Nokia N950: How to Open the Back Cover


Thurs 07.19.12 – Yesterday my Nokia N950 dev testing phone decided to lose all charge after only 4 hours and I knew that it was time for a new battery. With some Twitter advice from Attila and Thomas, I was able to unscrew the back case batteries, open the back of the N950 from the speaker end and then verify which battery was in my device and at what mAh.
While the Nokia N950 specs as listed on the Maemo.org wiki state that the battery is the BL-4D 1320mAh, @achipa wrote that the Nokia 808 PureView’s BV-4D battery would work as well, which I tested and it worked. As of today on Amazon.com, the BL-4D is for sale but is only 1200mAh and the PureView’s BV-4D with 1400mAh is not yet available in the US or for sale on Amazon. When the BV-4D does come available I will get one for my N950 as the extra 200mAh will help in the battery lasting longer department.
Big Thanks to Attila and Thomas for their Twitter advice, esp. on how to do the Quick Charge (carry an extra battery and swap it out).

Yahoo + Marissa Mayer = A Good Thing

Today’s good news came at 1:16pm PDT when Marissa Mayer announced that she was leaving Google to join Yahoo as their new CEO.
I am greatly heartened by this.
I don’t think all cars should be designed and made in Detroit. I don’t think all movies should be written and filmed in Mumbai. I really don’t think all software and/or hardware should only be designed by Apple and Google (or in another era Microsoft & Apple, or IBM & …).
The more strong international and big national software, hardware, web, and mobile companies that there are, is for the better for everyone who uses said technologies.
The tech press loves to have a duopoly that they can pit against each other to the exclusion of all other companies, but as a user of technology I don’t want a binary either or choice. Life is richer when there is more than two choices, and it is much richer when there are more choices.
Yahoo, while it has been floundering in recent years, has been a company that still has great potential and many of non-tech folk I know use it every day. I look forward to seeing what Ms. Mayer will do, as her work and accomplishments preceed her, hopefully she will be able to refine Yahoo and help lead the company to focus on a place(s) of strength for the enrichment of all who use the web.

A Few Sunday Thoughts: Auto-Focus Lens Calibration and ComicCon

I am in the last month of finishing up my apps and my blogging has fallen into a deep crevasse since April. I suck. Go look at my Flickr or Twitter for visual and textual updates. Will resume normal service once my apps are submitted.
In the meantime, a couple of thoughts from the weekend:
1) Auto-Focus Lens Calibration: Ever since I bought my Nikon D800 and a few new lenses, I have been surprised how my cheap, $120 nifty fifty Nikon 50mm 1.8D lens has repeatedly shot great, sharp photos but that my ‘good’, expensive lenses have been a little soft in their focus.
Last week over at The Mansurov’s photography, Bob V blogged on “Nikon D800 – Cavier, Sardines, or … Spam?“, of which I am not experiencing a soft left focus on my Nikon D800 but the article did bring to my attention that one could purchase a Datacolor Spyder LensCal and calibrate one’s lenses at home.
That is what I did today, as the Datacolor Spyder LensCal (link includes a how-to video) arrived on Friday afternoon. As I expected, my Nikon 50mm 1.8D lens was pretty close to spot on with only a tiny bit of Auto-Focus fine tuning needed (-2), but my other lenses needed between -4 and -12 in fine tuning their focus. I was very pleased with the sharpness of focus that my Nikon 17-35mm f2.8 lens was able to achieve after calibration, but my 50mm 1.4G and 85mm 1.8D remained a bit soft even with calibration and the 85mm has a chromatic aberration issue.
I will not bore you with the tiny details or with the photos that I took to complete the calibration, but I need to do some research to see if the 85mm 1.8D lens is known to have a color shift or does the lens need to go to Nikon servicing.
2) While I am a Sci-Fi/Fantasy book fan and have been so since my late childhood/early teens, I am not a big comic book person nor do I watch TV or Sci-Fi movies. When I first heard of ComicCon and found out that it was not for Sci-Fi book readers also but for comics and film fans, I was a bit sad but happy for my friends who do love comics and film to have their own Con to go to. Other than a few dips into Pern and Discworld Muus and Mudds in the early 90s, I have not found myself involved in any fanfiction, roleplaying, and Con worlds. I spent most of the 90s and early 2000s heavily immersed in music worlds.
Thus when I get asked every year around this time if I am going to ComicCon and I demure, I usually get nods from my friends who are vets of the Con and bewildered expressions from folks who only know about it from the evening news. The second group usually says, “But you like weird hair and dress, you are artsy, AND you are a geek, shouldn’t you go?”
I will leave it for my friends for whom it is the highlight of their year.
