Review #61: Samsung Galaxy A50 (May 2019)


Being an early adopter of devices is a huge risk because you don't often know what you are getting into. In some cases, it is less of a risk because the company has a good track record and the device is a flagship one. However, that may not be true of mid-range devices, especially when the company doesn't quite have a track record of providing long-term, timely updates even for flagship devices.

It has been two and a half years since I switched from Android to iOS and the fact that I am still holding on to my first iPhone is a testament to the device continuing to meet my expectations. However, circumstances necessitated the move to a multi-SIM, consumption oriented device and for that, there are no shortage of options in the Android ecosystem that provide bang for the buck. Thus, for all the horrors in the world, I am now cohabiting with two mobile devices that are capable of going thermonuclear.

Review #60: Logitech MX Anywhere 2S ★★★★☆

Prologue:

For a lot of people, a mouse is what you need to simply move the cursor on the screen, everything else being inconsequential. For numerous years, I subscribed to the same school of thought and economised my mice expenses. Such a thought would be sacrilege to a gamer, though thankfully I don't count myself as one. However, that doesn't imply that I ignored the DPI, sensor and button customizations when making a mouse purchase.

While I had given up on office mice a long time ago, I couldn't help but put up the pretence of buying a gaming mouse. As a result, I purchased my first adjustable DPI mouse in the form of the Logitech G90 a few years ago, something a gamer would not be caught dead with. It only had 3 adjustable settings but it went up to 2500 DPI with a polling rate of 500/s which seemed plenty enough for almost everything I did. Unfortunately, the mouse met its demise prematurely in a quirky manner wherein the sensor went dead with the device still being detected and buttons still being functional.

Purchase:

For my next purchase, I needed to go a step further. This could have meant getting a higher DPI wired mouse, but I found better value in going wireless. Due to my setup, my mouse wire often tangled with the keyboard tray and I wouldn't have any more of it. I had a "wireless" mouse in the form of the Logitech M557 Bluetooth mouse which helped me realise the limitations of a low (1000) DPI mouse with a dodgy sensor. The best of both worlds would be getting a high(-ish) DPI wireless mouse and so began my scouting.

Despite my failure rate with Logitech, I wasn't ready to switch camp just yet. Razer has a range of fugly, high DPI wireless mice with a worse failure rate and no local customer support, so it wasn't as if I was spoilt for choice. I had set my mind on not spending more than INR 3500 (USD 50) and this narrowed the field to the point that nothing caught my eye. Raising the bar a bit led me to the concerned product but at 5k INR (USD 70), it seemed a bit much compared to its US pricing of $50.

However, there is an e-tail world beyond Amazon and Flipkart which led me to check Croma and surprisingly, the product was listed for less than INR 3000 (USD 40). Well, to be clear, the listing wasn't for the Anywhere 2S but rather for the Anywhere 2. I called the local store to check the availability of the product and was rather pleased to hear them confirm that the product is indeed the Anywhere 2S. I can only put it down to a product listing error considering the price difference and the fact that it is no longer available on Croma.

Packaging:
As far as packaging goes, it is a case of keeping it simple and elegant, the black-green theme of the box goes well with the box image depicting the blackish-grey mouse with its green power LED. Flipping the magnetically locked box open brings in to the spotlight the thing that you spend your hard cash on.
Apart from the product and documents, the packaging contains a Micro-USB cable which I don't see the use for considering its persisting ubiquity after all these years and a 2.4 GHz Logitech Unifying Receiver (technically transreceiver). The older versions of the "Nano USB" receiver were susceptible to MouseJack, but the one that comes with this mouse (C-U0012) is supposedly safe.

Features:

The reason for selecting the mouse was its versatility. In addition to the Logitech Unifying receiver, it also works with Bluetooth thereby offering universal functionality across devices and operating systems. On Windows 10, using the receiver was as simple as plugging it in, following which the Logitech Options software was automatically downloaded and installed by Windows, offering a pretty seamless experience. Bluetooth pairing is simple too, requiring a press of the button at the bottom to switch to one of the three available slots, each accompanied by a LED. Irrespective of the receiver, it does the job to the effect that wires wouldn't be missed.


The ability to pair and switch between three devices is by far the most utilitarian feature of the mouse as wireless mice tend to be used with multiple devices, in my case with my desktop, laptop and Fire TV. The state of each slot can be deciphered with the LED behaviour, the currently used one doesn't blink, the other occupied ones blink slowly whereas the unoccupied one blinks rapidly. Any occupied slot can be paired again by long pressing the button. The LEDs switch off when the device is in use, thereby preserving battery.

Battery:

Speaking of battery, the battery life is stated as 70 days. I have used it for 45 days now and the battery status is at level 2 out of 3, termed as "Good" within Logitech Options. Low battery life is (supposedly) indicated with a blinking of the green LED on the front face which also doubles up to indicate charging status and completion. I presume it will exceed the stated battery life of 70 days but the only way to know for sure would be to let the battery drain out completely. When it does, charging shouldn't be bother as it doesn't take hours to do a complete charge using the integrated Micro-USB port while a minute of charge provides enough charge to last for 2 hours. Unfortunately, the Micro-USB port cannot be used to convert the mouse in to a wired one which would have been a great addition to the feature set.

Tracking:

While marketing teams tend to generate buzzwords with the sole intention of swaying customers, it seems that they have managed to resist departing the realms of reality with the term 'darkfield laser tracking' as the mouse does uses dark field illumination. This allows for tracking on glass and I can attest to its ability after seeing my optical M557 mouse fail miserably on a glass surface. Even if you are not one to go to extreme surfaces, the 2S does a great job of tracking on mouse pads, a necessity for any mouse warrior.

Software:

This mouse is supported by the Logitech Options software which extends the utility and customization of the mouse. As I mentioned previously, it was auto-installed on Windows and I assume the same for Mac. Unfortunately, those are the only two platforms supported, so it works like any other mouse when paired with other platforms. The ubiquity of Bluetooth implies that the product will have universal support and the only time one is likely to be caught out is when accessing the UEFI on a PC with an unsupported motherboard.

The main benefit of the software is the button customization. While each button can be assigned a distinct function, the button on the face of the mouse acts like a gesture button, combining the button press with the mouse movement direction to provide a total of 5 functions. Unfortunately for me, the customized gestures stopped working after a few reboots and Logitech Options kept on crashing when the gesture button was selected from within the software. This hasn't yet been resolved even after multiple Logitech Options updates, so I assume it is not a priority. In the meantime, I am using the gesture button only for showing/hiding the desktop.

Another irritant for some people would be that the scroll wheel doesn't click. It moves left/right to provide two additional "buttons" but clicking the wheel changes the scroll resistance which some people might end up invoking inadvertently. This doesn't bother me so much as I have assigned the top side button to the middle click function and find it convenient to use for applications and games.


Lastly, one of the key features of the mouse - adjustable DPI is inexplicably made accessible in a manner that beggars belief. While other mice have a button dedicated for this function, in case of the MX series, it can only be accessed by assigning the "Change Pointer Speed" function to one of the buttons which can be a bit misleading. However, for intents and purposes, it seems to refer to DPI adjustment as the function toggles between two sensitivity values on click which can be adjusted on the fly. Moreover, there are 76 steps between the minimum and maximum values which fits in well with the 200 to 4000 DPI range of the mouse in increments of 50 DPI. I prefer to use the mouse at around 1000-1200 DPI for normal use and anywhere between 1600-3000 DPI for gaming and it works admirably for either use cases.

Conclusion:

What's in a mouse? A lot, if you care for it. Even if you don't, the Anywhere 2S is a great wireless option for anybody. If you don't harbour pro-gamer aspirations and have a job to do in front of the PC, then this mouse tackles work and leisure admirably in equal measure.

Musing #70: Early days (of review)

It would be in good humour to pull a fast one on the 1st of April but keeping in line with what's in vogue with tech giants this season, I have refrained from doing the same; though you can always refer to my ode to this occasion from 3 years ago. This might however leave you wondering about the image accompanying this post.

Musing #69: Modern Monetary Theory


Heterodoxy can usher in amusement and stimulation in equal measure. In the context of economics, I have seen it pop up quite often at the mention of Modern Monetary Theory, to the extent that I have run out of fingers to count on. In the same breath, MMT (not this one) is equated with the license to print as much money as needed with it being a "creature of law". This makes nought sense to anyone having the faintest idea of economics and neither does the zero sum game between government spending and private saving.

Even if the theory has merits, it is often over-simplified by those pushing for its acceptance in the mainstream, which in turn makes it sound quite crazy. After quite some time, I have come across a source that does a simple and good job of discussing it. In general, I would recommend subscribing to the 'After Hours' podcast considering the fact that I ended up binge listening to it the first time I "tuned in".

Considering what happened in Zimbabwe, it will take a lot of effort to convince anyone that "unlimited printing of money by government" is a good idea, all things considered. At the same time, running fiscal deficits is a great idea, assuming there is a limit to it and that you are getting your money's worth. After all, debt makes the world go round. Running a deficit with a manageable debt-to-GDP ratio makes a lot of sense provided the government is getting a positive ROI in terms of social and economic benefits. What makes less sense is turning fiscal and monetary policies on their head without understanding their due impact.

There is no denying that the economic system is a belief and a social construct but there is no turning back the clock as well. Instead, the idea is to bring in meaningful change and MMT can contribute to that in parts, though not as a complete alternative. In the meantime, Calvinball anyone?

Musing #68: Making the most of Audible trial


Listening to a book doesn't quite have the same panache as reading one, but sometimes it is the only option. While I am an avid fan of podcasts on long commutes, sometimes audio books can fill the void quite well. However, in case of audio books, for me, it is unabridged or nothing, which depending on the author's preference for brevity can extend to numerous hours; a significant investment of time whichever way you look at it.

Review #56: Xgimi Z6 Polar ★★★★½

Update #1 (March 1, 2019):

In my video review, I had stated the audio to be just about good enough, despite the Harman Kardon branding. In fact, I would still recommend getting an external speaker for the best experience. However, if that is not possible, then the wizardry mentioned subsequently will enable you to get the most out of the Z6 speakers.


As it turns out, Xgimi has a hidden "Design Menu" within GMUI which can be accessed, at least in the case of Z6, by long-pressing the "right" direction key on the 'System Information' screen. The "hidden" menu pops up on the left as seen in the above image. At this point, I should make it clear that the 'Audio' settings that I am discussing is listed under 'Non-standard options', so there is no guarantee that it wouldn't damage the device. Hence, caution is advised.

Within the 'Audio' menu, there is a "prescale" option that goes from '0x00' to '0xff' in Hex, or "00" to "255" if you prefer Base 10. My rather rusty knowledge of electronics from eons ago helps me recollect the use of a prescaler in a microcontroller to determine which oscillator pulse triggers an interrupt. How the prescale value specifically impacts the audio in this case is beyond me.

But impact the audio it does. The default value is set at '0x01' and on changing it downwards, I could immediately perceive an increase in volume while incrementing it didn't seem to have much of an impact. Thus, it was time to note down some observations. I changed the value to 2 levels from default in either direction and then to various quarter levels (25%, 50%, 75%) to gauge the impact.

If I don't go by the values alone, then I would say '0xff' seems the loudest, probably because it is also extremely harsh to listen to. Practically, '0x00' and '0x7f' are the best values for this option. They are nearly identical in volume, but I found the sound from '0x7f' to be livelier, probably because it adds the right amount of "harshness" that becomes unbearable at the higher values.

It is miles away from the quality I get from the JBL Xtreme, but in terms of loudness, it makes the Z6 much more suitable for a small room.


Original Article (December 18, 2018):

My previous post on the Z6 alluded to the upcoming review but it was around that time I decided to embrace the video format over written words, not that you are spared reading, as the video is littered with text overlays.

It also provided me an opportunity to try out various non-linear editing systems (NLE) and I eventually settled on Lightworks. Considering it took me a few hours to come up with this output, I can't recommend it enough, simply for its lack of a learning curve, though I expect mastery of it to take ages. The video itself is a farrago of poorly shot video, PowerPoint slides and images, so make of it what you may.

The down side to using the free version is that export is limited to 720p but I am sure you can live with that. With that (again), I will let the video to do the talking, especially as I haven't done any.
