Numark DJ io timed out driver install error

Problem was quite easy to solve, if you are installing this usb external soundcard under xp, you probably need for sure attach the external 5-6v DC supply. Even more, its recommended to always use dedicated external power supply or 1amp from an USB 3.0 port. Drivers provided by numark on the net we're fine, trouble was this annoying card is power hungry. Specs tells you about a 6v 1A so you can imagine it is not something optional. Amazing mis info from the manufacturer, almost no support from them and we don't know what chip it uses.

VPN server, Windows 8.1 no funciona.

Problema: Al conectarse desde un smartphone o una pc aunque conecta (50% de los casos desde android) la conexion carece de toda funcionalidad, no se pueden acceder a archivos compartidos ni a escritorio remoto ni mucho menos el cliente puede utilizar nuestra conexion para su privacidad.

Test 1 -  Agarramos un notebook con windows xp y creamos una nueva "incoming connection", los unicos parameros que cambiamos son que el rango de ip del cliente sera del 192.168.0.20 al 192.168.0.30 (el primer lugar es asignado al equipo servidor de la VPN).

Para probarla de manera rapida y sencilla solo usamos el nombre de equipo en la red como direccion ip y para ver si funcionan los archivos compartidos ponemos la ip del servidor que es \\192.168.0.20.

Resultados: Funciona todo menos la conexion a internet.

Test 2 - Volver a crear la VPN Incoming Connection y desactivar el firewall de windows 8.1 en su totalidad. Ahora si funciona la conexion pero es inseguro dejar el firewall apagado teniendo un router con upnp activado, si un virus entra puede usar upnp para abrir el puerto que necesite y destruir nuestro sistema.

Test 3 . Probando conectividad desde el celular
Despues de varios intentos y de haber desconectado el usuario activo pc a pc primero que todo, el dispositivo android del cliente ya esta conectado a la red VPN y puede acceder a su sesion de escritorio remoto en caso de que solo ande compartir archivos o impresoras.

Conectar un segundo router a un router en puente / bridge (Usando AR-Link Rio Gallegos)

Basicamente solo debemos hacer dos pasos para conectar un router a una red ya existente, desactivar DHCP y cambiar la ip del router secundario. Para este caso nos basamos en el Cablemodem WI-FI Router provisto por el servicio de fibra optica AR-Link disponible en Rio Gallegos, Argentina. Es curioso que este servicio nos provea de 10 megabits por segundo de navegacion (10 Megas / Mbps) cuando el estandar hasta hace un año o dos era el pesimo servicio de Speedy / Telefonica con 512kbps de subida y 1mbps de bajada.

El primer paso es desactivar el DHCP en el router que queremos usar como secundario, una vez que hagamos esto al conectarnos a este router ya no va a responder salvo que tengamos la conexion ethernet lista. Pero para no complicarnos mejor hagamoslo todo paso por paso.

1) Conectemos el router secundario a la corriente y encendamoslo.

2) Para configurarlo necesitaremos preferentemente una notebook conectada a este router a uno de los 4 puertos LAN (no al WAN!)

3) Ingresemos en la notebook usando el browser la direccion ip del router para entrar al menu.

4) Busquemos entre las opciones de red LAN el servidor DHCP del router y desactivemoslo.

5) Una vez desactivado ya no podremos seguir configurandolo hasta que no establezcamos una ip manual en la conexion LAN de la notebook. En este caso usamos un router ENCORE de 150Mbps y la ip manual que usamos es 192.168.0.117. Los demas parametros no son necesarios configurarlos.

6) Ahora cambiemos el segundo parametro en el router, su direccion IP predeterminada, este paso es necesario para que podamos configurar los dos router las veces que necesitemos y no se superpongan las IP de configuracion por el navegador predeterminadas que suelen ser 192.168.1.1 o 192.168.0.1. En este caso el cablemodem utiliza la ip 192.168.0.1 asi que le asignaremos al router secundario la ip 192.168.0.254

7) Por ultimo desconectemos la notebook del router y conectemos ese extremo de cable de red a uno de los 4 puertos del cablemodem.

8) Ya deberiamos tener internet en el router secundario, por si acaso reiniciemos uno o ambos router.

Setting Up a IIS FTP server on Windows 8.1 (Quite Hard!)

As it was in Windows XP, just a few clicks to create an IIS FTP server but this is not the case, although you needed Windows CD-ROM, or the other way around, with Windows 8.1 you don't need any disk but the process is not the same and it may lead to "bugs" if not done properly.

1) Turn on Windows Features or on
2) Mark whole FTP Server and within "Web Management Tools" mark "IIS Management Console", "IIS Management Scripts and Tools" and "IIS Management Service".
3) Now open the IIS Management Console, in this case I use ClassicShell for a classic start menu, is highly recommended.
4) Right Click to add a new FTP Site and fill the boxes with this info, I don't feel very safe sharing through ftp the whole drive.
5) Next step is very important, we don't wanna mess with advanced features, just put basic authentication or you won't be able to log in:
6) to be continuated

Discovered how to fix unspecified error installinc vc_redist for OBS Studio 32bit

Windows 8.1 x64
After trying several things to install the newest version of OBS Studio, a software for live streaming, it appears that solution has been found. Install the UNIVERSAL C RUNTIME.
The files for this were really hard to find, but we found them in an Adobe Premiere support one.

I don-t know what for 64bit version of obs is, for now 32bit is working normally.

https://helpx.adobe.com/es/creative-cloud/kb/vc2015_update.html
Mirror>https://drive.google.com/drive/folders/14w6Xlu8ujYhry8YRFQtUrhvjY1QB9vBr?usp=sharing
A will post a mirror for these files, they are around six update packages, updating windows didn-t work for me. Also tried refreshing windows by recovery options and even reinstalling whole system. It-s a lot of less work that windows can install over the same drive letter unit and sizes are not added, it is supposed that a windows install will not take less thatn 20GB, I had little free space but when installed windows I didn-t get out space error.

Jamas uses Cortar y Pegar (Cut and Paste) al transferir archivos al PC - Android.

Si creiamos que manteniendonos en la memoria interna de los moviles android estabamos seguros, nos equivocamos. Mantenernos lejos del almacenamiento basado en microSD cards es inseguro, pero en la memoria interna tambien pueden ocurrir bugs que lleven a la perdida de informacion. Como es el caso del telefono que usaremos como ejemplo para intentar buscar una solucion, donde la ultima opcion es rootear y hacer un "dump" de la memoria interna a nuestra pc con complicadas herramientas de linux en sus versiones windows. Herramientas tales como busybox y cygwin que nos permiten teniendo el equipo rooteado hacer un volcado de memoria mediante un protocolo local de red.

La situacion con nuestro movil fue, quisimos liberar espacio cortando la carpeta DCIM a nuestro ordenador o mejor dicho a una ubicacion de red y un bug hizo que windows entendiera que el proceso ya estaba finalizado y la carpeta se borró como sucede en todo cut and paste. Ahora nuestros archivos importantisimos se han ido y estamos probando distintas herramientas como el novedoso dr. phone que parece estar haciendo el trabajo necesario, para toda operacion de desarrollador el primer paso siempre es habilitar el modo de depuracion usb o usb debugging, proceso sencillo que incluye tocar varias veces en "build" en opciones del telefono.

Case 2: Android phone does NOT connect as a hard drive
Recent Android phones and tablets, especially those without an SD card, do not connect as a hard drive, but as a multimedia player. The icon that appears in My Computer is different, and there is no drive letter .
You can force an Android phone to connect as a hard drive ( mass storage ), but it is a very complicated procedure, since it involves rooting (unlocking) the device and using difficult-to-use utilities." https://www.quora.com/How-can-I-recover-the-files-that-lost-during-cut-and-paste


Probando dr.fone para android -  FAILED ON MOTO G5 32GB 5TH, segundo intento: ROOT FAILED


En este momento el telefono se ha reiniciado luego de supuestamente hacer un "root" temporal y desbloqueamos la pantalla, sin embargo nada ha pasado... Al cabo de unos momentos aparecio una leyenda de "connectiing..." y de nuevo volvemos a la pantalla de inicio donde seleccionamos el tipo de archivos a recuperar y nos pide hacer un root otra vez, parece que esta utilidad aunque es bastante avanzada y usa la tecnica correcta no es capaz de recuperar nada, detecta y todo, pero estamos de vuelta en la pantalla de inicio.

Ahora nos enteramos que desde android 6 los telefonos vienen encriptados por defecto! Uhy y ahora como hacemos para y si es que llegamos a tener que usar cygwin? Si "dumpeamos" una imagen encriptada de la memoria interna no podremos recuperar nada!

ALTO! Hemos leido que dr.fone puede ser scam o simplemente es un software poco fiable, algunos usuarios han reportado incluso brick de sus moviles! No seguiremos adelante con esta prueba porque no queremos que no solo no recuperes tus fotos o videos sino que tambien brickees el movil.

"Problem 1: Galaxy S7 edge stuck in bootloop after stopping Dr. Fone software installation

Hi. I have a problem with the Galaxy S7 edge (SM-935F) of my mother’s. She accidentally deleted some photos and I wanted to get back those photos using an Data Recovery Software (Dr.Fone). While it was in Download Mode doing its thing (hasn’t started analyzing yet, just installing some recovery package), it stuck at 100% for a long time and couldn’t go on. So I wanted to abort it (I think I restarted the phone because there wasn’t a stop function in the program, but not sure anymore what I exactly did), and now it stucks at the samsung logo. I tried so much, I went to download mode and tried doing it again and fixing with functions given by Dr. Fone. I did soft restart so often, I restarted it when going into download mode (you can choose if you really want to go into download mode or restart), I can’t get into soft mode. I restarted it from recovery mode, I wiped the cache partition, I also wanted to try FonePaw but it doesn’t support this phone.
Now I’m helpless because I don’t want to do a factory reset. All I need is to somehow get those deleted photos. After I got those I can do a factory reset because there isn’t anything other important stuff on it, only those photos. So a solution with using the download mode and a PC to get those photos without fixing that the phone can’t start properly would also be great for me.
I can go into download mode & Recovery Mode, but not start it normally or in safe mode. I live in Switzerland and am not quite sure on the Android version, but I think it is Nougat. Best regards. — Arbenit Kamberi
Solution: Hi Arbenit. One of the surest way to brick a phone is to interrupt it while it’s installing something, be it an app or a new operating system version. Sometimes, installations can take several minutes depending on the software or app being installed. The intentional interruption that you did may have corrupted the storage device. This often occurs if an installation that involves scanning an entire drive is stopped prematurely. We don’t know how Dr. Fone’s software installation works but most probably, it requires a complete drive scanning since it’s a recovery software. Software of this type can take a long time to install since it needs to read the entire storage device for bits and pieces. Any good recovery software has to be thorough in order to read broken bits and combine them with others to form as recoverable files.
Terminating the entire scanning/installation process is not a good idea at all. It’s the same catastrophic situation that result if you stop or interrupt an Android system update. That’s why it’s recommended that you back important files up and ensure that the phone has enough battery before installing an update. Whether a user turns the device off, or the phone simply turns off due to low battery, the result is always the same — either the phone gets stuck in a bootloop, or the storage device becomes corrupted (complete hardware failure). Unfortunately, either of the two resulting situations require drastic solutions to fix, which in your case, means that you should try factory reset or flashing.
To see if there’s another way to fix the problem without resorting to factory reset or flashing, we suggest that you contact Dr. Fone technical support. We are not very optimistic about other options but you should give it a try."

Facebook and its common advances against the freedom of speech

If you posted your net radio stream url / ip, now you are done. Zuckerberg has decided to suppress every post without any warning containing a shoutcast stream ip.  The post is:

"Now playing 24/Nov 11:00p.m. (GMT-3) "THE RUSH" 303, by the American DJ PESTY a.k.a. Steven Hardy.
To listen NetRadio ENERGY (Argentina);
1) Visit with your android phone the address http://emisoraenergy.listen2myradio.com/ so you can listen to the radio directly from the web!
2) Or with the link http://162.210.196.145:3137/listen.pls using VLC for Android. Also works for Winamp and Windows Media on PC. (In Windows 8.1 *.wpl is not working if no codec pack like K-Lite is yet not installed)

Desktop Version URL: www.nrg.dx.am
Mobile Version Tiny URL: www.nrg.dx.am/m (This don't work in a PC browser)
nrgmultimedios@gmail.com
Warning: Several posts from August to November had disappeared, we think facebook censoring us because between those months we attached a request for solidarity for a kidnapped child of our resident DJ, Avionics and this social network supports everything related or against the left wing agenda"

We were wondering last days what happened to our posts between August and November and in a shortly investigation we discover if we exclude the stream ip of Net Radio ENERGY (Argentina), the post pass, if not, you get:

"Sorry, something went wrong.

We are working on it and we'll get it fixed as soon as we can."

Shoutcast IP Address. (m.facebook.com)(img.1)
But at the time we are writing this article now we are getting an specific error! It depends whether you are posting using m.facebook, if you include only the ip address of the shoutcast stream or add some text like "test".

But, hold on why are you posting using the mobile version while using a full desktop PC? Weeell, is quite obvious programmers make scripts and software every time and every day more dense and worse optimized and at the time of writing this article (11/24/2018) it's almost imposible to view anything within facebook on desktops. It does not matter if you are using Chrome or Firefox, loading times are ridiculously slow. Perhaps if you have +10mbps internet connection and high-end PC or laptop, only if you have that, perhaps you will be able to view and use the desktop version of Facebook Social Network. Not even say that the entire website has almost the same million lines of code as Windows 10. In our case we are writing using a modest laptop with a dual core Intel CPU and 4gigs of RAM, you can even play Half-Life 2 without any problems!! But facebook? Don't talk about it! Nowadays vast majority of users visit the website by the app for Android and iOS. Do you wanna hear more? If you post too much text in there, lags becomes a problem. In the case of the adverts of weekly podcasts of our net radio, the text is already a copy and paste where little things are being modified or edited every time.
