yoda_sl··on Why don’t podcasts use VBR MP3s? Because iOS and macOS don’t accurately seek them
This in reference to Apple internal bug tracking system named "Radar", the number listed here is the bug ID and only Apple folks and probably the person that created that bug in the Radar system can see it

yoda_sl··on Jason: Scriptable iOS JSON Client
In a past project, we had a similar system used where most of the UI of the iOS app was driven by json served by the server. You can definitely do a lot, but the syntax of json had quite some limitation especially when you are trying to code some complex UI actions or add some business logic linked to your dynamic UI.

The system did evolve into using a combination of json and JS using for back then the newly introduced framework JavaScriptCore ... It made everything a lot easier overall since JS is definitely a proper language.

The JS obviously was able to map to native objects and thus performance overall was great. The app is still used by millions of users daily.

Edit: typo and adding more info

yoda_sl··on OxyContin's 12-hour problem
Heart rate and blood pressure will probably work in case of extreme pain/high level of pain. I am recovering from a 2 hours and half+ surgery on my ankle which was badly damaged: the surgery did require 2 experienced surgeons. The day post surgery my pain level was shooting to the roof even if I had a pain pump, the pain level was extreme -turn out that the pain pump was busted and was not working. At one time I decided to check my blood pressure and monitor my heart beat during a cycle of pain and yes it was definitely noticeable on the blood pressure, but slightly less on heart beat.
yoda_sl··on Facebook Reports Q1 2016 Results and Announces Proposal for New Class of Stock
That's what it looks like based on the latest post from: http://newsroom.fb.com/news/2016/04/marknote/

It's interesting that FB will be initiating dividends - I am no expert when companies usually start offering dividends but I was under the impression it's usually further in time when companies have been in business for a while. FB is still growing a lot so I am surprised - but again no expert in that.

yoda_sl··on Facebook Reports Q1 2016 Results and Announces Proposal for New Class of Stock
Some interesting numbers from the press release:

  Daily active users (DAUs) - DAUs were 1.09 billion on average for March 2016, an increase of 16% year-over-year.

  Mobile DAUs - Mobile DAUs were 989 million on average for March 2016, an increase of 24% year-over-year.

  Monthly active users (MAUs) - MAUs were 1.65 billion as of March 31, 2016, an increase of 15% year-over-year.

  Mobile MAUs - Mobile MAUs were 1.51 billion as of March 31, 2016, an increase of 21% year-over-year.

Revenue at $5.2B compared to $3.3B for last year quarter.
yoda_sl··on iPhone Sales Drop, and Apple’s 13-Year Surge Ebbs
The key numbers from the Press Release: The Company posted quarterly revenue of $50.6 billion and quarterly net income of $10.5 billion, or $1.90 per diluted share. These results compare to revenue of $58 billion and net income of $13.6 billion, or $2.33 per diluted share, in the year-ago quarter. Gross margin was 39.4 percent compared to 40.8 percent in the year-ago quarter. International sales accounted for 67 percent of the quarter’s revenue.

So not really a surprise from what they announced at previous quarter.

yoda_sl··on Withings acquired by Nokia
The acquisition price is apparently around $191M USD (€170M):

  http://www.digitaltrends.com/mobile/nokia-withings-acquisition-news/
I am overall happy with Withings products: wifi scale, step counter and blood pressure. My hope is that Nokia will be doing a better job with the acquisition than how they kept up with smartphones.

The purchase price seems to be on the low end; Withings do have a lot of personal customers info related to health and activities so I was thinking an acquisition price will be higher.

yoda_sl··on SpaceX Launch Livestream: CRS-8 Dragon Hosted Webcast
Wow! Mind blowing stuff today
yoda_sl··on A smart plug to monitor your router and automatically reset power if WiFi fails
Something I need to try... I haven't yet dig into all the wonders of the Pi gpio and that sounds like a fun project.
yoda_sl··on A smart plug to monitor your router and automatically reset power if WiFi fails
See my other post where I am using my Pi and reset my Wemo... Initially I was going the route to reboot the modem through the web interface until I noticed my stupid modem doesn't offer such option in the web interface! Since I had a spare Wemo Plug I was not using for a while I used that instead.
yoda_sl··on A smart plug to monitor your router and automatically reset power if WiFi fails
Interesting to see that. It turns out that around a month ago after seeing the Raspberry Pi project that send a tweet to Comcast when internet connection is slow, it gave me the motivation to use my Raspberry Pi 2 to do the following:

A- every 15 minutes check my internet connection: connectivity (reaching Goodle DNS host),

B- if connectivity fail, execute D-2 below, if not see next step below

C- then use SpeedTest download / upload; if download/upload speed are too slow then attempt a second test 30 seconds later

D- if the second attempt fail again then:

1- send an SMS with Twilio to my cell phone to let me know the modem will reboot, and wait 10 seconds

2- issue a "off" command to my Belkin Wemo (cable modem plugged into it), then wait another 30 seconds and issue a "on" command

On top of that I have installed InfluxDB + Grafana on my Pi so I can log the connection latency to Google DNS, and the download/upload speed. Example:

https://imgur.com/gallery/dgeFR

The Belkin Wemo command do use only my local Wifi, so even if the modem is down since my Pi is on the same LAN it can control the Wemo without problem.

It was a fun little project for my Pi. All written in Python. If anyone interested I can probably post the code somewhere.

yoda_sl··on Amazon’s Echo Brims with Groundbreaking Promise
As of the latest iPhone 6, you don't even need to have the iPhone plugged. You trained Siri a few times by saying a few sentences and later you can say "hey Siri" and it will start listening. Apple added some new chip which will be listening for that key sentence and will only react to your voice, not someone else. So no more funny joke from co-worker nor Podcast and in addition low battery impact.
yoda_sl··on Ask HN: In a difficult situation at work. Need advice
Sorry to hear about the project heading in the wrong direction beside your attempts. As many suggested sooner or later things are going to blow up and you need to either be prepared to face the storm since you are acting as a team lead, or simply either move to another group in the company or find a new place by sending your resume around. When it is going to blow up, and if you are still there I will advise you to keep track of any emails that you may have sent and shared in larger group with your concerns. Being able to show some accounting of what happened may help you overall.

Personally I will get the hell out of there: it is not worst wasting your time, energy and stress level especially considering what they are doing to your review. Working in a toxic environment is not good in the long term.

yoda_sl··on How I found one of the earliest browsers on a NeXTcube
> and it never was important until he got excited about WebOjects at Apple.

Not sure exactly what you mean by that since WebObjects was created at NeXT way before Steve was back at Apple. In fact before the acquisition Steve was the main WebObjects promoter so way before being back at Apple. True at Apple, Steve did continue to promote WebObjects internally for a couple years but afterwards he moved on.

yoda_sl··on Netflix Switch – dim lights, turn on the TV, order food, and silence your phone
Most likely the initial prototype was done during an hacktaton... I remember many years back someone that came up with a small TV on a toaster so we could say you can watch Netflix on your toaster, later on that toaster made it into a T-Shirt for the next hackaton!
yoda_sl··on The Rise of Voice Interfaces
Amazon Exho/Alexa is doing overall a good job in my house. Yes technicality it can listen to every words we say at home, but until now it didn't bother me much. I found out recently one guy that had the time to get Amazon Alexa SDK / voices to work in conjunction with my Nest thermostat and recently SmartThings did integrate with the Echo too. So it is now extremely convenient for asking Alexa to set the temperature by voice without the need to lookup for my phone or tablet, same in the evening to simply turn on the lights in a few places. I do think that Voice Control in home automation is going to be a big plus.

yoda_sl··on Ask HN: Open source OCR library?
Tesseract is quite good and can get some really good results if you can train it. I just wish there was a more UI friendly way for generating the training file; for the project where I had to use it I ended up paying a freelancer with some strong knowledge of Tesseract training. Really happy with the results for my iOS app (universal app)
yoda_sl··on Apple now rejecting apps with Pebble Smartwatch support
I do have myself a Pebble and honestly I find my Pebble apps in the Pebble store... Not looking in the Apple App Store
yoda_sl··on Apple now rejecting apps with Pebble Smartwatch support
The OP title is " Apple now rejecting apps with Pebble Smartwatch support" Sorry but no Apple is not rejecting such apps... It just doesn't want other product name mentioned. And yes Apple is the gatekeeper of the Apple ecosystem... It is just the way it is. I am not saying that what Apple is doing is right, but the OP statement is wrong
yoda_sl··on Apple now rejecting apps with Pebble Smartwatch support
Oh yes totally agreeing on that... I am not sure how many reviewers they have and some are more lenient whereas others are not... Trying to fight Apple here on simple words is a lost battle, and if they really care about getting their app to their users, the solution is a no brainer: edit the app description, save! Wait for approval, then done. It is only a metadata rejection and those are the one that are usually the easiest to fix
yoda_sl··on Apple now rejecting apps with Pebble Smartwatch support
Not sure what really is the big deal here... Apple had I think such requirements for not mentioning any other products or even mentioning pricing in your product description aka "On sale today only for $0.99" will get the same rejection... It is ok to put a %

So this is nothing new and just one Apple employee/reviewers that follow the rules from the guidelines... If the folks that were submitting the app try to resubmit and remove references of Pebble, most likely their app will be approved without problems.

Since their issue is with the app description, it is simply a metadata rejection of the app, and the developer do not even need to submit a new binary: just edit the app description and problem solved...

It shouldn't even made it in the top HN stories IMHO

yoda_sl··on UW scientists, biotech firm may have cure for colorblindness
I think SJ because of his cancer started to look closer at that industry... I will not be surprised that Tim Cook because of Steve's passing started to look too in that area and the Watch is just the first small attempt by Apple to enter in that space. Tim and Steve were close friends, and Tim being too an avid cyclist, morning gym has no problem to have a few Engineers and R&D spent in that area.
yoda_sl··on UW scientists, biotech firm may have cure for colorblindness
I am colorblind, and I have heard too about Enchroma... I do think that I have no issue trying out a pair of glasses and see the difference rather than betting on an injection in my eye... Don't take me wrong, I truly believe that some technical advances in medicine are welcome and needed, but colorblind is not a huge disability. I have learn to live with it, and it is not the end of the world. It is great if it works, but I think colorblindness isn't a first category Medical issue to be solved now.
yoda_sl··on How Life360 won against patent troll
I am glad you were able to get the proper verdict. Do you think that AGIS will try to come again after your company or rather stay away from you guys? do you think other trolls like AGIS may decide to avoid Life360 from now on due to this victory?
yoda_sl··on Introducing Pebble Time
I have to admit they did a good job with the new watch, adding color is great and still having the week of battery is huge. I was one of the early supporter for the first Pebble and have zero regret. It did convinced me of how useful a smart watch can be. I will be a little bit sad when replacing it with the Apple Watch when it comes out: I decided to change ship, but the Pebble will always have a special spot.

It's great to see they have a strong supporter base, and that will force Apple and others to stay active and compete.

I will for sure miss the long lasting battery of my Pebble!

yoda_sl··on Nest Protect is a terrible buggy product
It is only required when I used it remotely... Manual works even with internet down
yoda_sl··on Nest Protect is a terrible buggy product
Here is my personal experience with Nest Products overall:

- Own 3 thermostats: 1 at home and 2 at my wife Business

- 6 Nest Protect spread in different part of our home (aka master bedroom, hallway, kitchen,...)

The thermostats work fine and usually the only issues I have encountered were with Comcast or AT&T (wife Business) going down and the thermostat not every time able to reconnect automatically... Not a huge deal and overall happy with those. And checking our bills, over time I see some savings in electricity cost... And the big big plus is really being able to trigger the A/C during the summer hot days when our dogs are staying home, and we are not with them.

The Protect overall have been working as expected with the one in the kitchen kicking in often when we are cooking (previous smoke detectors in the kitchen have been doing the same so no surprise). At installation time one of the unit couldn't register, and after reaching out to Customer support got a replacement unit quickly which worked fine. 3 weeks ago out of the blue the Nest Protect in our master bed room started to do exactly the same thing as shown in the video but the alarm after a minute will end and the app was reporting the level of smoke going down... Except there was never any smoke at all... Since it did happen 3 days in a row and on the third day, I was there to witness it, I tried a few things without luck... Ended up removing the battery and again contacted a Nest support (glad that I know a few folks there so I didn't have to go to any phone diagnosis), and 2 days later got a replacement unit. Installed since then and problem didn't happen and the bad unit was returned.

My conclusion: the thermostat is almost rock solid except for flaky internet and doesn't always reconnect. The Protect are definitely more a v1 with still some glitch but still happy customer. I am not a huge fan that Google did acquire Nest and still have preferred Apple but I don't have too many complaints.

I do have too a bunch of Dropcam and again not really happy that they ended under Google control, but their camera are good.
