You missed Gupta.. but I too consider Islamic/Mighal as well as British time too Golden period from world progress perspective.
Ballu··on Deaf girl is cured in world first gene therapy trial
Could you provide the ref/details of this particular gene therapy and FDA views? I can understand why the FDA wants to move ahead slowly unless the condition is life-threatening or the impact is life-changing.

great read, thanks for sharing
Ballu··on Fake recruiter lured aerospace employee with trojanized coding challenge
LinkedIn was a great platform, weaponized by Microsoft as the biggest security risk. There is no innovation for security, making it feature rich and more user friendly.

Could you share the book details?
Ballu··on After 20 Years as a Prosecutor in Illinois, I Quit
And he moved to Madison, WI. Doesnt that city also have crime issues (atleast in media) like Chicago? https://www.linkedin.com/in/jason-poje-54b4a818a/
Ballu··on Google Pixel Fold
I cant think of using phone without non-slippery case. and there are lot like me :)
Ballu··on Your First LTE
Its not unlicensed, you have to apply & get the usage rights from FCC. If some one using at that location, you cant use. Plus, FCC has right to revoke temp or permanently the usage right. If I am not wrong, you have to pay minimal fee. To implement this architecture, you have to connect your private 4G/5G network with SAS service providers. https://cbrs.wirelessinnovation.org/sas-administrators https://www.celona.io/cbrs/cbrs-sas

Ballu··on Meta is cutting prices for its VR headsets
I created new account, just for VR. Not adding any friend. I know, Meta algorithms will be able to find identity easily with WiFi/Location info.
Ballu··on Meta is cutting prices for its VR headsets
Used to go on Facebook marketplace for $150, I sold for $175 (boxed) which I got free. (Yes, Got 2 free. Kept one and even kids rarely use).
Ballu··on The E-Ink Badge
Could you recommend any good similar size as well as functionality LCD for my personal project? Charging is not an issue (short term use), minimal equipment and clarity at screen are key requirements.
Ballu··on Train derailments occur roughly 1k times a year in the United States
Thanks.. fascinating read. We have all the data and we know the issues, any reason these things are not tackled?
Ballu··on Apple TV prompt requires another Apple device
I have the same issue with any Apple services, Apple wants me to use iOS device (I faced this issue when tried to upgrade the Apple Music to bundle with other services).
Ballu··on Health insurers just published close to a trillion hospital prices
Could you post some good links you read/browsed? Google is providing too much junk and difficult to reach any high level conclusion.
Ballu··on The Trouble with 5G
Beamforming, MIMO, etc are not like you need for FR2, but without that you cant deploy. At this high frequency, the range is in 10s of m with antenna size of coin. To get the gain, you need MIMO and to get the distance, you need beam forming. Both MIMO and beam forming has more advantages, but without these technologies, almost impossible to deploy more than 50GHz. We will mmWave, but will take time. Thats how mobile world works. The high end of the targeted band is usually used at the end of particular generation of mobile or the next one. BTW, mmWave is having issue in adopting in mobile world not the FWA. My understanding is, both Lumen and Verizon are going ahead with mmWave band for FWA.

Regarding THz, FCC already opened the band till 3THz for 6G testing. I dont track, but next WRC might be planned for 2024 or 2025 (because of COVID, all the schedules are screwed up). The next WRC will kick start the standardization fo 6G and there is more possibility of THz to be part of 6G. Although as I mentioned earlier, my guess is, it more than a decade before THz band will be in use for mobility.

Ballu··on The Trouble with 5G
Then you are not getting 5G. In FR1 (sub 6GHz), we are not going to get much advantage. In the end, there is a limit of data you can send per Hz. This is not increasing from 4G to 5G (yes, you can use higher coding mechanism, but that's only for short distance, otherwise noise impact negates all advantages). To get the higher bandwidth as predicted and expected, industry has to move to FR2 (24GHz+/mmWave, I don't want to go into the discussions that mmWave starts at later band, the difference is statistical error). To support mmWave, standards bodies defined new standards/adopted technologies like beam forming, higher matrix antennas etc. And thats really a difference in 5G from 4G standards releases (along with cloud native core network with more simplistic IP routing and use of polar codes for control plane). In 6G, we are going to see Tera Hz band allocated for mobile network. Saying mmWave is not 5G is not accurate. You would not have needed 1000s of pages of standards for FR1, with little enhancement, LTE would have supported.
Ballu··on Cinema’s greatest scene: ‘Casablanca’ and ‘La Marseillaise’ (2015)
Top comment on youtube (makes sense, how lively this scene came out):

"Interesting thing to note: in the Casablanca script for this scene, NONE of those actors were given the cue to cry. Due to the fact that this was being filmed whilst France was occupied by Germany in the war, and coupled with the fact that a lot of these extras were French or from French territories, a lot of them swelled up with emotion during the song and started crying spontaneously. Those tears that you see on their faces, my friends, are truly genuine! That's why this has always been my favourite scene!"

Ballu··on Purple dye extracted from sea snails made the Phoenicians rich traders (2020)
The prohibitive cost was one of the reason purple is used only in 2 countries flags, Its even once banned by British royalty except royals to reduce expenditure by commoners.

Ballu··on Homebuilt pickups: How underage teens skirt the law to drive in Sweden (2016)
I think its a speed limiter which is critical. No onw will try to put mentioned vehicles in 15yrs old hand. :)
Ballu··on Kodi: An Open Source Home Theater System
I used to play with these software long time back, Kodi was the last one before moving to "whatever" stick :) (And I am not into media now) But I have question regarding media, what are you going to play? Where are you going to download the movies/songs, etc unless use illegal ways. It was amazing journey of few years for me, ripping CDs, DVDs, VCDs, BluRay, HD-DVD, etc and playing all those on TV with Kodi box. (Eventually moved to WDTV box).
Ballu··on Knowledge Representation in Sanskrit and Artificial Intelligence
wait.. put ref when you are saying " political context to it which cannot be set aside completely.". What political context, are you talking about. I am not linguist or AI expert. But most of your so facts are of no where related to paper as well as authenticity of the work. Check the author as well as date of the paper.
Ballu··on India tells public to shun Starlink until it gets licence
By default, all satellite operators are blocked in India. I haven't checked in last year or 2, you cant even use Garmin emergency devices which are becoming common in west outdoors. To use the satellite phones, you need to apply to the federal gov (called Central gov in India) and you can rent the phone from ministry. Atleast, thats the process for tourist or who are entering India from other countries. There are some changes happened in last 1-2 years, few satellite companies got the lic to provide services, but I am sure all the devices and services are highly regulated.
Ballu··on AWS Private 5G
That's the different domain. 5G standards are defined for Licensed, unlicensed as well as non-mobile world (means the core network can support all the different access technologies). CBRS is licensed band, just free to use but you have register. 6GHz is new band opened for unlicensed spectrum. It will mostly be used by next generation WiFi (may be WiFi 6 too). Any other technology can use that band too and 5G standards may enhance to support this band or may define other technology too. Just last month, ITU accepted the DECT (remember cordless phones) technology to be part of 5G ecosystem (5G core will be able to support devices with DECT air interface). But CBRS band is different and its more about similar to current mobile ecosystem but in private domain.

CBRS cant be used for WiFi or other technology (only 4G in US at this point, most probably 5G in future.. 3GPP defined OFDMA based air interface). 6GHz is unlicensed and mostly will be used by WiFi.
