pkaeding··on Show HN: Pdf to json based on xpdf
I think you forgot the configure/make dance?
pkaeding··on Parse is shutting down today
And if I download the open source code, and run it on my own server, is it a service as a service as whatever-the-opposite-of-a-service is? I'm confused...
pkaeding··on Whiteboard sticker for your laptop
Yeah, it seems to trick the mechanism that detects the lid is closed. It took me a while to discover why my work laptop would go to sleep as I was typing, when I had it stacked on top of my (closed) personal laptop.
pkaeding··on China has wealth of data on what individuals are doing at a micro level
This could also be ad retargeting. You'll often see ads for things you looked at, but did not buy.
pkaeding··on Atlassian acquires Trello for $425M
More accurately, they merged Stash with Bitbucket (Stash is now called 'Bitbucket Server').
pkaeding··on Richard Feynman Put Himself on the FBI’s Do Not Call List
I'm not familiar with this particular case, but innocent people confess more frequently than you might think. Investigators put tremendous pressure on suspects during interrogation, and they can often feed details of the case to the suspect, resulting in a 'detailed confession'. Many times, the investigator is not intentionally trying to get a false confession.
pkaeding··on Basic Economy Fares Don't Lower Ticket Prices, They Increase Ticket Prices
My guess is that it wouldn't matter much, since accidents at intra-city speeds are rarely fatal.

Accidents on country roads are often fatal though, so maybe that is where the difference would come from (and country driving is not an alternative to flying commercial).

pkaeding··on Enter your address and find out everyone who represents you in U.S. government
Yeah, that might work, as a social engineering tactic to get out of a ticket.
pkaeding··on Amsterdam Introduces Contactless Payment Jackets for Beggars
I was thinking the same thing. This 'cashless society' is going a little too far, if you ask me.
pkaeding··on Enter your address and find out everyone who represents you in U.S. government
Good luck with that! The side of the road is no place for yelling at or threatening cops.
pkaeding··on Maslow's Hierarchy of Site Reliability Engineering Needs (2015)
I've modified the title to expand the acronym. Apologies for the confusion; I forgot that not everyone's head is where mine is. (I'm not the author of the article; I just found it interesting and wanted to share.)
pkaeding··on ‘Duck Dynasty’ vs. ‘Modern Family’: 50 Maps of the U.S. Cultural Divide
> That map, at least at first glance, makes Duck Dynasty look like a giant hit in Oregon

Well, it makes it look like a big hit in Harney County, OR, and a flop in Portland. Which appears to be accurate-- of the people in Harney County, lots of them watch Duck Dynasty. There isn't much fine print there.

pkaeding··on Do Teachers Need to Include the History of Mathematics in Their Teaching? (2003)
I'm not sure I agree. I think that understanding that knowledge is never done, and that science is about exploring new ideas and questioning our current understanding is much more important to the layperson than knowing how atoms are structured.

I also think that couching science as a journey--a mystery to be solved, with clues and red herrings along the way--will help to get students interested in learning the details. (This is all just my gut instinct; I have no experience in science education, so I might not know what I'm talking about).

pkaeding··on Do Teachers Need to Include the History of Mathematics in Their Teaching? (2003)
I think there is value in teaching that there have been prior models (but more energy should be spent on the current thinking) because it shows that good scientists are constantly researching and revising their ideas as they get more information. Science is never done.
pkaeding··on Offline First – A Better HTML5 User Experience
Yeah, that's true. JSON-patch won't help with all situations. It is still an under-utilized tool, IMO.
pkaeding··on Offline First – A Better HTML5 User Experience
JSON-Patch [1] can be helpful here. You can maintain a list of changes that need to be applied, such that they only touch the parts of the document that need to change (other changes to other parts can be interleaved). If necessary, you can include tests to assert that some value in the document is what you expect it should be, and the patch can be rejected if that test fails.

pkaeding··on LaunchDarkly gets $8.7M to put the right features in front of right users
There are a few open-source feature flag libraries out there, but what makes our service better (IMO) is mostly the cross-platform consistency (so a user will get the same value of a flag across different services, mobile, etc) and the ease with which non-technical people (eg product managers, etc) can adjust the targeting.

Of course, you should evaluate the options for your situation. For many use cases, an open source library will solve the problem just fine. For larger projects/teams, something like LaunchDarkly will be a better fit.

pkaeding··on LaunchDarkly gets $8.7M to put the right features in front of right users
We have mobile (iOS/Android) SDKs, so you can use LD for mobile apps as well, but the backend SDKs are primarily meant for SaaS-style server processes (where the SDK token can be guarded from users, and the process serves many different users, some of whom will get different flag values).

We have gotten some requests for desktop SDK support, which would work more like the mobile or JS clients work, since there is a single user at a time, and the key used to get flag values must not leak any proprietary business info or details about other users. This is on our roadmap, so the funding will help here :)

pkaeding··on LaunchDarkly gets $8.7M to put the right features in front of right users
As a matter of fact, we have experimented with multi-armed bandit 'auto-pilot' to roll out a new feature while watching A/B test results. I'd like to see this make it to production as well; it was one of those things that sounded like a fun idea, but we weren't sure if actual customers would use it :).

nb: I work for LaunchDarkly, if it wasn't obvious from my comment.

pkaeding··on Sharing National Security Letters with the Public
It is definitely true that many people believe Trump has fascist tendencies, but it is worth noting that many people believe HRC has similar tendencies, and would also greatly expand the surveillance state. Some of these two groups (who distrust each candidate) overlap, while many distrust one much more than the other.
pkaeding··on Hacker News Simulator
What is the story here? Are the comments generated by some clever Markov chain based on real HN comments? This looks like it might be an interesting weekend project; tell me more?
pkaeding··on Shazam Keeps Your Mac’s Microphone Always On, Even When You Turn It Off
Nope [1] is one pretty slick after-maket hardware 'switch' you can add to your webcam. Of course, some gaffer's tape works just as well, and costs a lot less (but doesn't look as slick). I don't have any such solution for the microphone, though.

pkaeding··on Webhook Tester
The full runscope product is really powerful too. I recommend anyone who does anything with HTTP add it to their toolbox. (I have no affiliation)
pkaeding··on Yahoo scanned customer emails for US intelligence
Yahoo was attributing its recently announced data breach to state-sponsored attackers.... Maybe that wasn't so far off the mark after all.
pkaeding··on An Important Message About Yahoo User Security
Right, but in this case, it does not require a password. So it is not two-factor.
pkaeding··on An Important Message About Yahoo User Security
Sorry, I misunderstood your statement. I thought you were comparing it to 2FA elsewhere. Now I see that you were just comparing it to the second factor elsewhere (not the whole 2FA0).
pkaeding··on An Important Message About Yahoo User Security
If you don't enter a password, then it isn't two factor auth at all. It just swapping one-factor (something you know) for another (something you have).
pkaeding··on The Python Paradox Is Now the Scala Paradox (2009)
Hey, I resemble that comment!

As someone with extensive experience in both Scala and Mongo, I agree. Mongo is nice for experiments that might go nowhere, but when you give it a real production workload, it falls apart fast.

pkaeding··on Teen Creates “Sit with Us” App for Bullied Kids
When I was growing up, my mom gave me the advice her dad had given her: you aren't allowed to start a fight, but you sure as hell can finish one.
pkaeding··on Pardon Snowden
I don't think they would have a problem with people signing this. It lets the people blow off steam with no real effect. Once you sign it, you think "well, I've done my part. I signed the online petition, and changed my Twitter/Facebook icon."
