Finding Careers In Technology

  When they ask me about a good VPN service, I don’t know what to say. The essence of all services is the same - hiding your IP and access to blocked resources. Someone does it better, and someone worse. As a result, the choice of service is reduced to the personal requirements of the questioner. I can only tell which service is worth a try. And in this article I will talk about ALTVPN. The name of the service stands for Alternative Secure Services, and in fact ALTVPN is an alternative VPN. Let's see why. On a separate page, you can get detailed instructions for installing ALTVPN on your device. I will not talk about manual configuration through PPTP or OpenVPN, everything is too individual here and requires experience. But ordinary users can download the application for their device. This setup takes literally half a minute. For example, on Windows, when starting the application, you just need to specify the user code, select the connection server and click the "Connect"...

Data lakes have become the cornerstone of many big data initiatives, just as they offer easier and more flexible options to scale when working with high volumes of data that’s being generated at a high velocity – such as web, sensor or app activity data. Since these types of data sources have become increasingly prevalent, interest in data lakes has also been growing at a rapid pace, as can be seen from this Google Trends chart: However, as with any emerging technology, there is no one-size-fits-all: a data lake might be an excellent fit for some scenarios, but in other cases, sticking to tried-and-tested database architectures will be the better solution. In this article we’ll look at five indications that should help you understand whether it’s time to join the data lake bandwagon or if you should stick to traditional data warehousing. But first, let’s set the parameters of the discussion by defining the term ‘data lake’.  Data lakes are excellent for storing large volumes of uns...

  Some smb shares on linux server works with Windows 7 and some has authentication issue.  All works with windows XP.  I had to set to "send LM and NTLM response" under local security policy for the client computer for it to connect to the linux file server.  Why do I have to set manually, why isn't this default on windows 7, and what would prompt some linux server to work and some to not? LM and NTLM version 1 are extremely insecure methods of password hashing. All versions of Windows and server include backward compatibility for older versions of Windows and applications. As we see newer operating systems (like Win 7) they will default to a more secure method to help protect the password hashes. Therefore, when using Windows 7 you will likely need to force it to use this backward compatibility if you are connecting to something that doesn't support the newer methods like NTLM v2 or Kerberos. As for your specific situation; are the Linux servers running different di...

  Network cameras, which are Internet Protocol-based cameras that transmit video data over a local area network (LAN), are becoming increasingly prevalent – especially in surveillance and security scenarios.  Windows now allows users to associate network cameras to their PC, enabling photo capture and streaming of video in camera applications. Currently Windows only supports ONVIF Profile S compliant cameras*, which are standards-compliant network cameras optimized for real-time streaming video capture. Note: The features discussed in this article are available with Windows 10, Insider Build 18995. Windows provides support for discovery, pairing, configuration and streaming via WinRT APIs. To discover network cameras connected to the local subnet, create a DeviceWatcher class and follow the instructions specified in this document, connect to remote cameras. Also find :   windows lan

  Data lakes are having a moment. According to one recent report, they are expected to grow by about 30% over the next five years. Tomer Shiran, CEO of data-as-a-service vendor Dremio, explains what they are, why they make sense in the cloud and how to make them work best for your company. Dremio has its own cred: Founded just five years ago, the company is routinely named to "best of" lists, including Pagan Research's list of "Most Promising Big Data Startups in the World" and CRN's "10 Hottest Big Data Startups of 2019." What is a data lake? It provides a united source for all data in an organization by replacing the many siloed file and object stores that hold collections of data that tend to spring up inside organizations. Data lakes are also inherently open, providing clear separation of storage from compute and processing, and provide a non-proprietary storage alternative compared to ingesting data into proprietary solutions such as data ware...

  Today’s networks need to support more traffic than ever. Employees access corporate data from desktops and mobile devices. Internet of Things devices proliferate everywhere on premises. Network designs and support strategies need to be adjusted to tackle these top challenges: 1.Poor network performance. There’s no question that poor network performance is a top challenge for network engineers. There isn’t simply more total traffic; there’s more traffic in all directions. Without the right equipment at endpoints and midpoints along the way, it’s impossible to provide the high-speed communication needed by today’s applications. Plus, performance isn’t just about speed; it’s about reliability, too. Network designs need to handle spikes in load and provide alternate routes to enable communication to continue even when a link fails. 24×7 online business requires 24×7 network availability. 2.Security. Security is another top challenge. Because the perimeter of today’s network is unclea...

  A VPN is a way to connect to the internet through an encrypted connection. When you access a website, upload data to an app or check your email, the VPN encrypts all your communications and sends them to a server run by the VPN provider, which then sends them on to their destination. That is useful for preserving your privacy when you don't trust the network you're on, whether it's an internet service provider or a Wi-Fi connection at an airport or coffee shop. You can also use a VPN to connect to a corporate network for work purposes. Many companies use this method to limit access to their internal networks to employees with VPN usernames and passwords and to encrypt their connections to work machines. How Does VPN Work? A VPN encrypts all the data you send from your computer across the internet, shapes it into specially formatted packets of data and sends them to the VPN server. The server has digital keys it can use to decrypt the data, but anybody else without these k...

  Just to give you a quick overview of why you would find this useful: On-demand access to files and resources on a network – you don’t have to keep a computer turned all the while. Energy efficiency, you will see a reduction in your utility bills since you don’t have to keep your system on all the time. Great for remotely managing a computer, so you can access a computer that might be across the room or upstairs. How does it work? With wake-on-LAN enabled, your computer will “listen” for a “magic packet” containing its MAC address while it is in sleep mode. The computer can be woken up by sending it a magic packet from another device on the network. Again, you can find out more about the feature here. What are the requirements? Your computer might not have all the requirements for this feature that will include the following: Ethernet connection. A peer to peer network between two or more computers. The computer must be in either Sleep or Hibernation mode for this to work. Also re...

  The Open Systems Interconnect (OSI) model for network communications establishes a layered approach to communicating between computers on a network. Each layer of this seven-layer model may have its own way of referring to the other computers with which it communicates. This means that any given network server may have many different addresses on file--for use with the different communications layers at work. Ethernet Working at layer two of the OSI model, all systems connected to an ethernet network will have a unique ethernet address. This address is expressed as a set of eight hexadecimal values, such as 00-2B-78-5F-03-8A. This address may be used by network switches and bridges to help constrain and route traffic to this particular server. Internet Protocol The Internet Protocol, working at layer three of the OSI model, establishes a unique IP address for every machine on the Internet. IP addresses have three parts: network address, node address and subnet mask. Though the or...
