Although programs may be compiled via an IDE or the command line, in fact, they are simply translated into IL, not machine code. Explain An Intermediate Language?Īssemblies are made up of IL code modules and the metadata that describes them. What Are Assembly Attributes?Īttributes are declarative tags in code that insert additional metadata into an assembly. Processors can broadly be divided into the categories of: CISC, RISC, hybrid, and special purpose. Some processors have different instructions for loading registers and storing to memory, while other processors have a single instruction with flexible addressing modes. The source and destination locations are determined by the addressing modes, and can be registers or memory. Not all condition codes available for a processor will be implemented for every conditional instruction.ĭata movement instructions move data from one location to another. Some processors have a few additional data related conditional instructions, and some processors make every instruction conditional. Typical conditional instructions include: conditional branches, conditional jumps, and conditional subroutine calls. What Is Assembly Condition Codes?Ĭondition codes are the list of possible conditions that can be tested during conditional instructions.

1/7/2024 0 Comments Batman arkham cityHarley Quinn's Revenge is a post-launch DLC epilogue. Batman: Arkham City Watcher in the Wings side mission guide.Batman: Arkham City Identity Theft side mission guide.Batman: Arkham City Shot in the Dark side mission guide.Make sure to check out the rest of our Batman: Arkham City guides! Then it heads upwards again, past circling news choppers and roving blimps and towards the lofty Art Nouveau ironwork of Wonder Tower, where mysterious forces are battling for the soul of this depraved metropolis.Cameras are indicated on the map for each area, they're easy to spot once you're near them so we haven't included images of each. The narrative drills down under the streets, past abandoned railway terminals and fragmented tenements and into a strange, clockwork fantasyland based on a 19th-century World's Fair. It's a funny-books spin on Chinatown, at heart. If the first game hinged on a calculated deconstruction of Bruce Wayne's psyche, the sequel is more concerned with excavating the past of Gotham itself - and plotting its possible future. Just as the first adventure played up Joker's skills as a deadly kind of game show host, Penguin's been transformed into a grubby east-end thug with a beer bottle ground into his face in place of a monocle, while Mr Freeze is otherworldly and tragic in his refrigerated spacesuit and Hugo Strange is hulking yet somehow frail: hypnotic in voice, but measured and occasionally even sympathetic in person. The very best of these inmates have been given the Rocksteady once-over, emerging with unlikely kinks in their iconic elements. Given the kind of inmates we're dealing with here, it's suitably gratuitous. Arkham City is positively exhaustive with its cast, roping in an astonishing range of murderous megastars for the main campaign and then flinging out even more as you start to explore the side-quests. Rocksteady makes greedy use of the fact that Batman hasn't only got the best backstory, he's got the best enemies too. Into this landscape of uneasy truces and shifting alliances comes Batman, and the story that unfolds is a race-tuned comic-book narrative in the style of Hush or The Long Halloween: a story built of short, punchy escapades, where any plot-twist is excusable as long as it lands you with a neat gadget or sends you pinwheeling from one supervillain cameo to the next. Now, under the all-seeing eyes of Dr Hugo Strange, these inmates have started to form gangs and carve up the territory. Surrounded by guard towers, spotlights and barbed wire, psychopaths have taken back everything from the Bowery to Crime Alley - where you-know-what happened - and the old GCPD building. The set-up is simple: the former warden of Arkham Asylum has become Gotham's mayor, and he's turned the city's slums into an expanded loony bin. The kind of scale, in fact, that only video games can deliver, creating courtyards, avenues and entire neighbourhoods mired in crime and gothic mystery. It's a Batman simulator as much as a Batman game. Arkham City just makes it all a little less awkward. We've been Batman for years, if only somebody would notice. I must be a creature of the night! You said it, Bruce. Promising to avenge your parents' deaths, even though they were still alive and well and sat in the next room, arguing about why the Morris Minor wouldn't start that morning. Daydreaming of dangling cyclists over the ledges of skyscrapers when they rode their freakin' bikes on the sidewalk. Pretending a series of bedrooms and attics were subterranean strongholds. And partly because, if you're like me, you've secretly been Batman since primary school anyway. In Arkham City, you become Batman.Īnd it's an easy role to play, partly because Arkham Asylum already laid out such an excellent framework, delivering not just the power of the Dark Knight but also his cunning and his tightly controlled rage. Animations, traversal mechanics, takedowns: they're all building towards the same thing. It's a role-playing game in the most literal sense of the phrase, a game in which you're encouraged to give in to the fantasy, and to see what life is like when it's composed of rooftop brawls and zip-line getaways. Not just because you gain XP, engage in a little light levelling and are free to sharpen your combat skills one upgrade at a time. It's a role-playing game, when you get down to it. 1/6/2024 0 Comments Edu kids incIf this sounds like a good fit, we want to meet you! Please submit your application today.

We determined that HoxLuSfo.exe was spawned by sihost.exe, a background process that launches and maintains the Windows action and notification centers.įigure 1: PowerShell command identified by Rapid7's MDR on infected assets Specifically, the alert detected a PowerShell command spawned by a suspicious executable named HoxLuSfo.exe. The MDR SOC first became aware of this malware campaign upon analysis of "UAC Bypass - Disk Cleanup Utility" and "Suspicious Process - TaskKill Multiple Times" alerts (authored by Rapid7's TIDE team) within Rapid7's InsightIDR platform.Īs the "UAC Bypass - Disk Cleanup Utility" name implies, the alert identified a possible UAC bypass using the Disk Cleanup utility due to a vulnerability in some versions of Windows 10 that allows a native scheduled task to execute arbitrary code by modifying the content of an environment variable. The malware is classified as a stealer, which intends to steal sensitive data from an infected asset (such as browser credentials and cryptocurrency), prevent browser updates, and allow for arbitrary command execution. Recently, we identified a malware campaign whose payload installs itself as a Windows application after delivery via a browser ad service and bypasses User Account Control (UAC) by abusing a Windows environment variable and a native scheduled task to ensure it persistently executes with elevated privileges. Rapid7's Managed Detection and Response (MDR) team leverages specialized toolsets, malware analysis, tradecraft, and collaboration with our colleagues on the Threat Intelligence and Detection Engineering (TIDE) team to detect and remediate threats.

Another reason is the lack of "always one selected value", popular among developers but a drag on RAM and CPU. This may be attributed to fewer objects and expressions visible and calculating on a sheet at one time.We have observed generally faster calculation time in Qlik Sense compared to QlikView, allowing for acceptable response time with even larger data models.Generally better calculation performance and RAM footprint. All of your applications will have a consistent appearance, navigation, and interactivity - not based on the skills or preferences of the developer.Responsive design means that there do not have to be separate desktop and mobile sheets or intended designs.This also means more room for visualizations! These are obsolete due to the selection bar and Selection Tool. There is no need to put the same set of objects on every page: lots of filters, Current Selections, Search Object, a background image.We still use template applications for UI, but they are much simpler, with out sample layouts (currently), sample report builder interfaces, etc.The good news is that self-service has made these obsolete.īuilt-in functionality replaces some things developers used to have to manually do. Qlik Sense is not as good at creating generic reporting interfaces like people did in QlikView, like report builders, and you're unlikely to see apps with a bunch of filters and one table that users are exporting to Excel.No more hidden tabs or "subtabs" (without extensions): analysis and detail may sometimes be on different sheets. The grid function and lack of object layering with show/hide make it difficult to design sheets with built-in workflows. That simple content may be spread out over more sheets than were required in QlikView, however.(Note: we are not saying to skip the design time, just that you should focus it on the main business value and not each user's personal whims.) This often amounts to less UI content in the base application that is published, while the base content in QlikView apps was all most users would ever get. Users will be creating their own content through self-service, so the UI design can focus on addressing only the most important business value and most commonly asked questions by the application audience.Less time is needed to build the front end in a Qlik Sense project compared to QlikView projects. It's not practical or efficient to build a whole data model with it or to use in QVD-generating applications.īuild less and more simply, enable more. The Data Manager will not realistically be used by developers in its current state.A difference is that the application files themselves will not be among those files, instead being administered by the server and accessed through your browser. BI developers will likely still need some level of access to the folder structure of the development environment (not necessarily UAT or Prod) to delete QVDs, modify included files, or create folders to organize QVDs.QVDs are still recommended for reducing impact on source systems, incremental extracts, and data re-use.We still use and recommend template apps for QVD generators and spending a bit of time coming up with an overall structure for organizing QVDs, even though folder connections are now managed more smartly, through Data Connections.The same amount of time should be budgeted for data modeling in Qlik Sense projects as on QlikView projects. Very little has changed with loading data and the data model. What you can practically expect in Qlik Sense applications to best leverage the product, compared to QlikView Loading data/data model My goal is not to try to make people forget about QlikView and move on to Qlik Sense, but to help those accustomed to QlikView pilot Qlik Sense in a way that is informed by the strengths and differences in the platforms. In this final post in the series, I will describe how my approach to application development has changed as I have gotten to know Qlik Sense better. In part 2, I described the inverse: what QlikView still does better than Qlik Sense. Part 1 of this series describes what Qlik Sense does better than QlikView, from the perspective of an experienced QlikView application developer. If you plan on drying your cotton clothes, look for sizes that are slightly too big to accommodate shrinkage. Remember that cotton clothing will shrink a small amount the first time you wash and dry the fabric.In one store you may be a medium, but in another you may be a large. Look at how the clothes you try on make your body look, and be flexible when it comes to size.No matter how cool the style is, if it doesn't fit you, do not wear it. The fit is the most important aspect of any article of clothing.Individual people, however, usually have bodies that are a bit different. Clothing companies use average measurements to determine sizing and fit to try to cater to many people. Know that your fit is more than just your size. If this is the image you want to project, and you’re not going to a formal event or an office, that’s fine. Hipster clothes might make you look skinny. Hip hop clothes, for example, tend to be a lot baggier, and can make a guy look bottom-heavy.Just be conscious about how your clothes make your body look, and think about how to compromise good proportion with fashion statements. It’s OK to play with these proportions a bit, depending on the occasion and your social group.Take an honest look at how your body matches up to this ideal, and look for clothes that hide and accentuate the right parts. The ideal masculine proportion is tall, wider at the shoulders and narrower at the hips.Look at the lines and shapes your clothes make on your body, and consider how they relate to optimal proportions. Think of dressing as creating an optical illusion.Clothes can make a big difference in how your body looks, and can give the illusion that you are taller or thinner than you are. You don’t need to have an ideal body to look good in what you’re wearing. Just exercise a little restraint to make sure you don’t go overboard. If you have a dramatic personality that likes to make a statement, it would make sense to have that reflected in your clothes.If you have a casual, quiet, no-nonsense personality, it’s perfectly acceptable to have a simple wardrobe with just a few, well made, basic items.You shouldn’t have to worry just because you don’t have a classic button-down oxford shirt in your closet. Dressing well also doesn’t mean that you have to follow a lot of rules for tailoring and "what every well-dressed man should have".Wanting to dress well does not mean that you suddenly have to pay a whole lot of attention to fashion or be aware of all the trends.Just make sure that you’re not wildly inappropriate or projecting an image that doesn’t do you justice. X Expert Source Tavia SharpĬertified Image Consultant Expert Interview. You don’t have to force yourself to be anything you’re not, and it’s very important that your clothes accentuate who you really are. Dressing up will make you look more involved, approachable and confident.Ĭonsider your personality when picking your clothes. Show that you respect the event, and are involved in the moment. For formal occasions, don’t try to get away with being underdressed. You can wear a t-shirt of a band you like, or a little bit of camo if that reflects your interests, but always work it into your outfit so it looks like it’s in context. Choose a darker, classy color for increased versatility grey, dark blue, and black are excellent choices.
1/6/2024 0 Comments Hp photosmart 6510 inkUnfortunately, HP seems to have abandoned the notion that users will ever scan anything thicker than a letter: None of the Photosmart units we’ve tested have a telescoping lid to facilitate the scanning of pages from magazines or books. You don't get an automatic document feeder here, but you can find an ADF on a slightly higher-priced cousin, the Photosmart 7510. The output tray holds 50 sheets, and the MFP offers automatic duplexing (two-sided printing). The 80-page paper cassette has an integrated 20-sheet photo tray. Paper-handling features for the Photosmart 6510 are fine for low-volume printing and the occasional scan. The Photosmart 6510 supports HP’s Web-based apps and remote Web printing, as well as local printing via Wi-Fi from Android and iOS devices. It also allows you to scan from the control panel to a PC or a Mac, even if you're using Wi-Fi some competing models require a USB connection for this function. HP's bundled software for the Photosmart 6510 is simple to use and supports all of the unit's capabilities, including scanning and copying. The MFP does support USB and Wi-Fi, though, and the installation routine is concise. Connectivity falls a bit short: You’ll find only SD and Memory Stick card slots behind a front panel, and the machine has no USB/PictBridge port-an unusual omission. The screen is large enough to read and tap easily, too, making the unit as a whole very easy to use. The Photosmart 6510's good looks are partly due to its 3.45-inch touchscreen control panel. But it’s also a good printer, with first-rate output quality and better-than-average print speeds, though ink costs are just average. The first thing you'll notice about the $169 HP Photosmart 6510 e-All-in-One color inkjet multifunction printer is that it looks better than the competition. 1/5/2024 0 Comments Amethyst birthstoneThe geodes can be small enough to hold in the palm of your hand, or enormous sections of lava tubes that can be several meters long and weigh several tons. Data from the United States Geological Survey. An amazing amount of amethyst is being produced. Much of this production is sold in the form of geodes, crystal plates, crystals, and tumbled stones. The United States Geological Survey estimated the world’s commercial amethyst production between 20. Some of the amethyst in the Spanish crown jewels may be from this deposit, brought back to Spain by Spanish explorers. The deposit was also known by Native Americans because a few amethyst arrowheads have been found nearby. The mine is well known for producing amethyst with a reddish purple color. Today, the only commercially run amethyst mine in the United States is the Four Peaks Mine in Arizona. Much of it has been as a byproduct of other mining operations. Other productive amethyst deposits are located in Canada, France, India, Madagascar, Mexico, Morocco, Myanmar, Namibia, Russia, South Africa, Sri Lanka, Tanzania, and the United States.Īmethyst has been produced at many locations in the United States. This is a 10.5 x 8.5 millimeter gem, weighing about 3.15 carats. Four Peaks is the most important amethyst mine in the United States and is famous for producing amethyst with a reddish-purple color. Faceting, cabbing and ornamental grade amethyst can be found in all of these locations however, the amount is usually insufficient to support an ongoing mining operation.Īrizona Amethyst: A beautiful reddish-purple amethyst from the Four Peaks Mine, Maricopa County, Arizona. Small amounts of amethyst are found at many locations throughout the world in igneous, metamorphic, and sedimentary rocks. The name "amethyst" is an incorrect varietal name when used as an adjective for chalcedony. Purple chalcedony and lilac chalcedony, are acceptable names for this material. These materials also have a difference in refractive index. There is where you can observe the luster. If you use a hand lens or a microscope to examine the facet junctions on a faceted stone or the boundary between the flat base of a cabochon and its domed sides, you can usually find at least one tiny conchoidal fracture. Quartz has a vitreous luster on conchoidal fracture faces, while chalcedony has a dull luster on conchoidal fracture faces. The name chalcedony is used for microcrystalline quartz - quartz that is in crystals so small that they cannot be seen without the aid of a microscope.įortunately, it is easy to tell the difference between quartz and chalcedony. Why are those names improper? They are improper because purple quartz (amethyst) and chalcedony are two different gemological materials. It is often improperly called "amethyst" or "amethyst chalcedony." Purple Chalcedony: Chalcedony can occur in a wide range of purple colors. Enormous deposits of amethyst in South America and Africa provide enough amethyst to keep the price low. That makes it durable enough for use in rings, bracelets, earrings, pendants, and any type of jewelry. It is used to produce faceted stones, cabochons, beads, tumbled stones, and many other items for jewelry and ornamental use.Īmethyst has a Mohs hardness of 7 and does not break by cleavage. It is the purple color variety of quartz that has been used in personal adornment for over 2000 years.Īmethyst is the birthstone of February and an important New Age gem. Amethyst is the world's most popular purple gem. 1/5/2024 0 Comments Raindrop cake with flowersWhere can you try Harajuku gyoza’s Raindrop cake? It doesn’t even pop - it just sort of instantly dissolves. Yes, it is squishy, yes, it is jiggly, but the second it enters your mouth, it melts into water. Is it like eating a raindrop in your mouth? Also, it looks exactly like a breast implant. It felt like a snack a Martian would eat. But the Raindrop Cake itselfI’ve never tasted something that is inherently, well, tasteless. They deserve to be sprinkled on all the pancakes in the world. The brown sugar syrup and soybean flour it’s served with are SO delicious. What do you think about the Raindrop cake? Matched with the nutty and sweet toppings, this cooling cake has an interesting combination of tastes and textures. The gelatin allows the refreshing “raindrop” to melt in your mouth, for a light, cooling affect. The trick is in the gelatinous substance called agar, which is made from seaweed. How to Make a Raindrop Cake Look Like a Work of Art. Wong told Slate that eating the Raindrop Cake ‘tastes like eating a giant raindrop.’ The cake ‘is very mild and very much about the delicate texture the melts in your mouth. Since the cake itself has almost no taste, it’s served alongside roasted soybean flour (kinako) and a sugary syrup called kuromitsu. (Think more airy and cool than rich and sweet.) But it’s the texture that really makes this dessert unique: It melts in your mouth, like a drop of water. So what does Raindrop Cake taste like, exactly? Though the cake itself didn’t have much taste, the syrup and the soy powder give the raindrop a nutty flavor. 1/5/2024 0 Comments Netspot review pcmagNeed more help? Check out our guide to Wi-Fi extender placement. You need to find somewhere that's close enough to the router to grab a strong signal to rebroadcast, but far enough away to extend the network's range to where it's needed. Placement Is Everything: Both wireless routers and Wi-Fi extenders use radio waves to share data back and forth with your internet connection.If you have an older wireless-N router, then a matching extender will do the job just fine. But that's a problem only if your router is offering better speeds. The older 802.11n standard is slower and often is limited to one band, which will create a bottleneck in your Wi-Fi coverage, slowing down all of your browsing and streaming. If your wireless router uses the current 802.11ac standard, you’ll want to be sure your extender does, too. Match Wi-Fi Standards: While you may not pay much attention to which wireless standard your router uses, it will definitely have an impact on how helpful your extender is.Plug-in models, on the other hand, will often be less expensive and more convenient to install. These larger devices don't have the same size and weight limitations of plug-in units, allowing for better antenna placement and better internal hardware. Some of the best Wi-Fi extenders use larger designs that sit on a desk or shelf, more like a traditional router. Plug-In or Desktop? While most signal boosters use small plug-in designs that connect directly to a wall outlet, they aren't the only option.The attractively low price also brings extremely poor performance. And watch out for cheap discount range extenders, like the one in our Super Boost Wireless-N Wi-Fi Repeater review. Newer signal boosting devices have support for the latest wireless standards and offering technologies like beam-forming and Mu-MIMO for enhanced performance will often cost more, but even the best extenders can be had for less than $200. How Much Should a Wi-Fi Extender Cost? The cheapest Wi-Fi repeaters will often sell for less than $50, and our current budget pick sells for half that.How to choose the best Wi-Fi extender for you If you have multiple rooms with spotty coverage or a far end of the house that your router just can’t reach, or want to extend your coverage out to the backyard or garage, then a mesh kit is the better choice. However, if you have large portions of your home or property that don’t get adequate Wi-Fi, you may need to step up to one of the best mesh Wi-Fi systems, which use multiple devices to create a larger shared network. Wi-Fi extenders are great for eliminating specific wireless dead spots, for giving your Wi-Fi signal a little more range to reach that far room or giving your Wi-Fi a little oomph to make it to the next floor. A Wi-Fi extender is the perfect solution if you have one room or one section of your house where the internet always seems to cut out. If your existing Wi-Fi router is able to adequately cover most of your house, you may not necessarily need to buy a new one. With so many options for upgrading your home network, like getting a new router or a mesh router, or adding a Wi-Fi extender or powerline extender, how do you know which is the best option for you? Read our full D-Link DAP-1720 Wi-Fi AC1750 Range Extender review. That verticality makes it one of the best Wi-Fi extenders available for getting signal to every floor of a multistory home, making it the perfect choice for anyone who finds their Wi-Fi signal dropping out when they go up or down stairs. Handy features like a built-in Ethernet port that can handle Gigabit speeds, and a physical on/off switch make it a capable tool for extending the reach of your router, but it serves up patchy performance and is so large that it risks blocking adjacent AC outlets.ĭespite some irregular performance, the D-Link DAP-1720 does particularly well when pushing signal to a floor above or below. D-Link's DAP-1720 is easy to set up, provides a convenient mobile app for managing device settings and can help fill a home with Wi-Fi. |
