  Find apps blocking APK install button

I had a problem the other day.. Android has a protection against malicious apps doing overlay (screen filters, buttons etc); when installing custom APK, you can't press Install button. On my phone I had to install an app to list all apps having the overlay permission, specifically this:

Code:
Advanced Permission Manager
https://play.google.com/store/apps/details?id=com.gmail.heagoo.pmaster
After filtering which apps could do that, I was able to pinpoint the problem app and use Titanium Backup to freeze it (check if it is the guilty one).

I'd be happy if you could share what apps you've found out could do that for others to know.
Thanks.
In my case it was Lux Auto Brightness (1.75) [CM 12.1/Android 5.1]; after I upgraded it, the problem has disappeared (it disables itself automatically when an installation is detected).

  How to print business cards better

You likely have an image of your business card in resolution 9x5cm (300 DPI) from Photoshop.
Now how to tile the image to make them fit on A4 page as many times as possible?

Install ImageMagick and use the attached batch script.
It takes the source image, duplicates it to 3x4 grid to make them fit 12 times on one A4 page. They are easy to cut, with borders as guidelines around them.
Just make sure to set the same DPI before printing, to retain the 9x5cm dimensions.

  Replace in files (CLI)

A CLI script that replaces strings in files - recursively in multiple directories.
Files are filtered by *.txt filesystem matching convention, optionally directories are recursively traversed.
A text is replaced with another one, case sensitive.

The advantage of this over sed is you don't have to enter escaped regexps and worry about the results and you also don't need to enter parameters, you are asked each time.

On Windows you need to install cygwin first.

  Ping, traceroute and nslookup shortcuts

In Windows extract these files to your \Windows folder.

.zip net utils.zip Size: 1,5 KB  Downloads: 696


In linux append this to your ~/.bashrc file:
Code:
alias p='ping'
alias pp='ping -s 1024'
alias p4='ping'
alias pp4='ping -s 1024'
alias p6='ping6'
alias pp6='ping6 -s 1024'
alias t='traceroute'
alias tt='traceroute -n'
alias n='nslookup'

Guide


p pings using default stack
pp pings using 1kB data
p4 forces IPv4 (pp4 1kB data)
p6 forces IPv6 (pp6 1kB data)
t makes a traceroute (you can use first parameter -4 or -6 to force stack)
tt makes a traceroute without resolving names (-4, -6)
n resolves a name to IP address

  WiFi stops working after Android phone deep sleep

I've had this problem for almost a year. When using WiFi with CyanogenMod 11 (Android KitKat 4.4.4), the phone lost connection to WiFi and no data came through even though it looked connected (the phone didn't use mobile data, because it was still connected to "faster" WiFi). Some apps drained the battery even more waiting for data and keeping the phone more awake (mostly waiting for position acquisition using Google geolocation).
The problem was caused by WiFi router configuration where I use latest OpenWRT. The damned WMM mode (some special kind of QoS for multimedia) was causing this, and after I turned it off, there were no more lock-ups. From what I've read, there is a bug in Android sources that causes this and nobody bothered to fix it so far.

  OpenVPN configuration for LAN gaming

To be able to play LAN games over OpenVPN tunnel, please follow OpenVPN manual and create your unique certificates, one for server and one for players.
Also create one additional certificate using openvpn --genkey --secret tls-auth.key for handshakes.

On the server machine you also have to open the port in public IP / redirect the port to your internal PC.
The situation is as follows: a minimum of two players both have Windows, at least one has to have public IP/open port (42222). All other clients connect to him and they make a fast and secure virtual LAN network for games. None of them uses the chosen IP range for local network, in this example 10.5.5.0/24.

Use this server config:

Code:
port 42222
proto udp
dev tap
tun-ipv6

tls-auth tls-auth.key 0
ca       lan-ca.crt
cert     lan-server.crt
key      lan-server.key
dh       lan-dh2048.pem

tls-version-min 1.2
cipher AES-256-CBC
auth SHA256
tls-cipher TLS-ECDHE-RSA-WITH-AES-128-GCM-SHA256:TLS-ECDHE-ECDSA-WITH-AES-128-GCM-SHA256:TLS-ECDHE-RSA-WITH-AES-256-GCM-SHA384:TLS-DHE-RSA-WITH-AES-256-CBC-SHA256
remote-cert-eku "TLS Web Client Authentication"

server 10.5.5.0 255.255.255.0

server-ipv6 fc11:0:1054::/64
push route-ipv6 fc11:0:1054::/64

duplicate-cn
keepalive 10 120

comp-lzo
persist-key

route-metric 1
route 0.0.0.0 0.0.0.0 10.5.5.1 10001

push "route-metric 1"
push "route 0.0.0.0 0.0.0.0 10.5.5.1 10001"

client-to-client

status status-server-lan.log 60

and this client config:
Code:
remote 111.111.111.111
float

tls-client
port 42222
proto udp
dev tap
tun-ipv6
nobind

resolv-retry infinite

tls-auth tls-auth.key 1
ca       lan-ca.crt
cert     lan-client.crt
key      lan-client.key

tls-version-min 1.2
cipher AES-256-CBC
auth SHA256
tls-cipher TLS-ECDHE-RSA-WITH-AES-128-GCM-SHA256:TLS-ECDHE-ECDSA-WITH-AES-128-GCM-SHA256:TLS-ECDHE-RSA-WITH-AES-256-GCM-SHA384:TLS-DHE-RSA-WITH-AES-256-CBC-SHA256
remote-cert-eku "TLS Web Server Authentication"

pull dhcp-options

mute 10
comp-lzo
verb 1

Change 111.111.111.111 to match your server's IP. The predefined routes will take care of priorities and in most games the players should see each other and the server.
Just one more thing - you need to make sure the virtual device is given the highest priority (even above LAN or WiFi). You can do so by renaming your OpenVPN TAP network adapter to "OpenVPN" and running these commands from command line:
Code:
netsh int ipv4 set interface OpenVPN metric=2
   netsh int ipv6 set interface OpenVPN metric=2

I recommend creating gameserver on the server machine to minimize latency. And the very last thing would be to add the network range to trusted networks in your firewall (once and for good).

  Windows 7 - přepínátko priority mezi IPv4 a IPv6

V přiloženém ZIPu jsou dva reg soubory pro modifikaci registru Windows. Jeden nastavuje prioritu IPv4, druhý zpátky na IPv6, tedy pokud máte dualstack spojení internetu, můžete si zvolit, které spojení se má používat prioritně. Po aplikování je nutný restart systému.

V případě tunelování IPv6 nebo pokud potřebujete používat VPN spojení, které je nakonfigurováno čistě v IPv4 k sítím, které jsou zároveň dostupné i přes IPv6 se to může hodit.
