Alcatroz Xplorer Go! 100BT and Rapoo 8000s keyboard review

Recently I got myself two keyboards, the Alcatroz Xplorer GO! 100BT (Bluetooth) and the Rapoo 8000s dual keyboard mouse combo nano wireless. With this review hopefully would help anyone out there who may be planning between a bluetooth type devices and wireless type devices.

While waiting out during this Covid-19 virus lockdown and working from home, I went ahead and purchase th Alcatroz Xplorer Go! 100BT keyboard thinking that it might a good idea to use bluetooth to connect to my PC and other devices without having to sacrifice a USB port, especially on my laptop where there is a limited number of slots available. However after using it for awhile, this didn't turn out to be such a good idea, plus this keyboard design was not going the way that I've planned out.

Celcom XPAX Prepaid SIM card must be upgraded to get 3G

I decided to pop in to a Celcom centre to try to find out why my XPAX 24 could only get 2G/EDGE internet data. A quick check with my phone number and it showed up in their terminal that my SIM card was only meant to be used as 2G.

I found it odd that the Celcom shop was selling 2G XPAX prepaid card when everyone else, Maxis, DiGi, etc were selling 3G enabled prepaid SIM cards. It seems like Celcom stock is slower moving compared with the other telcos. In order to have 3G/HSPA+ internet data connection, I need to change and upgrade my SIM card to a 3G version. And the shop that sold it to me didn't even informed me about it! And when I called up Celcom support sometime back, they were just as befuddle and didn't understand what was my problem. Why is it Celcom support so poor? Anyway,...

Nested Cloud Storage and NTFS Symbolic Link

Having a bunch of free cloud storage from the likes of Google Drive, SkyDrive, Dropbox, Box.com and many others, you could embark on a synchronization strategy to back up to your precious files up in the cloud and even give you a convenience or two.

Scrounging around the internet I found you could do some rather interesting sync and backup using the cloud storage on offer.

As of this writing, I have:

Google Drive = 15GB variable with email storage
SkyDrive = 7GB plus a free 1 year 20GB storage for being a Windows Phone user
DropBox = 2GB, can be bump up by doing various task, and recently a link from my mobile Samsung Note 2 gave me a bonus 48GB storage for two years!
Box.com = 10GB
Ubuntu One = 5GB
Amazon = 5GB
Apple iCloud = 5GB

Surprise! Google Drive Storage is now 15GB

This came a surprise to me when I found that I have 15 GB free Google Drive storage. However after digging around the information online and on closer inspection of my account, this was not really an increase but rather a combining of storage from the various storage. Some blogs said the Drive storage account was increased because it felt like you gained 15 GB of Google Drive / Picasa storage and 15 GB of Gmail storage. So let's look at this closer.

LiveScribe distributor Big'Ant in Malaysia is no more

Talk about bad timing! Big Ant (M) Sdn Bhd under the K-One Technology Berhad who was authorized distributor of Livescribe Pulse and Echo digital pen products has gone bust! Just at the time when my 2GB Pulse pen just ran out of ink and I thought of buying a refill ink cartridge.

I found it strange when my usual IT haunt at All IT Section 14 PJ suddenly removed all the Livescribe products. At first nobody seemed to know what was happening and they weren't able to sell me any of the accessories and replacements. So I searched online and obtained the contact number for K-One Technology / Big’Ant division. Called them up but nobody picked up the phone. After several futile attempts, it dawned onto me that this company may have gone bankrupt.

DNS Servers in Malaysia and Overseas

Every now and then, I would tinker with my router modem and network adapters. In most cases DHCP would be fine. But some of the legacy devices like my very old HP Laser Jet 5000 series printer as well as our re-cond all-in-on Ricoh photocopier machine (although fairly new, but uses some very old network communication protocols) worked better with a fixed network IP protocol.

For small office like mine, manually configuring each PC to a fixed IP was not such a big issue. However when setting the Internet Protocol TCP/IPv4 from DHCP to manual settings, the "obtain DNS servers address automatically" sections gets grayed out.

So I would need to key in the DNS servers manually in order for internet connection to work. Scrounging around the internet, I managed to gather all the local DNS Servers as well as some international ones too! I set up this list because I can't remember the DNS server address, so this post was made as sort of a note for me for quick access!

Device failure one after another! Must be Murphy's Law

Just my luck, I got several electronic device failure one after another. Must be Murphy's Law at work here! First after a battery change, my wife Toyota Wish car remote control didn't work. The Toyota service people should have known better than to change the car remote batteries. Now it needs to be reset in order to work. That's probably minor compared to my car remote when I accidentaly shorted my Toyota Altis car remote while changing the broken casing. Should not have used a screwdriver to pry out the electronics. Now it doesn't work anymore. Next was the old HP fax printer, the modem was strucked by lightning long time ago but still could be used for printing and scanning. While trying to print some documents, the roller was making a ruckus, and finally I got ink cartridge error. I could try buying a new ink cartridge since the current one was already very low on ink anyway. After giving it some thought better not. It could be more than just a faulty cartride because the roller was making such awful noise. Besides ink catridge are expensive and I would have wasted money if the HP printer would not print. So that' the end of life for this HP printer. And finally the church PC which I was attempting to reinstall Windows XP. Well some people weren't too keen on using Ubuntu Linux though it would be far more virus resistant than Microsoft Windows. So I got down planning to dual boot it. The partitoning went fine without a hitch. Installing Windows XP was a different story. First round I got boot error. Strange, tried reinstalling a second time and the PC just hung after the initial booting diagnostic start up screen. Tried several reboot still got the same "hanging there not going anywhere" leaving me scratching my head. It could be the BIOS going crazy on me. For now the PC is not working. If the BIOS goes, the motherboard is just another dead wood. Schucks! And this good old Pentium 4 Intel 3GHz with an Intel 915GEV motherboard is a rather good piece of hardware. I should know, I picked the parts myself when I bought it in 2005. But now it no longer works. Argh! Looks like I will need some replacement hardware starting with a new printer like this Epson Stylus T13. Oh, well.

Fixing my Intel D915 GEV computer system

Spend the better part of my late nights fixing up the good old Intel D915 GEV motherboard PC. Apparently the hard drive died causing the whole system to freeze up. Hard drive kaput means just change the dead drive without having to purchase the entire PC system, because if the motherboard died, it would be a major replacement. Unfortunately due to the flooding in Bangkok, Western Digital plant is underwater, and that plant account for 50% of the world's hard drive supply.

Which means there is a shortage of hard drive in the market driving up the prices 100% or more! When last I check some vendors are selling at double and some at triple the price! And in All IT Digital Mall section 14 PJ, much to my indignation the sales guy didn't even want to sell to me and was reluctant to give me any price indication!

I'm not going to spend that money yet until Bangkok recovers and Western Digital production is back online. Fortunately I still got an old 40GB PATA IDE WD 7200rpm drive. Well it won't be as fast as a SATA drive, but it will have to do for now.

Default Cluster Size for NTFS, FAT32, exFAT

I needed to reformat my SanDisk 16GB USB flash drive to NTFS file format as I wanted to transfer a large 9++ GB movie file to view it on my media player box. So when the format dialog box came up, I was wondering what would be the best default cluster size for NTFS and what did the "default allocation size" meant.

 

Although I would like to keep my thumbdrive in its default format of FAT32, it was not able to handle any files larger than 4 GB. NTFS filesystem although has more features (encryption, compression, ownership, etc.), it would also mean using up more computer resource in Windows when processing files. Hence I still prefer the simpler FAT 32 drive format, but I have no choice here as the file size was greater than 4 GB. (Note: exFAT or extended FAT can store files larger than 4GB but this disk format is not supported by many media boxes, unfortunately! It was introduced to overcome the 4GB limit but due to lack of support from many devices, access to the files would be limited to Windows Vista/7 onwards.)

Streamyx is absolutely bad today!

It's been a week long and Streamyx is still trying to fix its server or junction box or whatever. The connection is intermittent and if I do connect, is absolutely horrendously slow! Sent from Yahoo! Mail on Android

[update 13/10/11]

How is one suppose to work if streamyx slows down to a crawl every few days? And this is definitely got nothing to do with the damaged undersea cable to the USA. Even accessing local website and data is so, so, so slow! Thumbs down yet again for streamyx. I think there is too many problems with streamyx for the month of October.

be weary of email misinformation

Friends and contacts and mean well when they pass you bits and pieces of trivia via email. Unfortunately some of those information is more like misinformation. I don't know why some people got so much time in their hands to concoct such fallacies, incorrect understanding as well as myths and urban legends. And once it was let loose into the wild wide world of web, it will become viral and spreads.

 

The thing is, some of this bits of misinformation seemed plausible. Especially if you don't have the background academic knowledge or remembering a partial bit of information that you may have studied a long time ago but then you forget and when you receive the email, the explanation seem rather possible because your memory was a bit hazy on that subject matter. This brings to mind the show, "Are you better than a fifth grade" reality show. And yes, we don't have perfect memory, and things that we studied at one time is gone with the wind after many years of not referencing it in our brain.

 

Although for me, I still have good recollection of some of things that I have studied especially on those subject matters that I liked (but unfortunately for me, I don't know why I'm so poor at remembering names with people that I met! Must be the way my brain is differently wired). Anyway, we don't all have that good memory and we use whatever means to memorized information be they important or trivia.

 

So whenever I receive emails about some interesting discovery, trivia, and even warnings, it is best to do a little research online to find out just how accurate those information. Some people just have too much time in their hands, and will take real information and give it a little twist. So when you receive it, the information seems correct at first glance, but in reality it is already in error due to bad interpretation or overly simplistic view or misunderstood or could even be a joke or malicious intent of creating disinformation.

 

Thank goodness for sites like Snopes, BreakTheChain and various website and individuals trying to debunked bad information. Yes, internet communication (websites and emails) may be the best thing that has happened because it provide vast information for your research and reading at the touch of the button. And yet there are also sites or individuals whose grasp of their subject matter that may be less than well researched or poorly understood or just plainly made wrong intentionally to create disinformation.

 

So while you are surfing around or receiving emails with those pieces of trivia, do be weary of misinformation. Don't be lazy, but do a little bit of research and find out its accuracy before passing it along to your friends and family. Perhaps you might learn a thing or two about the subject matter that was circulating in the wild and avoid the disinformation and to inform the sender that the information they are sending should be more accurate so that they won't learn the wrong thing and pass bad information around.

 

 

 

 

 

iPhone IOS 4 update is a pain

Updating iPhone IOS 4 to the latest version is really a big headache! Why can't Apple provide a separate file download? Why must it go through the iTunes 10 software for update? Mind you the file size is really huge at 666.6 MB (uh, the number of the beast too?) that's about the size of a CD-ROM. I know, I know, it takes me just as much trouble to download the 700 MB Ubuntu Linux ISO file, but I can use those helpful download software like uGet to continue my download if the connection breaks and also split my downloads to a couple of days if the server is really slow.

 

 

And this Apple update server is indeed really crawling at a snails pace! Could be Streamyx throttling my speed due to large download file. Or perhaps both, a slow server from Apple plus Streamyx broadband throttle, now that would really make your download day a super slow event. Wish they have a separate file for download. That would really make things it easier. I wonder why they don't do that? Perhaps they are afraid hackers would get at their code and reverse engineer it?

 

Whatever the reason, it makes for a poor user experience. That's why I don't always want to update my phone software, be it Apple's iPhone or Google's Android. Fortunately the Android update was far more faster, took me only about an hour plus for the update to be done.

 

However, my wife complained that the Apple iPhone was getting cranky and according to her fellow iPhone users in her office, that the mobile phone needs an update to make more stable. Her colleague left the phone overnight with the PC to download the update. Uh, with 666 MB and a slow server and broadband throttling, I guess that's the way to go about it.

Otherwise to keep your sanity the other option is to bring it over to the Telco (after all they bundled the phone in the mobile phone plan package) for the update since they have far more faster connection and perhaps even have the software at hand or they simply just have ultra fast broadband connection without being throttled.  

 

Anyway, I'm going to give this self-updating of Apple iPhone IOS 4 a go before crying surrender if it fails. Anything for dear wife!

 

 

Digital Pen Livescribe 2GB Echo now at MYR399

Prices are coming down, the digital pen Livescribe 2GB Echo model has drop to MYR399. Ouch! If I have known I would have waited instead. I bought my 2GB Pulse model some 3 months back.

So what's the difference?

The new Echo model has new features, it is more ergonomic and rubber grip. That should help ease my aching hand from prolong usage.

And it uses a cable rather than a dongle, so you can use it like a mosue while connected to your PC.
And they not round like a cylinder so it won't roll off your table.

These are little extras. Initially they were marketing it for MYR699. That price too steep lah. Now at MYR399 then more reasonable. If between Pulse vs Echo at same price, then Echo is the better choice.
Well, too late now. Will just have to make do with my Livescribe 2GB Pulse digital pen instead of the improve 2GB Echo version

Bypassing DNS Block of TM Streamyx

Recently I noticed there was lag whenever I tried to access internet. I guess the recent government directive to Streamyx and other ISP providers in Malaysia in an attempt to use DNS block has resulted in a slower internet access. Such DNS blocking is futile as it was very easy to bypass DNS block.

The Malaysian government went against their promise (perhaps even illegal since it went against the MSC Malaysia Bill of Guarantee) of giving its citizen unrestricted access to the internet and instructed Malaysian Communication and Multimedia Commission (MCMC) to block off certain sites. So much for freedom of information. The reasoning behind it was to fight against piracy and against illegal file sharing sites. That’s the overt reasoning, I should think there is also a covert conspiracy to also shut off opposition website as well too since they did get a hammering during the 2008 general election as the opposition used the internet media to voice out their opinion thus making the current coalition losing so many Parliament seats that they are now so desperate to get back their 2/3 majority.

Firefox 5 breaks Google Toolbar

The latest Firefox 5 update inadvertently broke the Google Toolbar. Frankly the version 5 came too fast in the wake of Firefox 4 which broke the Delicious bookmarking plugin.

Since I have several PC's, looks like i'm not going to update the rest of my PC's to Firefox 5 until Google comes up with an updated plugin.

--- [update 27/6/2011]

Found this thread in Mozilla support. By using this compatibility reporter extension, you could make Google Toolbar to work with Firefox 5. I gave it a try and it works! It also made my Trend Micro toolbar working in Firefox 5 too! Nice fix!

And finally I gave the Delicious toolbar a go too, and voila! It works! No need to wait for update from Delicious. Anyway, with the breaking of Delicious I found a better bookmarking service from Xmarks.com. Since I still got many bookmarks in Delicious, I guess I will be keeping both service for now.

The Google Toolbar 7.1.20110512W version works in Firefox 5.0 by using the Compatibility Reporter extension.

New devices for my PC hobby

Seems like i'm having a shopping spree on my IT gadget devices recently. Although Malaysia is having sales everywhere in the shopping malls. The same cannot be applied for computer gadgets.

With rather limited time, I haven't gotten around to blog about my new found gadgets.

Basically, i bought myself a LiveScribe 2GB Pulse smartpen as they were letting go at RM400 which was within grasp for me to give this smartpen a go. This model may not be new, but still works just as good.

I've also upgraded my modem coz my old wireless-B router already knocked out sometime ago and i was mulling whether to get the Belkin share router modem. But when Aztech recent lauch their new router modem wifi-N with a usb port for NAS, it was 1/2 the price of Belkin, at RM149, so I went for it.

And finally, I couldn't wait any longer and decided to iindulge myself with the SanDisk Cruzer 32 GB. I could only get it from PineApple computer store meeting up with old friends. I use to patronize their shop however their prices are not as competitive against the Low Yatt based shops in Digital Mall. Still they gave me a reasonable price. Which wasn't too bad.

Now preparing it for security and perhaps even install Ubuntu Linux into this thumbdrive since it got quite a lot of space!

HP OfficeJet warranty exchange problem

I was very pleased when my defective HP OfficeJet all in one printer fax scanner was given a one-to-one exchange. But my joy was shortlived after receiving the replacement unit. I don't know whether this was a slip up from the HP warranty service department. I don't know why they gave me a defective unit as replacement, in fact this unit was much worst off then my earlier OfficeJet.

Although my ealier unit could not get a dial tone,it could still print and scan. The replacement unit was a total wipeout. It kept giving me a paper jam message when i haven't even fed any paper. My guess the previous owner was a having a seroius paper jam defective unit. The HP service department didn't do a good job with the repair and they release the unit?

Very poor show on their part. Coz it left me with a poor impression about Hewlett-Packard. In their attempt to discourage people from submitting their defective HP units for warranty claim (they want to charge me $30 for checking a unit stillwithin warranty!) and made me call for phone support and yet they gave me a defective replacement! I was thinking how they could give customers brand new unit, but actually they are just giving reconditioned units which were defective and send it by the previous owner.

Sigh! No choice but to call them again to give me another replacement OfficeJet for the defective replacement OfficeJet that was for my earlier defective OfficeJet.

If the next unit is also defective, it would really show Hewlett-Packard having a very poor on their after sales service.

In fact I'm thinking twice about purchasing HP products in future. In their attempt to cut cost to improve their short term bottomline they are sacrificing their long term goodwill of their customers.  

Got My HP OfficeJet J3508 All-in-one Fax Scanner Printer

Got my HP officejet J3508 all-in-one fax scanner printer

Just my luck. My 3 year old HP all-in-one fax printer went kaput and I had to get replacement. Opted for HP Officejet J3508 all-in-one fax scanner printer.

This one uses black ink cartridge 702 only. That's all I need as I basically use it for faxing mainly with occassional document printing.

The colour print version, the J3608 is more expensive though it has a higher print speed of 20ppm vs 15ppm for the cheaper model. That's ok for me, no need so expensive. Besides my soho home business is still in the early stages. So not expecting any heavy fax volume.

My old HP officejet all-in-one could still print and scan though. Looks like it will just end up as printer only. I think I'll just place that in my in laws place wher a printer is required.

This HP Officejet J3508 is sufficient at least for now.

HP OfficeJet Warranty Exchange Problem

[update] Aug 2012

My good old HP all-in-one finally went kaput in my in-law's house, instead of getting another HP printer, decided to replace with a simple Epson desktop printer. Simple printing was all I needed in the other house.

As for my current house HP J3508, decided to not leave it on all day long due to lightning strikes. I have lost several surge protectors and it was very inconvenient when the surge protector failed to prevent damage to the fax printer itself. Though fortunately HP replaced a another set with no question asked. But it was not a brand new fax machine, just a repaired version from another user who had a problem with it. I found another solution to my personal fax requirement and that was to subscribe to a virtual fax service. It wasn't so cheap, but it was very convenient and less problematic.

Recently my work place 8 year old Panasonic Laser Fax was not working well. It could not feed in the paper for outgoing fax. Although it was an expensive fax, I thought it was not value for money for the repair. The fax toner was expensive plus every 4 toner changed, the laser drum need to replace and it wasn't cheap!

Nowadays people tended to scan into a PDF file and email over, so the amount of receiving fax was less. So opted to get the cheaper HP J3608 fax printer. It was simple and lightweight (the Panasonic fax was heavy!) and good enough for our simple daily usage. I couldn't find the black ink cartridge version only HP J3508 anymore. Perhaps it was so low priced (I bought the J3508 for RM200) or perhaps not popular, the vendor decided to sell the colour printer version instead (the J3608 was RM270). Since most incoming faxes would be black, the colour cartridge would definitely be under used and become unusable come the expiry date. No matter, the fax machine would still run without the colour cartridge, and if truly needed, it would be cheaper to replace it when compared with Panasonic toners and drum.

The only disadvantage I see is the HP inkjet printout would smear when come into contact with water. So if our hands were wet or sweaty, the fax copy would smear. This incident would not be common so I guess it would still be acceptable.

Changing to HTC Desire Z - thinking

I'm considering to change my android phone Sony Xperia X10 mini pro to HTC Desire Z. Sure I've just updated the firmware for this X10 and i liked the new updated stuffs. But there is still one drawback: the tiny fonts. At my age a larger font would go easier on my eyes especially since i do a lot of texting and mobile blogging. I couldn't find the font size adjustment in this Xperia and many of the rich text mail has extra tiny fonts. Fortunately the road sync has very nice comfortable fonts but it only allow one email account though. So my next best option is to plough in some dough perhaps trade in or sell my Xperia X10 and upgrade to HTC Desire Z. I know HTC got font sie adjustment base on my short lived experience of using HTC Wildfire. So it is just a matter of time for me to change my mobile phone.

Faulty Kingston DT mini 10 USB drive

Looks like it was just pure bad luck when I redeemed the Kingston DataTraveler mini 10 USB thumb drive from Bonuslink. I redeemed two DTmini 10 8GB thumbdrive, one for me, and one for my sister-in-law. I was fortunate that mine had no issues at all and currently now using it to store my MP3 to be played in my car's Red Fox MP3 FM Modulator player. My sis-in-law on the other hand seemed to get into the 5%-10% fault range of most defective digital device. Just a matter of probability, a 50-50 chance between mine and hers and of course a 5-10% defect rate and hers was it.

If you thought a 5-10% defect rate was high, think again. Most computer devices are getting ever tinier that if a speck of dust gets in, the digital device will not function well. Though the manufacturer will try to use class 100 clean room for their production, you never know some dust could be introduced in their manufacturing process by accident. Looking at some of my digital devices that failure rate seemed fairly consistent at about 5-10% defect rate. This rate feels high and if you are one of the few unlucky ones that tend to get the defective item like my brother-in-law who felt he always get faulty digital devices like digital cameras and such, well there you go, Murphy's Law at work!

So now is a matter of claiming the warranty and since my sis-in-law didn't test it till recently (lapse about a few months), we can't send back to Bonuslink to exchange, instead we have to send it directly to the vendor to claim warranty.

The Bonuslink Kingston vendor contact is different from the Kingston Vendor contact that I got from All IT Digital Mall. Anyway we will just follow the directions of Bonuslink vendor instead since it was them who supplied to Bonuslink:

Hit On Sdn Bhd
No 8, Jalan LP 2A/2,
Taman Lestari Perdana,
43300 Seri Kembangan,
Selangor Darul Ehsan
Phone No : +603-8943 4193

The ALL IT Digital Mall Kingston vendor is:

No. 5 Jalan SS21/39
Damansara Uptown
47400 Petaling Jaya
Tel: 03-7665 3939

Hmm.., looks like there are two Kingston suppliers in the Klang Valley.

[update: 20/1/2012]

Recently I bought some higher capacity USB flash drive, and decided to use my older workhorse SanDisk Cruzer Micro 16GB for my Red Fox MP3 player. Initially I reassigned my Kingston DT Mini 10 for watching HD movies on my Sharp LCD TV. But turned out to be a bad idea. The slimmer connection style of USB-A type, lacking an outer case meant the connection can be rather loose on some USB port. Thus it was very difficult for the LCD TV to detect this Kingston DT Mini 10.

My sis-in-law felt that slim type connection was not so good because:
a) Difficult to figure out which way was the correct way to insert into USB port
b) Even if inserted correctly the USB port has difficulty to detect it as the slim USB-A connector without the casing makes it difficult for the connector to connect to each other

I should think so too, never really quite liked this slim styled USB-A connector, though it did make USB flash drive much smaller than the usual standard flash drives.

So I decided to use this as DT Mini 10 as Readyboost device for my Windows 7 instead. If you plan to totally use the 8GB capacity for readyboost, you should reformat it to NTFS or exFAT, since FAT32 has filesize capacity limit of 4GB max. For me, I decided to keep its original FAT32 format and use the balance 4GB space for file storage.

[update: 15/10/2020]

Finally this Kingston DTmini10 gave up on me. I suppose it wasn't hardy enough to withstand the constant readyboost duty. And of course the poor design of the connector points could also be at fault. After testing it on my other PCs, confirmed that the electronics was fried. Still I was able to use it for about 10 years which was not too bad. As the years went by, USB flash memory gets cheaper and cheaper. Now I have a bunch of them and many of my older and smaller capacity flash drives were relegated to readyboost duty for the older PCs and laptop or used as USB boot drive for Linux, Cloudready Chrome OS live CD / installer. Newer PCs and laptops were blazingly fast and didn't require readyboost to help speed up.

Xperia X10 Android 2.1 Update coming soon

My current Sony Ericsson Xperia X10 Mini Pro is running on Android phone version 1.6. Heard about the update/upgrade to Android phone version 2.1 will be released on week 38 or end of Q3. Somewhat earlier than the Q4 released mentioned.

Quick search found the SE blog about the upcoming release for Xperia X10 not just for the X10, but for the entire X10 series, the X10 mini pro and X10 mini.

Ran through the Sony Ericsson website and it seems I can upgrade the X10 Android phone software by ourselves instead of handing it over to the SE service center. If so that would save time but I wonder what are the caveats of doing my own software upgrade?
