    NUS SoC Summer School is finally over. Well, I used up this month’s study leave and took 1 day of annual leave to go for 2 days of summer school and it is finally over.

    I was thinking of writing a review on both classes that I went for but is feeling lazy to do so. Maybe I will just summarise my thoughts about both classes here.

    If you have read about it here, you would have known that I have signed up for “Cryptocurrencies: Security Challenges & Solutions” and “An Introduction to Sound Music and Wearable Computing” classes.

    The cryptocurrency class is really good. I have learnt more about the technical background of Bitcoin and Ethereum like proof of work and the up and coming proof of stake for Ethereum. It helps since I am recently exposed to the world of cryptocurrencies (thanks to Alan for introducing it to me). The session makes me realised the various types of risks involved in cryptocurrencies investment such as the risk of attacks on the languages (eg. Solidity) used in writing Ethereum blockchains. I wouldn’t have known about such risks if I didn’t go for the session. After the session, it makes me think twice about investing in cryptocurrency, especially so when the attack vector seems to have increased for smart contracts like Ethereum, as compared to Bitcoin with the introduction of a code attached to the blockchain.

    We also learnt about the key properties of a blockchain (which is the main technology behind cryptocurrencies).

    Key properties of a Blockchain

    • Immutability
      • Cannot change existing blocks
    • Validity
      • Only the owner of the coins can authorize the transfer of the coins
      • Eg. Alice cannot transfer Bob’s coins
    • Consensus
      • Nodes “agree” on the blockchain state
      • Select one, valid block as a group per round
    • Failure Resistance
      • Replicated checks on each block
      • Different protocols can tolerate different levels: 5%, 25%, 33%, 51% and 99% failure rates

    As for the music computing class, it is like a waste of time. The stuff taught in the first part of the class is rudimentary (things that you can learn in the first 2 years in engineering school). As for second part of the class, it is time spent to remix some music and seeing the recording studio. The last part of the class were for the PhD students and postdoc fellows to introduce the research area that they are working on.

    The good part for the class? I met 2 new friends who just joined the MComp in CS programme. Other than that, I don’t think I learnt anything new from the class.

    I went to order a pair of Gentle Monster sunglasses from Gentle Monster online shop in  the end. Well, yolo (you only live once) attitude? But bleh, I do need to save money. I am also thinking of getting Microsoft Surface Pro 4 since my Windows laptop refused to boot up and work properly the last time I used it. Hopefully it will recovered soon. I had backup my files so it is not too much damage done if it suddenly died. But I still prefer a Windows OS since my main storage is already on the hard disk formatted for Windows OS (I forgot the actual name of the storage though). Guess that is going to be the advantage Surface Pro 4 has over Macbook Air or Macbook.

    Luckily for me, I can still take advantage of student discount so it isn’t too bad.

    I have finally opened my technology blog at Altosome. Do take a look at it here. I decided not to go for customised themes and just stick to the Twenty Seventeen theme instead and use the photos I took as the header images.

    I haven’t really started any technology articles and is looking for inspiration for it. Is there anything you guys would like to read about?

    Oh yes, those technology articles will also be found in ViolinStar.NET as I would like to continue to use ViolinStar.NET as my main blog, while leaving Altosome as a purely technology related blog. :smile:

    Jetpack is still not working well for me. I still can’t blog from my mobile apps which probably explained why I am blogging lesser these days. The issue has been there since April and I have raised tickets with Jetpack support team since May. It’s already July and it is still not resolved. Guess Jetpack support staff don’t really care much on their free customers. Also thank goodness I didn’t pay for my Jetpack subscription either. Otherwise, I would have felt that I wasted my subscription fees.

    Thus, I am sticking to the good old web interface to blog on mobile which, I must say, is quite troublesome. But oh well. What can you do if Jetpack support staff and WordPress support staff are not helping things?

    I keep getting the error that “The Jetpack site is inaccessible or returned an error: transport error – HTTP status code was not 200 (403) [-32300]”. I even gone to the extent of working with my host, Ariel, to resolve it but it seems like whatever the Jetpack support staff had suggested so far (in the last 3 months), is not helping at all. Now it seems like they are not even interested to help and I am still raising support tickets and following some of their (repeated) steps to try to resolve the issue. The trend is always the same, once you tried those steps and it is not working –> they don’t know what to do so they don’t reply you –> then out of the blue they closed your ticket as Resolved. Sigh.

    Now I am posting on their support forums and hopefully I can get some helpful replies.

    I was surfing Youtube earlier and found this video which I find it quite inspiring. It’s about the perks of being single life.

    Some pros of being single pointed out in the video:

    1. Save money! Whoa, totally. But I think I am quite a spender though. Hahaha.
    2. No need to consider about the significant other. More YOLO-ness, maybe? :smile: 
    3. More time for yourself to learn new stuff?
    4. Friendships get infinitely better – know who are the friends that can last longer.

    I particularly liked this quote from Wes in the video too.

    “Investing in yourself when you are single is going to pay when you get into a relationship” – Wes

    Anyway, the video is embedded below so watch it if you are free? :grin: 

    Oh, it’s great to have a 15inch laptop (such as MacBook Pro) cause I get to put the Chrome on my left side of the screen to blog while watching Youtube. Hehe. Glad that I listened to Nicholas’ recommendation to get a 15inch MBP instead of the 13inch MBP. It’s really good for school stuff too.
