The good news is that tcsh autocompletes your files, and quotes them according to the correct archanesyntax. The command above says to search recursively starting in current directory ignoring case on the pattern and to only search in files that match the glob pattern '.cpp'. Many a program failed utterly when a text field had a quote mark or a leading pace, etc. If you are using GNU grep, then you can use the following: grep -ir -include '.cpp' 'xyz'. I even have a database test item in all databases I made, called the "O'Reilly" test. Nowadays, we need to support all file names, even "O'Reilly's Army.txt". Also, it's an old habit from the days when you only got 8 chars to say it. Most techies I've worked with use the 3-fingers-on-one-hand-2-on-the-other method, and they like to use short variable name, don't like to comment, and in general cannot be counted on to help with the user doc. Maybe because, unlike most programmers, I can type with ten figures at a normal writing speed - few people need more than 40 words per minute to type as fast as they can compose. I'm a big fan of English language file names, that is, not something like RSFunc97Stat.txt. It doesn't crap out as soon as it hits the space. Now if your file name is /home/he/Documents/00 - Writing/02 The Rapture of the Maiden/0 - Text/25th/Rapture, pt 1-4, ch 01-20 old.txt, Beneath the current directory on this test machine, there are nested directories containing logfiles, CSV files, and MD. There may well be multiple types of files we wish to exclude. By default, it will search through all files in those locations. I use the C-shell, as I was a berkeley/Sun user at the Lab, but the same ideas apply in bash. When we use the -R (dereference-recursive) option grep will search entire directory trees for us. To get it to work on anyįile system, EG NTFS, you need to quote the $PWD. Garbage if you have actual file names, not Unix-style file The problem is $PWD, which results in useless Is there a faster way to do what I am trying to do than to use find? However, it is a ton to type, and it is certainly not as fast as using ls with grep. This will give me a nice format (It also includes the user, group, size, and last date of access, which are helpful). If I just use find without ls or grep, then it goes faster, but it is a bunch to type: find $PWD/ -type f -name file.name -printf '%M %u %g %s\t%a\t%p\r\n' I can use ls integrated with find and grep to get the output in exactly the format that I want, and I could use something like this: ls -ault `find $PWD/ -type f` | grep file.nameīut this is extremely slow, I'm guessing because two commands are actually running. I would prefer to use ls because it is the fastest, and I would type: ls -alR $PWD/īut this doesn't show the file's path, so if I grep'ed the output, then I would see file permissions, but not the directory from which it originated. I want to do this so that I can grep out what I want, so that when I run the command, I can get just the matching files, their permissions, and their full paths, like: | grep file.name He took the name from the ed command string g/re/p, which translates as "global regular expression search.I have done a bit of searching online, and I am trying to find a way to recursively list all files with their absolute path and with their permissions. Thompson spent about an hour that evening making his tool a general utility that could be used by others and renamed it as grep. He needed a tool that could search for phrases and strings within text files. McMahon was trying to identify the authors of the Federalist papers through textual analysis. His department head at Bell Labs, Doug Mcilroy, approached Thompson and described the problem one of his colleagues, Lee McMahon, was facing. Ken Thompson had extracted the regular expression search capabilities from the ed editor ( pronounced ee-dee) and created a little program - for his own use - to search through text files. The first two are bang on the third is slightly off. Thirdly, it was written overnight to satisfy a particular need. Secondly, the wealth of options can be overwhelming. The grep command is famous in Linux and Unix circles for three reasons. It also works with piped output from other commands. The Linux grep command is a string and pattern matching utility that displays matching lines from multiple files.

For learners who may wish to continue their studies in the future, associate degrees can help ease the transition. Prospective students may encounter several types of pharmacy technician training, including certificate, diploma, and associate degree programs.Ī pharmacy technician associate degree is typically the most involved of these options, featuring more general and medical foundation courses. Students can complete these programs in two years or less while developing pharmaceutical inventory, calculations, and communication skills. Online pharmacy technician associate programs attract students looking to build a medical foundation and enter the field in a relatively short period of time. What Can I Expect From an Online Pharmacy Technician Associate Program? It also highlights the best online pharmacy technician associate programs from the top online schools. To help prospective students decide if this field interests them, this guide explores the program in detail, along with opportunities after graduation. Bureau of Labor Statistics (BLS) projects the addition of more than 16,000 new pharmacy technicians between 20. Typically offered at community colleges, these programs usually require approximately 60 credits and can be completed in two years or less.Īs pharmacists take on more patient-care responsibilities and the population ages, pharmacy technician responsibilities will grow with these demands. A pharmacy technician associate degree offers the most direct route to this field, providing foundational training in pharmacology and terminology. Pharmacy technicians dispense medications, fill prescriptions, and assist pharmacists. The Public Ivies, Little Ivies, and Other Ivy League Equivalents. Therefore, doping atoms modify electronic properties as well as the ionic conductivity of ZnO. On the other hand, doping ZnO with transition metals and alkali metals can create p type conductivity. ZnO is a wide band gap semiconductor with naturally an n-type electronic carrier. Furthermore, for recent technological applications, the most important advantage of Li doped oxide semiconductors are being suitable electrolyte materials for low temperature solid oxide fuel cells 17, 18, 19, 20. As mentioned in literature, thermal stability, electrochemical stability and low leakage currents are the possible advantages of Li based solid oxide fuel cells 14. Among the dopant atoms, lithium (Li) is the most promising elements for SOFCs 16, 17. Furthermore, increased in dopant atom amount in oxide semiconductors modified the ionic conductivity, operating temperature, relaxation mechanism and cycle performance in a solid oxide fuel cell 14, 15. For example, ZnO based composite electrolytes such as ZnO-LCP (La/Pr doped CeO 2) and BaCo 0.4Fe 0.4Zr 0.1Y 0.1O 3-δ-ZnO with ionic conductivity values of 0.156 Scm −1 (at 550 oC) and 0.098 Scm −1 (at 500 ☌), respectively 11, 12, 13. The other studies also show that p-n heterojunction composite electrolytes create low-temperature operation of solid oxide fuel cells with good enough ionic conductivity values 11, 12, 13. The ionic conductivity performance of oxide semiconductors as an electrolyte material in a Na 2CO 3 (Sodium Carbonate) matrix is widely interested subject in SOFCs 10 to decrease the working temperature of fuel cells with high ionic conductivity performances. As well as boundary size, the boundary environments were also investigated subject 10, 11, 12, 13. The effects of grain boundary size change were also investigated for oxide semiconductors in previous study 9. Thus, high specific surface area and controllable surface defect amount enhance the usage ability of oxide semiconductors as a SOFC with high efficiency. Moreover, ionic conductivity mechanism through the grain-boundaries is the other investigated subject for SOFCs. In recent studies the polaron conduction is widely investigated subject such as chalcogenide glassy systems depend on partial amorphous phase ratio in a crystal structure, defect amount in lattice, defect type and dopant atoms 4, 5, 6.ĭesired ionic conductivity at operating temperature with low electronic conductivity are the most important property of electrochemical devices, especially for solid oxide fuel cells (SOFCs) 7, 8. In addition, specific surface area and surface defect amount of oxide semiconductors can be also tuned. Low electrical conductivities and stability on wide range of environmental conditions make oxide semiconductors be suitable for sense and adsorption of fuel gases 3. Especially, for solid oxide fuel cells (SOFCs) because of low electrical conductivities even for high temperatures (>300 oC) due to their wide band gaps. Low cost in production and suitable physical properties to wide variety of technological applications make ZnO as an important alternative candidate material for scientific researches. Furthermore, the activation energy change by Li dopant amount implied the tuneable ionic conduction mechanism.ĭiscovery of oxide semiconductors are sparked a new field of materials due to easy producibility, tuneable surface reactivities, electrophysical and easily coating on any surface 1, 2. However, this specific temperature was tuned to high temperature by Li doping amount in ZnO lattice. Ac conductivity responses of each sample were disappeared at a certain temperature due to becoming electronic conductive oxides. The complex measurements were performed in an intermediate temperature range from 100 ☌ to 400 ☌. Moreover, the variations in ionic conduction dependent on 5, 10 and 20 mol% Li doped ZnO were analysed via ac impedance spectroscopy. Then, Rietveld refinements were performed to investigate the replacement of Li atom amount in ZnO lattice. The structural characterizations were performed by x-ray powder diffractometer (XRD) and x-ray photoelectron spectroscopy (XPS). We focused on synthesis of Lithium (Li) doped Zn 1-xCo xO (x = 0.00, and 0.10) nanoparticles employing chemical synthesis technique with a reflux setup under constant Argon gas flow. The recent studies indicate that internal point defects in solid electrolytes modify the electronic and ionic conductivity and relaxation mechanism of solid oxide fuel cells.

For access to the more advanced features, see these M-files and the Spline Toolbox. spline uses them in a fairly simple fashion to perform cubic spline interpolation. These routines form a small suite of functions for working with piecewise polynomials. For the ' spline' method, interp1 calls a function spline that uses the M-files ppval, mkpp, and unmkpp. The ' nearest', ' linear' and ' cubic' methods have fairly straightforward implementations. Then the population in 1975, obtained by table lookup within the matrix tab, isĪlgorithm The interp1 command is a MATLAB M-file. If a portion of the census data is stored in a single 5-by-2 table, Sometimes it is more convenient to think of interpolation in table lookup terms where the data are stored in a single table. Now interpolate within the data at every year from 1900 to 2000, and plot the result. The expression interp1(t,p,1975) interpolates within the census data to estimate the population in 1975. P = Described in table lookup terms, the table is tab = and interp1 looks up the elements of xi in x, and, based upon their locations, returns values yi interpolated within the elements of y.Įxamples Here are two vectors representing the census years from 1900 to 1990 and the corresponding United States population in millions of people. Interpolation is the same operation as table lookup. This is shown below, along with the relationship between vectors x, Y, xi, and yi. It finds values of a one-dimensional function f(x) underlying the data at intermediate points. The interp1 command interpolates between data points. For faster interpolation when x is equally spaced, use the methods '* linear', '* cubic', '* nearest', or '* spline'. 'spline' for cubic spline interpolationĪll the interpolation methods require that x be monotonic.'nearest' for nearest neighbor interpolation.Out of range values are returned as NaNs. If Y is a matrix, then the interpolation is performed for each column of Y and yi will be length(xi)-by- size(Y,2). The vector x specifies the points at which the data Y is given. Returns vector yi containing elements corresponding to the elements of xi and determined by interpolation within vectors x and Y.

The default or factory-set password your Wi-Fi router comes with is usually similar to others and easier to guess than custom passwords. A password also helps stop potential scammers and cybercriminals from intercepting any data sent or received by your laptop, computer or tablet. There are probably enough people in your home already competing for Wi-Fi signal-the last thing you need is neighbors showing up to your Wi-Fi party uninvited. Setting up a strong password is one of the easiest ways to keep unwanted devices off your home network and ensure it's protected. How to block devices from your Wi-Fi network If you're still encountering Wi-Fi dead zones, perhaps due to your home having a unique layout or several interior brick walls, you might also consider a wireless mesh network to create a more stable connection. Sync it with your router by pressing the button labeled WPS, and you're good to go. Pick a spot that's near an outlet and in between your router and the device you want to connect. Setup steps for Wi-Fi extenders vary slightly by brand, but generally speaking, they're pretty easy to set up and immediately use. A Wi-Fi range extender, also known as a Wi-Fi repeater, boosts your network by receiving the wireless signal from the router, and then rebroadcasting it farther into your home. Now what? A Wi-Fi extender may be your answer. So, you've followed the steps to boost your Wi-Fi signal strength, but it's still not quite enough. Look for updates on your router admin page. For optimal signal boost, find an elevated spot that's off of the floor.Īnother handy tip to boost Wi-Fi signal strength is to regularly reboot your router and keep its software up-to-date. Look for an open space in the center of your house that is away from other devices. The easiest way to boost the Wi-Fi signal strength in your house is to find the best spot to place your router.

Ready to hit the road? You'll want to make sure you have a tuner that can take a bit of a beating.įor all their convenience, clip on tuners tend to be a bit more delicate than bulletproof stompboxes. Clip on tuners generally run on small batteries like the CR2032 battery, though recently we've seen an influx of tuners capable of recharging via USB. Most guitar tuner pedals can run independently on a 9V battery, but it's best to double check with whichever tuner you're interested in. Powerĭon't want to be tethered to a power supply? There are, of course, exceptions to these rules. Generally speaking, most standard tuning pedals will fall into the $100 range, while strobe tuners will be a bit more expensive. Clip on tuners are generally the less expensive option, with some tuners like the Stark ST-8 starting at under $20.

A good example is the transparency effects (also known as raster effects, something that is a bit heavy to emulate) in MAME2003-Plus's neogeo emulation, they are a bit broken (the transparency effect is done through blinking, however the blinking is way too visible in MAME2003-Plus) and i doubt there is any plan to fix them.Īnother reason to use FBNeo over MAME2003-Plus for neogeo emulation would be runahead support.RetroArch 1.16.0 has just been released. Or not, the purpose of MAME2003-Plus is to stay playable fullspeed on a Pentium 3 733Mhz (the Xbox OG the author own), fixes that would involve a major performance impact would be dismissed. If you find one, there's as issue tracker, it can be fixed, just like with any other maintained software. That doesn't happen with MAME 2003-Plus and yes, it is a very important thing to consider, so I wouldn't dismiss it so easily.Įxcept you are wrong about that, MAME2003-Plus is also updating romsets from time to time, i know first place since the author (arcadez) is a good friend of our team (i'm a FBNeo dev btw), and sometimes he needs a bit of help to hook new mcu dumps. Oh, so this was also about the romsets not ease don't say the same thing twice in 2 different ways, this is confusing, you make it sound like there are multiple reasons. There are pros and cons to both cores and you can just pick the reasons you care the most about. Now that all cards are on the table, everyone can make an informed decision by themselves. But there can be good reasons to use another emulator. I use FBNeo for those, just not for NeoGeo due to the reasons above. That doesn't happen with MAME 2003-Plus and yes, it is a very important thing to consider, so I wouldn't dismiss it so easily. Yes, it is too much of a hassle, specially for people who don't know how arcade emulation works, which is most people.Īlso, you only find out that your game broke the exact moment you want to play it, which is the worst possible moment, even if once in a decade. Is downloading the newer version of a few romsets every 10 years such a big deal ? There are no obvious bugs on NeoGeo games. It's actively maintained for compatibility fixes. Just look at the neogeo changelog between mame 0.78 and now It won't break your games that are already working. I mean backwards incompatible changes are not accepted. You said "it's stable", meaning it's not crashing i guess ? dozens of fixes, literally, just look at the neogeo changelog between mame 0.78 and now, there are more than an hundred lines and most of them are fixesĪnd with FBNeo, you can even use retroachievements. Now some real reasons to use a more recent emulator : Neogeo games aren't something that has been constantly redumped over the years, and there is always a very good reason for redumoing something, most of the time that means the older dump was corrupt and prevented the game to actually work as it should. you said "the romset is stable", which means "the romsets aren't changing" i guess, the lazyness argument, fine, but actually most neogeo dumps from mame2003-plus are still usable with more recent emulators. you said "it's stable", meaning it's not crashing i guess ? well, it's not as if neogeo emulation was something very unstable in other emulators either, so how is that even an argument ?
