I remember Lincoln Enterprises very quickly made the rank-on-either-side-of-the-Starfleet-delta pins available after this episode totally got one of those. I’m guessing they had Frakes re-loop that line of dialogue before sending the episode itself up a week after the trailers.) (The promos accompanied the previous week’s show on the satellite feed in two forms, one with whatever background music Paramount preferred, and one with no announcer or music, nothing but the show dialogue and sound effects, for local stations to dress up how they wanted if they preferred their own announcer or standard music bed. One very weird thing I distinctly remember from the original satellite promo feed was that Riker pronounced charade as “sha-ROD” in the promos, but in the finished episode prounounced it “sha-RAID”.

Our one byte checksum example could have been calculated with the following function (in C language) that we call repeatedly for each byte in the input string. In fact checksum calculations as described above can be defined in this way. Use a function F(bval,cval) that inputs one data byte and a check value and outputs a recalculated check value. The idea behind a check value calculation is simple. So calculating a checksum may be a simple method for detecting errors, but doesn’t give much more protection than the parity bit, independent of the length of the checksum. Even if we had used a four byte long checksum we would not have detected this transmission error. The checksum for this new string is still 210, but the result is obviously wrong, only after two bits changed. The receiver will than see the array representing the string “ M`mmert“. Let us assume that in our example array the lowest significant bit of the character ‘ L‘ is set, and the lowest significant bit of character ‘ a‘ is lost during communication. They often fail in bursts, or due to electrical spikes. In practice, bits do not change purely random during communications. Seems rather good, but this is only theory. We might conclude that with a four byte checksum the chance that we accidentally do not detect an error is less than 1 to 4 billion. Using a two byte checksum will result in 65,536 possible different checksum values and when a four byte value is used there are more than four billion possible values. In this example we have used a one byte long checksum which gives us 256 different values. ![]() You can use the calculator above to check this result. The one byte checksum of this array can be calculated by adding all values, than dividing it by 256 and keeping the remainder. The example string is “ Lammert” which converts to the ASCII values. Lets take an example string and calculate a one byte checksum. It is certainly easier to calculate a checksum, but checksums do not find all errors. One might think, that using a checksum can replace proper CRC calculations. The answer is simple, they are powerful, detect many types of errors and are extremely fast to calculate especially when dedicated hardware chips are used. So let’s see why they are so widely used. Modern computer world cannot do without these CRC calculation. Also each data block on your hard-disk has a CRC value attached to it. All packets sent over a network connection are checked with a CRC. Nowadays CRC calculations are used in all types of communications. The CRC calculation or cyclic redundancy check was the result of this. To overcome this problem people have searched for mathematical sound mechanisms to detect multiple false bits. This simple detection mechanism works if an odd number of bits in a byte changes, but an even number of false bits in one byte will not be detected by the parity check. For serial data they came up with the solution to attach a parity bit to each sent byte. Since the beginning of computer science, people have been thinking of ways to deal with this type of problem. Whenever digital data is stored or interfaced, data corruption might occur. We then simulate different treatment scenarios in low, medium and high transmission settings, comparing once yearly mass drug administration (MDA) with more frequent MDA and higher coverage. We validate the model by fitting to a first time point and predicting future timepoints from surveillance data in Kenya and Sri Lanka, which have different vectors and different stages of the control programme. We develop a new individual-based, stochastic mathematical model of the transmission of lymphatic filariasis. Modelling can assist in identifying what data should be collected and what strategies are best for which scenarios. You might also have to place the first version of the splash_screen.xml into drawable-v24 as android defaults to the closest drawable-vXX folder it can find for resources.With ambitious targets to eliminate lymphatic filariasis over the coming years, there is a need to identify optimal strategies to achieve them in areas with different baseline prevalence and stages of control. The issue is that you have to use the aproach with the aditional drawable folders as the second version of the splash_screen.xml file will lead to your splash screen not being shown at all on devices running APIs higher than 23. place the following code in the Layer-list of the splash_screen.xml file that you create in these folders: įor some reason for these APIs you have to wrap your drawable in a bitmap in order to make it work and jet the final result looks the same. This serves to tell your phone to redirect to files placed in those folders whenever the relevant device runs an API corresponding to the -vXX suffix in the drawable folder, see this link. You need to create a second file named exactly like the splashscreen xml (lets say splash_screen.xml) and place it into 2 folders called drawable-v22 and drawable-v21 that you will create in the res/ folder (in order to see them you have to change your project view from Android to Project). After tearing my eyebrows out for half a day I finally brute-forced a solution by sheer willpower. I noticed that the splashscreen was again trying to fill the entire view and looking like shit. While the solution above works for devices runing API24+ I got really disappointed after installing my app a device running API22. so use a vector drawable by all means (there is a site called vectr that I used to create mine without the hasle of downloading specialized software).ĮDIT in order to make it work also on API21-22-23 ![]() Resolution is finally great as opposed to the pixelated edges I was getting when using bitmap. My code is actually only drawing the triangle in the picture at the bottom but here you see what you can achieve with this. then i just put it in my splash screen drawable like so and it works great: ![]() In the code above I am rescaling a drawable I drew on a 640圆40 canvas to be 240x240. If your logo is distorted or wont fit and you are only targeting APIs24+ you can simply scale down your vector drawable directly in its xml file like so: Unfortunately you also have to provide splash screen as PNG for this to work in the old APIs.īut for every device with API 23+ the vector drawable will be used.Įdited solution that will make your SplashScreen look great on all APIs including API21 to API23įirst of all read this article and follow the GOOD way of making a splash screen. So now, when the PNG is used on pre API 23 devices it will be displayed properly and won't be stretched to the whole background. Then create another drawable_splashscreen.xml but inside the regular drawables folder: So my solution is the following: Create a drawable_splashscreen.xml inside the folder drawables-v23 which looks like the following for the vector drawable. So in the the converted PNG is inserted into the element, which causes the bitmap to stretch to all edges, because it's missing the element. So what is likely happening here is, that on API 21 the Vector get's converted to a PNG to be compatible. The problem is you can't load VectorDrawableCompat outside of the process, like in this case in your themes android:windowBackground. ![]() Unfortunately there does not seem to be a possibility to make the splash screen work with just a vector drawable for pre API 23. ![]() ![]() ![]() However, when listening to playlists with tracks encoded at different sampling rates and/or bit depths, I switch to UAPP, whose equalizer is not nearly as good as PA's (and whose UI is much worse). ![]() Most of the time I use PA with its equalizer, which is very good. +1 to an "Output Follows Source Formatting" mode that avoids resampling. The main time it would be an issue is during All Songs shuffle play, and it would be easy enough to add a second option to allow PA to disable the Format Following feature while shuffling random songs (if the user preferred it that way). Within any given album it's unlikely that the individual tracks would be encoded at different sampling rates or bit-depths anyway, so gapless would still work. I also think the resulting issues with crossfade and gapless may be a bit of a red-herring too. They more accurately want a no resampling mode. People who ask for it often maintain that they would prefer to use PA for all of its other features (such as the EQ) so they clearly are not interested in genuine bit-perfect reproduction which would prohibit any further digital manipulation of the audio path - so no gain/volume, EQ adjustment, crossfade, etc. This may help to keep complaints down if users experiment with the feature while wearing headphones! □Īn "Output Follows Source Formatting" mode would satisfy most of this type of request that I've seen in the forums. Perhaps one step further would be to have an indicator show up on the Now Playing UI to show that this mode is engaged. Pressing OK (or "Are you really sure?") would then enable the feature, or "Cancel" to back out without making the change. Plus I would suggest to further have some sort of second pop-up disclaimer indicating that volume control will be lost, and that the device will output full volume. There again should be a description at this setting that indicates which features may will work if enabled. This would be for those using Poweramp as a dedicated source only. Again crossfade would also need to be defeated in this mode. Second would be to lock a true " Bit Perfect" mode with no duck, EQ, or volume control influence. There should be a description at this setting that indicates which features may not work if enabled. But this should address the request for most that are asking for this IMO. In this mode, things like duck, EQ, and volume can still be used. So enabling this mode would force defeat the crossfade function. Note that in these cases, by definition cross fading between tracks with different rates and frequencies is not possible. So I would ask to have this addressed in two ways if/when an implementation arrives.įirst is to achieve a " No Resample" mode to maintain bit depth and sample frequency while playing on any device. But there are also many that have external DAC solutions, where Poweramp and the user's device strictly become the source. I agree that for the general users that have requested " bit perfect mode" that this may be the case. They are generally more concerned about avoiding any frequency or bit-depth resampling, but they accept simple digital scale changes to adjust the listening level at the output stage.

One person would make sure the official town clock read noon when the sun was highest in the sky each day. Just over a century ago, towns and cities set their own time. People have lived in different time zones for a long time, but it hasn’t always been as organized as it is today. Since different parts of Earth enter and exit daylight at different times, we need different time zones. Noon would be the middle of the day in some places, but it would be morning, evening, and the middle of the night in others. Imagine if the entire Earth had a single time zone. When your location rotates out of sunlight, you see the sun set. As your location on Earth rotates into sunlight, you see the sun rise. As Earth rotates, different parts of Earth receive sunlight or darkness, giving us day and night. Every 24 hours, the Earth makes a complete rotation.

OCB enjoys provable security: the mode is a secure AE scheme, under the standard definition , assuming that the underlying blockcipher E is secure as a strong pseudorandom permutation (PRP). ![]() Computational work beyond blockcipher calls is restricted to a small number of logical operations per call. OCB is fully parallelizable: almost all of its blockcipher calls can be performed simultaneously. OCB is online in the sense that one need not know the length of A or M to proceed with encryption, nor need one know the length of A or the ciphertext C to proceed with decryption. OCB requires a single key K for the underlying blockcipher, and all blockcipher calls are keyed with it. If the AD is fixed during a session, then after processing it the first time, there is effectively no computational cost for subsequent authentications of it and the addend of a should be ignored. If the nonce is implemented as a counter and the implementation caches a secret 16-byte value with each message encrypted, then \(63/64\approx 98\%\) of the time the number of blockcipher calls can be reduced to \(m+a+1\). Encryption needs at most \(m+a+2\) blockcipher calls, where \(m = \lceil |M|/128\rceil \) is the block size of the plaintext and \(a = \lceil |A|/128\rceil \) is the block size of the AD. OCB does its work using a 128-bit blockcipher E. The nonce, a string of 120 or fewer bits, must be unique to each encryption call. OCB encryption protects both the confidentiality and authenticity of a plaintext M and, additionally, the authenticity of an associated data A and nonce N. When we speak of OCB in this paper, we will henceforth mean OCB3. We update the proceedings paper on OCB3, freshening all of the experimental results, expanding the proof, and placing the entire enterprise in context. This paper is about OCB3: its definition, development, security, and software performance. It is specified in RFC 7253 and was selected for the CAESAR final portfolio. ![]() The final version of OCB, called OCB3 (2011) , corrected some missteps taken with OCB2 and achieved the best performance yet. OCB2 was recently found to have a disastrous bug . A second version, now called OCB2 (2004) , added support for associated data (AD) and redeveloped the mode using the idea of a tweakable blockcipher . The first, now called OCB1 (2001) , was motivated by Charanjit Jutla’s IAPM . It is a blockcipher mode of operation, the blockcipher usually being AES. OCB is a well-known algorithm for achieving this aim. Schemes for authenticated encryption (AE) symmetrically encrypt a message in a way that ensures both its confidentiality and authenticity. |
