Needs some configuring, but should run well. If it comes up again will use this preelcapitan option. To resolve it, I scrapped the Steam copy completely and went with my Winebottler approach and it worked. I know Wineskin (which I make myself since WineBottler isn't as good and basically dead. A player recently had an issue with the Steam version of FG on their Mac where it was not loading. Its not free like normal Wine (which is compile yourself and all command line) or Wineskin or WineBottler. It runs some things great, some things ok, or poorly, and some things it won't run at all. it uses "Wine" to run things, same as Wine, Wineskin, WineBottler, etc. its sort of like an emulator, but its not really.

If you kill your opponent during the duel, there will not be any bounty or aggression because of it. It is possible for either you or your combatant to kill the other accidentally if enough damage is dealt to a weakened foe. If you lost, the NPC will allow you to live and continue on with their business.ĭuels aren't without risk though. If you won the duel, you have the option of either executing your downed target by attacking them again (WILL kill essentials), or allowing them to live by sheathing your weapons. When either the player character or the enemy drop below 20% health, they will go unconscious. Their allies will not jump in to help them, nor will their factions declare you an enemy. If the NPC accepts the challenge (read: negative relationship, and not currently following you), you enter combat with them. Don't worry about that too much though because challenging someone to a duel hurts your relationship, naturally. In order for the targeted NPC to accept the challenge, they must have a negative relationship with the player. When all 3 words of the shout are used, the NPC in the player's crosshair is challenged to fair combat by the player. This mod adds (and unlocks automatically) a single shout to the player called Challenge. Our closest alternative is to commit murder and then reload a previous save. According to him, challenges to fair combat are a custom of Skyrim, to be respected even from a legal standpoint.ĭespite this, we are unable to issue our own challenges to NPCs.

I hope that future versions of the GoPro Player + Reelsteady app will restore this option. Turning off world lock lets the video point wherever the lens is pointed, and it can save a lot of time for editing videos where you are constantly changing direction, such as on a roller coaster. One disadvantage of the new app is that when you’re reframing GoPro MAX videos, you cannot turn off the World Lock option (forward facing stabilization). This means you can use rectilinear on some keyframes and transition to fisheye on other keyframes. Now, you can adjust the lens correction for every keyframe. Previously, there was only one projection mode for reframed GoPro MAX videos, which was somewhere between rectilinear and fisheye. On the new app, the video is not as contrasty, and you can see better shadow detail on my clothes, and better highlight detail in the clouds. Although Reelsteady cannot be applied to GoPro MAX videos (as of the date of this post), the new app does improve the dynamic range of the GoPro MAX, as shown in the sample video below. Please note that the stabilization will perform better when the projection is set to rectilinear. Tip: for a rectilinear video, adjust Lens Correction to 50. With the new app, you can control the distortion to make it look more like a fisheye video or a rectilinear video. On Reelsteady Go 1.0, it would apply a rectlinear projection to the stabilized. With Player + Reelsteady, you can now batch export several videos with Reelsteady stabilization. With the standalone Reelsteady Go, you had to apply Reelsteady on each video, one by one. With the new GoPro Player + Reelsteady, you’ll see the stabilization in just a few seconds. It takes more than 5 minutes to render 1 minute of video. The standalone Reelsteady Go is extremely slow. Please note that Reelsteady works best with unstabilized GoPro footage shot in 4:3 aspect ratio. Just click on the Reelsteady menu and login with your Reelsteady credentials. Reelsteady isn’t free - you’ll need to pay $99.99 for it but if you already have Reelsteady Go, you can upgrade for free. Rather, it analyzes a few seconds of footage at the same time to find the smoothest stabilization.īecause of these differences, Reelsteady can produce much more steady video than Hypersmooth or any other stabilization software I’ve seen. Second, Reelsteady doesn’t just examine the gyro data from a single frame. Where there is not much movement, it will use a wider field of view. In scenes where there is more movement, it will crop more tightly for better stabilization. Compared to the Hypersmooth stabilization in GoPros, Reelsteady has two major differences: first, its cropping is variable. The biggest difference is the option to add Reelsteady 2.0, a stabilization software for GoPro Hero (note: as of April 11, 2022, Reelsteady does not work on GoPro MAX). Reelsteady option for Hero cameras (even Hypersmooth was enabled).Here are the differences between the GoPro Player 1.0, the standalone Reelsteady Go, and the new combined GoPro Player + Reelsteady. With this update, GoPro decided to integrate GoPro Player with Reelsteady Go. GoPro Player is the app for stitching and reframing GoPro MAX (reviewed here). Here are 7 differences between the old app and the new app. GoPro updated its GoPro Player app to combine it with Reelsteady Go 2.0, and to add other new features.

The chef stumps for food carts, secret spots, and stress relief in The City of Roses. It's a favorite childhood food of Lamagna's, given a cheffy makeover in a dish called mangga at bagoong alamang: It arrives at the table in a small boat carved out of raw green mango and is covered with a shower of edible flower petals. And then there's the electrifying, elemental funk that ripples through the bagoong alamang, a condiment of fermented shrimp paste spiked with garlic, fish sauce, and palm sugar. It fully embraces its sour notes, with punches of tamarind knitted together by tomato, fish stock and fish sauce, onions, and garlic. The translucent broth that forms the base of his sinigang at Magna Kusina, Lamagna's Portland, Oregon, restaurant, has the elegant gleam of consommé but is anything but subtle in flavor. Restaurants may no longer look the same, but with this class of chefs at the helm, I am excited to see-and eat-what the future holds.Ĭarlo Lamagna approaches Filipino food like a Grand Prix race car driver: He drives with extreme precision and finesse, but he isn't afraid to press on the gas. There's the scrappy chef in Portland, Oregon, who is making America fall in love with the robust and complex flavors of Filipino food and building a gathering space for his community, and the chef in Ann Arbor, Michigan, who merges Midwestern produce with centuries-old Korean recipes while also compensating her staff well above market standards and providing a slew of benefits.įrom coast to coast, the 2021 class of Best New Chefs is reinventing what it means to lead in the kitchen while cooking the food that matters to them most. There's the chef in Austin who is running an ambitious in-house masa program while prioritizing the mental health of his team, and the pastry chef in Washington, D.C., who is baking whimsical desserts that center the flavors of her Dominican heritage while launching bake sales that help combat racism. This year's class of Best New Chefs exemplifies this approach to leadership.

So, for me, the idea of something that automagically creates some kind of balance between the desktop dump and folder-em-and-forget-em holds a lot of appeal. (I do snap them into an orderly grid - I'm not a chaos monster.) To make sure you can see that system, Apple is also adding Desktop Stacks.Ĭonfession: I'm one of those people who dumps almost everything onto the desktop and then, when it feels too cluttered, drags it all into Downloads, and leaves it buried there until system cleaning or failure requires or ordains its removal. It just makes the whole system feel so much more fluid and alive. If we can have sticker apps, why can't we have wallpaper apps, right? Actually, I hope Apple lets designers and developers make third-party dynamic wallpapers - for both macOS and iOS. The effect works so well, I hope Apple adds more Dynamic Wallpapers to the mix. Often, they've been redrawn to replace outlines with solid forms and details with knockouts. Glyphs, or the monochrome icons used throughout interfaces, have also been adjusted so that they maintain weight legibility on dark backgrounds. Basically, gray background elements take the place of white so that the contrast stays high, even in lower opacity levels. Vibrancy, which is what Apple calls the bright, saturation boosted, translucent effect applied to things like app sidebars, is also optimized in Dark Mode to maintain legibility. (If you hate the idea of tinting, you can pick the graphite accent "color", which forces no tinting at all.) It's a dynamic process that updates as you move windows around, so all the elements on your screen always feel part of a cohesive whole. Then, it subtly tints the window - and controls because of their slight translucency - based on the average colors, and mixes that with a base gray, so that the color temperature of the window matches the rest of the environment and your wallpaper. In order to prevent clashes, the system samples what's behind a window, including the system wallpaper. (Though Dark Mode gets a rim stroke to go along with a stronger rim shader to keep it looking nice and crisp.)Īlso, Dark Mode isn't just dark-as-in-desaturated. Windows, on the other hand, to maintain a consistent depth effect, have drop shadows in Dark Mode just like they do in Light. Some is not so obvious: The effect that indicates buttons are grouped together, instead of looking recessed, looks backlit. Some of what Apple has done with Dark Mode is obvious: When you click a button, instead of it getting darker, it gets brighter. It might seem like a small thing, but being able to highlight your interfaces with your favorite colors doesn't just make controls pop, it makes you pop. Joining the venerable blue and graphite are red, orange, yellow, green, purple, and pink. To coincide with Dark Mode, Apple has added new accent colors as well, and they work for both Dark and Light. I need my light! So, the ability to switch easily makes both modes better. I particularly like that aspect because, while I love Dark Mode for some pro apps and late night use, I find it a tad overbearing and even gloomy if I sit in it all day. My eyes and my moon need light! This way, whenever I have the slightest urge to switch, I just switch and go on about my business. While I love Dark Mode for some pro apps and late night use, I find it a tad overbearing and even gloomy if I sit in it all day. That the modes are so easy to switch between is especially great. That way, apps look cohesive no matter which mode you're in. So, for example, a lighter sky blue banner for Light Mode but a navy blue banner for Dark Mode.

Yeah, meanwhile, he is still waiting for the information to be authorized so he can swindle you. So, the banking entity puts the transaction on hold, to keep the criminal in place. Those 3-5 seconds that it usually takes for a normal card's transaction, to take place are all that it takes for the banking entity to know that it is an unauthorized transaction and where that criminal is located. When the criminal swipes the cloned card, keyed in your stolen PIN, than he reads on the little display screen "waiting for cashier", and the cashier presses the button. And, the account that the debit card is connected to have been made inactive, by its owner. If the criminal use the debit card outside of the restrictions the banking entity, again, will know in real time and can take action.įor example, if a criminal with a clone debit card tries to make a purchase at a retailer. Much in the same way, if the criminal tries to use the stolen debit card and the account has been restricted. The banking entity being coordinated with the account owner's set up will know that it is an unauthorized transaction request, in real time, and can take action. If a criminal tries to use (Lets say) a stolen debit card and the account, is inactive. This will take all the guesswork out of the is it you or an unauthorized transaction. Because, all that the banking entity will have to do is monitor for any transactions that go against the account owner set up. This will greatly aid the banking entities in protecting their accounts. They are telling the banking entities their intentions, how long, where, how much, etc. And, when they make their account active, with restrictions. For instance, when the account owners make their accounts inactive, they are also telling the banking entities, essentially that they are not intending to use their accounts. Second, this will give the account owners and the banking entities a covert way to coordinate the accounts' outgoing transactions. Because, an account with its outgoing transactions inactive are as secure as a safe deposit box. They account will be secure against a criminal using one of their lost, clone, or stolen checks and/or debit/credit cards. These actions will add security in two (2) ways.įirst, when the account owners make their accounts inactive. The restriction can be how long they are going to use their accounts Where they are going to use their accounts How much they are going to spend from their accounts, etc. And, when active it can be with restrictions. Than make active when the need or want to use their accounts. This will allow the account's owners to be able to set up their accounts' outgoing transactions, inactive (meaning to freeze the account) when they don't need to use their accounts. Via, an assigned secure connection such as a website, and/or phone/text service. Preferably, by the account owners using a direct link to the banking entities' mainframe or computer. The Geym Cheynjer is basically when the banking entities allow the account owners the ability to control their accounts' outgoing transactions. In September 1967, Lorber announced his plan to make Boston, in his own words, "a target city for the development of new artists from one geographical location." Lorber announced his project in a Newsweek magazine article in January 1968, in which he touted new bands which were emblematic of the movement, including Ultimate Spinach, Beacon Street Union and Orpheus. There is also a thought that the band name was in accord with other colorful psychedelic band names during that era and got the band attention. When I was done, I looked at myself and said 'Whoa! I am ultimate spinach. I grabbed a green one and started drawing all these psychedelic designs on my face. I had a bunch of colored markers I used to draw with. I started looking at myself in the mirror and my face was doing funny things. Bruce-Douglas says that he named the band based on experiences in an acid trip: "One day, in 1967, I was in my room, tripping on some really pure LSD. The name of the band was changed to Ultimate Spinach when they signed with Boston impresario Alan Lorber (Lorber produced all three of their albums). As Underground Cinema, the group served as house band in a club called the Unicorn and recorded demos which later appeared on New England Teen Scene: Unreleased! 1965-1968, in 1966. The band originated as a group called the Underground Cinema, with a line-up consisting of Ian Bruce-Douglas as a multi-instrumentalist, Barbara Hudson as vocalist, Keith Lahtenein on drums, Geoff Winthrop on rhythm guitar, and Richard Nese on bass guitar.

Other chlorophyll a molecules, chlorophyll b, and the carotenoids (carotenes and xanthophylls) capture light energy and send it to chlorophyll a at the reaction center. A molecule of chlorophyll a is located at the reaction center of the photo systems. Chlorophyll a is the primary photosynthetic pigment in plants. Chlorophylls contain oxygen and nitrogen and are bound more tightly to the paper than the other pigments. Xanthophyll is found further from the solvent font because it is less soluble in the solvent and has been slowed down by hydrogen bonding to the cellulose. Another pigment, xanthophyll, differs from carotene in that it contains oxygen. Beta carotene, the most abundant carotene in plants, is carried along near the solvent front because it is very soluble in the solvent being used and because it forms no hydrogen bonds with the cellulose in paper. Be sure to keep the beaker tightly covered except when you are using it because the solvent is very volatile and produces fumes you should not breathe (see Figure A2). Chromatography setup ■ Learning Objectives In the following activity, you will separate plant pigments in chloroplasts using an organic solvent, such as a mixture of ether and acetone. Such is the case with pigment molecules inside chloroplasts. Chromatogram In black ink, what appears to be a single color is actually a material composed of many different pigments-green, blue, red, and lavender. In the chromatogram shown in Figure A1, the solvent for the ink mixture is water. The rate of migration occurs at different rates because of differences in solubility of pigment molecules in the solvent, the molecular mass of solvent molecules, and hydrogen bonding of solvent molecules with the paper. The molecules migrate up the paper due to capillary action, which in turn occurs as a result of the attraction of solvent molecules to the paper and attraction of solvent molecules to one another. The pigments are dissolved in a solvent that carries them up the paper. Exercise A: Plant Pigment Chromatography Paper chromatography is a technique used to separate a pigment mixture into its component molecules. Critical to the process is chlorophyll, the primary photosynthetic pigment in chloroplasts. Plant Pigments and Photosynthesis Introduction In photosynthesis, plant cells convert light energy into chemical energy that is stored in sugars and other organic compounds. |
