Re:DevHub.app – Developer Utilities for macOS on Monday September 09, 2024 @01:51AM (#41485793)
Nice.

I built https://utils.foo last week. Client side only + ads free. Idea is to keep adding more utils to it, but keep it client side only.

Show HN: Client-side ads-free dev utils (diffs, time conversion, JSON formatter)

https://utils.foo/

utils.foo a fully client side, ads-free developer utils app. Today, it has a timestamp converter, base64/url encoder/decoder, json & diff utils, quick pivoting data.A lot of these exist, but often buried with ads or unclear data usage. I wanted to build something for myself that is ads-free and easy to use.My goal is get to top 20 commonly used tools, make them feature-rich and then reduce...

At Stripe, this was also framed as BLUF - bottom line up front.
Please do, that would be awesome.
How does this compare to hurl.dev?
Re:Hurl, run and test HTTP requests with plain text on Saturday November 26, 2022 @02:58AM (#33750798)
Yep

If you're going to do a single request or a few requests in isolation, curl is the way to do.

If you wanna do a full fledged testing suite, might as well using a proper scripting language or a test framework.

Hurl hits the spot between those two for me.

Re:Hurl, run and test HTTP requests with plain text on Friday November 25, 2022 @11:00PM (#33749773)
The abstraction is provide better UX. Anyone will have to write stuff over telnet to provide chained requests, variables, assertions, etc. Once you do that, you basically get a reimplementation of hurl.

Because liking a cli is an individual preference and lots of dev, including me, would prefer it and find it useful.
Re:Using load shedding to avoid overload on Sunday October 10, 2021 @02:18PM (#28820699)
I saw this comment and thought this exactly described what my $previous_company did. Then, I saw the username :-)
Yes, because most services haven't met the full scope of the RBI circular yet - sending pre-debit notification, self serve mandate revocation, etc
That isn't how it will work

- First charge needs a AFA and it will setup a mandate - Subsequent charges will use that mandate and work without 2FA - Cardholders need to be notified in advance of a debit and be given an option to cancel

What's breaking now for most services is handling the third part

2-random was also used in this HDFS change - https://issues.apache.org/jira/browse/HDFS-8131.

Default block placement policy chose datanodes randomly for new blocks. This change selects 2 datanodes randomly and picks the one with lower used disk space.

Re:Ask HN: How to get better at large system design? on Wednesday January 16, 2019 @01:46AM (#18918763)
Thanks.

This has been my approach thus far. The place where I work allows for practical applications of this (scaling systems to millions of requests per second, having no downtime operations, doing BCP/DR, etc.)

2 things on this - Learning by doing sometimes feels like spending time on discovering things that would have been obvious given the right resources to look at - It's still easier for non-functional aspects of system where there can be quicker feedback. The more abstract part to me is functional design of large systems

For e.g., there are great resources for more "basic" patterns (on Java design patterns, Effective Java, Clean Code, etc.). Are there such resources for roles beyond SSE?

I wrote a lot of code for payments processing at an Indian e-commerce shop & see/make it scale from 100s of QPS to ~200k QPS. Just having the code paths exercised by so many people over a day gives me joy.

One change that I will not forget that made the highest "perceived" impact with a one line change. The payments flow was at a different domain the rest of the site. This meant the users incurred a fresh set of DNS lookup, TCP connection establishment & a SSL handshake cost. The change was to load a "pixel" image from the payments domain a page before. It dropped the first call latency from 550ms to 100ms :-)

Ask HN: How to get better at large system design?

There are a lot of resources for learning algorithms, code design patterns, etc.As you grow, what are the good resources for system design patterns? How did you get better at it? For large system designs, like say a fulfilment ecosystem, the choices become more abstract with not immediately clear trade-offs.

FYI - I'm not the author of the article. I found it very useful and hence posted it here on HN.
Re:The latest on Messages, Allo, Duo and Hangouts on Wednesday December 05, 2018 @11:04PM (#18615308)
Hangouts Chat is such a botched launch. It is backwards compatible with single user chat and not group chats. It effectively ensures that people cannot completely migrate to it. The overhead of keeping 2 apps and getting the same notification twice was too much - ended up going back to classic Hangouts.

Re:A Closer Look at the $13B Premium Eyewear Market on Monday October 09, 2017 @12:59AM (#15431670)
You’ll get premium eyewear in India for $150. Though, it will take around 3-5 days to get it after your order. Good quality ones that last would be $60-80.

Thanks! That's the one.

Ask HN: Help remembering a site posted on HN?

Few months back, there was a post about this particular site/app. We could store notes about people we met, for future interactions; store birthdays & reminders, etc.Does anyone remember what it was? Tried search with few keywords, but to no avail.

Tried it on www.flipkart.com (Amazon of India) and it scores 72-75/100. AliExpress scored 78.
