As photographic processes advanced, photography took away painting's historic purpose of recording the world. The invention of photography in the 19th century greatly affected the course of painting. The genres were organized into a hierarchy, and include history painting, portraits, landscapes, still lifes, and genre painting. It has been used since antiquity, and examples from the first century AD still exist today.ĭuring the Era of Enlightenment, five genres of paintings were advocated by art academies, including the French Academy and the Royal Academy in London. Tempera paint was the preferred medium of choice in Renaissance Italy. ![]() Oil paint is a more flexible medium, and allows for a greater range of optical effects this in turn led to new expressive techniques for artists. It seems humans have been drawn to artistic expression for millennia. Some of the oldest known paintings can be found at the Chauvet Cave in France, which are estimated to be about 32,000 years old.ĭuring the late Renaissance, oil painting techniques were developed in the Netherlands, which quickly spread across Europe. Others specialize in a particular style, be it fine art, street art, or expressionist paintings.Īs the world’s largest online art gallery, Saatchi Art is thrilled to help people everywhere discover, fall in love with, and own one-of-a-kind paintings by some of the most talented emerging artists from around the world.įor a bit more help finding the perfect artwork from our selection of original paintings for sale, we also invite you to take advantage of our expert Art Advisory service.

If I go back and execute without the OPTION (RECOMPILE) then I will get the prior plan (to use the index). And, it will NOT affect future executions. ![]() It was used solely for the execution with OPTION (RECOMPILE). Using the same statement, I’ll again query the plan cache:Įven though this is the third time we have executed this statement, this final execution was NOT put in cache. I’ll go with answering #3 first as that one is easy to answer. What did SQL Server do with the plan itself?.Should this particular statement always be executed to recompile and never save a plan?.But, if we’re just talking about two different values against a single column, this would be guessing statistics of the data. Would someone really be able to programmatically guestimate that a parameter submitted from the client is “atypical” and/or that it warrants recompilation? And, I guess I can answer yes – for some parameters – like those with a wildcard.The query plan as a result of this execution is:Īnd, this is the more optimal plan given this parameter. SELECT = ‘SELECT * FROM dbo.member WHERE lastname LIKE OPTION (RECOMPILE)’ĮXEC sp_executesql varchar(15)’, ‘Anderson’ If we suspected this and/or knew this when we were executing (from the client) then we could use OPTION (RECOMPILE) to force SQL Server to get a new plan: Text varchar(15))SELECT * FROM dbo.member WHERE lastname LIKE 2Īnd, while we know that this plan (to use the index) is good for the highly selective value of ‘Tripp’ it’s is not good for the value of Anderson as there are many rows that match. In fact, we can see that from checking our plan cache as well: SELECT = ‘SELECT * FROM dbo.member WHERE lastname LIKE sp_executesql varchar(15)’, ‘Anderson’Īnd, we see that it uses the EXACT same plan (looking at showplan). ![]() We’ll execute the exact same statement again – using the value of Anderson just to get setup to the point where we were last week: Click on an XML showplan and SSMS will go DIRECTLY into a graphical query plan window (2008 onward):Īnd, once again, we see the optimal plan (to use the index and do a bookmark lookup) because this query is highly selective (only 1 row). And, if we’re interested in seeing the plan, we can remove the commented out cp.* in the query above to get the cp.query_plan column. So, what is this showing us… it’s showing us that there’s a plan in cache for this statement. Text varchar(15))SELECT * FROM dbo.member WHERE lastname LIKE 1 Now, we have a row for our parameterized query plan: SELECT = ‘SELECT * FROM dbo.member WHERE lastname LIKE sp_executesql varchar(15)’, ‘Tripp’ I’ll execute the following and then recheck the plan cache: SELECT st.text, qs.EXECUTION_COUNT –, qs.*, cp.*ĬROSS APPLY sys.dm_exec_sql_text(sql_handle) AS stĬROSS APPLY sys.dm_exec_query_plan(plan_handle) AS cp To see the combination of all of these things – I’ll use some of the DMVs that track plan cache and plan utilization. It also tells SQL Server that this particular plan is a “single-use plan” that should not be reused for subsequent users. If we know that a statement returns a varying amount of data (based on the parameters supplied) then we can use the SQL Server 2005 feature WITH RECOMPILE to tell SQL Server that the statement being executed should have it’s own plan created and that prior plans (if they exist) should not reuse the statement. Today, I want to address a few of the comments as well as continue with a few tips and tricks using these commands.įirst off – could we have helped the performance of the sp_executesql statement?

QBittorrent is available on a wide range of platforms and in over 70 languages. You can immediately upload the file or set as ‘Private’, which prevents the file from being distributed over a DHT network. You only need to choose the folder or file from the hard disk and complete accurate information in a few fields, such as web seed URLs, tracker URLs, and so on. The process is straightforward and doesn’t require you to possess any technical skills or knowledge. Interestingly, qBittorrent comes with another excellent feature, that is, to create torrent files. This allows you to stop downloads safely in case the VPN connection drops. You can even visit the advanced settings, and choose to bind the program to a specific network interface. You’re therefore able to download a file whenever it’s freely available. In case you’re worried about the bandwidth limit, qBittorrent lets you set a schedule. Additionally, the software lets you control peers, trackers, and other parameters by prioritizing specific files or rearranging the queue. As such, you can work on other tasks while the program downloads batches of files. Does qBittorrent support sequential torrenting?įor downloads, qBittorrent lets you activate sequential torrenting. Last but not least, you can even check qBittorrent Portable, which you can carry around in a USB drive. You can also change the maximum number of connections per torrent.

Moreover, the program comes with a wide range of features to ensure easy installation, basic configuration options, integrated libraries, and several other tools, such as Qt toolkit, Boost, etc. However, most of these platforms aren’t free and even lack advanced features or display too many advertisements.įortunately, you can download qBittorrent for free and not worry about advertisements. UltraTorrent and Deluge are two common choices. This works quite effectively over digital networks supporting lower bandwidth options.ĭue to the popularity and ease-of-use, BitTorrent has led to the creation of several platforms. Due to this, the load on the server and network are minimized. It allows multiple users or peers to become a group, actomg as a bunch of host servers for a single file. You can use BitTorrent to reduce the network and server impact of sharing large-sized files. Most of the time, users opt for this program when they want to transfer large-sized files, such as songs, video clips, movies, and other forms of content. It’s often used for sharing electronic files or data over the internet. How does qBittorrent work?īT or BitTorrent is a commonly used communication protocol for P2P or peer-to-peer file sharing. qBittorrent is the perfect alternative to expensive torrent software.

If you would like to know how to set up Kaboom.js from scratch in your code editor of choice, there is a short section dedicated to this at the end of the course.įor now, please head over to Replit and create your first Kaboom.js environment now by clicking here. It will also allow us to create sprites directly in the environment itself. This environment will save us from having to write the Kaboom lifecycle methods, such as initialising Kaboom or adding scenes. To get coding straight away, we will be using the Kaboom.js environment on Replit. How to Use the Replit Kaboom.js Environment Now that we have covered that, let's get to setting up an environment and getting through some Kaboom.js basics so you can then dive into the full video course! We will be covering these in the video too, so if you get stuck, please refer to the video course for help. We will end with a section about where you can share your games with one another, as well as how to use Kaboom.js in VS Code. We will then move onto creating a game of Space Invaders, followed by Super Mario Bros, in the same pre-configured environment.Īfter we finish both of these games, we will be building Zelda completely from scratch. In this course I will show you how to code a generic game using the Kaboom.js methods in a pre-configured environment. It also gets you coding without being disheartened after trying to wade through pages and pages of documentation – which is common in the game development process we see today. This simplicity allows you to get into the world of game development at a low barrier of entry. We are going to be using this library to simplify creating scenes, adding layers, creating sprites, dealing with actions and collisions, adding key events, debugging and much more.

![]() However, you’ll need to have the surveillance client software installed in your Windows or MAC machine. The reason we’re saying this is because you won’t need to buy a PoE injector or Switch. To be honest, getting your wireless IP camera to work on your PC should be easier than with the PoE security cameras. But then, that will be a lesson of another day. The same should work if you would like to turn your PoE IP camera wireless. You just need to build an access point in your PoE NVR using an external access point device. The hack will be much easier with a wireless NVR, but even the PoE models can work. ![]() So, you can mount in about any location of the compound for as long it can seamlessly communicate with the receiver.Īs for the question of connecting a wireless IP camera to the NVR, it’s totally possible if the recorder is compatible. ![]() Of course, there are power cables to worry about, but battery-powered wireless security cameras are 100% wire-free. It can also be analog radio frequencies (RF) like those used by the traditional baby monitors, or else WiFi access points.Īs we may have mentioned in our previous posts, wireless IP technology can truly come in handy in places incapable of wiring. The transmitter here comprises an access point at either 2.4GH or 5.8GHz frequencies. On its end, a wireless IP camera uses its built-in transmitters to send data to the receiver. So, you necessarily don’t need to plug in the power cable, apart from few scenarios. However, the Ethernet cable the camera uses for video also provides power. The main difference is that the former uses a wired channel to communicate with the viewing or recording device. Just as the name, both PoE and Wireless IP cameras are network systems.
![]() When a, b and c are real numbers, a ≠ 0 and discriminant is positive but not a perfect square then the roots of the quadratic equation ax 2 bx c = 0 are real, irrational and unequal.
