I started using Google Notebook around 2008. Once I received a notice that it will shut down, I switched to Evernote around 2012. Unlike Google, note-taking is the central business of Evernote, I thought I would be fine. I was wrong. Evernote became terrible over time. Then I heard about a service called Notion. I deliberated and decided to wait out. Turns out a new cool kid on the block showed up soon enough. It was called Roam Research. They had such an enthusiastic fan following that they decided not to even have a freemium model. I was tired of moving notes from one proprietary system to another. And decided not to use either Notion or Roam research.
Finally, in 2020, I came across Obsidian and decided to make the move. Obsidian is a simple Markdown-based note-taking application. The best thing is that it does not store your notes. You can store your notes on your favorite cloud provider. And if Obsidian ever shuts down, your notes are not only readable in a plain-text editor, but also can be modified/viewed by a gazillion other Markdown editors. Obsidian isn’t as fancy as Notion with dynamic views or anything like that. But it gets the job done. And I can be certain that my notes will be accessible for decades to come.
There are tons of hyped-up claims surrounding React Native that are worth addressing.
The reasons why companies run for React Native are usually,
- We can use one codebase for Android, iOS, and web apps. Or at least, Android and iOS apps.
- Facebook uses it
60 milliseconds is when we notice something isn’t immediate. Any user interaction, that involves sending data over the network or doing heavy computation on it, usually takes way longer than 60 milliseconds. So, we end with a progress bar. There are two broad categories of progress bars, one that shows the absolute/relative progress, a determinate progress bar, and one that does not an indeterminate progress bar.
We all have to make significant code changes from time to time. Most of these code changes are large. Consider the scenario that you merged one such significant change, and then other team members made a few more changes on top. Then a major bug is detected. You desperately make the fix. It makes it in. You declare a victory, and a few hours later, your colleague notices another bug/crash/performance regression. Your commit cannot be reverted. It isn’t just about you. Many others have built on top of the change you made—the code sloths along in this broken state for a few days before you eventually fix it. Everyone has faced this issue at some point or the other.
Money serves three purpose – unit of accounting, a medium of exchange, and a store of value. Cryptocurrencies have been compared to Programmable Money. Anything programmable requires an experimentation platform for iterations and improvement. Bitcoin seems to have won the “store of value” battle. Ethereum has the developer mindshare and is the preferred experimentation platform. Multiple cryptocurrencies are still fighting the battle to be the medium of exchange.
The amusing part is that every cryptocurrency startup envies Ethereum’s developer ecosystem and is trying to attract developers. But there isn’t any real value capture being the experimentation platform. A successful product has a high chance of leaving Ethereum and migrating users to its chain. The real battle, I believe, remains in becoming the medium of exchange, being the programmable Visa & Mastercard equivalent.
Earlier, the Software world was rigidly divided between closed and open-source software. Microsoft Windows is closed-source, GNU/Linux is open-source. Microsoft Office and Lotus Notes are closed-source, LibreOffice is open-source. Turbo C++ is closed-source, and GCC is open-source.
But now, a new class of software products has emerged whose core is open-source, but still, the open-source software is of limited use. One model is to offer some critical and useful functionality in a closed-source layer via a managed service in AWS/GCP/Azure, for example, Redis is open-source, but useful modules on top of it are not. Another model is to use licensing gimmickry, for example, MongoDB is licensed under SSPL which requires that if anyone offers MongoDB as a service, then the source code of the full service must be published under this license. The third approach is to make the core software open-source but make it dependent on closed-source cloud services. For example, the node package manager (npm) is open-source, but a closed source company owns the default npm registry. Android is open-source, but most day-to-day application ranging from Google Maps to Google Music are closed-source. Now onwards, rather than calling such software open-source, we should call them closeum.
Consider this email,
And now consider this one,
You signed up for the Orchard beta not too long ago, and we’re excited to finally send you an invite!
(Just to jog your memory, Orchard helps you make the most of your relationships, keeping you up to date on where you’re spending your time and who you need to catch up with. It’s somewhere between a personal CRM and a todo list for your connections.) [Emphasis mine]
You should receive an invite from Apple’s Testflight service in the next few minutes. It will contain a code or link you need to install the app. You’ll also need to have the TestFlight app installed on your phone. If you need us to send the invite to a different email address, just reply to this message and let us know.
Once you’ve checked out the app, please send us your feedback — this is a beta and we need your help to improve! Be honest, frank, and opinionated: you won’t hurt our feelings. Bugs, ideas, concerns, etc all fair game. You can reply to me or send to firstname.lastname@example.org.
Brian and the entire Orchard team
Which one do you think your early adopters have a higher likelihood of understanding and responding to?
Don’t forget while you might live and breathe your startup, your early adopters have probably signed up to try several such services, and unless you remind them what your product is about, they might as well delete the email and move on.
All cryptocurrencies are eventually tied to a “private” key. You lose this key, and the funds are gone, forever. Millions worth of bitcoins have disappeared from the circulation due to lost keys. You can memorize the key by mapping it into passphrase consisting of memorizable words but if you forget that, like many others, the coins are unrecoverable. An alternative is to trust a centralized service like Coinbase, but then all the benefits of investing in a decentralized currency are gone. Lastly, one can use a hardware wallet, but again, if you lose the wallet, the key is lost. If you keep the key on your device, then a malware might target and try to steal it someday. Thus, even if you are bullish on cryptocurrencies, there are no good decentralized ways of holding a significant chunk of your net worth in cryptocurrencies.
The problems are compounded further by the fact that to a great extent, the key access is all or none. If you lose your key, you lose all the funds. If I got hold of your key, I could transfer 100 % of your funds, irrevocably. Compare this to your ATM debit card, if I get hold of it, along with your pin, there is only so much damage I can do before the ATM limit hits. Further, your credit card used on a malicious website can hit you with a limited amount of fraud before the fraud warnings block the card to prevent further loss of funds.
An ideal approach, hopefully, will consist of decentralized smart contracts comprised of multiple keys tied to the same passphrase with a different set of transfer limits. So that, if one forgets one word in the passphrase and cannot access 100% of the funds now but can access at most 1% funds every day and slowly drain out their account to a newer account. Some of these unlocking codes will be held at different places, some centralized services for custody and ease of use; some kept on the personal device for ease of use where even if they get stolen the damage is contained. A further addition could be a beneficiary account where the funds would be transferred to in case the account lays dormant for a certain period.
