tengo un problema muy raro y la verdad no se por que. Intento enviar un parámetro usando Jquery y Ajax llamado “idCategory” a un controlador en Spring pero a la hora de enviarlo sale esto en la url:

Les agradecería su ayuda para solucionar este problema, muchas gracias.

I wrote a guide to corrupt Bitcoin Wallet recovery. Yes, you should use pywallet. It can dump the private keys from your wallet to a file even if Bitcoin Core fails to salvage it. You can then import them into a new wallet.
Dump the wallet with pywallet to extract the private keys:
python pywallet.py –dumpwallet > wallet.text --passphrase= PASSPHRASE
Now find the address containing your Bitcoins and sweep the private key.
I am add a custom repository config in CentOS 8 like this in my kvm virtual machine like this:
[root@localhost ~]# cat /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=http://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=http://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
http://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
but when I using this command to install kuberentes component, it shows me like this:
[root@localhost ~]# yum -y install kubelet kubeadm kubectl
Warning: failed loading '/etc/yum.repos.d/kubernetes.repo', skipping.
Last metadata expiration check: 0:37:38 ago on Sun 05 Jul 2020 08:38:19 AM EDT.
No match for argument: kubelet
No match for argument: kubeadm
No match for argument: kubectl
am I missing something? what should I do to fix this problem?
I am dual booting Windows 10 and Arch Linux. I installed Arch with GRUB2 first, then Windows, then created a bootable rEFInd USB, made sure each of its three options (Windows, GRUB, Arch) booted correctly, then hit install to disk. Well, apparently, it didn’t install correctly because (a) starting up without the USB launches GRUB, and (b) selecting rEFInd from the new USB option boots Windows; it shows:
Starting bootmgfw.efi
Using load options ''
Here’s the directory structure of the boot partition. First, a basic overview:
# mount /dev/nvme0n1p1 /boot/efi
# tree -L 3 /boot/efi

What should I do? I’d be happy to post more info, but this is all I know might be relevant. Thanks in advance.
I was having fun modifying a code given to me as an answer to a previous problem here, courtesy of user Alex Trounev (Thank you again), when I encountered a certain error which I had never seen before.
Here is the aforesaid code :
(*parameters*)
r0 = 0.5;
h = 1;
(Alpha) = 0.8;
(*region definition*)
reg = Cuboid({.5, 0., 0.}, {1., 2 Pi, 1.});
reg3D = ImplicitRegion(
r0^2 <= x^2 + y^2 <= 1 && 0 <= z <= 1, {x, y, z});
(*equation + conditions*)
eq1 = D(u(t, r, (Theta), z),
t) - (D(u(t, r, (Theta), z), r, r) +
1/r*D(u(t, r, (Theta), z), r) -
1/((Alpha)^2 r^2) D(u(t, r, (Theta), z), (Theta), (Theta)) +
D(u(t, r, (Theta), z), z, z));
ic = u(0, r, (Theta), z) == 1;
bc = DirichletCondition(u(t, r, (Theta), z) == Exp(-5 t), r == r0);
nV = NeumannValue(1, r == 1);
pbc = PeriodicBoundaryCondition(u(t, r, (Theta), z), (Theta) == 0,
TranslationTransform({0, 2 (Pi)*(Alpha), 0}));
(*solution computation*)
sol = NDSolveValue({eq1 == nV, ic, bc, pbc},
u, {t, 0, 2}, {r, (Theta), z} (Element) reg);
(*frames=Table(DensityPlot3D(sol(t,Sqrt(x^2+y^2),ArcTan(x,y),z),{x,y,
z}(Element)reg3D,ColorFunction(Rule)"Rainbow",OpacityFunction(Rule)
None,Boxed(Rule)False,Axes(Rule)False,PlotRange(Rule){0,1.5},
PlotPoints(Rule)50,PlotLabel(Rule)Row({"t =
",t}),ColorFunctionScaling(Rule)False),{t,.05,1,.05})
ListAnimate(frames)*)
When I run the code, after some time, I get greeted with the following error :
NDSolveValue::nlnum: The function value {$Failed} is not a list of numbers with dimensions {39639} at {t,u(t,r,(Theta),z),(u^(1,0,0,0))(t,r,(Theta),z)} = {0.0138161,{<<1>>},{-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,<<15>>,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,-4.66626,<<39589>>}}.
When I click on the three dots next to the error, I don’t find any information on the error like it’s usually the case. I then decide to google some answers.
I found some answers here while also trying to comprehend the error by looking at this and finally that answer here.
So if I did understand it correctly, such error arises when you use NDSolve (or NDSolveValue) to get a symbolical solution to your equation, but problems come up when you try to numerically evaluate it for plotting purpose, or when trying to get a symbolical result with a function that requires numerical values ?
In any case, I do not really understand why I get such error as my plot part is currently between (* … *) so it shouldn’t matter. As for the rest of the code, I do not really see an error but I am just a beginner so…
Anyway, can a kind fellow enlighten me please ?
A fairly new MS Windows Server 2019 VM installation is logging over a hundred Security Log Audit Failures a day with Event ID 4625.
RDP for the server is enabled only for a single trusted WAN source IP through the Draytek Firewall.
The server hosts 2 local applications and an on-premises Exchange Server. The PDC is another VM on the same physical bare metal Hyper-V Core host.
The Account Names, Source IP addresses and Workstation names appear to be quite random, though the workstation name “workstation” appears quite frequently.
An example log entry is:
An account failed to log on.
Subject:
Security ID: NULL SID
Account Name: -
Account Domain: -
Logon ID: 0x0
Logon Type: 3
Account For Which Logon Failed:
Security ID: NULL SID
Account Name: Hp
Account Domain:
Failure Information:
Failure Reason: Unknown user name or bad password.
Status: 0xC000006D
Sub Status: 0xC0000064
Process Information:
Caller Process ID: 0x0
Caller Process Name: -
Network Information:
Workstation Name: workstation
Source Network Address: 40.117.34.82
Source Port: 0
Detailed Authentication Information:
Logon Process: NtLmSsp
Authentication Package: NTLM
Transited Services: -
Package Name (NTLM only): -
Key Length: 0
This event is generated when a logon request fails. It is generated on the computer where access was attempted.
So my immediate thoughts are:
I’m kinda shitting myself right now as we’ve only just installed this server to replace an old Windows Server 2011 that got hit by ransomware.
I’ve heard about using programs like IPBan, but that would only seem to make sense if the attempts were from the same IP. In this case they seem to be from random addresses.
Would I be right in thinking having the necessary ports open for the Exchange Server (80,443,587) is the only reason these attempts from WAN IPs are even reaching the server? Is there anything I can do to prevent these log-on attempts from reaching the server or is this a level of intrusion to be expected when running an Exchange server?
i was trying to install Steam on my Ubuntu 15.04, and after trying unsusccesfully to install it through the terminal, i just searched through the software center and tried to download it, but it says “failed to download respository information. check internet connection”. i tried to upgrade my ubuntu to 16.04, tried to change my software sites in “software and updates” and nothing. i dont have any idea how to solve this, so here goes the details of the error when i try to install Steam:
ALSO: i cant install it through the .deb archive; it says
“dependency is not satisfiable: libnss3 (>=2:3.26)
i tried everything, but theres always some kind of error… please help!

Estoy enviando la siguiente cadena "Búsqueda no encontrada" al enviarla sin la ú la toma perfectamente, pero cuando va con ú sale el siguiente error:
Uncaught DOMException: Failed to execute ‘atob’ on ‘Window’: The string to be decoded is not correctly encoded.
El codigo js es el siguiente:
w._getParameterByName = function (name) {
name = name.replace(/(()/, "\(").replace(/())/, "\)");
var regex = new RegExp("(\?&)" + name + "=((^&#)*)"),
results = regex.exec(location.search);
return results === null ? "" : atob(decodeURIComponent(results(1).replace(/+/g, " ")));
};
Agradezco su ayuda
