Overall wget is one of the most useful commands around, and hopefully after reading this you’ll download it and get used to using it (if you weren’t already). You can mirror a website using wget easily. They wanted to backup some really old WordPress sites and just archive them as simple html files. While I was crossing the Williamsburg Bridge in NYC I received a Slack chat from a customer. I also frequently need to use the -r operator, which allows for recursive downloads and the -o operator which outputs to a log file. The command is simple and to mirror a website using wget works fantastic. There are a lot of options for wget, but some that I use more than others include –user= and –password=, which allows you to authenticate to a host by specifying a username and a password (respectively of course) and –limit-rate, which funny enough, let’s you throttle the speeds of transfers so as not to saturate your bandwidth. To use it, simply use wget, followed by the path to the file you’d like to download using the –tries option: You will then have the wget command located in /usr/local/bin/wget. Then run the installer (with elevated privileges: You will then have a directory called wget- followed by the version of wget you just downloaded (currently 1.12). Next, extract the tar file using the tar command: To do so, either download it manually from or use the ftp command to do so for you: For example: In the above example, -r and -l1 options together enable 1-level deep recursive retrieval, and -A option specifies lists of file name suffixes to accept during recursive download (. Once the developer tools have been installed, you’ll want to download the latest version of wget from gnu. In this case, you can use the -r option of wget to download multiple files in the directory. To get started, install the developer tools for Mac OS X so that you can get a working copy of a compiler (gcc). Therefore, let’s look at installing wget. But while it comes included with most distributions of Linux, it is not built into Mac OS X by default. On top of that, there are so many free software commands out there that you might as well give them a try and see what you've been missing.ĭo you know any commands that might be good for us to know? Let us know your thoughts in the comments.The wget command is used to download files from the web and is one of the most useful commands around. The flexibility of the command line trumps GUIs in some cases. I can create a script to run a command depending on various triggers. I can schedule a command to run at a later time. I can quickly run a command in the terminal without the need for a large graphical program to start. The answer is simplicity and convenience. Some of you may be wondering on why I bother with command line programs when a I can likely find a nice GUI program that does the same thing. You can check out our article on installing Brew for more information. You can download and compile wget from the FOSS maintainers directly or you can install the Brew package manager and simply use the brew install wget command in the terminal to have it done automatically for you. You can then scroll through the document as needed to find help on any option available. ![]() ![]() You can access this manual from the terminal by typing man wget and pressing enter. ![]() Luckily, installing wget via the Brew package manger (explained briefly below) will also install the wget instruction manual. Need to use a personal login for getting access to specific directories? There's another option for that. Need to archive only the documents on the first two pages of a website? There's an option for that. Since web protocols can be complicated, wget has a myriad of options to deal with that complexity. Wget can be instructed to convert the links in downloaded files to point at the local files, for offline viewing. This is sometimes referred to as "recursive downloading." While doing that, Wget respects the Robot Exclusion Standard (/robots.txt). The process is straightforward and automated. The installer will give you live progress updates, and there’s little you need to do here. From the Terminal again, run: brew install wget. Next up, we want to use Homebrew to install wget. Wget can follow links in HTML, XHTML, and CSS pages, to create local versions of remote web sites, fully recreating the directory structure of the original site. After you confirm, the installer will run. wget is a very handy Unix command line utility to download files over http. It's designated as a "non-interactive" command because you can initiate the program and leave it to do its work without any other user interaction. The wget command is network downloader that can follow and archive HTTP, HTTPS, and FTP protocols. ![]() Don't hesitate to get one and have a badass beard!

Sure, there's some sawing at the wheel from test driver Marc Lieb (one of three testers, including legendary rally king Walter Röhrl), but he makes wrangling the Martini-liveried 918 look kind of easy. Perhaps what's remarkable is just how undramatic it all looks. The video, which runs about eight-and-a-half minutes, and shows the 918 from inside the car on a flying lap of the German track. Porsche has released on-board footage of the 6:57 lap. Well, after an official press release, which we ran earlier today, we have your "pics." Moving pics, to be more exact. "Pics or it didn't happen!" You could almost hear the Internet shouting this when news started to trickle in about a sub-seven-minute Nürburgring lap by the new Porsche 918 Spyder. Watch onboard video of the Porsche 918 Spyder's record 'Ring lap Tue, Whether sister brands like Volkswagen, Bentley or Lamborghini will get their hands on it remains to be seen. But nowhere else: despite the apparent leak, the patent drawings suggest that Porsche will be keeping this technology proprietary. No word on when it might hit the market, but we won't be surprised to see this kind of device appear on a future version of the Boxster or 911 Cabriolet. The mechanism is apparently fitted to the headrest itself and designed to keep the wind buffeting specifically around the head down to a minimum while allowing the car's occupants to enjoy the top-down driving experience. These patent drawings have leaked out, demonstrating what appears to be some new kind of wind-deflecting device being developed by Porsche. But Porsche is apparently preparing to kick it up to the next level. That's why you see so many convertibles driving with their tops up, their windows up or wind deflectors in place. While driving around in a convertible might seem glamorous, ask anyone with long hair and they'll likely tell you how it really is: the wind buffets, your hair goes everywhere and it's anything but glamorous. Porsche patent sketches show removable headrest wind deflector Mon, In case of doubt, it is always advisable to ask the vehicle manufacturer whether the replacement is worthwhile and does not lead to any technical problems. Therefore, the corresponding references are to be seen as an option, a suggestion. However, in practice it can occasionally happen that the desired improvements do not occur in operation. For almost every NGK standard spark plug there are corresponding NGK Iridium IX spark plugs, which technically bring the advantages mentioned above.A total of 5 kOhm interference suppression per cylinder is sufficient, more than 10 kOhm can reduce the ignition energy of the spark. all spark plugs marked with an "R" have an integrated 5 kOhm suppression resistor, which is only necessary if 5 kOhm suppression plugs are not already used.Failure to do so may result in serious damage to your vehicle for which we disclaim all liability and warranty in advance. Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior. Only use products and specifications that have been approved for your vehicle. If your owner's manual is not available, contact your workshop or the motorbike manufacturer. If you cannot find the right spark plug for your vehicle at first go to "My Bike" or have a look at the "Cross Reference List", which can be found under documents.īefore (!) buying and before (!) fitting spark plugs, you must always make sure that the spark plugs you have chosen correspond exactly to the specifications and approvals in the manufacturer's owner's manual for your vehicle. considerably longer service life compared to standard spark plugs.counteract fouling in stop-and-go traffic.better acceleration due to more spontaneous throttle response.In addition, the service life of NGK Iridium IX spark plugs is at least twice as long as that of standard spark plugs. These spark plugs offer excellent starting behaviour, better acceleration through more spontaneous throttle response, they reduce fuel consumption, counteract sooting in stop-and-go traffic. Iridium IX spark plugs from NGK go one better by ensuring optimum ignition and smooth engine running. This is one of the chief differences between Iridium vs Platinum spark plug. Platinum-made spark plugs go a little longer than copper plugs but do not touch 25,000 miles. These spark plugs are well known for accomplishing the 50,000 miles mark without any issues. Because as inconspicuous as a spark plug may be, its effect on fuel consumption, willingness to start and the engine's enjoyment of performance is huge. Iridium spark plugs offer the longest lifespan to your vehicle. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.Choose Iridium spark plugs from NGK in guaranteed top quality. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Keeping this in view, do iridium spark plugs make a difference? If it's tuned for the iridium, use the iridium. I would bet the engine is turbocharged, which is probably why they went iridium in the first place. The extra money you put into the tougher plugs which are called for, will last longer saving you money in the long run. Also Know, can I use regular spark plugs instead of iridium?Īgreed. This makes ignitions faster and more reliable, and also reduces power consumption. Iridium spark plugs are better at starting engines than other types of spark plug because the spark is highly concentrated in the central electrode, and consequentially requires less voltage to operate. Furthermore, is it worth buying iridium spark plugs? However, you can use platinum if it happens to be the spark plug your budget can afford. Iridium spark plugs offer better performance compared to platinum, but they are usually costlier than platinum. Can I replace iridium spark plugs with platinum?

![]() We have some bad news and some good news. There is a lot more about the game to share, but for now please enjoy this first tease of the game and one of the key gameplay possibilities that Earthlock 2 will explore Earthlock 2 will be an open-world action RPG with complex interlocking systems that work together to offer players extensive freedom to customise their own experience. The original Earthlock was a very classic turn-based late 90s JRPG-style experience, but with the success of the first game giving the team ample opportunity to grow, Earthlock 2 will take the franchise to the next level. The game’s story centres around a group of friends who must set out to find and rescue their missing family members. Along the border in the middle, there is an area that gets the best of both worlds. I didn't realize at all that I can remap the combat options.The Earthlock series is set on the planet of Umbra, which has stopped spinning on its axis, meaning half of the world is completely shrouded in darkness, while the other half is constantly baked in sunlight. I actually found out how to use Fire ++ ammo only when I got the last plant. I mean, why would I want to shoot at something with Fire if I have Fire ++? Upgrades could just replace "old ammunition". Maybe simplify ranged combat: Why are there different level of ammo available. But let me see at once that I travel to "sublocation X". Color them, make dots there for the sublocations, I don't know. Different icons per location: When teleporting to Suvia I can't count how often I landed up in that warehouse. Direct teleportation: I know, it somewhat makes sense storywise to always teleport to the homebase, but it would be nice to be able to skip that. Sure, it totally makes sense that only Gnart can harvest herbs and only Amon can scavenge scrap piles. Overland skills: It is really annoying to switch between overland skills. Scouting isn't an option, because it is too slow. Fights for no xp and without any challenge at all are pretty annoying. Overland travel: Later on those pesky low level critters become really annoying. The addition of fetch quests was welcome from the original, but there could always be more involved ones. Accessories in the next game which can let you block some status effects are a MUST-HAVE.ģ) More involved sidequests. That was absolutely not fun in the slightest. Spoilers, NEVER do that, you will effectively never get a turn, ever. Trails in the Sky has a system like that.ĮDIT: I just tried to fight 6 ghosts at once. Cure only works on one person and only on DoT effects, and the enemies tend to spam those on you, so Cure ends up being pretty useless a lot of the time.Īccessories could be more things found in buried loot, treasure chests, and shops (and act as a minor money sink of sorts). Right now there are a bunch of status effects which are nasty and yet there aren't really any tools for dealing with them. Such info would also be welcome in this game too.Ģ) Add 1-2 accessory slots, and accessories which you can equip to render your character immune to specific status effects. You could need to kill some number of them (like 10-15 for normal enemies, 1 for bosses), or the information could only appear once the specific item drops or is stolen once. You don't need to give that information all at once. What would you like to see in Earthlock 2?Īnd please keep the reviews and feedback coming!ġ) The Bestiary should list the Drops and Steals that each monster has. Such feedback is important for the bug-fixing we will continue to do on Earthlock 1, but it is also valuable input into the process of making the next game! So who should we begin inviting as we build this community? We feel it seems natural to invite anyone who took the time to write a review, give us feedback or report bugs. With the community involved early we think we can make an even better game this time around.Īs soon as we have something to share and talk about for Earthlock 2 we will engage with our community and involve them as much as possible. This is something we were not able to do with the first game. In a few months we will set up a new community for Earthlock 2. The great thing about making game number two is that we now have a wonderful community of players along with us. We are super excited and look forward to sharing it with you. It is a very exciting phase to go into early production of a game. ![]() I would be glad if Norton could figure out a way to only scan the applications when there have been some changes in the basic utility of application or if they are being started after restarting the system.įor a bit more calculated results to rely on, let’s look at the results gathered by AV-Test Lab. The thing I didn’t like was the application lag was there every time I opened the application even in the same session. In my testing, I noticed a considerable amount of lag in opening and running applications. In my 10-days of usage on my laptop equipped with 9 th Gen i5 processor, it definitely showed its impact (So did its competitors). Not all systems are equipped enough to handle the changes and even if they are, it is worth calculating their impact on the performance. They tend to check every file every time they are opened, run a security check in the background on every application you choose to work with which shows its impact on the system performance. Effect on System Performance:Īntivirus solutions, especially for the PC, are a bit heavy on the system. With the results given above, we can surely conclude that though Norton secures us with almost 100% malware attacks, it can’t be the reason to buy Norton over others. Therefore, here are the results of a couple of other antiviruses available in the market. But these results don’t help us compare its performance with other antiviruses. Norton was able to score 6 out of 6 in the ratings provided by AV-Test Lab. In an evaluation conducted in July 2020 Norton was able to detect and eliminate 100% of all the 14,000 malware samples it was tested against. In addition to that, there are many third-party independent labs that test the performance of security solutions including antiviruses and rate the product according to their rating formula. (So, did most of the other antiviruses in the market like Bitdefender and McAfee) With all the 7 test websites I tested it against, it worked fine. In my 10 days of usage, I tested Norton 360 Deluxe with all the test malware sites and Norton didn’t disappoint me.

We suggest that pleural fluid serum amylase levels be measured only if there is a pretest suspicion of acute pancreatitis, chronic pancreatic disease, or esophageal rupture. Amylase levels greater than 100 U/L (normal serum level in our laboratory is 30-110 U/L) were found in 5 (1.3%) of 379 patients: 1 patient with congestive heart failure (amylase, 173 U/L), 2 with post–cardiac surgery effusions (144 U/L and 130 U/L), 1 with pneumonia (109 U/L), and 1 with lung cancer (105 U/L).Ĭonclusions The routine measurement of pleural fluid amylase levels is neither clinically indicated nor cost-effective.
