Did my first root of Android phone. I had two Android phones before, but I never rooted it. This time I had a need for root to add the Chinese language to a Samsung Galaxy S3. The specific model is T-mobile SGH-T999 (shown in the Download or Recovery mode, but the model number on the settings says AT&T model number, which caused some issue for me later down the road).
The main reason for doing this is to add Chinese language support. It looks like by reading the article we can only get it work by rooting. I also looked at another article on the language support that suggested both MoreLocale2 and Language Enabler. Tried MoreLocale2 first but it seems needing root. So I started looked at the root tutorial. Because of the “wrong” model number, initially I thought this is an at&t device (model number at&t samsung galaxy s3 i9300, and here is an tutorial for that). Note the two tutorials are similar (t-mobile root tutorial here), the main difference is the at&t one is more verbose, and it has a link to the mod5 file for the at&t model. The odin program did not work for me initially because I was using the latter mod5 file (mismatch between hardware and mod5).
After that mistake the device was stuck in the Download mode (link to get into the Download mode), and could not reboot. I googled I have to download a Samsung software to get it restored. There were other hiccup too, one being the device cannot connect to my Windows 7 laptop (a bit old HP elite book), even after I install the driver. Had to reboot to make sure they connect. Back to topic, I was able to root after I switched to the mod5 file for t-mobile device. And it worked like a charm. After that I installed the rootCheck and SuperSu app from the Play store.
After the root, reboot I installed the Language Enabler app by Wanam from Google Play store (again refer to the language article above).
Final impression: the Samsung s3 is a relatively old device by today’s standard, but it works as a basic smartphone and adding the Chinese language to it, in my specific case, could potentially save an iPhone purchase (SE starts at about $400 in the states). It just takes some work to get it work, from enabling the developer mode/USB debugging on the device, to the odin software root.
I first learned the “production environment” in 2010, when I worked as contractor for a major railway company. Before that I was mostly in CAD software development and consulting environment the word “production” did not come often. To be precise at Siemens PLM/UGS as developers, we did have access to various production releases and did validation for bug and bug fixes from time to time. Our code goes to release per year or per quarter. But production is not as significant as the maintenance releases, so this is the world of shrink wrap (engineering) software world.
Came to the world of business applications, or web. The first thing I learned is it’s not a good idea for newbies to touch production data. Or for that matter, not good idea for devs to touch that either. Very few people has production access, besides admins (database, web), the few people have access are usually product owner, business analysts, or product support people. And fast forward 5, 6 years, I became one of the latter. This is a privilege. Something I learned over past year:
1) Start from baby steps: e. g., if we want to update 1000 records: start from one or two records, do the update, validate and if everything looks good, do the mass update. This goes th way of divide/conquer too: so for example, if I need to delete 3 or 4 million records in one script (one run), I know it will be a long operation, and I don’t want the operation hang or fail in the middle. So what do I do? I divide the deleting operation into a few, each operation deletes half a million, much more manageable, and I will get the it complete much faster or get feedback much faster.
A common question for software developer is to be an employee (full time, perm) or be an contractor (W-2, or 1099). Strictly speaking the 1099 is more like a small business, and I have not done it personally. I heard some experienced people did the 1099; I will share if I have that exp. down the road.
I spent most of my career so far being an employee (8 years for Siemens PLM/UGS was the longest); I also spent some time being an contractor (total 3 places, about 28 months). Each option has pros and cons. A few things I learned from my own exp.
1) People have all kinds of expectations for contractors, usually the higher pay, the higher the expectation. For employee, they are a bit more patient.
2) Contract to hire. I found this is usually promised or at least suggested at the beginning, as personally I still prefer to be employee long time. But in two cases, I found they were not the case. All types things happen at client, but in one case looking back I felt the client may never had intention to convert. So this is something to keep in mind as for some people the longevity/conversion is important factor.
Followed this instruction move away from bluehost; and move domain into godaddy. Most instructions are accurate, except one needs to ping pong couple times, started from bluehost first, then at godaddy website, after that I received email from godaddy asking about the transfer, go ahead and use the information in the email to start the official transfer, at last I go to bluehost website and approved the transfer. The interesting part is the entry of name server on my web host (digitalocean) gets updated automatically once I approved the transfer by clicking the link on bluehost. This really surprised me as I was expecting to make changes manually on my own
You may ask why I bother to transfer? I have actually moved my web hosting from bluehost to digitalocean (shared host to dedicated hosting) a while ago. This is the last step before moving completely away from the bluehost. No ill feeling towards bluehost (although couple years ago it did give me some headache). It’s just the cost between the two are comparable and I like to have more say on the web hosting.
Last but not least, if you have Amex card, check if you have the godaddy $20 off $50 offer. I found it from one of my Amex card, and I used it for domain transfer ($9.99 x 5 years plus a bit tax/fees). So the total will be about $30 after Amex offer.
I thought this problem for a while. Sometimes I heard people complained companies like Lego discriminate: their toys are more for boys than girls, so Lego came up this Lego friends series which is geared more toward girl, as they ranges from bakeries, beach house, to rain forest rescue, and they have a lot girl figures.
I think I fell into this trap too. I think some of the tech toys can be helpful and stimulate my daughter’s interest on STEM, but I did not follow through. She is 5 and will be 6 in a few months. So recently I did something different, I bought a quad copter (while she cannot play it, it could stimulate her interest), and the snap circuits 100. I can still sense her natural tendency is still social science, as I saw that’s her favorite in brain pop Jr. But I will give it some time and hopefully she will fall in love with IXL too
Another related topic is the “hour of code” initiative, I feel the awareness of coding or programming is reach all time high in school these days. Still remember my first computer program in basic language, when I was in middle school (about 13 or 14). Of course now we have so much wonderful material and resources such as Kahn academy, raspberry pi etc. It’s much more fun and hopefully can be integrated into science and math curriculum as well. Personally I think that’s more fun than standardized tests. Don’t get me wrong, I think fundamental training is still important, but creative work or education are also important. This takes time and effort, I am hoping more stakeholders (educators and parents) can buy into this in the future
It seems the wifi router comes with AT&T u-verse does not work with Apple TV. Apple TV could not find the wifi network from the build in u-verse wifi router. I found one workaround, that is to turn off the build in Wifi, use an old wifi router (D-Link DI-524) for Wifi instead. But there is still problem with the mirroring from iPad to Apple TV. Since I still have my previous LinkSys wrt54g router, I set it up as second router behind the DI-524, and connecting both the Apple TV and iPad to wrt54g. That worked. Another side benefits is wrt54g is a newer/more powerful router, and could broadcast wider range. So in a summary the architecture from internet to apple TV is something like below.
You may wonder why I add this extra D-Link DI-524 old router. The problem was I could not easily connect LinkSys wrt54g (the newer router) to u-verse modem. So I used the old router as a bridge. If someone has idea to make it work without this extra router, please let me know. (Email: minjie DOT xu AT gmail DOT com; or twitter @stlplace)
There is another problem with setup AT&T u-verse which is not related to Apple TV. The problem is when creating new account at their web site, they prompt for secret question/answer, it appears they don’t take any space in the answer. It was a programming error (web page text field validation) in my opinion, since I have done some web programming lately. The workaround is not to type any space. Simple enough.
This is also after using cable internet for about 8 or 9 years, I am switching to AT&T. I was using their DSL before switching to cable. The main reason is their service is cheaper, another factor is the cable had some connection issues lately.
(Update 05-07-2015) Came across this post regarding how to make direct connection from linksys wrt54gl to uverse router. I tried it but was not successful. It does not like the new local ip address 10.0.0.1 for linksys. But the theory there (conflicting local ip address between uverse and wrt54gl) seems holds, as I saw people discuss similar problem on linksys support forum.
One big complaints on the new iPad is its lack of multitasking support. From technical perspective, I think that’s because iPad will be use iPhone OS, currently at 3.2 beta, and it does not support multitasking. It does support iPod (listening to music) and another task such as browsing web though. Some developers speculate Apple will support multitask in its iPhone OS 4.0.
Oh well, my point here is not just about iPhone/iPad multitasking. My point is trying to discuss whether multitasking, work both for us human beings and for the computers (ultimately controlled by us and supposed to help us work more efficiently). To be honest I don’t have the answer. But I read one interesting article when I google “multitasking makes you stupid”. I did not intensionally typed in those words, it just stands out when I typed “multitasking” in my browser google toolbar (another one is multitasking myth). Anyway, here are an interesting article from the Atlantic (2007)
My logitech V200 mouse is more than 3 years old. Recently it acts a bit strange, basically the clicking does not work very well: for instance, when I intended clicking once, it will click twice, vice versa. So I was looking for a replacement for some time. I found the VX Nano is a good one.
