I am setting up DR.Racket for SICP. By following this guide
http://docs.racket-lang.org/sicp-manual /index.html?q=sicp#%28part._.Introduction_to_the__lang_sicp_language%29
But I am not able to download sicp package. Following is the error message I recieved after hitting install.
Resolving "sicp" via https://download.racket-lang.org/releases/6.11/catalog/
ssl-connect: connect failed (error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed)
Please explain what to do?
Apologies if I'm telling you things you already know: it appears that certificate validation failed while contacting the racket package server.
There are several things that could cause this, but I have a sneaking suspicion that you have some kind of proxy standing between you and the server that is rewriting your traffic. Is this possible?
One way to test this would be to try installing the package on a different computer, connected to a different network.
(FWIW, I just tested this installation myself, and didn't encounter this problem. So, at a minimum, it's not that the world is broken :).)

I have been trying to reissue SSL in namecheap.com. I have already created multiple CSR using MacOS Keychain (Both from the Philippines, and from Japan) and through AWS. However, when I get to the Review & Submit part I keep getting an error (screenshot below). Thank you for any assistance with this, as I have tried numerous methods, and I still could not update the SSL.
I have gotten in touch with namecheap.com, and their response is
"... the certificate has this issue due to a bug from our side that is connected to .ink TLD. ..."
It seems that this is a bug in their system.
If anybody gets this error, you might want to connect with namecheap.com, to see if this bug is still not fixed.
question: I have copied one of my julia project from local pc to a cluster using Linux. When I was trying to run instantiate in Pkg-REPL, ERROR: git repository not found at `https://github.com/JuliaRegistries/General.git occurred. And I have no idea.
enter image description here
what I have checked: I have entered status in Pkg-REPL and it seems everything is well; and there is only one direction logs under ~/.julia
enter image description here
so what caused the problem and how should I fix it? Thank you in advance!
I finally solve this problem by cloning from https://github.com/JuliaRegistries/General.git manually.
cd ~/.julila
mkdir registries and cd registries
git clone https://github.com/JuliaRegistries/General.git and get a new direction General
now I can instantiate without any error occurred!
I am not still clear why the error occurred when I clone this site automatically using instantiate, so this is still a question to be answered.
I'm not sure if these could be the causes, but:
Can the server connect to GitHub? i.e., can you ping www.github.com? It is possible that a work-based server is hidden behind some firewall. Of course, quite odd to not allow outbound traffic.
Also, on your server account, have you had your public key registered with GitHub? It's been a while since I've had to do this, but you may need to also set your username and e-mail address. An easy test would be to just try doing a git clone https://github.com/JuliaRegistries/General.git on the server and see if that is successful. If not, perhaps the error message that it gives will be helpful.
In our software, we are keep getting this warning/error message intermittently. Not sure how/why this message appears.
HTTP asio handshake failed: error:140000DB:SSL routines:SSL
routines:short read
I searched in the Internet, but the mostly the result pointing me to a VMware problem. Which not the case for me.
Until I found out that actually this error is thrown by OpenSSL that is used by Boost-Asio. I have downloaded the source code of OpenSSL/Asio/Boost but couldn't find this error code in the source. My question, Is there anyone knows what this error means? What could be the trigger of this error message? I just want to understand a bit to find out the reproduction. So we can fix our software if there is any hole in the software.
Many Thanks in advance!

how to clean boost::asio::ssl::stream after closed by server
A commit in OpenSSL removed the error SSL_R_SHORT_READ.
The commit before before OpenSSL removed the error SSL_R_SHORT_READ still has it defined as 219 == 0xDB. This error of 0xDB is what comes out of OpenSSL as 0x140000DB.
In general a short read happens on TCP when the connection ended before the other side could send enough data to decode the current message. This may happen for example because the other side crashed or a network problem.
Found the root cause for my problem. There is mismatch of cipher the host and the client that trying to connect to. Then this error is thrown from the client.
I am trying to add Apache Nifi in ambari but continuously failing with error Error occured during stack advisor command invocation:
Unable to delete directory /var/run/ambari-server/stack-recommendations/1.
There is a similar thread with the same error in hortonworks community, I have tried everything mentioned in that thread but unable to fix it. My sandbox is installed in vmware workstation 12 player. I also tried to create and remove directory manually but it is failing with the error invalid argument. Created a thread for this error also on stackexchange. Please help!!!
Here is a link to Hortonworks forum thread. And it seems like sandbox is just broken:
This is due to a docker issue in this 2.5 sandbox build. It will be
fixed in next revision of the sandbox.
There are also some workarounds described (like use older HDP 2.4 or establishing own cluser based on the HDP 2.5 docker image)
Updated sandbox arrived: http://hortonworks.com/downloads
Trust me, active member of community see your posts in multiple locations. In a good, no Big Brother ways :) but cross-posting is an old as world ... Well, you got it.
Did you see a notice for this service in Ambari? Telling it's been deprecated? Same note in the github. There's a good reason for that, it's now been implemented properly by the dev team and with many more features. I.e. all the action is there now.
I think I replied a similar question, though not sure it was yours, take a look in HCC.
How to connect to MySql using Connector/c++ over SSL?
I read about mysql_ssl_set(): seems to work only with Connector/c.
I have openSSL enabled and working for require SSL users on MySql. And I can connect remotely to MySql using Connector/c++, but cannot see how to modify parameters of sql::Connection to reference certs for SSL.
Excellent tutorial from Giri Mandalika at MySql DevZone and docs on Connector/c++ don't mention SSL, which surprised me because SSL is well documented for Connector/c...or did I miss something obvious?
I realize sql::Driver::Connect() is overloaded, with the less-commonly discussed method taking one parameter sql::ConnectOptionsMap &options. Following that trail, I found just one discussion on point: Ulf Wendel/Thomas Pollak question-and-solution here (http://forums.mysql.com/read.php?167,367519,369534#msg-369534).
Did not work for me: when I incorporated it and tried to build (VC2008, WIN7) the build had warnings and failed.
I traced the exact causes as:
sql::ConnectPropertyVal generates locally defined symbol warning; and
std::map causes fatal error LNK1120: 1 unresolved externals.
With so many users out there of Connector/c++, I hoped others in the community might also be interested in how to use SSL with Connector/c++. Appreciate any ideas or help.
Spoke to Giri Mandalika (on the original development team), who mentioned that SSL support was originally planned but not completed for Connector/c++.
In case others who want SSL find this question, I worked around the problem only by using Connector/c, the underlying C api which Connector/C++ was designed to wrap.
As more than six months have elapsed without any community member coming up with a specific solution to use SSL with Connector/c++ (other than the overload solution referenced in my question), I guess I have to conclude that it just isn't possible, and mark my own question as "Answered" by me.
