Why is that? Because the iron has the same nature as the magnet. If you swung that magnet across the ground, not every piece of metal would rise – only that which was made of iron. ![]() In that scrap yard, there was a great magnet on a crane that would pick up metal. Now, what does a scrap yard and the rapture have in common? Well, let me illustrate. ![]() The picture of this coming promise reminds me of a metal scrapyard near my childhood home. The Greek word for this is harpagδsometha and it means a catching away. First Thessalonians 4:16-17 says, "For the Lord Himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord."Ĭhristians refer to being caught up as the rapture. In the twinkling of an eye, Jesus is going to step from His throne in glory at the right hand of the Father in heaven and make His way back to this earth. In one of those times, Jesus could return! That is an awesome thought. Someone has said that the average person blinks somewhere between 10,000 to 20,000 times a day. In the Twinkling of an Eye: "Behold, I show you a mystery We shall not all sleep, but we shall all be changed, In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed." I Corinthians 15:51-52. ![]() If challenging turn-based RPGs are your cup of coffee, if you liked old Ultimas, or Baldur's Gate games, or Planescape: the Torment on PC - then look no further, this is currently (June 2011) the best offering of this kind for iOS. Here, the storyline allows for you to join either of the two sides vying for power in Avadon, and thus for two endings which are very much the opposites of each other. A nice change from a pseudo-teenage protagonist saving the world from an ancient evil. As the storyline unfolds, it develops into a rich tapestry of political intrigue, courtly back-stabbing, power struggles, espionage and murder most foul. A cherry on the top of the icing is that the writing is well done and literary. The result is a game which quickly draws you in through nice graphics and an appealing storyline, and then keeps you fascinated with its complex game mechanics, skill tree progressions, challenging and strategical turn-based combat and a multitude of storyline choices and sub-quests. With Avadon he managed also a trick which many had failed at - to make the game instantly accessible without compromising any of its complexity. Jeff Vogel, the man responsible for this game, has spent over a decade now crafting well thought-out, complex, turn-based RPGs for PCs and Macs, aiming at the enthusiasts of the genre. "Anybody who pines for the days of the older, massive classics and decries the state of the new streamlined, big-budget RPGs needs to put their money where their mouth is and buy this game. ![]() "Avadon: The Black Fortress is easily one of the best RPGs you can buy.

![]() Web applications typically consist of both PHP and JavaScript code: PHP code runs on the server side, while JavaScript runs in the browser. To have PhpStorm inform you every time it receives a request to a script to be skipped, select the Notify about skipped paths checkbox.Debug PHP and JavaScript code at the same time The script will be now executed upon receiving requests to it. To remove an entry from the list, select it and click or press Alt+Delete. Then click and in the dialog that opens choose the file or folder to skip connections to. To add a new entry to the list, click the or press Alt+Insert. On the Skipped Paths page that opens, configure an "ignore list" of scripts and folders with scripts not to be invoked if PhpStorm receives incoming connections to them. In the Settings/Preferences dialog ( Ctrl+Alt+S), go to PHP | Debug | Skipped Paths. ![]() To ignore a script when stepping through the program during a debugging session, configure a stepping filter. If a script is added to Skipped paths, it is only skipped when starting a debugging session for it. To have incoming connections to this script ignored, add the menu-ajax-script.php script to the skipped paths list. However, this script is still requested during the debugging session. This script works properly so you do not need to debug it. Suppose you have a menu-ajax-script.php that "reloads" a part of your web page. This approach can be useful, when your application contains scripts that use AJAX. ![]() You can also specify the scripts requests to which you want PhpStorm to ignore during debugging. To have the program run automatically up to the next breakpoint, resume the session by choosing Run | Debugging Actions | Resume Program or pressing F9. For more details, see Step through the program. ![]() To control the program execution manually, step through the code using the commands under the Run menu or toolbar buttons: Step Into F7, Step Out Shift+F8, Step Over F8, and others. You can now investigate the application.Ĭontinue running the program and examine its frames as soon as it is suspended again. If you have a deployment configuration defined, PhpStorm will offer to configure the mappings based on the paths you've already set in that configuration.Īfter reaching the breakpoint, the debugger is suspended. In the Incoming Connection From dialog, select the path mappings so that PhpStorm can map the remote files on the web server to the local files in your project. Reload the page in the browser and return to PhpStorm. If you are using a browser for which an extension is not available, you can generate the Start Debugger/ Stop Debugger bookmarklets and add them to your browser's toolbar.Īctivate the debugging extension in your browser:įor more details about setting the parameters manually, see Starting the Debugger for Xdebug and Zend Debugger GET Request Parameters for Zend Debugger. You can do it manually in the php.ini configuration file, or use one of the available browser debugging extensions. To enable starting and stopping the debugging engine from the browser, you need to set a special GET/ POST or COOKIE parameter. On the main menu, choose Run | Toggle Line Breakpoint.Īlternatively, select Run | Break at first line in PHP scripts to have the debugger stop as soon as connection with PhpStorm is established (instead of running automatically until the first breakpoint is reached). Set a breakpoint in your code by doing any of the following:Ĭlick the left gutter area at a line where you want to toggle a breakpoint. Debugging ports are set at the PhpStorm level on the PHP | Debug page of the Settings/Preferences dialog ( Ctrl+Alt+S).

By the way, instead of having to make a shortcut of the pinball. ![]() Zen Pinball HD is an excellent pinball game. This unique table features pinball bumpers and targets, plus a color monitor where you can take on a variety of old-school digital minigame challenges - an endless space scroller, plus car racing, missile defense, a block breaker, and more at incrementing skill. And with global highscores lists, you can challenge all your friends. Download Pinball HD Collection and enjoy it on your iPhone, iPad, and iPod touch. Then you'll find at your disposal everything from Star Wars Pinball to a handful of tables inspired by the Avengers, and of course original tables with no franchise relation.īut the best part of Zen Pinball HD is the complexity built into each and every one if its tables which, thanks to the huge quantity of secrets that they hide, will give you hours and hours of gameplay. Within the application you can get all kinds of tables, provided that you're willing to pay. ![]() Launch your pinball through various obstacles to earn points. It earned that spot not for the number of tables, which unfortunately stands at just one, but for the excellent physics at work behind the ball and the spectacular nature of many of the moves you can pull.

Zen Pinball HD is one of the best pinball games you can find for an Android device. ![]() But of course, Syncthing can sync between more than two computers at once, while the changes are happening. On the flipside, the fact that I run Unison once a week or so forces a kind of built-in review of the changes I made, so I can undo them if desired. And Syncthing definitely makes it easier to add more of my laptops and whatnot into the mix. In fact it can probably completely replace Unison for me, because I haven’t actually bothered replicating my stuff onto a separate physical HDD in years. The end.Īs for Syncthing, perhaps its most interesting property is that it can largely replace both Dropbox and Unison. All in all, Android is still awful and you should probably consider getting an Ubuntu Phone instead. The sync problem isn’t really solved yet, but it’s sure a lot better. It’ll be difficult to interact with the directory otherwise. Aard Dictionary doesn’t care where it’s located. Maybe a symlink? Oh drat, FAT32 strikes again. Syncthing-Fork for Android is a wrapper for Syncthing that provides an Android UI instead of Syncthings built-in Web UI. It’ll make some things a touch more complicated. Syncthing 608 Free Open Source Mac Windows Linux Android Android Tablet BSD Self-Hosted F-Droid Cloudron Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. On my phone, Syncthing can’t handle the MicroSD card, but we can trick it. Oh well, we’ll just sync within its own directory instead. ![]() Unfortunately Syncthing can’t sync wherever. In fact it’s where most of the best software is found. You can get by almost entirely on F-Droid alone. Or Google Play, if you don’t think it’s obnoxious. The main point is that this is all easier than running an FTP server on the device, plugging it in over USB, running a webserver on it to drop files into a browser window or whatever other overly complicated solutions might exist. The experience will not be anywhere near as good. There is a Syncthing client for Android, but there is no official client for iOS, only a third-party commercial option. Whilst Tailscale works on both iOS and Android, Syncthing has limited mobile support. But since in reality it’s almost exclusively a one-way street anyway, it doesn’t matter so much. Syncthing has a beta feature for untrusted device encryption that may add some protection. Syncthing isn’t ideal because of its lack of subdirectory selection. And if there is, it’d be a remote server under my own control. Running Unison in a chroot just doesn’t quite cut it… The obvious solution is something like Syncthing or Bittorrent Sync, which works regardless whether or not there’s a remote server involved. your files and sync them across all Similar to Syncthing and developed by BitTorrent, Resilio. Instead of a similar alternative, I’ve really always been irked by the lack of an easy to use Unison-like sync for my phone. How to fix the BlueMail Android app not receiving emails. Solutions like Dropsync are unfortunately super slow, probably because it seems to be mostly a clever hack that syncs files one by one. Perhaps I don’t want to put my whole Dropbox on my Android phone (although I’m not so sure I don’t), but obviously you should be able to select a whole directory to sync. ![]() For probably equally many years, they’ve had the most obnoxious Android app. According to the timestamp on Getting Started.pdf, I’ve been a happy Dropbox user since 2010. ![]() A raster image, as mentioned earlier, is resolution-dependent. Vector: ScalabilityĪnother key difference is in scalability. Vector art, on the other hand, is deeply rooted in mathematical equations or geometric shapes hence, its data is more about lines, points, and polygons. ![]() Raster images are made up of a finite number of pixels. One of the primary differences between the two formats is the structure. Now that you know the key features of each format, what are the key differences between bitmap and vector? Read on to find out. An example of a vector-based design is the business card you give your clients whenever an opportunity arises. This would be impossible with a rasterized format. For instance, depending on the use, a business logo needs to be resized now and then. This is because such projects are less detailed and are often subject to regular changes. Vector images are a more common sight in line-art applications such as logo designs. Other than, you also need not worry about extra space because even when enlarged, a vector-image uses relatively less space. It simply means that your image will retain its quality regardless of how you enlarge it. Nonetheless, worry not as this does not mean you'll be dealing with calculus during editing. That is why you'll sometimes hear someone refer to the lines, shapes, and curves of a vector-based graphic as vertices and paths. The resolution of vector images is often dictated by mathematical equations. Vector-based data is often made up of various lines, shapes, and curves. An excellent example of a raster image is that selfie you just snapped. When used in print such as magazines and books, they are often printed at a high PPI so the output can be of top-notch quality. Therefore, you'll find raster images across the internet and on digital publications. It puts the photographer or designer in control of the end-results as they can edit each of the pixels to achieve whatever effect they desire. Again, this is owing to their pixel-based structure. Rasterized graphics are a more popular choice in non-line art applications, such as digital photography. This explains why they are a preferred option when it comes to web applications. While on the one hand, it's a downside, on the other hand, the pixel-based structure of a rasterized image is also an advantage as it can be scaled down to fit applications that require small-detailed images. Thus, if space is an issue for you, it would be wise to downsize. You will, nonetheless, need a bigger disk as more pixels in an image mean that it'll use more disk space. Therefore, to ensure your raster-based images are of the best quality possible, use more pixels. Thus, the more pixels present per inch(PPI), the better the resolution and vice versa. The resolution of a raster image is however dictated by the number of pixels in every inch. When you zoom in or enlarge, you're practically forcing your device to create non-existent pixels, hence the pixelation. While raster graphics are popular, it's vital to note that due to their pixel-based structure, they tend to be grainy or blurry when resized or enlarged. Some of the most common raster formats include: In most cases, these pixels are square-shaped, regularly spaced, and each one carries a specific shade, which contributes to the vivid and detailed appearance of the image. Also known as a bitmap, a raster image is a graphic made up of thousands or even millions of colored dots known as pixels. If you use the internet every day, then you encounter raster graphics daily. raster image? Take a look at the breakdown of each below. Raster: What You Need to Knowīefore we get to the differences, what is a vector vs. Fortunately, you don't need to go anywhere, as described herein is all you may need to know about raster vs. It also makes it easy for you to explain to a client why it's not possible to enlarge their regular family photograph into a ten-foot canvas. Having a clear understanding of the perks of each format makes choosing the perfect one for your project seamless. While at it, also ensure you get a high-quality video converter like the one from Movavi for more straightforward file conversion. Instead, take time to fully understand what each file format brings to the table. So if you're a newbie to the mentioned fields and find yourself in such a tight-spot, fret not. Raster or vector? This is a dilemma that even the most experienced photographers, graphic designers, or webmasters face every once in a while. ![]() It requires consideration of the way we structure our time. ![]() From Graham’s distinction between makers and managers, we can learn that doing creative work or overseeing other people does not necessitate certain habits or routines. ![]() Paul Graham of Y Combinator first described this concept in a 2009 essay. The two wildly different workdays of Murakami and Vaynerchuk illustrate the concept of maker and manager schedules. What we can learn from reading about the schedules of people we admire is not what time to set our alarms or how many cups of coffee to drink, but that different types of work require different types of schedules. Getting up at 4 am does not make someone an acclaimed novelist, any more than splitting the day into 15-minute segments makes someone an influential entrepreneur. The numerous articles we have all read about the schedules and routines of successful people like these often miss the point. It is a scaffolding on which a worker can stand and labor with both hands at sections of time.” - Annie Dillard, The Writing Life What we do with this hour, and that one, is what we are doing. “How we spend our days is, of course, how we spend our lives. In short, his day, for the most part, involves managing, organizing, and instructing other people, making decisions, planning, and advising. During the moments between meetings and calls, he posts on just about every social network in existence and records short segments of video or speech. He describes his day (which begins at 6 am) as being broken into tiny slots, mostly comprising meetings, which can be as short as three minutes. In contrast, consider the schedule of an entrepreneur, speaker, and writer Gary Vaynerchuk. Murakami is known for his strict adherence to this schedule. Once the writing is done, he spends his afternoons running or swimming, and his evenings, reading or listening to music before a 9 pm bedtime. When he’s working on a novel, he starts his days at 4 am and writes for five or six continuous hours. Consider the daily schedule of famed novelist Haruki Murakami. ![]() Charging infrastructure already required under regulation, building codes, or.Taxes paid on charging station, labour, etc.Monthly or annual subscription fees associated with the charging station.Installation of non-EV charging infrastructure.Ineligible Costs include, but are not limited to: Parking and electrical design required by the charging stations and conduit.Site assessments including analysis of electrical capacity, review of panel capacity and infrastructure, and identification of design options.Labour and construction costs for installation of the charging station and associated conduit.Business license, strata status or non-profit status.To apply for pre-approval, the applicant must provide: The following documentation must be provided at the time of application: This incentive is intended for retrofit solutions only, new builds are ineligible and Be a single-family, duplex, or townhouse with private garages.To be considered eligible under this Program, a home must: Owners of multiple properties may apply but will need to show proof of title. Last year, Purdue engineers announced "an alternative cooling method" by inventing "a new, patent-pending charging station cable that would fully recharge certain electric vehicles in under five minutes – about the same amount of time it takes to fill up a gas tank.The incentive is open to B.C. EV cable charging research has been ongoing The "subcooled flow boiling," can cool cables carrying high charges, possibly allowing for a faster flow of electricity without risking components overheating, NASA's blog said. It could also fuel "vapor compression heat pumps to support Lunar and Martian habitats and systems to provide thermal control and advanced life support onboard spacecraft," the agency said. NASA said the technology that could charge EVs faster was developed to bring "nuclear fission power systems for missions to the moon, Mars and beyond." The agency said worldwide sales of EVs doubled in 2021 to represent nearly 9% of the car market and expects record sales this year "lifting them to 13% of total light-duty vehicle sales globally." The news from NASA comes as electric vehicle sales are on track to hit an all-time high this year, according to the International Energy Agency's recently released Tracking Clean Energy Progress update. "This same technology may make owning an electric-powered car here on Earth easier and more feasible," the blog said. "Application of this new technology resulted in (an) unprecedented reduction of the time required to charge a vehicle and may remove one of the key barriers to worldwide adoption of electric vehicles." EV sales expected to hit 'all-time high' in 2022 Usually, it takes EVs about 20 minutes to charge at a roadway station to possibly several hours using an at-home charging station, NASA and Purdue researchers say. What does that mean? NASA and Purdue researchers may have solved a longstanding question for those who want an EV, yet have concerns about how long it may take to charge it. Standard EV chargers that consumers can buy tend to provide less than 150 amps, the blog added. Using a technique known as "subcooled flow boiling," the tech could boost the amount of electrical current EV chargers by roughly 1,400 amps, nearly five times the rate of up to 520 amps currently supplied to EVs, NASA said. The federal space agency-funded technology, in partnership with Purdue University, says the research they're planning for future space missions shows its tech could charge an electric car within minutes instead of hours, according to an Oct. Purdue has been researching a cable that would fully recharge certain EVs in minutes for many years.Įxperimental technology used to cool equipment in space might soon be able to cut the charging times of electric vehicles to five minutes or less, NASA said this week.NASA and Purdue University researchers believe that electric cars be charged in five minutes.A cooling system to be used for future NASA space missions might be used to help charge electric cars. |
