Recover access to a SQL Server instance. By: Aaron Bertrand | Read Comments (80) | Related Tips: More > Security Problem Starting with SQL Server 2008, the local Administrators group is no longer added by default during SQL Server setup; you even have to use a manual step to add the current user as a local administrator.
This means that it is possible, especially if you don't use mixed authentication (or have forgotten the sa password), that you can be completely locked out of your own SQL Server instance. I've seen cases where an employee has moved on, but their Windows account, being the only one with Administrator privileges for SQL Server, had been completely obliterated from the system. Of course that person was the only one who knew the sa password as well, and being a local admin or even a domain admin might not help you.
The typical workaround I have seen employed is to restart SQL Server in single user mode. Solution The process to get back up and running is quite simple. Caveats Conclusion Next Steps Last Update: 8/30/2012. Application Pool Identities. Introduction Whether you are running your site on your own server or in the cloud, security must be at the top of your priority list.
If so, you will be happy to hear that IIS has a security feature called the application pool identity. This feature was introduced in Service Pack 2 (SP2) of Windows Server 2008 and Windows Vista. An application pool identity allows you to run an application pool under a unique account without having to create and manage domain or local accounts.

[SOLVED] Logitech C270 and MJPG-Streamer. Hi, I have a Logitech C270 webcam connected to my RPI via a powered USB hub.
This camera has two operation modes (or capabilities): YUYV and MJPEG.As far as I could understand, the difference between both is that with MJPEG capability, the image is compressed in the camera itself before being sent to the host (in this case the RPI), while in YUYV, there is no image processing and the raw image is sent to the host. Application Pool Identities. How to Send Push Notifications from Raspberry Pi. This project demonstrates how to send push notifications from Raspberry Pi to iOS and Android devices using a free push app.
The idea is to trigger the event of sending the push message with a magnetic door sensor. When the door opens, the Raspberry Pi sends the message. The magnetic door sensor can easily be replaced in this project with some other type of alarm device such as a PIR motion sensor, infrared trip wire, or other. You can also setup your RPi to handle multiple sensors and push messages. REST API on a Pi, Part 2: control your GPIO I/O ports over the internet – The Floppy Disk. [SOLVED] Logitech C270 and MJPG-Streamer. Hi, I have a Logitech C270 webcam connected to my RPI via a powered USB hub.
This camera has two operation modes (or capabilities): YUYV and MJPEG.As far as I could understand, the difference between both is that with MJPEG capability, the image is compressed in the camera itself before being sent to the host (in this case the RPI), while in YUYV, there is no image processing and the raw image is sent to the host.
In practice this means that streaming in MJPEG mode uses less than 5% of RPI CPU while in YUYV the CPU goes to the top because the RPI needs to process the raw image and convert it to MJPEG before sending it out. I guess this kind of explains the difference between ~3€ webcams and 50€ branded webcams. Use a Raspberry Pi to remotely watch your home.

NodeMCU Firmware for the ESP8266. Introducing NodeMCU The NodeMCU Firmware is an open source project that provides an abstraction layer on top of the Expressif SDK for the ESP8266. While the SDK itself provides low-level access to the peripherals of the ESP8266EX chip, NodeMCU provides a high level API that hides a lot of the implementation details of how the chip works.
