I live in KwaZulu-Natal, South Africa, and the only indoor bugs I've experienced issues with are fleas, as I have two cats (and a big garden). This morning, however, I put on a fleece top that had been lying around somewhere, got a lift to the store, and returned to suddenly feel a crawling sensation. I lifted up my shirt to find these tiny bugs crawling all over my upper body. I did some Googling, went upstairs and carefully observed my bedding and bed, however, the only evidence I found was a few newborn fleas / flea larvae (which I intend to deal with today). I should also mention that a flock of wild Egyptian Geese have been raising five goslings in my yard, and they get very close to me when I'm walking outside at times. My house is also not carpeted, it has oregon pine floors throughout. I tried to take a photo of the critters, however, they're very tiny and move very quickly, so it was difficult to get a clear shot. Any advice would be greatly appreciated.


Yes, this is a book louse (order Psocoptera). They feed on all kinds of organic matter, and are very common. Fun fact - they are called "book lice" because they are often associated with old books, feeding on the organic glues in the bindings. (they are also called bark lice - I'm sure you'd know why).

      How to Find a Bug in Application? Tips and Tricks

      I think finding a Blocker Bug like any System Crash is often rewarding! No, I don’t think like that. You should try to find out the bugs that are most difficult to find and those always mislead users.

      Finding such subtle bugs is the most challenging work and it gives you the satisfaction of your work. Also, it should be rewarded by seniors. I will share my experience of one such subtle bug that was not only difficult to catch but was difficult to reproduce also.

      I was testing one module from my search engine project. I do most of the activities of this project manually as it is a bit complex to automate. That module consists of traffic and revenue stats of different affiliates and advertisers. So testing such reports is always a difficult task.

      When I tested this report it was showing the data accurately processed for some time but when tried to test again after some time it was showing misleading results. It was strange and confusing to see the results.

      There was a Cron (Cron is an automated script that runs after specified time or condition) to process the log files and update the database. Such multiple crops are running on log files and DB to synchronize the total data.

      There were two Crons running on one table with some time intervals.

      There was a column in the table that was getting overwritten by other Cron making some data inconsistency. It took us a long time to figure out the problem due to the vast DB processes and different Crons.

      My point is trying to find out the hidden bugs in the system that might occur for special conditions and causes a strong impact on the system. You can find such a bug with some tips and tricks.

      So what are those Tips:

      #1) Understand the whole application or module in depth before starting the testing.

      #2) Prepare good Test Cases before start to testing. I mean give stress on the functional test cases which include the major risk of the application.

      #3) Create sufficient Test Data before tests, this dataset includes the test case conditions and also the database records if you are going to test DB related application.

      #4) Perform repeated tests with the different Test Environment.

      #5) Try to find out the resulting pattern and then compare your results with those patterns.

      #6) When you think that you have completed most of the test conditions and when you think you are tired somewhat then do some Monkey Testing.

      #7) Use your previous Test Data pattern to analyze the current set of tests.

      #8) Try some Standard Test Cases for which you found the bugs in some different application. Like if you are testing input text box try inserting some HTML tags as the inputs and see the output on display page.

      #9) Last and the best trick is to try very hard to find the bug. As if you are testing only to break the application!

      I will include more tips in some coming posts. Meantime you can comment out more tips here.

      What is difference between Performance Testing, Load Testing and Stress Testing?

      What is performance testing?

      Performance testing is the testing, which is performed, to ascertain how the components of a system are performing, given a particular situation. Resource usage, scalability and reliability of the product are also validated under this testing. This testing is the subset of performance engineering, which is focused on addressing performance issues in the design and architecture of software product.

      The primary goal of performance testing includes establishing the benchmark behaviour of the system. There are a number of industry-defined benchmarks, which should be met during performance testing.

      Performance testing does not aim to find defects in the application, it address a little more critical task of testing the benchmark and standard set for the application. Accuracy and close monitoring of the performance and results of the test is the primary characteristic of performance testing.

      For instance, you can test the application network performance on Connection Speed vs. Latency chart. Latency is the time difference between the data to reach from source to destination. Thus, a 70kb page would take not more than 15 seconds to load for a worst connection of 28.8kbps modem (latency=1000 milliseconds), while the page of same size would appear within 5 seconds, for the average connection of 256kbps DSL (latency=100 milliseconds). 1.5mbps T1 connection (latency=50 milliseconds) would have the performance benchmark set within 1 second to achieve this target.

      For example, the time difference between the generation of request and acknowledgement of response should be in the range of x ms (milliseconds) and y ms, where x and y are standard digits. A successful performance testing should project most of the performance issues, which could be related to database, network, software, hardware etc…

      Load testing is meant to test the system by constantly and steadily increasing the load on the system till the time it reaches the threshold limit. It is the simplest form of testing which employs the use of automation tools such as LoadRunner or any other good tools, which are available. Load testing is also famous by the names like volume testing and endurance testing.

      The sole purpose of load testing is to assign the system the largest job it could possible handle to test the endurance and monitoring the results. An interesting fact is that sometimes the system is fed with empty task to determine the behaviour of system in zero-load situation.

      The goals of load testing are to expose the defects in application related to buffer overflow, memory leaks and mismanagement of memory. Another target of load testing is to determine the upper limit of all the components of application like database, hardware and network etc… so that it could manage the anticipated load in future. The issues that would eventually come out as the result of load testing may include load balancing problems, bandwidth issues, capacity of the existing system etc…

      For example, to check the email functionality of an application, it could be flooded with 1000 users at a time. Now, 1000 users can fire the email transactions (read, send, delete, forward, reply) in many different ways. If we take one transaction per user per hour, then it would be 1000 transactions per hour. By simulating 10 transactions/user, we could load test the email server by occupying it with 10000 transactions/hour.

      I am into storage domain and I am doing regression testing on various NAS products, my client always expects to find more and more bugs on daily basis. In regression its very difficult to find the bug. any other way so that find some bugs in the product.

      hello every one,
      is there any tool for manual testing?

      i think HP SPRINTER is there,can any one plz tell me how can i utilyze it.

      Hello,

      Abstract

      Abstract: Invertebrates with specific host species may have a high probability of extinction when their hosts have a high probability of extinction. Some of these invertebrates are more likely to go extinct than their hosts, and under some circumstances, specific actions to conserve the host may be detrimental to the invertebrate. A critical constraint to identifying such invertebrates is uncertainty about their level of host specificity. We used two host-breadth models that explicitly incorporated uncertainty in the host specificity of an invertebrate species. We devised a decision protocol to identify actions that may increase the probability of persistence of a given dependent species. The protocol included estimates from the host-breadth models and decision nodes to identify cothreatened species. We applied the models and protocol to data on 1055 insects (186 species) associated with 2 threatened (as designated by the Australian Government) plant species and 19 plant species that are not threatened to determine whether any insect herbivores have the potential to become extinct if the plant becomes extinct. According to the host-breadth models, 18 species of insect had high host specificity to the threatened plant species. From these 18 insects, the decision protocol highlighted 6 species that had a high probability of extinction if their hosts were to become extinct (3% of all insects examined). The models and decision protocol have added objectivity and rigor to the process of deciding which dependent invertebrates require conservation action, particularly when dealing with largely unknown and speciose faunas.

      Abstract

      Resumen: Los invertebrados con especies huésped específicas pueden tener una alta probabilidad de extinción cuando sus huéspedes tienen una alta probabilidad de extinción. Algunos de estos invertebrados tienen una mayor probabilidad de extinción que sus huéspedes, y bajo algunas circunstancias, acciones específicas para conservar al huésped pueden ser perjudiciales para el invertebrado. La incertidumbre sobre el nivel de especificidad de huéspedes de una especie de invertebrado es una limitación crítica para la identificación de tales invertebrados. Utilizamos dos modelos de amplitud de huésped que incorporaron explícitamente la incertidumbre en la especificidad de huéspedes de una especie de invertebrado. Diseñamos un protocolo de decisión para identificar acciones que pueden incrementar la probabilidad de persistencia de una determinada especie dependiente. El protocolo incluyó estimaciones a partir de los modelos de amplitud de huéspedes y los nodos de decisión para identificar especies coamenazadas. Aplicamos los modelos y el protocolo a datos sobre 1055 insectos (186 especies) asociados con dos especies de plantas amenazadas (de acuerdo con el Gobierno Australiano) y 19 especies de plantas que no están amenazadas para determinar si el algún insecto herbívoro tiene el potencial de extinguirse si la planta se extingue. Con base en los modelos de amplitud de huéspedes, 18 especies de insectos tuvieron alta especificidad de huéspedes con las especies de plantas amenazadas. De estas 18 especies, el protocolo de decisión resaltó a 6 especies que tuvieron una alta probabilidad de extinción si sus huéspedes se extinguieran (3% de todos los insectos examinados). Los modelos y el protocolo de decisión han añadido objetividad y rigor al proceso de decidir que invertebrados dependientes requieren acciones de conservación, particularmente cuando se trata de faunas especiosas desconocidas.


      4 Ways To Identify Beneficial and Harmful Insects In Your Lawn

      While some pests may have a more obvious look, comparing beetles to beetles may get a little confusing. To help you determine which is which, take a look at these steps to identifying the insects in your lawn:

      1. Educate

      The first step is educating yourself on the insects that are most common in your area. Familiarize yourself with the appearance of beneficials and pests—but don’t stop there! The larvae of these insects typically look completely different than adult insects.

      For example, ladybug larvae are small, black and yellow, spiny insects. At a glance, you might think these are harmful insects and attempt to remove them from your lawn or garden. This would be the worst thing you could do though! Ladybug larvae, like many other beneficial larvae, eat significantly more pests than adult insects.

      So, get to know the larvae too! Learn what they look like, where they’re likely to live and what they eat.

      2. Observe

      Next, observe the insects living in your lawn and garden. What do they look like? What are they doing? Is there one, or are there multiple? Multiple insects may indicate an infestation, so it’s important to note how many insects are present.

      3. Identify

      After observing insects, and educating yourself on the appearance of beneficials and pests, you should be able to identify the insects around your home.

      From there, you’ll be able to find the best way for controlling the insect population, or take the next steps to eradicate pests from your lawn.

      Here at Killingsworth, we believe in organic pest control. If you identify pests in your lawn, garden, or home, check out these organic pest control tips from our experts.

      4. Contact

      If you are unable to identify the insects in your lawn, contact your local pest professional . They will be able to identify if the insect is a beneficial or a pest and recommend next steps if necessary. We suggest taking a photo of the insect in question so that your pest expert knows exactly what you’re dealing with.


      Edible Bugs You Probably Want to Avoid Eating

      These bugs are edible, but either harder to find or riskier to collect and eat. You may want to exercise caution before eating these—or at least know what you’re getting yourself into.

      Slugs and Snails

      While their flesh is benign, there’s a high enough likelihood that they’ve fed on something toxic—like poisonous plants or mushrooms—to make eating them inadvisable. The ones that you eat in a restaurant have been fed safe-to-eat plants the people preparing them know exactly what those snails were eating. The same can’t be said of an in-the-wild snail’s diet. If you wild snails or slugs, you risk contracting rat lungworm, which can turn into eosinophilic meningitis (causing severe brain and nervous system damage). These diseases usually hide in the digestive tract of the slugs and snails, so cooking them won’t necessarily guarantee that they’re disease-free system. If snails are your only meal option, you can also feed them plants you know aren’t poisonous for a week before eating them. Then be sure to cook them thoroughly.

      Tarantulas

      Fun fact: fried spider is a delicacy in Cambodia. Remove as much hair as you can, and don’t eat the fangs. If you cook them, curled legs are an indicator of how done they are and how well cooked the insides are. One of the most common edible spiders is the Thai zebra spider, but it is venomous and aggressive.

      Bees and Wasps

      Cut off the stingers and legs. Cook well. But be forewarned: These fliers are dangerous to catch. If risking stings is worth it (or you don’t have another choice), you can try plugging the hive, and then smoke the whole thing with some sort of improvised torch to kill everything inside. These are on the “honorable mention” list only because they’re hard to catch and will attack you without remorse. That said, bee larvae can be eaten, and they’re less likely to fight back.

      Cut off the stingers and cook well. Andy Murray / Flickr

      Caterpillars

      Some are toxic, like the giant silkworm moth and the puss caterpillar. Bright ones and hairy ones tend to be toxic, but that isn’t a set-in-stone rule. So either do some research about the area you plan to be stranded in or proceed with extreme caution. If you’re stranded and looking to survive, this probably isn’t the best gamble.

      Which Bugs Shouldn’t I Eat and Why?

      Bug Don’t Eat It Because…
      Slugs and Snails You don’t know what they ate. They love eating poisonous plants. Cooking them doesn’t boil out this poison. They also carry rat lung worm (and it’s as awful as it sounds).
      Tarantulas They have no qualms about jumping on you and attacking you. They’re aggressive.
      Bees and Wasps These guys will kamakaze you. You could get stung by them. Other insects are likely more readily available, and they’re definitely less likely to attack back
      Caterpillars Some are toxic, and unless you know which is which beforehand, now is probably not the time to guess wildly.

      Telltale Signs a Bug Might Kill You

      While the majority of bugs are safe to eat, there are a few precautions you should take:

      • Avoid Bright Colors: Don’t eat any insects that are brightly colored their coloration is a warning to predators that they’re toxic. That even goes for the insects on this list.
      • Avoid Hairy Things: Avoid hairy bugs there may be stingers nestled in the fuzz.
      • Avoid Smelly Things: Also avoid any bugs that have a potent smell (except, paradoxically, stinkbugs).

      When in doubt: If you are ever in doubt about an insect’s edibility, cut off a tiny, cooked piece of it, swallow it, and wait a few hours. If you don’t develop any symptoms, eat a larger piece and wait again. If nothing happens, it’s probably fine.

      No bug sushi: We can’t stress this enough. Whenever possible, you should cook your insects before you eat them. They may carry parasites or harmful bacteria that cooking will kill, and it improves flavor and makes the nutrients more digestible.
