Rails 6 introduced a new configuration option implicit_order_value for ApplicationRecord classes. It results in a seemingly buggy behavior of first and last methods before Rails 6 because, by default, they implicitly sort relations by ID values. Unfortunately, it has nothing to do with when it was generated compared to other UUID values from the same table. It means that a single UUID from the table will always have the first place when sorting. PostgreSQL can still sort them using the deterministic algorithm. On the contrary, due to the totally random nature of UUID, it is generated in a non-sequential order. We can safely assume that the most recently created object will have the highest ID value. Integer primary keys are generated sequentially. Let’s take a look at an SQL query generated by running User.last SELECT * FROM users ORDER BY id DESC LIMIT 1 Apparently first and last ActiveRecord::Relation methods no longer worked as expected, returning a seemingly random object from a collection. ![]() UUID order issuesīefore Rails 6, trying out UUID in your app might have been a bit discouraging. ![]() Running this code snippet will not raise an error but rather create a new user object, with id randomly generated by the database. Otherwise, you need to remember to cover these cases.Īnother surprise will happen if you want to create objects with predefined UUID values that might be incorrect: User. It should not affect your logic as long as you use UUIDs only as primary keys, because they cannot be nil. Invalid UUID value is implicitly converted to nil to avoid database level error. It generates the following SQL query: SELECT "users". Consider the following code snippet: User. One surprising feature of ActiveRecord is how it treats invalid UUID values. You need to follow the similar steps of adding a new GUID type column and based on the value from old integer foreign key, you must assign correct UUID keys. I will not go into details on how to migrate associations because it will differ for every use case. class AddUUIDToUsers < ActiveRecord :: Migration def up add_column :users, :uuid, :uuid, default: "gen_random_uuid()", null: false rename_column :users, :id, :integer_id rename_column :users, :uuid, :id execute "ALTER TABLE users drop constraint users_pkey " execute "ALTER TABLE users ADD PRIMARY KEY (id) " # Optionally you remove auto-incremented # default value for integer_id column execute "ALTER TABLE ONLY users ALTER COLUMN integer_id DROP DEFAULT " change_column_null :users, :integer_id, true execute "DROP SEQUENCE IF EXISTS users_id_seq" end def down raise ActiveRecord :: IrreversibleMigration end Then rename the old id column to integer_id, unset it as the primary key in favor of the new uuid column after renaming it to id. You need to start by running a similar migration, that will create a new uuid column. orm :active_record, primary_key_type: :uuid end How to migrate a table from integer to UUID primary key?Ĭhanging the primary key type in the table is not straightforward. If you want all your future models to use UUID for primary keys by default you need to add the following file:Ĭonfig/initializers/generators.rb Rails. timestamps end add_index :comments, :user_id end end Migration creating comments should look like that: class CreateComments < ActiveRecord :: Migration def change create_table :comments, id: :uuid do | t | t. For this sample case:Īpp/models/user.rb class User < ApplicationRecord has_many :comments endĪpp/models/comments.rb class Comment < ApplicationRecord belongs_to :user end Remember to set correct foreign key data type on relation models. You can now configure new tables to use UUID for their primary keys: class CreateUsers < ActiveRecord :: Migration def change create_table :users, id: :uuid do | t | t. To enable UUID in PostgreSQL, you need to create the following migration: class EnableUUID < ActiveRecord :: Migration def change enable_extension 'pgcrypto' end end ![]() Rails makes it just too easy to ship code like: class InvoicesController "b436517a-e294-4211-8312-8576933f2db1" Properly scoping access to resources in web apps with non-trivial business logic is hard.

![]() Though certain features that you may only use occasionally are more hidden and can only be accessed through the menu on the top side of the program's window. Although they are disabled by default, you can also add a tab for invitations and live chat.ĭue to this organization, everything you need is just a few clicks away without flooding you with a massive amount of information. On the other side of the screen, you’ll find another sidebar showing the history of messages, attachments, tasks, and appointments of your selected contact. This is surprising when we take into account the amount of customization the email client provides. It has an excellent organization throughout the four tabs: everything is straightforward and won’t take much time to understand how it works. On the left, you’ll find a sidebar where you can scroll between mail, calendar, tasks, and contacts tab. ![]() Overall, the eM Client interface is clean and straightforward, perfect for both the tech-savvy and for novices. Nevertheless, due to the number of features and simple interface, you may still want to use it on your Windows or Mac. PlatformsĮM Client is only available for desktop, meaning that you’ll need to use another email client on your mobile, which isn’t ideal. Fortunately, eM Client goes even further and also lets you configure S/MIME and PGP end-to-end encryption certificates in an easy way. eM Client uses TLS/SSL by default, protecting you from man-in-the-middle attacks, but that's still not enough since the email provider will still be able to read your email. ![]() To solve this, you need to add encryption to your emails. Companies too, such as ISPs and email providers, are also able to store your data along the way. This means that a hacker who intercepts the communication will be able to read everything. From when it leaves your account to when it arrives at its destination, your messages travel through various servers and most of the time, your data isn’t even encrypted. Still, the problem doesn’t end just by making sure you’re not clicking on dodgy links that will steal your information. ![]() Moreover, it will only show images from an email when you give permission or whitelist the sender. When it comes to security, eM Client filters spam and comes with anti-phishing protection. Having essentially three apps in one is great, but we also need to take into account the amount of privacy and security an email client provides. Nevertheless, there is a time where we need to concentrate on the task at hand and, fortunately, eM Client lets you snooze your inbox anytime you want. There’s also an integrated chat that lets you speak with anyone from Google Talk, Jabber or any other XMPP-based server. eM Client comes with a taskbar where you can create your to-do list which you’re able to customize by adding the level of importance and due date. However, eM Client shines the most when it comes to organization and productivity. On top of that, eM Client throws an email scheduler into the mix to make sure your emails are sent at the right time. Users can also create email templates, so you don’t need to write the same thing over and over again, as well as offering signature creation. It also offers a spellchecker to make sure you don't send that important email with any glaring errors. More than that, eM Client also helps save time while writing emails. Not only does eM Client give you an unlimited amount of email accounts associated with the application, but it also provides you with some neat features to make sure you don't lose yourself under a pile of emails such as a smart filter, thorough email rules, and folders to store your emails. When it comes to email management, there’s not much more you could ask for. With all the features it provides, you’ll be able to manage all your personal and professional tasks, direct message your friends, and more. FeaturesĮM Client is more than just an email client. Best of all, it does it all free of charge. Making eM Client an excellent product that not only will increase your productivity but secure your emails too. eM Client knows this and, since 2007, has been upgrading its services to answer its users' needs. Moreover, privacy and security have become a considerable concern to internet users lately, which means that email clients need to step up their game and start offering encryption tools so that the only people reading your messages are you and the recipient. We also need ways to filter our overflowing inbox, a calendar for our busy schedules, a handy task manager, and other productive tools to save us precious time. If there’s something that never goes out of fashion it's email, but with the advance of technology, it's no longer enough to simply send and receive emails. ![]() So how exactly does all this black magic actually work? It all comes down to a nifty physical phenomenon known as the Peltier Effect. “What that illustrates is that there’s a lot more to the sensation of temperature, or the subjective experience of temperature, than people realize,” Shames says, “and that’s really what we’re here to help people with.” Under the hood It does change temperature of your wrist while you wear it, but it’s not so much ‘tricking your senses’ as it is your brain and body naturally responding to temperature change.”Īs it turns out, changing the temperature of one part of your body can have a strong effect on how you feel overall. “So it doesn’t change your core temperature. “It’s kind of similar to cupping your hands around a hot mug of coffee in the winter after you’ve come in from being outside in the cold, or dipping your toes in the ocean on a hot summer day,” says Shames. Instead, it essentially tricks your body and brain into perceiving a slightly different temperature. It’s important to know that Wave doesn’t actually change how hot or cold your body is overall. “What it does is it heats and cools one spot on your body and helps you improve your comfort, without changing your core temp.” “It’s a product for people that are too hot or too cold, that offers thermal relief,” explains Embr Labs co-founder Sam Shames. The Waveĭeveloped by a team of MIT grads, the Wave is essentially a wearable heater and cooler that leverages quirks in human physiology to sort of “hack” how your body perceives temperature. I seriously keep a spare towel and a stick of deodorant on hand just in case I ever need to tie my shoes, unplug my monitor, or sneeze more than twice in a row.įor the past few days, however, I haven’t been as bothered by the oppressively high temperatures of the office - and it’s all thanks to a nifty new gadget called the Embr Wave. ![]() To be completely honest, I have no clue what the exact temperature is - but I do know that if you engage in any activity that’s more strenuous than sitting at your desk and typing, you almost immediately break into a sweat. OK, so obviously that’s a bit of an exaggeration. I know this because no matter what season it is or what the weather happens to be like outside, the office is almost always kept at a balmy 5,778 Kelvin. I don’t know who’s in charge of the thermostat at Digital Trends headquarters, but based on how hot they like to keep it here, I’ve concluded that this person was most likely born and raised on surface of the Sun. ![]() ![]() Some of the first were painted on bed sheets but now are painted and.

![]() ![]() this one tool can do it all but I find it easier to do the file rename with the gui tool ExifRenamer Im using macOS so you may need to translate this to your OS of choice. Here is the process I used to correct my images frustratingįor files that did not have and exif date I was lucky that the original file was saved in a date format like YYYY-MM-DD_HH-MM-SS.png Some of my files did not contain an exif original date so when copied to another drive the file modified date was updated moving the files to the most current date. simply updating the exif file modification time doesn’t completely fix the issue.ĭepending on the device the image was created on and the type of encoding some exif data may not always be present. The problems come when trying to correct this. in fact you can always revert to the original image on IOS. you don’t see this in IOS because when you edit an image it keeps the original image intact. nextcloud and every other tool out there uses this file modification date to show the files sorted by modification date not create date. if you edit a file the file modification is updated. every time you copy a file from one disk to another the file modification information is updated. When things can get funky is when you’re trying to manipulate your collection of images. When adding images to the nextcloud environment everything is dated and sorted by date correctly if it is a brand new picture taken at that time. This is more of my findings than a support question… I’m hoping this can help other people… The hotel "is projected to attract more economic development around the hotel, acting as a catalyst for future growth," developers wrote. "For large conventions at the Salt Palace, it is anticipated that many event visitors will stay at the proposed hotel" and use Salt Palace parking, designers wrote in planning documents. ![]() The Salt Palace currently has about 1,000 parking spaces, but the hotel will only add about 64 new parking stalls below the hotel, according to preliminary plans. The hotel will "anchor the southeast corner of the Salt Palace block to become a true urban complement of the downtown and a center of activity for the neighborhood surrounding the Salt Palace Convention Center," developers John Portman and Associates wrote in preliminary plans now under review in the city's planning department. The 725-room hotel with about 896,000 square feet of floor area, 62,000 square feet of meeting space, a nearly 26,000-square-foot ballroom, along with a restaurant, lobby bar and lounge, fitness and pool deck and an event terrace, will feature electronic displays and a glass and aluminum exterior, according to planning documents filed with Salt Lake City.Ĭonstruction is expected to begin later this year and slated to finish in 2022. John Portman and Associates, Salt Lake City Planning Department Here are some major projects coming soon to Salt Lake City's skyline:Īfter years of struggling to get the project up and running, city and county leaders are finally moving forward with what's slated to be a 28-story, 335-foot hotel on the southeast corner of the Salt Palace Convention Center, near 200 South and West Temple. "That's why we're starting to see this big boom," he said. Norris said it's thanks to Utah's steady economy and long-range planning that has set up Utah's capital to set its sights sky-high. "It's exciting to have a more cosmopolitan city," Valdemoros said, recalling how different Salt Lake City looked 19 years ago when she first came to Utah. To Salt Lake City Councilwoman Ana Valdemoros, who was recently selected to fill former Councilman Derek Kitchen's seat on the council representing downtown, the flux of new skyscrapers means an "exciting" time for Salt Lake City. One of the impacts of that is it does reduce the growth pressure in other parts of the city and, frankly, the region." "Downtown has the infrastructure and amenities in place that support it growing and getting bigger. In 2016, Salt Lake City leaders updated the downtown master plan after "extensive" public engagement to decide how downtown should grow, Norris said, and more skyscrapers are certainly a part of that plan. "It's been said that change isn't stressful, resistance to change is stressful." "There are always voices with concerns about that change, but if you look at the growth that is projected for Utah, inherent in that growth are changes in how we live and work," he said. "It's what makes great cities great cities."Īs the fight against density riles neighborhoods across the Wasatch Front, there's no place better suited than downtown Salt Lake City for high-rise offices, hotels and rentals, Brewer said. "Downtown is an appropriate place for that kind of densification," he said. "In the next 10 years, the skyline of Salt Lake City will continue to change as the downtown area densifies and as more people live downtown," he said.Īs the face of an organization dedicated to downtown vibrancy, Brewer said skyscrapers are a welcome addition to Salt Lake City's bustling business district. "This time next year, we'll have four or five cranes" operating in the heart of the city, said Dee Brewer, executive director of the Downtown Alliance.īrewer also hinted at some "preliminary conversations" with developers who have "other ambitious plans" for the area, though he also said it was too soon to give more details than that. ![]() That means that very soon, Salt Lake visitors and residents can expect a flurry of construction in the heart of Utah's capital to make way for the new skyscrapers. A 28-story high-rise of pure office space at 95 S.A 24-story tower that will become the city's first ever residential rental skyscraper at 151 S.A long-envisioned Salt Palace convention hotel on the northwest corner of 200 South and West Temple.Though it's not yet clear what will eventually become Salt Lake City's tallest skyscraper, there are several sky-high projects that have won a stamp of approval and are headed toward construction, including: ![]() There isn't a maximum building height in downtown's Central Business District, though there are certain heights that trigger design review requirements. It's an "urban legend" that buildings can't be taller than the church's office building, Norris said. Salt Lake City's current tallest building - the Wells Fargo Center - stands at 422 feet, just 2 feet taller than the Church Office Building of The Church of Jesus Christ of Latter-day Saints. Mint are beautiful pieces of art in fine silver. The foundation for the liquidity in the marketplace and the efficiency of pricing is largely credited to active players in the coin dealer network.Produced and sold for collectors, silver coins produced by the U.S. ![]() The level between is quite varied and the buying, selling, acquiring and liquidating is quite free and global due to the vast liquidity in both numismatic and bullion coin marketplace. For silver bullion coins, new sources come from government mints and their supply chain, while in numismatics, major supply can come from significant numismatic coin industry re-packaging suppliers or a significant collector's mass liquidation. Investors of bullion coins and collectors of numismatic silver coins are the foundation for economic demand in the silver coin market.Īt the other end of the market activity spectrum is the source of products, which is akin to manufacturing and distribution, and constitutes the foundation for supply. Each market has their own distinct end investor or collector. Silver coins can be categorized as either bullion/commodity value coins or as coins traded for their numismatic collectible value. The “Silver Coin Market” is comprised of two categories, each with three levels of interaction. 90% silver bags are anything but junk, and have traded anywhere from $10,000.00 to $30,000.00 in the recent past. Now, any silver coinage from any country worth its melt value is broadly referred to as junk silver. coins had little or no numismatic value as compared to the rising value of silver, and were therefore “JUNK!” and literally thrown in the coin counting hopper. In the mid 1970s, the term ''junk silver'' stuck as rare coin dealers found that many of their low-grade common-date U.S. He accurately and convincingly predicted the U.S.A closing its gold window and the personal financial utility of silver coins.

The silver coins most preferred for depository storage are the two most popular and liquid coins in the world, the U.S. For this reason, investors of silver coins should take into consideration where they will store their purchase, and is why investors purchasing larger quantities of silver tend to use a bank/depository storage facility. Most people could not carry $25,000 of silver coins without a wheelbarrow, whereas that amount of gold could fit in the palm of your hand.

Quite true, but paranoia and distrust of one's social "equals" can lead to a weird relationship with people below you on the caste ladder. Kevin Mack wrote: Keep in mind that In Cheliax the vast majority of people are paranoid and distrusting to begin with. (And of course, weirdness -> drama *heh*) If somebody is uniquely good at a socially-desirable function, yet is also considered repulsive for whatever reason, that's bound to create some kind of social-weirdness, whether on an individual or a group level. I know this may be one of those, "that's how it works/worked in the real world" arguments, but I think this is more a product of fundamental "human behavior" rather than any particular social/cultural practice. Giving tieflings greater, but not entirely unconstrained, social mobility could make such characters an interesting element of those sorts of plots. Heck, even in the outlying/rebellious states of former-Cheliax, there's always some faction that supports "rejoining the motherland", or some traitor who seeks glory/wealth/revenge by betraying the rebels to their "imperial masters". Tieflings are described/perceived as similar ambassadors between humans/mortals and devils/fiends/infernals, so in a land where that function is necessary or valued, the people doing the job would gain some kind of perfunctory authority or value. Half-elves at least are described as filling roles as liaisons and ambassadors between and among human & elven cultures which can gain them some level of acceptance and prestige (however begrudging or patronizing that might be). It's as though they were a group born to be used as a tool - for wielding arcane magic, for creating a bridge between worlds, even for showing loyalty (however false) to the Thrune-dictated party-line. It's because tieflings are closer to the corridors of power, either by birth, family/House, or association that I think they would have a weird place in society. ![]() Certainly there's a good deal of social space between liking tieflings & and creating a tiefling "untouchable" caste. This is much larger than its southern cousin the Floridian black bear ( Ursus americanus floridanus) which weighs 300 pounds on average. For example, a male polar bear ( Ursus maritimus) typically weighs between 770 and 1,540 pounds. Bergmann’s Rule states that animal species in colder climates will be larger than related species in warmer climates. In the animal kingdom, different evolutionary trends relate body size to ecology. The average atmospheric temperature in the winter is between -22 and -31-degrees Fahrenheit (-30 to -35-degrees Celsius). The temperature in the Arctic circle is influenced primarily by the surrounding sea water which is 28.8-degrees Fahrenheit (-2-degrees Celsius) before it freezes. ![]() Polar bears inhabit the arctic circle including territories of Canada, Greenland, Norway, Russia, and the United States in parts of Alaska.

A polar bear is insulated by fur and fatty tissue This is similar to how snow appears white despite having no pigment. In polar bears, the guard hairs are translucent and appear white because of how they reflect light. The outer layer of fur is called guard hair. Interestingly, a polar bear’s famous white fur has no white pigment. Polar bears are not only the largest bears in the world, but they are also the largest carnivores on land! These magnificent creatures are admired for their beautiful white coats and their particularly adorable little cubs. |
