The Ultimate Budget Phone : Redmi by Xiaomi

I can't believe I'm writing this but I'm impressed enough by this phone that I thought I'll pen down my first impression. First thing first, Xiaomi is the company and Redmi is the model of the phone. This is the first phone to be sold officially by Xiaomi in Singapore. If you follow the mobile space, I'm sure you would have heard of the China-based company called Xiaomi (literally means small rice, and Redmi literally means red rice).

So on 21st Feb 2014, Xiaomi launched the very first online sale for this phone in Singapore at 12 noon. According to news, the phone was sold out within 8 minutes. I'm not so sure about that since I actually placed my order on the 22nd Feb, exactly 1 day later. And the phone arrives at my doorstep today. I must applaud the UPS guy who made this possible.


It came in a nice little brown box. On the left is the box containing the phone itself, and the stuff on the right is the 'bundle' which I bought together at the same time. The bundle consists an extra battery, a desktop charger, screen protectors and a silicone case. Xiaomi also bundled 2 pieces of SIM adapters in the whole package. All these for the unbelievable price of $197 Singapore Dollars. That is approximately USD $156. 


Here you are with all the stuff taken out from the box. The biggest box in the center is the phone itself and it comes with just the battery and a standard micro-USB cable.



Notice the little silver foil covering the camera lens? I think that's a nice little touch. Despite the name of the phone, the color is grey, not red. However, you can buy additional back covers easily, including the red color one. Next, I need to insert the battery and SIM card. The instructions says I have to pry from the lower left corner of the phone (yes, I read the quick start guide!). There's a little groove on the back case where you can pull the cover off. It came off pretty easily and it does feel a little flimsy. You know, the kind of feeling that everything will fall apart.

A good buddy help me cut my data SIM from the standard form factor down to the nano SIM form factor. And now I have to use the adapter to put it back into this phone. What irony. Due to the way the orientation and the position of the SIM slot, you do require a little effort to get the SIM+adapter securely fitted into it. And then the moment of truth. You press the power button on the right side and waited for the phone to power up for the first time.

It took quite a while and that actually scares me a little. But the result is the setup screen greeting you

It's very straight forward. Pick your language, choose your Wifi (oh it doesn't do 5Ghz 802.11n by the way) and you're almost done. As part of the setup, you have the option of synchronizing the phone to Mi Cloud, as well as the standard Google account. Yes, Google services are available on this one! I setup both. Lastly, I notice my Starhub data SIM is not working. So I have to figure out where the APN settings are and change the APN name to match. And when all's said and done, here's the final home screen.


Not bad for a $169 phone. The bundle cost $28. Total damage $197. I played with it for a while. The build quality is exceptional for a budget phone. It feels... hefty and solid in the hand. The screen looks good and the UI is responsive for what is considered a budget processor from MediaTek. It runs MIUI v5, which is based on Android 4.2. At least I don't have to worry about the WebView bug.

Enough of fiddling. I have to apply the screen protector. It stated on the packaging that there are 2 pieces. Pleasant surprise there, I was only expecting one. When I open up the package, even more surprises.


There are 3 in fact. However, the 3rd piece is termed as 'practice'. You can see it in the picture. For those who don't understand Chinese, I'm sorry. The one on the left is the 'practice' piece while the one on the right is the 'real' piece. I've been buying screen protectors from China all my life and this is the first time I've seen this. Nothing much to say about the protectors, they... just work. I got the clear type, which I don't really like but when I ordered, they ran out of the anti-glare type. I guess something has to give...

I said that prying open the back cover feels a little flimsy. You have to do this if you're going to swap batteries unfortunately. From that single experience, I'm not sure if I really want to swap the batteries now, or just use those portable chargers which are literally everywhere.

Lastly, there's the silicone case. I picked the black color and it looks like this


It fits snugly and barely covers the sides when fitted. So that's it. I have yet to try out the camera and the various multimedia functions. So far, it has performed well surfing the net over Starhub 3G and wifi.

It's amazing Xiaomi can packed so much into this $169 phone. I think this is going to dominate the budget smartphone segment for at least the next couple of months. For those comparing this with the Samsung S5, don't be silly. And those comparing this to the Moto G, you may have a tough choice there.

On the Mac : Mavericks and Safari TLS/SSL exploits

OK, I noticed about a third to one half of my audience reads this blog on iOS devices and Macs. I guess it makes sense since no Windows users will be interested in these 'On the Mac' series of articles. If you have not notice already, Apple quietly releases iOS 7.0.6 and 6.1.6 over the weekend to address a vulnerability in the underlying SSL implementation framework.

My advice to all of you : Just Patch It. If you have iOS 7, upgrade now to 7.0.6 and likewise if you iOS 6, upgrade to 6.1.6. The vulnerability is serious enough for Apple to warrant a standalone iOS release, even for iOS 6. Apparently, iOS 5 is not affected. More information at HT6147.

It has also been discovered that the same vulnerability exists on Mavericks. There is no patch at this point from Apple so you have to stay tuned for updates as to when this patch will be made available. Meanwhile, you can try to mitigate the risk by not hooking up to public Wifi systems (where the exploits are most easily executed). Perhaps you can just use FireFox or Chrome for now until Safari is fixed.

Update : Apple has rolled out Mavericks 10.9.2 which contains the fix for the TLS/SSL vulnerability.

On the FileServer : The Hardware - Hotswap cages, enclosures and controllers

In this series of articles, I'm going to briefly jot down my setup. Hopefully this can provide some insights and ideas to those who are considering building their own NAS. Now, you might ask why a NAS at home? And even if we want a NAS, we can just buy one off the shelf, so why build? These are valid questions and I will share with you my thoughts. I'll then go ahead and list down the main components of the hardware I use.

So, why do you even want a NAS at home? Let's face it, in this digital age, you would have build up a lot of photos of your kids, families and loved ones. Probably videos too. You're likely to have a massive iTunes collection, and maybe a sizable movies collections as well.

Traditionally, you have a desktop (or laptop) and you dump everything on it. The more careful ones will buy an external drive (see some of my recommendations here). At some point in time, you realized you run out of disk space, or you simply need more. Or perhaps you want to share them with another desktop (or laptop) in the household? That's where a NAS will come in useful. It provides a central location where you can deposit your digital life.

Why build your own then? Yes, you can just buy any one of them off the shelf. But I prefer the flexibility of building my own and to also satisfy the geek in me. It isn't really that difficult, you just need a bit of planning and some basic system administration skills. In this article, I'll continue with the hardware I use and then in subsequent articles, I'll follow through with the software and the final setup.

In a typical NAS, one of the key features is that you want many drive bays, which can be easily accessible. Why is this? The more the drive bays you have, the more disks you can plug in, plain and simple. But why do you need it to be accessible? Drives fail. It's not a matter of 'IF' but 'WHEN'. When a drive fail, you don't really want to open up the case and pull the drive. You want to just yank the dead (or dying) drive out from its bay simply by pressing a button or lifting a lever. Because of this requirement, I install what is known as a hot swap cage. There are 2 types, 3.5" or 2.5". 3.5" are more common since they provide more value compared to their physically smaller 2.5" brother.

You can find these hot swap cages on Amazon, an example (3.5") will be ICY DOCK FlexCage MB974SP-2B Tray-less 4 x 3.5 Inch HDD in 3 x 5.25 Inch Bay SATA Cage - Front USB 3.0 Hub. This specific model provides 4 bays, and uses up 3 5.25" bays in your tower. This is also known as a 4-in-3 cage. There are also 5-in-4 cages available. You need to plan a little bit further and decide if you want the 4-in-3 or 5-in-4. I personally use a 4-in-3.

An example of a 2.5" hot swap cage is Thermaltake MAX-1542 Backplane HDD Cage Hot Swap Removable Hard Drive Kits 2.5-Inches SAS/SATA RAID Ready RC1400101A. In most cases, you don't want these unless you plan to use the smaller 2.5" form factor drives. For me, I do have some 2.5" drives lying around (as a result of multiple upgradings of laptop drives) so I got one of these. I use the 4-in-1 type which takes in 12mm 2.5" drives. I have personally saw 6-in-1 cages (Thermaltake MAX-1562 Backplane HDD Cage Hot Swap Removable Hard Drive Kits 2.5-Inches SAS/SATA RAID Ready RC1600101A) but they can only take 9.5mm drives.

Alright, so I have a 4-in-3 and a 4-in-1 cage installed. It can take in 8 drives. Typically, an Intel-based motherboard (like ASUS P8H77-M/CSM LGA 1155 Intel H77 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard) comes with 6 SATA ports. You need an additional disk controller to provide the extra SATA ports. I purchased an Dell PERC card off eBay. It's really a rebadged LSI Megaraid SAS controller card. This is a somewhat high-end card meant for servers so you might want to go for 'consumer' class controllers, like StarTech.com 2 Port PCI Express SATA 6 Gbps eSATA Controller Card - Dual Port PCIe SATA III Card - 2 Internal/2 External Card PEXESAT322I.

If you need more than 8, or perhaps you just don't have enough bays internally in your tower, you can opt for external enclosures. There are multi-bay external enclosures that run over USB3 or eSATA. I hunted for a while before settling for this bundle - TowerRAID TR4M+B - 4 Bay eSATA RAID 0/1/10/5/JBOD Performance Tower w/ 6G PCIe Card (Black).

One thing to note on the difference between an USB3 enclosure and an eSATA one. You cannot hot swap individual disks in an USB3 enclosure. This means if your enclosure has 4 disks, and one of them is dead, you have to bring all 4 disks offline before you can pull the dead disk. eSATA does not have this issue. However, in order to use all 4 bays in an eSATA enclosure, the eSATA controller card must have the 'Port Multiplier' feature. If you buy the bundle listed above, it will work nicely.

If you choose to still go with USB3 (it's definitely a lot easier to setup), you should seriously consider Mediasonic HF2-SU3S2 ProBox 4 Bay Hard Drive Enclosure with USB 3.0 & eSATA. For Singapore readers, just go SLS and buy it. It's known as Hotway Probox here.

Alright, that's all for now regarding hardware. Do also note that I don't build for performance (despite having a server class SAS controller) so you need to understand what you're buying if you choose to follow my hardware setup.

Do feel free to ask questions if you have any. I'll try to answer them, and stay tuned for the next installment where I'll talk briefly about the different drive types and what you need to look out for. And if you find my articles helpful, you can help to support the site by buying through the links above. Thank you!
