Full node – Testnet Bitcoin connection refused (111)

I have ah Raspberry and I'm going to set up a BTC & Lightning node.

I have the AddNode from this thread:

The node synchronization with testnet3 is very slow

in the getnetworkinfo it says:

  "warnings": "Warning: unknown new rules activated (versionbit 28)"

and the debug log says:

2018-04-24 17:39:51 connect() to 85.207.214.190:18333 failed after select(): Connection refused (111)
2018-04-24 17:38:16 connect() to (2001:470:c144:cafe::a):18333 failed: Network is unreachable (101)

does anyone have an idea where the error lies?

my testnet port: 18333 is open.

many thanks for the help!

ios – No debug values ​​are displayed on xcode 11.1

I've had this problem for a few weeks, it got so annoying that yesterday I completely deleted and restarted my MacBook, but the problem still persists.

I have a framework (created by myself so I have the code on my computer) and an app (also created by myself for the code to be on my computer). The app uses the framework. I try to debug the framework, so I add breakpoints in the frameworks and set them to user so I restrict them while running my app.

The problem I have is that Xcode has no idea what value something has, as soon as I'm inside the framework code on a breakpoint. If I hover over a variable, I just get the name of the variable and if I use & # 39; po & # 39; from the console only states error: :3:1: error: use of unresolved identifier 'returnValue'
returnValue

The annoying part is that when I completely reset my MacBook for the first time and retrieved the code for my framework and app, I could easily debug and display everything. Now, just one day later, everything is suddenly gone, and it's no longer possible to see values ​​of anything. I know that nothing has changed in terms of project settings between functioning and non-functioning (on the app or the framework). I'm just making code changes and debugging works only once, not next time, the main problem is that it's pretty much always in a non-functional state.

I have reviewed all the important things that people have already said about this question to confirm:

  • I'm definitely building a debug version of the framework and the app.
  • Optimization is set to NONE for both the framework and the app

I use Xcode 11.1 and Catalina 10.15

I've reached a point where I literally can not continue my work because I can not debug anything anymore. I thought a completely new hard drive and reinstalling MacOS and Xcode might have fixed the problem, but unfortunately not …

linear algebra – What is the dimension of a subspace with vectors [1,1,1]?

Say $ S = {{(x, y, z): x = y = z} } $then every vector can be represented in S as $ s = lambda cdot begin {pmatrix} 1 \ 1 \ 1 end {pmatrix}: lambda in R $, vector $ s $ is there for each independent $ c cdot begin {pmatrix} lambda \ lambda \ lambda end {pmatrix} = 0 $ Equation holds iff $ c = 0 $, Likewise $ s $ extravagant $ S $ since every vector in $ S $ would be a linear combination of $ s $, What that tells me $ s $ is a base of $ S $ and $ dimS = 1 $, However, I can continue the decomposition: $$ s = begin {pmatrix} lambda \ 0 \ 0 end {pmatrix} +
begin {pmatrix} 0 \ lambda \ 0 end {pmatrix} + begin {pmatrix} 0 \ 0 \ lambda end {pmatrix} $$
These vectors are obviously independent and span $ S $ also. So $ dimS = 3 $but we just saw that $ dimS = 1 $, What is the correct answer? Many thanks.

tls – Why does mutual authentication work on openssl 1.1.0g, but not on openssl 1.1.1?

I submit an HTTPS request with mutual authentication. If you test it with curl 7.58.0 using openssl 1.1.0g, it works fine. After upgrading to openssl 1.1.1 with the same curl version, the call no longer works with an "inappropriate fallback" error.

When using Wireshark, the problem is probably due to OpenSL, which offers TLSv1.3 in version 1.1.1, but not in version 1.1.0g. The server only allows TLSv1.2. However, I give curl the option "–tlsv1.2" and openssl still seems to offer TLSv1.3 and TLSv1.2, for which the server refuses TLSv1.3 without fallback.

My question is if this is a known behavior change between versions 1.1.0g and 1.1.1 and what can I do to force openssl to use only tlsv1.2 with curl?

Many thanks,
Ian

PS: I've consulted the many change logs between 1.1.0g and 1.1.1, but I can not see the answer.

Can Python 2.7.16 be created with openssl 1.1.1?

I suppose Python (after some googling) does not use the installed version of OpenSSL, but instead uses its own SSL module and needs to rebuild it to update it.

This is on an ARM processor, by the way.

I've cloned the OpenSSL source from git, checked out the 1.1.1 Stable branch, and created it. only standard configure. do. to do a test and sudo make install,

Now I am trying to rebuild Python to use this version.

I got it to work with Python 3, but it fails in Python 2.
Both are tarballs downloaded today from www.python.org/downloads/source/ and created with ./configure and do without additional options.

Result for 3.7.3: make is successful, as is this test

$ ./python -c "import ssl; prints (ssl.OPENSSL_VERSION)"
OpenSSL 1.1.1d-dev xx XXX xxxx

The old (installed) version of Python reports OpenSSL 1.0.1t for Python and Python3, so the new build uses the new version.

Result for 2.7.16: make is only partially successful, but ends with

Error creating these modules:
_hashlib _ssl               

and the same test goes

$ ./python -c "import ssl; prints (ssl.OPENSSL_VERSION)"
Tracing (last call last):
File "", Line 1, in 
  File "/usr/local/src/python/Python-2.7.16/Lib/ssl.py", line 98, in
