The curl user poll 2016
Drive
curl and libcurl 2016In order to better understand where we are and where to go next, this is a set of questions to poll interests and opinions from users of curl and libcurl. The questions are mostly the same as last year and the year before that, to make it easier for us to see year-by-year changes. You answer anonymously, but please stay honest and fair. Answer only once per person. Just skip the questions you can't answer. The poll is open ten days until midnig...

I'll talk #http2 in the Mozilla devroom at #FOSDEM 2016!
At FOSDEM 2015 Daniel presented what the HTTP/2 protocol was going to become. It subsequently shipped to the world as RFC 7540, has been adopted by all major browsers, the most popular web servers and an ever growing number of sites. This is a recap of what the protocol is, what it means for ...

I figured I have too much spare time so I started to write a book about curl. Everything curl is the working title. You can help out!

What do you think about RFC 7686?
Curl sends DNS requests for hostnames with a .onion TLD. This leaks information about what the user is attempting to access, and violates this requirement of RFC7686: "Applications that do not imp...

Thank goodness we can't get http/2 in cleartext. Even if one ignored the privacy enhancements that encryption brings (which'd be a mistake,), then encryption still means we can evolve the protocol.

Cleartext means that proxies prevent the evolution of the protocol by making any evolution dangerous to a set of your users/customers.

Congestion Control Without a Startup Phase

This interesting research paper from 2007 indicates that removing the slow start from TCP might be doable and perform really well.

"For instance, a TCP connection using 1500 byte packets over a 10 Gbps network path with a RTT of 100 msec will ... require over 1.5 seconds to start fully using the available capacity. In addition, over 100 MB of data will be required to be transmitted before the cwnd is fully opened."

That would not surprise me either that there are more than one view on this and that different scenarios and tests will show different outcomes...

I particapted in the RFC 6265 process on the http-state list.

As the main author of curl and libcurl's cookie parser and logic, I completely sympathize and agree with what these drafts are set out to do and I will work on implementing them once we agree on the content.

At release 150, let's look back and see what new stuff curl got during the last 2 years. It is probably a little more than you knew...
We just shipped our 150th public release of curl. On December 2, 2015. curl 7.46.0. One hundred and fifty public releases done during almost 18 years makes a little more than 8 release per year on average. In mid November 2015 we also surpassed 20000 commits in the git source code repository.

copy as curl - your favorite browser already knows how to repeat a transfer with curl!
Using curl to perform an operation a user just managed to do with his or her browser is one of the more common requests and areas people ask for help about. How do you get a curl command line to get a resource, just like the browser would get it, nice and easy? Both Chrome and Firefox have ...

Found that out by accident one day.

Oh, and --trace was a life saver. One time, I was having trouble automating a login procedure to a website. It was only after I used --trace that I discovered that I was formating my data wrongly while using --data-urlencode

This post was not bought - completely without irony or sarcasm, just stating the facts here that while there are offers for me to sell out, I don't accept them.
At times I post blog articles that get the view counter go up to and beyond 50000 views. This puts me in a position where I get offers from companies to mention them or to “cooperate” on further blog posts that would somehow push their agenda or businesses. I also get the more simple offers of ...

Good service and a great atmosphere. We got to enjoy the sun slowly setting while sitting outdoors watching boats go by and enjoying delicious food. Highly recommended!

Lovely garden and pool area. The hotel has a set of pool toys my kids could spend a lot of time with. The only minor downside is the at times rather heavy traffic next to it.
