On the one hand, part of living in the open source world is understanding that other people can and will develop parallel projects. That was a journey, but what about that open letter LibreOffice sent to the Apache project earlier this month? We could argue on either side of the letter. This is further complicated by issues with IBM providing some code from Lotus Symphony that may not have been properly placed into the open source domain. If you want the details, you can read this contemporary post from the Free Software Foundation. But if LibreOffice adds something, take font embedding, for example, OpenOffice can’t legally incorporate that code. OpenOffice uses the Apache License, whereas LibreOffice uses a dual LGPLv3/Mozilla Public license.įor some legal reasons, then, anything OpenOffice does can be incorporated into LibreOffice, the terms of the license permit that. We aren’t open source lawyers - or any kind of lawyers, for that matter - but one of the problems stems from how the two projects have their licenses. They have had 13 major releases, while OpenOffice hasn’t had a major release in six years. According to the LibreOffice letter, they’ve had 15,000 code commits in 2019 compared to 595 in OpenOffice over the same period. LibreOffice has been under very active development since then, and most Linux distributions now use it as their default office suite. When Oracle came on the scene, most of the OpenOffice developers formed LibreOffice. The timeline is a bit of a head scratcher but Wikipedia has this great graphic that lays it out: While there have been several notable forks including NeoOffice and Go-oo, only LibreOffice has really been robust, even though NeoOffice and the original OpenOffice are still active. Of course, once the code went open source around 2000, people were free to create derivative projects and they did. They gave responsibility over to the Apache Software Foundation.Īpparently, though, StarOffice 5.1 will still run on Windows 10 as demonstrates in the following video: In 2011, Oracle decided to kill the commercial offering, leaving OpenOffice, the official community-based keeper for the StarOffice flame. For example, StarOffice 9 was no longer free for educational customers, but they could use StarOffice 8 or, of course, just stick with OpenOffice and forego support. They also did strange things with licensing. They renamed the program Oracle Open Office. They didn’t seem to have much of a plan for some of the things they bought and StarOffice was one of them. A couple of years later, StarOffice 8/OpenOffice 2.0 appeared and by 2008, we had StarOffice 9 with OpenOffice 3.0 just before Oracle entered the picture. In 2003, release 1.1 turned into StarOffice 7. StarOffice 6.0 corresponded to OpenOffice 1.0. This was the state of affairs for a while. Sun contributed to the project and would periodically snapshot the code to market future versions of StarOffice. It eventually released much of the code under an open source license producing OpenOffice. Sun provided StarOffice 5.2 in 2000 as a free download for personal use, which gave the software a lot of attention. The story was that it was still cheaper than buying a license for each Sun employee, particularly since most had both a Windows machine and a Unix machine which still required some capability. We don’t mean they bought a copy or a license, they bought the entire thing for just under $74 million. The program was far less expensive than most competitors, costing about $70, yet in 1999 that price point prompted Sun Microsystems to buy StarOffice. Eventually, the company added other office suite programs and with support for DOS, OS/2, and Windows, the suite became known as StarOffice. By 1986, he created a company, Star Division, porting the word processor to platforms like CP/M and MSDOS. It all started when German Marco Börries wrote StarWriter in 1985 for the Zilog Z80. But it did get us thinking about how things got here. We could argue that case either way, but we won’t. LibreOffice, on the other hand, is a very active project. Their logic is that OpenOffice has huge name recognition, but hasn’t had a new major release in several years. However, the LibreOffice team recently penned an open letter to the Apache project - the current keepers of OpenOffice - asking them to redirect new users to the LibreOffice project. That isn’t surprising since they both started with exactly the same code base. When it comes to open source office suites, most people choose OpenOffice or LibreOffice, and they both look suspiciously similar.

When servo motor is commanded to move by applying pulses of appropriate width, the shaft moves to and holds the required position. The servo turns to the 90˚ with the pulse of width 1.5 milliseconds. The servo moves with the pulse of 1 millisecond to turn motor towards 0˚ whereas a pulse of 2 milliseconds to turn motor towards 180˚. There are 3 terms that are used to control the servo motor: The width of the pulse controls the angular position of the rotating shaft. The width pulse is varied in the range of 1 millisecond to 2 milliseconds and transfer this to the servo motors with repeating 50 times in a second. These send electric signals of inconsistent width to the motor. The servo motors can be controlled by Pulse Width Modulation (PWM). Thus, a comparator is used to decide the ON/OFF position.Ĭontrolling of Servo Motor Using PWM Signal The motor gets ON for the desired time when the logical difference is higher and the motor gets OFF for the desired time when the logical difference is lower. Comparator signal is called a logic signal of the motor. On the basis of the feedback signal, the motor starts working. The input signal for the motor is termed as a feedback signal. For producing an output signal, the comparator is used to compare the required reference signal and the output signal is sensed by the sensor. This controller is composed of a comparator and a feedback path. The controller is required for this closed-loop system. The servo motor works on the phenomenon of the automatic closed-loop system. Shaft: The armature winding is coupled on the iron rod is known as the shaft of the motor.Įncoder: It has the approximate sensor which determines the rotational speed of motor and revolution per minute of the motor. It is also known as an armature winding of the motor.īearing: This is of two types, i.e font bearing and back bearing which are used for the movement of the shaft. Rotor Winding: This wound on the rotating part of the motor. It is also known as field winding of the motor. Stator Winding: This wound on the stationary part of the motor. The Servo motor is DC motor which has 5 following parts: There are many types of servo motors and their main feature is the ability to precisely control the position of their shaft. Servomotors are not a specific class of motor although the term servomotor is often used to refer to a motor suitable for use in a closed-loop control system. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors. It consists of a suitable motor coupled to a sensor for position feedback. But before that let’s learn about the servo motor it’s working and also its applications.Ī servo motor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration. We will interface 4 servo Motors with Arduino and control its rotational movement using Pulse Width Modulation Signal. In this tutorial, we will learn How to Control Multiple Servo Motors with Arduino. 6 How to Control Multiple Servo Motors with Arduino.5 Controlling of Servo Motor Using PWM Signal.

CameraBag lets you include a watermark in any preset, or saved as its own preset that you can then layer on top of any other adjustments or preset, easily visible and adjustable in the main interface. Easy watermarking: Lightroom Classic has an antiquated watermark dialog, but recent Lightroom versions include no watermark support.These include analog film emulation, popular modern digital styles, grain packs, color correction toolsets, and specific filters to help with different portrait and landscape scenarios. Hundreds of high-quality included presets: CameraBag includes hundreds of professionally-focused editable presets.Applying grain before or after sharpening can make a huge difference in the final look of an image - there's no way to control which happens first in Lightroom. It's trivial to rearrange them, toggle them on and off, go in and edit their values, etc. Layerable adjustments/presets: Every adjustment applied in CameraBag appears, in the order they’re applied, as a tile in the bottom tray.These include curve-based color adjustments (see, for example, CameraBag’s Coloring Curve, Hue Exposure, and Hue Saturation adjustments), filtered black and white conversion, advanced grain controls, and more. Advanced Tools: CameraBag contains many tools and adjustments which simply don't exist in Lightroom.This is ideal for wedding photographers or anyone else who wants to develop a signature style and apply it across multiple photos and videos. Video support (CameraBag Pro only): Everything you can do to an image in CameraBag Pro, you can do to videos with the exact same tools.Many things! Here are some of our top picks: This is especially baffling because CSV parsers are trivially easy to write (I wrote one in C and plumbed it into PHP a year or two ago, because I wasn't happy with its native CSV-handling functions. How did they manage to overcomplicate something as simple as CSV? MS SQL Server exporting broken, useless CSV.Don't trust anyone who doesn't know what these things are) They are fundamental concepts in literally every human-readable data serialisation specification. MS SQL Server throwing an error message because it doesn't understand quoting or escaping (contrary to popular belief, quoting and escaping are not exotic extensions to CSV.MS SQL Server's text encoding handling going wrong.MS SQL Server silently truncating a text field.Then, at some point, they see for themselves. Most people don't believe me when I tell them this. MS SQL Server can neither import nor export CSV. It makes sense: would you rather find out your import went wrong now, or a month from now when your client complains that your results are off?) (This may sound fussy or inconvenient, but it is actually an example of a well-established design principle. The slightest whiff of a problem and it abandons the import and throws a helpful error message. If PostgreSQL says your import worked, then it worked properly. Importantly, they will not silently corrupt, misunderstand or alter data. When an error occurs, they give helpful error messages. The COPY TO and COPY FROM commands support the spec outlined in RFC4180 (which is the closest thing there is to an official CSV standard) as well as a multitude of common and not-so-common variants and dialects. Let's not understate this: a data analytics platform which cannot handle CSV robustly is a broken, useless liability. In practice, this means that it needs to be able to ingest and excrete CSV quickly, reliably, repeatably and painlessly. All RDBMSes can dump data into proprietary formats that nothing else can read, which is fine for backups, replication and the like, but no use at all for migrating data from system X to system Y.Ī data analytics platform has to be able to look at data from a wide variety of systems and produce outputs that can be read by a wide variety of systems. CSV supportĬSV is the de facto standard way of moving structured (i.e. This section is a comparison of the two databases in terms of features relevant to data analytics. Why PostgreSQL is way, way better than MS SQL Server Do please use it if you wish I will do my best to respond.ĭISCLAIMER: all the subjective opinions in here are strictly my own. Maybe MS SQL Server kicks PostgreSQL's arse as an OLTP backend (although I doubt it), but that's not what I'm writing about here, because I'm not an OLTP developer/DBA/sysadmin.įinally, there is an email address at top right. I am comparing the two databases from the point of view of a data analyst. If I find out that I've got something wrong, I'll fix it. I have done my honest best to get my facts about MS SQL Server right – we all know it is impossible to bullshit the whole internet. I know it's not scientifically rigorous to do a comparison like this when I don't have equal experience with both databases, but this is not an academic exercise – it's a real-world comparison. Where I have made claims about MS SQL Server I have done my best to check that they apply to version 2014 by consulting Microsoft's own documentation – although, for reasons I will get to, I have also had to rely largely on Google, Stack Overflow and the users of the internet. Unless otherwise stated I am referring to PostgreSQL 9.3 and MS SQL Server 2014, even though my experience with MS SQL Server is with versions 2008 R – for the sake of fairness and relevance I want to compare the latest version of PostgreSQL to the latest version of MS SQL Server. This document is my way of automating that conversation. A well-known principle in IT says: if you're going to do it more than once, automate it. Over the years I have discussed the issue of PostgreSQL vs. I frequently come into contact with people who know very little about these things – although some of them don't realise it. I have spent that decade dealing with data, database software, database hardware, database users, database programmers and data analysis methods, so I know a fair bit about these things. I have been doing this for about a decade. I work as a data analyst in a global professional services firm (one you have certainly heard of). A comparison of two relational databases from the point of view of a data analyst 0. We tried MINDFUL GRAY in the master bedroom. It wasn’t too blue next to it, instead, it complemented it well. I liked how this looked next to the tan tile. We used REPOSE GRAY for the bathrooms and the guest room. This light gray was my favorite so we used it in the main room, kitchen, and hallways. We went with GRAY OWL in an eggshell sheen for a majority of the apartment. Less stress for us, and perfectly painted walls. There was no way we could pack, paint, and work at our jobs and make it into our new home in time. I know what you’re thinking….this is the DIY Playbook and you didn’t even paint yourself? We decided to hire a pro because of the short timeline in between closing on our home and moving into our new space. Or you can check out this comprehensive post with lots of tips for picking the perfect paint color.Īfter checking out all of the shades in our rooms, we picked our favorites and gave the colors to the painter. If you have white trim, hold up a piece of white paper next to each shade so you can understand how it will look next to the white.Paint the color next to other key elements in the room (the kitchen cabinets, the tile in the bathrooms, etc.).Make sure you paint on a large enough sample so you can see the color from afar.Here are a few tips for painting the samples on… It’s crazy because the paint colors looked sooooo different in every space! Finn thought I screwed something up because once we decided on a color, we would walk to another room and be perplexed as to how it could look so different. Make sure you don’t mix up the colors as you go. I then proceeded to paint the samples in every single room in our place. Each one only cost a couple bucks, so it’s absolutely worth it to buy samples and try the colors out on your walls. I purchased samples (which come in quarts at Lowe’s…that’s a lot of paint!) so I could easily try out each shade on the wall. We used both “Argos” & “Passive” in our Chicago apartment, so I was very familiar with them. Sherwin Williams #6002 “Essential Gray”.Not exactly scientific research, but it certainly helped me narrow down my choices. I started researching online, which for me involves a combination of blog reading, Pinterest searching, looking at paint swatches, google image searching specific colors, and reading home decor articles about the best shades for each brand. I decided that I needed to narrow down my choices from about 50 shades to 6 shades. So for me, it was gray all the way from the start. Plus, so much of our home decor works well with gray. I’m a sucker for gray and I love the way it looks with white trim and dark floors. I knew that I wanted to go gray before we even moved in. But let’s backtrack a little bit here so we can chat about how I decided upon all of the new colors for our home (which I’m now calling Augusta…since that’s the street we live on). Gotta love how a new color can make a room look and feel so much different. …and now I am here to prove to you that this statement is oh-so-true!Īm I right? Dang. We’ve all heard it before… PAINT CAN TRANSFORM A SPACE Step 2: When prompted, connect the AppleTV to your computer via USB. Step 1: Open Seas0nPass and select the ‘Boot Tethered’ option. Note: The Apple TV MUST be disconnected from the computer (for at least a brief moment) after restoring in iTunes for the tethered boot process below to work properly. This means it must be connected to a computer for a brief moment during startup. Please proceed to the ‘tethered boot’ section below.Īfter jailbreaking your atv on iOS 4.3 with Seas0nPass your device requires a tethered boot. Step 6: iTunes will confirm the restore when complete – your AppleTV is now jailbroken. Step 5: iTunes will open automatically and start the restore process. Step 4: When prompted, connect your AppleTV using a micro-USB cable (leave power disconnected), and hold both the ‘MENU’ and ‘PLAY/PAUSE’ buttons for 7 seven seconds. Step 3: The latest AppleTV software will be downloaded and used to create a custom ‘jailbroken’ software file. (if already jailbroken, and you just need to do a ‘tethered boot’ scroll down). Step 2: If your AppleTV is not yet jailbroken, select ‘Create IPSW’. Step 1: Unzip the ‘Seas0nPass.zip’ file and launch Seas0nPass.
