![]() With the right set of parameters, you can get the git log command to show you the history of just our single file: $ git log - index.html The first thing we have to find out is which exact revision we want to restore. That’s when you want to turn back time, but only for this specific file and not for the whole project! For example, you know that index.html was working fine at some earlier point in time, but now it’s not. Sometimes you’ll want to restore a specific file to specific revision. Resetting a Specific File to a Previous State After the process is finished, you can see that only the first, valuable chunk of changes survived - just like we wanted! You’ll notice that I typed “n” for the first chunk (in order to keep it) and “y” for the second chunk (in order to discard it). ![]() Git will then take you by the hand and ask you - for every chunk of changes in that file - if you want to discard it or not. Some of the changes we made in this file are actually great, while only some of them need to be undone.Īgain, git restore comes to the rescue - but this time with the -p flag, because we want to go down to the “patch” level: $ git restore -p index.html Our second problem in index.html is a little bit more tricky. But because git checkout has so many different jobs and meanings, I strongly prefer the slightly newer git restore command (which is focused solely on these types of tasks). Note that, alternatively, I could have used the git checkout command to achieve the same outcome. Let’s undo all of them and recreate the last committed state of that file: $ git restore css/general.css The changes we made went in a totally wrong direction. Let’s tackle the problem in general.css first. You don’t need Tower to follow along with this tutorial. Note: for a better overview and clearer visualization, I’m using the Tower Git desktop client in some of my screenshots. Let’s take a look at an example scenario with some “local” changes (aka changes we haven’t committed, yet). Here’s where Git can help you: it allows you to keep what’s good and discard the changes that you don’t want anymore. In other words: some of the code that you’ve produced is great … but some of it not so much. At times, it feels like you’re taking two steps forward and one step back.

This analyzer displays the loudness of each frequency in a 2D or 3D graph over time. Another similar kind of analyzer is a sonograph/spectrograph. You can analyze a reference song using a spectrum analyzer and EQ your song’s master until it somewhat matches your reference spectrum to get a similar sound. And Loudness Range shows, as an example, how different the loudness of your verse and chorus section is.Ī frequency spectrum displays how loud each frequency is in your audio in real-time. Thus, dynamic Range is useful for measuring how compressed elements such as drums, vocals, etc., are in your song. However, Dynamic Range does so using peak metering (fast), while Loudness Range uses Loudness Unit (slow). Both measure the range between the loudest and the quietest parts of your audio. There are two kinds of ranges : Dynamic Range and Loudness Range. For example, audio with a thin line at the middle of such an analyzer is mono audio, whereas a moving, spaghetti-like visualization signifies stereo. This analysis shows how wide the stereo field of your audio is. So, for example, if you listened to a 60Hz sinewave and an 800Hz at 30dB amplitude, you would perceive the 60Hz sinewave as quieter than the 800Hz. To simplify, our ears do not hear all the frequencies at the same level. LUFS is the same as RMS, except this unit considers human ear perception. However, some plugins let you adjust the time window as well. Generally, this period of time is 300 milliseconds. RMS is the average amplitude level over a certain period of time. This is important becaus e if your True Peak is higher than 0dB, it could cause clipping on analog amplifiers/players. In contrast, the regular peak meters we see in our DAWs calculate the same thing on a digital system. True Peak is the highest point an audio signal reaches on an analog system. Let us have a look at some of the information provided by such plugins: So, with a metering plugin, we can make sure our masters are compliant with our intended platform’s standard. Streaming platforms use this information to assure consistency of their content. It also comes with Fl studio so it makes sense that he mentions it.8 Readings that you may like: What Do A Metering Plugins Do?Ī metering plugin analyzes any audio you feed into it and provides various kinds of information about it. For the size of the edits that were made, Fruity limiter is perfectly adequate. Of course you're not going to double the gain or drop the threshold to nearly nothing, that's not mastering. This is an article about mastering in fl studio. Your dislike of the Fruity Limiter is also quite irrelevant. ![]() Cutting these frequencies out adds clarity to the music as humans can't recognise harmonics in this range. It is only ever detected by human hearing as very deep noise, if it is detected in the first place. In a song written for a diatonic scale it makes absolutely no sense to have any sound coming from these frequencies. Any sound below 40Hz is difficult to hear and cannot be distinguished as a note. It's completely irrelevant to the fact that humans can hear down to 20Hz and all to do with the effect that the cut actually has on the sound. It's quite normal to cut out frequencies below 40Hz. I don't think your criticism is particularly constructive. Tip 6: Fruity Limiter has an unprofessional algorithm that causes a lot of pumping, even if you increase attack and release times, and can't apply in awful lot of gain.ĭelete this comment if you like, but that doesn't rid the problem. Tip 3: Dynamic range compression and lossy compression are 2 completely different things, you won't lose high end freqs from dynamic range compression, and even if you did, this parametric EQ would not help recover these frequencies, because they're not there and you'd only be boosting the slightly lower ones. On top of this, the parametric eq in the picture is cutting valuable frequencies even above the stated 40hz and is even slightly affecting up to 130hz, which is nonsense. Not only can we hear downwards of 25 or even hear 20hz, many headphones and good speakers will have a frequency range travelling well below 40hz. Tip 1: Cutting below 40hz is barbaric in many genres. ![]() This article really misinforms readers, and here's why: I believe when writing for a big website such as this one, it's very important to be accurate, as people can get stuck with "tips" on the net for a long time, delaying their production skills. ![]() ![]() I don't wish to hate, but I think constructive criticism is necessary here. ![]() For specific directions, visit our website.

Discovery ( WBD) which have launched newer streaming channels Disney Plus (2019) and HBOMax (2020), respectively. The segment is led by Netflix ( NFLX), which has been in the streaming industry since 2007, in addition to companies like Walt Disney ( DIS), and Warner Bros. Streaming is still in its relatively early stages-so there’s potentially more room for growth. ![]() ETFs like the VanEck Video Gaming and eSports ETF ( ESPO) and the First Trust S-Network Streaming and Gaming ETF ( BNGE) stand out for focusing on streaming audio, video, and gaming companies which have grown in popularity over the past few years - particularly video streaming and rental which has been able to take market share from both cable and satellite TV and movie theaters. Media companies are similarly evolving from live TV to video-on-demand to streaming. Telecom companies were once essentially utilities and now they’re evolving along with technology, social media, and other trends. The communications sector is one of the fastest changing sectors.Īs alluded to above, the communication sector continues to evolve over the years. For investors who want more diversification away from those two companies and small-cap exposure, the Invesco S&P 500 Equal Weight Communication Service ETF ( EWCO) has only 10.1% allocation to these two stocks due to its equal weight methodology. The two companies make up 46.5% of XLC, 35.4% of VOX, 39.6% of FCOM, and 36.5% of IXP. For market-cap weighted communication ETFs like XLC, Meta Platforms and Google make up one-third to close to a half of the ETF’s weight. The Communication Services Select Sector SPDR Fund ( XLC) is up 22.2% YTD relative to the Technology Select SPDR Fund ( XLK) which is up 18.6%. Most communication sector ETFs have actually been outperforming technology ETFs YTD. The sector was formed after media companies and internet services companies joined traditional telecommunications companies like AT&T ( T) and Verizon ( VZ). Internet companies like META and Alphabet ( GOOGL/ GOOG) are actually considered part of the communication services sector after a GICS reclassification in September 2018. What do communication ETFs really look like? number of users since ad revenue is typically based on clicks or impressions delivered (which increases with time spent). Engagement and time spent on the apps would hold equal or maybe even more weight vs. Its monthly active users have grown slowly between 0% – 2% in each of the last seven quarters, which is mostly driven by countries like India, Nigeria, and Bangladesh. For Meta’s family of apps (including Facebook, Instagram, and WhatsApp), this aligns with its historical user growth. These figures are from February 2021, so the percentage is likely larger in 2023. adults own a smartphone and 77% own either a desktop or laptop. A large majority of people in developed countries already own at least one device, so additional devices or replacement devices won’t necessarily grow the number of active users. ![]() In contrast to manufacturers which earn money from device or hardware sales, companies like Meta Platforms ( META) generate substantially all of their revenue from advertising, which is driven by user engagement. Meanwhile, other internet-related companies may be less sensitive to changes in PC, smartphone, or even semiconductor inventory. Like most other computer manufacturers, most of Apple’s net sales are derived from its devices (iPhone, Mac, iPad, Wearables and Home Accessories), while the services segment is currently only 17.7% of its net revenues for the most recent quarter ending December 2022. There was increased demand for personal computers during the pandemic, which has since diminished.ĭuring its earnings call in February, Apple ( AAPL) had already warned that sales for Macs and iPads would decline by double digits in the quarter. These issues are expected to persist until at least the middle of the year, but this hasn’t been a complete surprise. All of the top manufacturers saw declines of 24% to 40% in shipments including Lenovo, HP, Dell, Asus, and Apple (Apple was down the most at 40.5% y/y). While investors have renewed interest in the tech sector this year, this week, however, the sector lagged with news of PC shipments falling 29% y/y globally in 1Q23 due to excess inventory and decreased consumer demand. ![]()
![]() The one exception is if the S 0-S 1 transition is the maximum on both spectra, which would mean having the excitation and emission monochromators set to the same wavelength. Provided you have a computer data base of mass spectra, any unknown spectrum can be computer analyzed and simply matched against the data base.\), that would correspond to an excitation wavelength of 360 nm and emission wavelength of 402 nm. The 43 and 71 lines are missing from the pentan-3-one spectrum, and the 57 line is missing from the pentan-2-one one.Īs you've seen, the mass spectrum of even very similar organic compounds will be quite different because of the different fragmentation patterns that can occur. ![]() You don't need to worry about the other lines in the spectra - the 43, 57 and 71 lines give you plenty of difference between the two. In that case, you would get a strong line at 57. With pentan-3-one, you would only get one ion of this kind: That would give you strong lines at m/z = 43 and 71. In the pentan-2-one case, there are two different ions like this: pentan-2-oneĮach of these is likely to split to produce ions with a positive charge on the CO group. Suppose you had to suggest a way of distinguishing between pentan-2-one and pentan-3-one using their mass spectra. Using mass spectra to distinguish between compounds In these two spectra, this is probably the most dramatic example of the extra stability of a secondary carbocation. You would get the same ion, of course, if the left-hand CH 3 group broke off instead of the bottom one as we've drawn it. Again a secondary carbocation is formed - this time, by: The peak at m/z = 57 is much taller than the corresponding line in pentane. The ion formed is a secondary carbocation - it has two alkyl groups attached to the carbon with the positive charge. This peak in 2-methylbutane is caused by: This is caused by a different ion than the corresponding peak in the pentane mass spectrum. Look first at the very strong peak at m/z = 43. 2-methylbutane is an isomer of pentane - isomers are molecules with the same molecular formula, but a different spatial arrangement of the atoms. ![]() Let's look at the mass spectrum of 2-methylbutane. A split producing a tertiary carbocation will be more successful still. Summarizing the most important conclusion from the page on carbocations:Īpplying the logic of this to fragmentation patterns, it means that a split which produces a secondary carbocation is going to be more successful than one producing a primary one. For example, the mass spectrum of pentane looks like this: All sorts of fragmentations of the original molecular ion are possible - and that means that you will get a whole host of lines in the mass spectrum. The ion, X +, will travel through the mass spectrometer just like any other positive ion - and will produce a line on the stick diagram. These uncharged particles will simply get lost in the machine - eventually, they get removed by the vacuum pump. Only charged particles will be accelerated, deflected and detected by the mass spectrometer. The uncharged free radical will not produce a line on the mass spectrum. The simplest case is that a molecular ion breaks into two parts - one of which is another positive ion, and the other is an uncharged free radical. The molecular ions are energetically unstable, and some of them will break up into smaller pieces. That's one half of what was originally a pair of electrons - the other half is the electron which was removed in the ionization process. The dot in this second version represents the fact that somewhere in the ion there will be a single unpaired electron. This ion is called the molecular ion - or sometimes the parent ion and is often given the symbol M + or. These electrons have a high enough energy to knock an electron off an organic molecule to form a positive ion. When the vaporized organic sample passes into the ionization chamber of a mass spectrometer, it is bombarded by a stream of electrons. |
