For those now wondering what their own uptime is (as did I), there's free Apps that can show you.
E.g. for iOS: https://itunes.apple.com/dk/app/mocha-isys/id326673288?mt=8 (not pretty but gets the job done);
For Android: https://play.google.com/store/apps/details?id=com.sysuptime.procomputation (haven't tried it).
Android Stability: Over 1000 Hours to Reboot
On my desktop PC I proud myself with only having to reboot perhaps once a week. While I consider this as a sign of operating system stability I recently noticed that I could not remember when I last rebooted my Android based smartphone. Even though I use a lot of apps such as the web browser, Goo...
Fair enough, turns out I was mixing up "Cloud" and "SaaS". Thanks for clarifying.
Calendar and Address Book Synchronization With Owncloud
No doubt, calendar and address book synchronization between PCs, smartphones and perhaps a web based interface is a convenient thing. However, so far I always stayed away from this as it meant handing over my data to a web based company. While I am sure that pretty much every online service has ...
Yes, for you and me and the rest of the tech-savvy web, this poses a big chance (either for transitioning to one's 'own "cloud"' or for new services to emerge, maybe with new/better features than Google Reader).
However, here's an interesting take from another angle:
http://macsparky.com/blog/2013/3/the-rss-apocalypse.
In a nutshell, it makes the point that *ordinary* people (aka 'the 95 percent') won't bother to actively transition to some other service, but rather call it quits with RSS and go somewhere else entirely.
This could upheave Facebook et al to replace RSS for this majority of users, entering a vicious cycle of shrinking demand and supply.
-> Let's hope for the best and expect the worst...
Bye Bye Google Reader - And Thanks For All The Fish
If you are reading blogs like mine via an RSS Feed Reader you've probably heard by now that Google wants to shut down their popular Google Reader in a couple of months. Being a Google Reader user myself I was disappointed at first because it is a great service, works well and using it is part of...
Yeah, you got the foul egg of AVM's support, there.
Of course, the company sanctioned way to deal with your problem would have been to make you go through repeated hardware swaps before finally up-selling you on their newest model, "that comes without such limitations". Hope you catch the sarcasm ;)
AVM Lets me Down With the Fritzbox
Back in December I was ecstatic when AVM released a new software version for my Fritzbox VDSL/Wi-Fi Router at home as they included a cloud file server system in the box that made it very easy to share large files with other people, which I sometimes do. And things worked pretty well for about ...
It seems with the below findings, Notebooks are the only safe place to put SSDs, for now:
https://www.usenix.org/system/files/conference/fast13/fast13-final80.pdf
[quote] Our experimental results reveal that thirteen out of the fifteen tested SSD devices exhibit surprising failure behaviors under power faults, including bit corruption, shorn writes, unserializable writes, meta- data corruption, and total device failure. [/quote]

SSD Lifetime Estimation And How Much I Write to Disk Per Day
One of the limitations of Solid State Drives is that the Flash cells can't be rewritten indefinitely. The cells on the SSD drive I recently bought can only be rewritten around 1000 times. That doesn't sound like much but wear leveling ensures that desktop users with normal use don't have to worr...
Effects on Standby time would be much more interesting.
Whenever you're using the device, you expect to see the battery go down and probably wouldn't notice (let alone mind) the faster drain during a voice call.
And for something completely different:

First Numbers on VoLTE Power Consumption
Light Reading has recently posted an interesting article on how much power Voice over LTE calls draw compared to circuit switched calls today from a smartphone battery. In the report, Metrica Wireless is quoted with a power consumption measurement of a VoLTE call of 1358 mW compared to 680 mW of...
The scenario described in the linked blog post occurred to me as the 21st-century equivalent to a coin super-glued to the pavement to make passers-by reach out for it, only to find it immovable...
How Does A Closed Femto Cell Reject Users?
Femto cells have been a buzzword for many years in the industry. They might now have been renamed into small cells but in most countries they are not (yet) used. One way to use a femto cell is to patch coverage holes in private homes. Here, it may makes sense to restrict the use of the femto to f...
How about the HTML5 player (youtube.com/html5)?
Also, would be interesting to see whether HTTP streaming (on mobile devices, e.g. iPhone) eases the encrypted distribution of streaming *content*.
Observation: Youtube Is Now HTTPS - But The Streams Are Not
When I watched a video on Youtube today I noticed that the page's URL was https://www.youtube.com.... Interesting, I thought, it's encrypted now! If the streams are encrytped too, that would have interesting implications for video caching and compression servers in some mobile networks as they w...
"Bad idea" in this case is a huge understatement. The only thing worse I can come up with would be to charge incoming calls, even if I don't answer..
Why Charging for Incoming SMS is a Bad Idea
Ever since the SMS service was launched back then in the mid 1990's, most users around the world only pay for SMS messages they are originating but not for SMS messages they receive. And that is a good thing as users don't have control over incoming SMS messages and whether they want to receive ...

Half The Phones Sold In Germany In 2012 Will be Smartphones
says Fritz Joussen, CEO of Vodafone Germany and president of Bitcom, a German telecom trade association. Last year it was already one third of all phones, which shows an interesting trend. While a few years ago a smartphone sold did not automatically also mean that a data connection came with it...
Maybe "trial" is the TelCo's "beta".
Similar stunts are pulled with "soft launches".
It just means: our hotline won't (or can't) help the customer if there are problems ;-)
LTE Trials and LTE Trials
Every couple of weeks I am hearing of a new LTE trial of one network operator or another and I am beginning to wonder what they are actually trialing or what the word "trial" actually means!? Two years ago, when first network operators in the Nordic European countries trialed LTE, it was unchart...
In my appartment, 2G and 3G is nearly unusable so I have to rely on WiFi for staying online (for conveniences such as push notifications).
Although I don't have WiFi reception problems per se, I recently had to adjust for what seems to be a new neighbor with high TX power. For a quick n dirty WiFi scan, this App for Android did better than I had expected: https://market.android.com/details?id=com.farproc.wifi.analyzer
Maybe this can cut it for your WiFi as well.
Cheers
Switching-Off Wi-Fi On My Smartphone At Home
An interesting reverse strategy happening at the moment on my smartphone: Instead of having Wi-Fi activated on my smartphone by default to benefit from cheap internet access at home and access to local resources I am rather opting now to have it switched-off by default unless I really need it, e...
Maybe Cox just realised they should have gone for a brand name that allows for fewer silly/childish word jokes from the start ;-)
The first thing that occured to me after reading was that DSL providers have the advantage that they can put their initial network invests in a small region and still thrive with a focus on quality because they simply know, where their customers are going to use the service (i.e. at the subscriber's site).
Mobile operators can't say "We cover $BIGCITY1 and $BIGCITY2 but nothing else (or maybe later)". In Germany, examples for such ISPs are HanseNet and NetCologne (even the names indicate that they have a narrow local focus).
A new mobile operator that just spent gazillions on network infrastructure simply would have to hit the ground running (in terms of customer base) to be profitable from the start. From my point of view, it's too hard a market to emerge in, I think.
Is The Age For New Wireless Network Operators Over?
Lightreading recently reported that US cable network operator Cox has given up its plans for wireless after having bought LTE spectrum for $550 million previously and launching as an MVNO on Sprint's network about a year ago. That was a short and costly trip to wireless land. It seems that it be...
IMHO the problem as described above (lack of cloud availability == no access to your data) is not with the "cloud" per se.
I'd like to point out the fundamental difference between using "the cloud" as "master" vs. "only" source of information.
"Cloud sync" services that only sync information between your devices (e.g. Dropbox, iCloud and even Google sync via Exchange) have the advantage that the information is *on all your device(s)* at any time (security matters aside). Of course, if the sync engine or DB gets corrupted, you may loose data anyway.
On the other hand, "Cloud only" services with the single purpose of delivering data in real time (e.g. Facebook stream, Twitter, Google+) depend more heavily on the availability of access (mobile broadband, server uptime).
Facebook Down And Why I Like To Have My Personal Data With Me
Here's an anecdote of something that recently happened to me which has some interesting insights into what's currently happening in mobile: During the day I got a call from a friend calling me in my role as a tech- and mobile-savy person. He tells me that he is somewhere in a city because he has...
I didn't read "Zero Day" (yet..) but from your post I take it that you would enjoy "Daemon" (http://www.amazon.com/Daemon-Daniel-Suarez/dp/B003L1ZXCU) and "Freedom(tm)" (http://www.amazon.de/Freedom-Daniel-Suarez/dp/1849161763), both by Daniel Suarez, very much as well.
Zero Day - A Novel
You might have noticed that every now and then I not only discuss mobile related things on the blog but also security related thoughts, which usually have a mobile edge as well. In that regard I very much enjoy listening to the weekly "Security Now" podcast with Steve Gibson and Leo Laporte whic...
shouldn't it read "a base station usually has three sectorized cells each covering 120 degrees"?
;-)
feature request: include gps position of cell changes. this could give you a better idea of the differences in density.
train spotting, plane spotting, cell spotting..
Cell Counting Excercise
Obviously the main feature of my first self written Android App is to do some drive testing to see how many cells are out there and how good the network coverage in general is on a particular stretch. So in the past couple of days I took my apps for drive testing to see how many cells cover my w...
Instead of messing with each and every Addon you wish to install, consider installing the "Firefox Nightly Tester Tools" (https://addons.mozilla.org/en-US/firefox/addon/nightly-tester-tools/). Once installed, you can easily surpress Firefox' version compatibility checking alltogether (about:config --> "nightly.disableCheckCompatibility" = false)
Your Favourite Add-On Doesn't Work With Firefox 4 Yet? Fix It Youself!
As expressed in a previous post I'm quite happy about the improvements of Firefox 4 even at the expense of not being able to run a few add-on's which have not yet been upgraded to run in this version. After a bit of research, however, I found out that what keeps add-on's from installing in FF 4 ...
It's not only about speed and RTT:

Verizon, LTE and Averages - But What About the Maximum Speed?
Here's an interesting report from PC World about this years state of mobile networks in the US with a bunch of measurements and comparisons of previous years. By and large, improvements are impressive but there are a number of things I haven't quite figured out. First, the round trip delay times...
Just a thought on the higher delays in comparison to Europe you mentioned:
Since PC World definitely would have measured End-to-End RTTs, maybe US Wireless Carrier's infrastructure that's necessary to enforce fair use policies, metered billing, lawful interception and whatnot is even more bloated than in Europe.
Also, maybe they already have some kind of Deep Packet Inspection in place and on every packet, a lookup in the whitelist tables has to be performed (whitelist currently might only contain "*/*" so every packet gets a 'do not inspect').
