worried about what will happen to my large Scrapbook[1] archive, though. Most of the useful things about that plugin (saving, browsing, and loading files on the local disk) are not available in the new APIs I think.

ropeladder··on Show HN: Readwise – Review and retain your Kindle highlights
Glad you are working on this! I've been pretty disappointed at how non-standardized highlights (and comments) are for ebooks. Taking notes, highlighting, and 'active reading' are generally worse on electronic platforms and the potential to be have easier access to my generated content initially seemed to compensate for that... until I realized that I couldn't sync it up at all and none of the formats seemed to be compatible.

That said, I have avoided Amazon entirely and am not particularly interested in the spaced repetition aspect so I won't be signing up just yet. Would love to hear if/when you support Calibre, Kobo, and/or Moon Reader.

ropeladder··on Angela Merkel’s record on environmental policy has been a disaster
Hitler was working hard on PR to keep the US out. Recent I saw a map the Nazis had made with the proportion of the population of German descent for each US state, created for propaganda purposes.
ropeladder··on Underestimating the power of Jeff Bezos
Amazon pulling advertising is scary but not entirely beyond the pale. I find the idea that authors are afraid to criticize Amazon to be much more worrisome: these days, writing a book is an important source of income for politicians, academics and many other import leaders. If none of these people are free to criticize one of the largest and most powerful business organizations in the country (and that business is an arbiter of what they choose to sell more broadly), that's a huge loss for democracy.
ropeladder··on Underestimating the power of Jeff Bezos
That is certainly a possible takeaway. My takeaway is that we shouldn't have one man's hand feeding everyone who contributes to the political and intellectual life of the country.
ropeladder··on Counterproductive effects of the commuter parking tax benefit
The article is arguing against government subsidies, not business choices. Businesses are providing a benefit, parking, that is not taxed as income. If that benefit was taxed in the same way income was, it would be more expensive for both businesses and consumers and therefore businesses and consumers might make other choices about transit (or location).

Further, I would argue that the time for your commute is to a large part determined by the available infrastructure (roads vs subway lines vs busses, for example), which is something the public has chosen to allocate funds for. There are certainly more and less efficient ways to move people around, and I'm not saying that cars are better or worse, just that the efficiency is partly a choice the public has made.

ropeladder··on GoboLinux: A distro that redefines the entire filesystem hierarchy
Coming from Windows a year or so ago, the Linux filesystem has been probably the most confusing thing about the switch (I've read about the logic behind /var and /bin and /usr several times but it was not intuitive to me and didn't stick). I generally have no idea where my config files are stored and can barely find where programs keep their data. And then I download some software that doesn't install itself and I have to figure out where to put it... The fact that this is all only sorta-kinda standardized between distributions, and that you often have separate config files for the system, for the user, and for the session doesn't help either.

It's not clear that GoboLinux entirely solves this issue but at first glance it looks like it's trying and the /Programs organization is pretty intuitive.

What's not appealing at all though is using a distro that doesn't have custom packages for all the software I'm using (aka is not Ubuntu or RedHat based). I'm not at all comfortable building from source--when I've tried it I've rarely been successful--and the prospect of further winnowing down my choices (from not just Linux-compatible software to software that however many GoboLinux users have uploaded to their Recipes directory) is, well, pretty intimidating.

ropeladder··on Ask HN: What Podcasts are you listening right now and why?
Reply all is funny and about the internet. The Dig is not funny or about startups but I just discovered it and wanted to share. Smart policy discussion with a lefty viewpoint.
ropeladder··on How Harvard Business School Has Reshaped American Capitalism
Whenever I hear critiques of MBAs I think of this anecdote from a paper [1] by Yanis Varoufakis:

In the parlance of signaling theory these [MBA] transcripts are known as screening devices. One personnel manager (of a financial services company) explained this to me candidly: “I have no doubt that economics courses, MBAs, etc. teach nothing I need my employees to know. If anything I need to reprogram them on the job. The courses they have taken encourage bad thinking.” “But then,” I asked, “why do you prefer to hire college graduates?” “Because,” he answered matter of factly, “if these kids were willing (and able) to pay large sums of money in fees; if they submitted boring assignment after boring assignment without fail, and did not complain vigorously in the process; then there is a good chance that they are the kind of people who will appeal to my customers and do as they are told.”

ropeladder··on Is Every Speed Limit Too Low?
That water screen is really brilliant.
ropeladder··on Ask HN: How did you acquire your first 100 users?
I'm right in a similar place with my own project* right now so thanks for asking your question.

I think you have may have a cool idea with pipecourses but honestly the main page doesn't provide enough info for me to tell. Mostly, I have no idea what a 'pipecourse' is and how it is supposed to work.

(As best I can understand, it's sort of like Medium or Google+ but designed for more granular following. It's not really clear what it means to follow experiences/ideas/etc... instead of people. Obviously it's still people writing things. Do you just follow tags that anyone can post to? Or if you follow a given 'pipecourse' how is that different from just following a blog on RSS?)

An easily discoverable 'What are pipecourses?' page would be really helpful. At the very least provide a little blurb up top explaining what it does and what makes it unique, and/or a few use cases. "Pipecourses is a blogging platform designed to give users more granular, topic-based control over what they post and follow. (plus a 1-sentence example use case)"

ropeladder··on Yale Climate Opinion Maps
It's D3 according to the source file; the type of map is called a 'choropleth'. Here is a tutorial that might be useful. (I haven't done this specific one but I've made similar stuff before.) http://www.cartographicperspectives.org/index.php/journal/ar...
ropeladder··on Wine Running on Windows with the Windows Subsystem for Linux
I had endless trouble getting my logitech wireless audio receiver to work in Windows 8 & 10. Works way better in Linux Mint (though it still forgets the pairing pretty often; but that's way less annoying than simply being unable to connect).
ropeladder··on India floats the idea of a universal basic income
"...and likely implementation."

It's true that you can make UBIs and NITs equivalent, but I think it's important to emphasize the implementation part: they are very unlikely to be implemented the same way. This is because, for them to be equivalent, you need the drop-off rate as incomes increase for an NIT to be equal to the increase in taxes on income earners below 2x the UBI level.

In other words, an NIT is likely to come with a high marginal "tax" (aka loss of NIT) rate for low earners, while a UBI is likely to keep marginal tax rates for low earners low.

ropeladder··on Ask HN: What device do you use to read academic papers with?
If you want to sync larger Zotero libraries for free between computers you can use SyncThing to sync the libraries and then let Zotero sync up the database. SyncThing isn't cloud based, so your machines have to be on at the same time, but otherwise it works great.

I posted instructions on the Zotero forums a while back: https://forums.zotero.org/discussion/50191/syncing-zotero-wi...

ropeladder··on Ventusky – Weather data visualization
After WeatherSpark shut down I spent a few minutes poking around weather data sources before getting overwhelmed and giving up. It looks like they get all their historical data from Weather.gov. (WeatherSpark lists their data sources here: https://weatherspark.com/about ...and weather.gov appears to have their data available for download from NOAA: https://www.ncdc.noaa.gov/)
