Powerful prescription drugs are available that can eliminate super lice with one dose. Over the years, some lice (called “super lice”) evolved so that the over-the-counter treatments don’t effectively kill the lice. The treatment is only successful if you follow the instructions on how to apply the treatment, how long you should leave it in your hair and how often you should repeat the treatment. Make sure you follow the directions on over-the-counter medicines. After using a comb or brush, soak the comb in hot water for 10 minutes. Lice and nits attach to the strands of your hair and can be hard to remove unless you use a fine-toothed comb to loosen them. Over-the-counter medicated shampoos contain a substance called pyrethrin or permethrin that kill lice and nits. Treatment for head lice includes using over-the-counter medicated or prescription shampoos, lotions or creams that eliminate head lice. Although rare, head lice can spread through personal items like towels, sheets, hairbrushes or hats.Īnimals and pets can’t get or spread head lice to humans.

Additionally, you can assign a start/stop key, suitable for enabling or disabling the automatic clicking process. RapidClick brings a large number of mouse clicking rates that will satisfy most users, ranging from 20 clicks per second to a single click per hours, this will suit the needs of anyone that uses it. Built-in support for both left and right click automationĪnother unique feature is the fact that it also makes it possible to add automatic clicking capabilities to both left and right click, a feature that distinguishes it from similar applications that mostly provide auto-clicking for a single button. On top of that, it brings visual and audio feedback in order to notify you about each click, so it certainly won't go unnoticed. RapidClick can be used in different situations, like those times when you are away from your desktop, and you want to keep the screensaver from appearing. For intervals of more than 1 second, the time is now displayed as minutes:seconds and there is a countdown to the next click.Increased the maximum click rate from 20 to 50 clicks per second 1 (something highly requested in emails and App Store reviews).Universal app for both Intel and Apple Silicon (of course).Click automation at its best for both advanced and beginner Mac usersįurthermore, it can also be useful when playing games that need a large number of clicks per second and others might use it to perform tedious everyday tasks that require a large amount of clicks in a short period of time.īottom line, RapidClick is a quite easy to use and configure tool that you'll certainly need when you have to click multiple times per second or when you need to periodically click an activity tracker.Yesterday I released an update (v1.5) to RapidClick, my auto clicker app. RapidClick now shows a countdown to the next click. The update was long overdue, also fixing a long standing problem where RapidClick would crash if the user denied the system Accessibility permission prompt. Now there is a proper welcome UI flow to guide the user to enable the permission. Every developer loves the Secutiry & Privacy preferences pane. This permission prompt is the kind of UI flow that is really fiddly to make, and yet the user sees it only once in the lifetime of the app. If it is implemented well, they probably never really notice it it all. I did it here with this kind of bubble thing. It’s also now RapidClick’s 10 year anniversary. I don’t talk about RapidClick very much – it is a very simple app and it’s not especially interesting to most people. And yet, it was a very important step in my Mac development “career”. ![]() ![]() ![]() It was the second app I ever published – a few months before PopClip.Īt that time I had already released DwellClick (both 1.0 and 2.0), which I had spent more than a year of my life working on. It sold very few copies and I was close to giving up. It was RapidClick that actually broke through and sold enough to make me think there might be some possibility in this whole app development thing. RapidClick first appeared on the Mac App Store on 25th March 2011. It started as an offshoot from DwellClick, my assistive app for using a Mac without pressing a mouse button.

5/2/2023 0 Comments Pinkerton detective agency![]() ![]() But after tracking them to James' mother's farm in Missouri, the resulting standoff ended in tragedy. In 1875, Pinkerton decided to go after Jesse James and his gang. The Reno Gang were some of the first train robbers in the United States and in the late 1860s Allan Pinkerton chased down Frank Reno himself. As a result, they were denied a Christian burial. And according to Famous Trials, the trials against the Molly Maguires "fueled discrimination against Irish Americans and suspicion of the trade union movement, both of which lingered for decades."Īccording to Smithsonian Magazine, after the Civil War, the Pinkerton agency worked on a number of high-profile train and bank robberies and recovered hundreds of thousands of dollars. Public opinion was also heavily swayed against the Molly Maguires, and before their death, the condemned men were excommunicated by Philadelphia Bishop James Frederick Woods. ![]() However, despite the strike ending, the men were still forced by the mine owners to stand trial between 1875 to 1877 in order to "uncover alleged crimes committed by the Molly Maguires."ĭespite the fact that there was no evidence linking the men to the Molly Maguires and the trials provided no evidence that such a secret society even existed in the United States, 20 men were still sentenced to death by hanging. With his help, police arrested 60 miners under the accusation that they were part of the Molly Maguires and with the arrests the strike was defeated. Pinkerton also reportedly physically restrained two journalists in order to keep them from reporting their plan.Īccording to the Pennsylvania Center for the Book, a Pinkerton detective named James McParland, a native Irishman, claimed to have infiltrated the Molly Maguires. Pinkerton and his agents discovered that "conspirators, in league with members of the Baltimore police force, planned to assassinate Lincoln as he rode in an open carriage." But by arranging for the Harrisburg telegraph lines to be cut, Pinkerton was able to ensure that few heard of Lincoln's sudden departure from Pennsylvania back to Washington, D.C. Instead, he suggests that Scobell was a fictional character invented by Allan Pinkerton.Īlthough Pinkerton was known to exaggerate his exploits, he was in fact responsible for foiling an assassination attempt on Lincoln's life right before his first inauguration in 1861. However, in " The Myth of Ex-Slave Turned Civil War Spy John Scobell," Corey Recko claims there's little-to-no proof that Scobell ever existed. According to the Pinkerton website, one of the men recruited as a Union Intelligence officer was John Scobell, the first Black Union Intelligence officer who had been formerly enslaved in Mississippi. ![]() ![]() You might have to fiddle with your DirectX settings to get it working right.

Most Piano Companies now have the option to buy the Piano you are renting with some of the rental payments going towards the final purchase of the instrument, this will vary from company to company and would advise you to shop around for the most comprehensive and competitively priced company. Maybe a company that allows you to 'try before you buy' in the form of rental may be the ideal solution. Your piano tuner will be able to advise you on this.ĭon't feel confident in choosing the right instrument? If you feel that your piano is in an unsuitable environment you should think about purchasing either a humidifier to counteract excess dryness or a dehumidifier for excess dampness. Ideally, you should try to keep your piano within 45 - 60 per cent relative humidity. Changes to humidity in a room where the piano is stored are often responsible for tuning instability and other serious problems, such as loose tuning pins, split soundboard's and regulation issues. These changes in relative humidity causes the wood in the piano to shrink and expand. When the heating is turned off at night the humidity in the room rises, then when turned on in the morning, the humidity drops. Central heating dry's the air, drawing moisture from the wooden components in the piano. A constant temperature around 18☌ to 21☌ (65☏ to 70☏) is ideal. avoid draughts if possible, keep away from windows, radiators & other sources of heat. The environment will affect a pianos tuning, so avoid placing them where this may be an issue i.e. Where is the best place for my piano? A piano doesn't like being too cold or too hot.

A concert pianist’s piano would usually require an annual service whereas a beginners may only need to be looked at every five or so years to maintain its optimum playing condition. All pianos need to be serviced at some time in their life, this will depend on the amount of usage they receive and the conditions in which they are kept. ![]() The pitch will drop if the piano is not tuned on a regular basis and the environment can often determine how many times it needs to be tuned. New pianos and older instruments may require tuning more often. How often should your piano be tuned or serviced? It is recommended to have your piano tuned a minimum of once a year, but most pianos if played regularly should be tuned twice a year. ![]() ![]() ![]() Temps is an electron app with a beautiful UI (though not exactly “light”).

It’s a distinct feature that I haven’t encountered in any other weather app. Most of that weight comes from the great Maps features, with maps presenting temperatures, clouds, precipitations, pressure and wind speed. Integrated into System Tray (Top Panel).If you prefer, you can get a flatpak version. After logging out (and logging back in), the Calendar extension will be displayed.

Can save multiple locations (that can easily be changed).I hoped that it’d infer the encryption methods by some protocol magic if the fields were empty, but that wasn’t the case.These applications usually sit on the top panel of your screen. The key was that I had to set the Phase 1 and 2 encryption methods (which were empty by default) in the IPSec Settings panel of the VPN’s settings. The config manuals for Mac I was given didn’t have any other steps so I was kinda running out of ideas. I added the VPN, set the server’s IP and my credentials. It added the Layer 2 Tunneling Protocol option to the network settings all right. However, I went another route (that I found before I saw that answer about StrongSwan), using network-manager-l2tp (which was deprecated for its dependency on OpenSwan, but is still in universe) and network-manager-l2tp-gnome (as pointed out in a comment). (However, I tried it on 18.04 and I was unable to add a VPN as the Save/Apply button simply wouldn’t work.) Luckily it’s in the main repository, so it can be installed without much hassle. Apparently L2TP was removed at 16.04 for some dependency reason, and replaced with a package called StrongSwan. Since everyone uses Macs or Windows at the office there are no manuals or guides to set it up on linux, so I had to figure stuff out myself.įirst of all, Ubuntu doesn’t have L2TP support out of the box currently, but luckily Ask Ubuntu has plenty of questions on the topic. Occasionally I work from home, and access to certain development resources is restricted to either the office IP or the use of a secure VPN. It may not be up-to-date or reflect my current ideas or best practices. ![]() 5/1/2023 0 Comments Maptiler map pin![]() ![]() ![]() You can read about the difference between vector and raster tiles here Customize the look&feel of the base maps quickly Vector tiles support requires QGIS 3.13 or higher.įor the plugin version 2.0 and higher, you need QGIS 3.16 or higher.įor the plugin version 3.0 and higher, you need QGIS 3.24 or higher.

Basic calculators usually store only one number at a time more specific types are able to store many numbers represented in variables. Also, some fractions (such as 1⁄ 7, which is 0.14285714285714 to 14 significant figures) can be difficult to recognize in decimal form as a result, many scientific calculators are able to work in vulgar fractions or mixed numbers.Ĭalculators also have the ability to save numbers into computer memory. Fractions such as 1⁄ 3 are displayed as decimal approximations, for example rounded to 0.33333333. Various symbols for function commands may also be shown on the display. Large-sized figures are often used to improve readability while using decimal separator (usually a point rather than a comma) instead of or in addition to vulgar fractions. Most basic calculators assign only one digit or operation on each button however, in more specific calculators, a button can perform multi-function working with key combinations.Ĭalculators usually have liquid-crystal displays (LCD) as output in place of historical light-emitting diode (LED) displays and vacuum fluorescent displays (VFD) details are provided in the section Technical improvements. Scientific calculator displays of fractions and decimal equivalents InputĮlectronic calculators contain a keyboard with buttons for digits and arithmetical operations some even contain "00" and "000" buttons to make larger or smaller numbers easier to enter. By 2007, this had diminished to less than 0.05%. In 1986, calculators still represented an estimated 41% of the world's general-purpose hardware capacity to compute information. With the very wide availability of smartphones and the like, dedicated hardware calculators, while still widely used, are less common than they once were. As of 2016, basic calculators cost little, but scientific and graphing models tend to cost more. Graphing calculators can be used to graph functions defined on the real line, or higher-dimensional Euclidean space. Some calculators even have the ability to do computer algebra. For example, there are scientific calculators which include trigonometric and statistical calculations. In addition to general purpose calculators, there are those designed for specific markets. Calculator functions are included in most smartphones, tablets and personal digital assistant (PDA) type devices. By the end of that decade, prices had dropped to the point where a basic calculator was affordable to most and they became common in schools.Ĭomputer operating systems as far back as early Unix have included interactive calculator programs such as dc and hoc, and interactive BASIC could be used to do calculations on most 1970s and 1980s home computers. ![]() They became popular in the mid-1970s as the incorporation of integrated circuits reduced their size and cost. Modern electronic calculators vary from cheap, give-away, credit-card-sized models to sturdy desktop models with built-in printers. Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel for the Japanese calculator company Busicom. The first solid-state electronic calculator was created in the early 1960s. A modern scientific calculator with a LCDĪn electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. ![]() |
