November 4, 2024 US election news CNN Politics
Harris has made the key battleground of Pennsylvania her priority on Monday with several stops across the state culminating in her final one in the state’s largest city. The adviser pointed to the final convert british pounds to danish kroner NBC News/ Wall Street Journal poll of the 2020 election cycle as example, which showed Biden leading Trump nationally by 10 points among registered voters. It’s important to remember that while news networks like CNN might project a winner when it is clear who will win, the races are not officially certified until later. Certification deadlines vary from state to state, but they all have until December 11, 2024, to complete recounts, if needed, and settle disputes around presidential results. Former President Donald Trump has pointed to the red mirage to back up his baseless allegations of election fraud, when in fact it has been a function of the rise of mail-in voting and the often-peculiar rules about when those ballots can be counted. Republicans in the state had filed a lawsuit to stop the Justice Department from deploying election monitors inside polling locations, but the state indicated Monday that it had reached an agreement with the DOJ to allow the monitors to stay outside.
Georgia’s Gwinnett County expects to surpass 2020 vote totals, officials say
- Precincts 112 and 52, which are in the same physical space, were evacuated for approximately an hour while the bomb threat, which was deemed non-credible, was investigated.
- If Trump loses the election, Trump Media has little to fall back on.
- And social media’s influence on these voters cannot be underestimated, according to Aidan Kohn-Murphy, founder of advocacy group Gen-Z for Change.
- Republican vice presidential candidate JD Vance thanked former President Donald Trump for allowing him to join his campaign.
A broad majority of Harris voters – slightly under 6 in 10 – call democracy their top issue, with about 20% calling abortion their top issue. About half of Trump voters call the economy their top issue, followed by about 20% calling immigration their biggest issue. After the first drop, the official says, the county will post its next batch of votes, which includes Election Day votes, on Wednesday. Tabulations of early ballots in a key county in Arizona are going slower than expected, a county official told CNN.
In that time, the number of registered Republicans has grown by a million and the party surpassed Democrats in the state for the first time in the state’s modern history. The students, who had been waiting in line for several hours, told Walz they were determined to make their voices heard. They expressed their excitement about participating in this election and encouraged their friends and peers to stay in line and cast their vote, the official said. Minnesota Gov. Tim Walz called into a polling station in Pennsylvania to speak to students waiting in line to vote this evening, a Harris campaign official told CNN. Philadelphia’s Mayor Cherelle Parker told local outlets today that she predicts the city’s turnout for Harris to be between 650,000 and 750,000, which would significantly exceed turnout for Biden in 2020, which was around 600,000 votes.
“This isn’t the first time Apache County has had voting issues on Election Day, but this is the worst we’ve ever seen it,” Katherine Belzowski, the assistant attorney general of the Navajo Nation Department of Justice, told CNN. Kelly Sowle, a 63-year-old Michigan voter who is also backing Harris, explained that plus500 scam “respect for women’s rights” is her “number one” issue. The right to abortion is enshrined in the Michigan constitution after voters overwhelmingly supported it in 2022, but Sowle is concerned about new challenges to that right if Trump wins.
Around 10 Georgia polling sites will stay open late due to disruptions from non-credible threats, official says
It comes after US intelligence last month assessed that Russian operatives were behind a fake video purporting to show someone destroying mail-in ballots in Pennsylvania in late October. The word “until” is the most common and formal word to use, while Modern English permits the shortened best trading forex books bnazl form of till for informal writing. But when it comes to til (with or without the apostrophe), English usage guides don’t share the same opinions. The social media site, Reddit, has a subtopic category dedicated to “til”, as do many social networking sites. Knowledge is power so take a few minutes to learn something new. It’s especially interesting to see what historical events occurred on your birthday.
In Nye County, a county clerk says the estimated line is two and a half hours for at least one polling place. After his time at the count center, Johnson told reporters that he had concerns about the validity of the count. Wearing a neon green “election observer” sticker and trailed by a bevy of reporters and Republican election observers, Johnson walked around the hangar-like counting center, looking at the machines and watching the vote count take place.
Trump campaign feels confidence boost from Virginia
Earlier today, Raffensperger said that all of the bomb threats against polling places in Georgia appear to have originated from Russia. US officials continue to say that at least some of the bomb threats made to polling locations in multiple states appeared to originate from Russian email domains. But the investigation is ongoing, and the FBI has yet to publicly confirm that someone in Russia was behind the threats. About 50 miles away in Cambria County, officials have requested that voting time be extended after a “software malfunction” disrupted voters’ abilities to scan their ballots.
Multiple polling places in Nevada had waits of over an hour as polls were scheduled to close at 10 p.m. A large tranche of about 320,000 votes will soon be reported in Gwinnett County, Georgia, a crucial swing state, the elections supervisor in that county told CNN. State officials are urgently reaching out to a large number of young voters to confirm their signatures so their votes can be counted.
“Three voters were mid-vote when it happened and probably about 25 people in line,” said poll watcher Evette Reyes. Michael Osborne knew something was wrong when he pulled up to his polling site Tuesday morning in battleground Georgia, taking in all the EMS and police vehicles around the building. Email addresses can be spoofed, and US officials have not yet confirmed that the emailed threats came from Russia, the sources said. But investigators are looking at the history of the email account’s activity to try to determine who is behind the threats, the sources said.

The most liquid markets, such as blue-chip U.S. stocks, tend to be the largest. The bid-ask spread represents the difference between the highest price buyers are ready to pay for a stock (the bid) and the lowest price sellers will accept (the ask). A narrower spread typically suggests better liquidity, meaning that buyers and sellers are more aligned in their pricing, which helps make transactions smoother. Conversely, a wider spread may indicate lower liquidity, which can complicate the buying or selling of stocks due to larger price differences. Many stocks can be easily bought and sold through brokerage platforms during market hours. They have set time horizons and cannot be sold until the investment term.
Although this will increase the number of shares outstanding, a stock split will divide the company’s stock price and make it more accessible for new investors to buy full shares.

The current ratio is also known as the working capital ratio and seeks to determine a company’s ability to meet its short-term obligations that are due within a year. The higher the ratio, the better a company’s financial health is and the stronger its ability to meet its financial fxtm 2021 review obligations. Still, you’d likely want some liquid assets, so if you face a situation like needing a home repair, you can sell those rather than having to borrow money. Tangible assets, such as real estate, collectibles, fine art, and so on, are considered relatively illiquid since it can take a while to find a buyer at the appropriate price and process/finalize the transaction.

What is the ISM Manufacturing Index and its role as an indicator for the US Economy?
For example, if a company experienced no sales growth, its inventory levels might have remained the same due to a lack of demand. As noted above, the ISM Non-Manufacturing Index (or the Services PMI) provides stakeholders with insight into the state of the nation’s services sector. A diffusion index summarizes whether purchase managers believe the market is expanding, contracting, or staying the same. Survey respondents are broadly diversified across industries based on the North American Industry Classification System (NAICS). The number of survey respondents within each industry varies depending on that industry’s share of the U.S.
Applications
The ISM Manufacturing Index, commonly known as the ISM Manufacturing Purchasing Managers Index (ISM PMI), is a monthly gauge of the level of economic activity in the manufacturing learn how to buy sell or trade bonds sector in the United States versus the previous month. An index of more than 50 indicates an expansion in the manufacturing segment of the economy in comparison with the previous month while a reading of 50 indicates no change and a reading below 50 suggests a contraction of the manufacturing sector. If there’s an increase in demand for manufactured products, purchasing managers respond by increasing orders for production materials and other supplies.

Because unlicensed devices are required to be tolerant of ISM emissions in these bands, unlicensed low-power users are generally able to operate in these bands without causing problems for ISM users. ISM equipment does not necessarily include a radio receiver in the ISM band (e.g. a microwave oven does not have a receiver). The ISM Non-Manufacturing Index and the Services PMI are the same thing. The index, which was previously known as the Non-Manufacturing Index is now known as the Services PMI. The index provides a reading that is based on surveys sent to executives of purchasing and supply companies of more than 400 service companies.
ISM has calculated and published the monthly index since 1931, except for a four-year break during World War II. Survey responses are divided into 16 manufacturing industries, including furniture and related products, computer and electronic goods, apparel and transportation equipment. The Institute of Supply Management is a nonprofit organization for the professional supply management sector. It was established in 1915 with more than 50,000 members in 100 countries. The ISM provides education, certification, development, and research for leaders across various industries.
- Starting in January 2011, the Inventories Index stopped being seasonally adjusted.
- On June 2, 2014, ISM released the ROB and then revised it twice in the span of about two-and-a-half hours, a highly unusual event.
- An index of more than 50 indicates an expansion in the manufacturing segment of the economy in comparison with the previous month while a reading of 50 indicates no change and a reading below 50 suggests a contraction of the manufacturing sector.
- Monitoring the Services PMI can help investors better understand the economic conditions within the U.S.
- In the United States, according to 47 CFR Part 15.5, low power communication devices must accept interference from licensed users of that frequency band, and the Part 15 device must not cause interference to licensed users.
ISM Manufacturing Index Reading
The ISM Non-Manufacturing Index is an index that measures the economic condition and performance of service-based companies. The index is based on surveys sent to purchasing and supply companies of more than 400 services firms. It is part of the Institute of Supply Management’s ISM Report On Business—Manufacturing and Services. As a barometer of the overall economy, the index shows trends in the service sector. The ISM Manufacturing Index is published monthly and is an important leading indicator of the U.S. economy. The reason that this economic indicator is forward-looking is how far ahead purchasing decisions need to be made for future manufacturing needs.
Formally called the Manufacturing ISM Report on Business, the survey is conducted by the Institute for Supply Management (ISM). ISM PMI data is considered to be a leading indicator of economic trends. Not only does the ISM manufacturing index report information on the prior two months, but it also outlines long-term trends that have been building over time based on prevailing economic conditions.
All these data primarily depend on the data collected by the Business Survey Committee surveying the supply management professionals. The committee’s composition is established based on the industry category and each industry’s contribution to the GDP. As a result, the interpretation of an ISM Manufacturing Index of 58 would be that economic activity in the manufacturing sector in the United States expanded compared to the prior month. The ISM Semiannual what does an it security specialist do Report, released in May and December, provides insight into both the manufacturing and non-manufacturing sectors of the U.S. economy.
People in charge of buying stuff for their company are called purchasing managers. Institute for Supply Management is white label solution white label forex trading platform the oldest, and the largest, supply management association in the world. Gross domestic product ( GDP ) is arguably one of the most important economic indicators. Wall Street Indexes rose on Tuesday helped by a surprise US services activity print. Market participants continue to wait with bated breath on the outcome of the US Presidential election.The ISM…
Employment Trends
All the ISM indexes are diffusion indexes and are indicators of month-to-month change. The percent response to the «Better,» «Same,» or «Worse» question is difficult to compare to prior periods; therefore, ISM diffuses the percentages for this purpose. A diffusion index indicates the degree to which the indicated change is dispersed or diffused throughout the sample population. Respondents to ISM surveys indicate each month whether particular activities (e.g., new orders) for their organizations have increased, decreased, or remained unchanged from the previous month.
As an investor, you can use this information to make important decisions about where to invest your money. In the United States, it was also known as the ISM Purchasing Managers Index (PMI), a monthly survey of purchasing managers from around 300 manufacturing companies. The Institute for Supply Management releases the corresponding monthly report, pointing to the economic activity and its direction every month. The Institute for Supply Management’s monthly Manufacturing PMI Report on Business outlines directional trends for several manufacturing indexes.
As such, it is widely followed by economists, analysts, government, business leaders, and supply management professionals. By monitoring the ISM manufacturing index, investors can better understand national economic trends and conditions. When the index is rising, investors anticipate a bullish stock market in reaction to higher corporate profits. The opposite is the case in the bond markets, which may fall as the ISM manufacturing index rises because of the sensitivity of bonds to inflation. The powerful emissions of these devices can create electromagnetic interference and disrupt radio communication using the same frequency, so these devices are limited to certain bands of frequencies.
Тестирование Производительности Баз Данных При Помощи Tsqlt И Sqlquerystress Хабр
Устойчивость подсистемы баз данных требует тщательного планирования, включая определение «точки отказа». Существует объективная необходимость такого тестирования, в первую очередь проверки целостности данных, их достоверности, поскольку в бэкенде хранятся пользовательские данные, и данные необходимые для работы приложения. Чтобы оценить истинное значение метрики, недостаточно ориентироваться на единичное значение — требуется собрать несколько результатов и проанализировать их в совокупности. Один из ключевых инструментов в этой работе — доверительный интервал. Он показывает, насколько близки измеренные значения к их истинному среднему значению и насколько мы можем быть уверены в их стабильности при тестировании на данной нагрузке системы.
Приступая к тестированию БД, персонал QA-департамента должен получить требования из всех релевантных источников, особенно функциональные. Часто бывает малое количество требований, или требования не детализированы. Тестирование БД — достаточно сложная задача, требующая опыта и подготовки. Веб-инструмент сканирования страниц сайтов и проверки уязвимости скриптов и форм что касается инъекций. Обнаруживает ошибки с файлами, уязвимости в базах данных, LDAP и CRLF.
Требования К Нагрузочным Тестам
Если есть какие-либо неиспользуемые хранимые процедуры в базе данных. Если тестировщик хочет внести изменения в структуру таблицы, он / она должен убедиться, что все хранимые процедуры, имеющие эту таблицу, совместимы с этим изменением. На рынке существуют различные инструменты, которые можно использовать для сопоставления объектов в схемах. Требуется найти несопоставленные объекты https://deveducation.com/ в базе данных, такие как таблицы, представления, столбцы и т.
Фактически мы уперлись в ресурсы самого генератора, а не тестируемой системы. Однажды на одном из проектов во время нагрузочного тестирования мы выявили, что на систему подавалась нагрузка, которая не превышала 500 RPS. При этом анализ потребления ресурсов тестовой системой не выявил значительных деградаций, да и потребление ресурсов не превышало 15%.
Тестирование Базы Данных — Целостность Данных
Таким образом, пул подключений и конфиг будут инициализированы только один раз в функции setup и использованы для каждой стадии. Ошибкой будет вызов и исполнение «долгих» функций на стадии setup , так эта стадия имеет свой timeout. По истечению времени, k6 прервёт выполнение функции setup, что может привести к неопределенному результату. Как ранее упоминалось, в Picostress мы вынесли логику создания и заполнения таблиц данными в отдельную команду, которая выполняется вне среды k6. В самом начале файла мы подключаем xk6-модуль, чтобы вызывать его функции внутри сценарного файла.
Для записи и последующего воспроизведения на этапе выполнения автоматизированных скриптов используются специализированные инструментальные средства. По нашему наблюдению, в качестве платформы для создания высоконадежных и высокопроизводительных приложений, российские заказчики часто отдают предпочтение технологиям Oracle. Важными инструментами стресс-тестирования являются бегунок нагрузки, победитель бега и JMeter. Давайте также рассмотрим некоторые интересные инструменты для проверки схем баз данных. GUI обычно уделяется наибольшее внимание членам группы тестирования и разработки, поскольку графический интерфейс пользователя оказывается наиболее заметной частью приложения.

Чтобы нагрузочное тестирование пример получить доступ к важной информации, хакеры могут использовать инструмент взлома пароля или угадать общее имя пользователя / пароль. Эти общие пароли легко доступны в интернете, а также существуют инструменты для взлома паролей. Эти атаки представляют большую угрозу для данных, поскольку злоумышленники могут получить доступ к важной информации из базы данных сервера. Чтобы проверить точки входа SQL-инъекций в ваше веб-приложение, найдите код из базы кода, где прямые запросы MySQL выполняются в базе данных, приняв некоторые пользовательские данные. Логическое резервное копирование базы данных включает резервное копирование логических объектов, таких как таблицы, индексы, процедуры и т. Он выполняет модульное тестирование функций базы данных, триггеров, представлений, запросов SQL и т.
- Целостность базы данных является необходимым условием ее правильного функционирования.
- Она также гарантирует, что все, кто пытается получить доступ к определённым областям сервера базы данных, имеют соответствующую авторизацию.
- Во избежание, базы данных тестируются на производительность; это делается до развертывания приложения, превентивно.
- Ошибкой будет вызов и исполнение «долгих» функций на стадии setup , так эта стадия имеет свой timeout.
- Рассчитано на тестировщиков как с большим опытом в тестировании безопасности, так и на начинающих, которым дали небольшое задание.
Тогда релизы делались не так часто и период выпуска новой версии составлял от four до 6 месяцев. Обновление утилиты генератора нагрузки устранило данный баг, и процессор уже использовался на полную мощность, что позволило получить 2000 RPS с одного генератора. Начинается поиск узкого места и выясняется, что мы мониторили только CPU, RAM и еще несколько базовых метрик только у основной системы. И полностью забыли об остальных, которые задействованы в работе. Например, описание, архитектура, заинтересованные лица будут вам уже известны, если вы будете подключаться на самых ранних стадиях планирования. Вы сможете намного раньше указывать на нюансы, которые могут иметь место в архитектуре приложения.
Как правило, при этом не требуется дополнительной модификации тестовых скриптов, поскольку это зависит в большей степени от используемого инструментария и, в меньшей степени, от тестируемого программного обеспечения. Тестирование белого ящика — это противоположность тестированию черного ящика. При тестировании белого ящика тестировщик полностью понимает внутреннюю структуру и дизайн тестируемого приложения. Тестирование белого ящика иногда называют еще тестированием стеклянного ящика, поскольку тестировщик может наблюдать взаимодействия между модулями (юнитами) в процессе тестирования.
Он включает в себя все компоненты репозитория, которые используются для хранения данных и не изменяются конечными пользователями. Обычно это тестирование выполняют администраторы баз данных с хорошим знанием хранимых процедур SQL и других концепций. Функциональное тестирование — включает проверку функциональности базы данных с точки зрения пользователя.
Проверка серверов баз данных также является важным фактором при структурном тестировании баз данных. Успешное завершение этого тестирования требует владения SQL-запросами. Этот конкретный процесс является проверкой сопоставлений полей с точки зрения конечного пользователя.
Обзор остальных инструментов представлю в виде сводной таблицы 1. К сожалению, ни один не удовлетворил наши потребности полностью. В итоге, бутылочные горлышки — это вызов, который нужно принимать с интересом.
Размер БД бывает очень большим, что тоже следует учитывать при нагрузочном тестировании. Направлено на поиск слабых мест в безопасности, а именно уязвимостей в подсистеме БД, определение степени защищенности данных в БД от злоумышленных действий посторонних лиц. Регулярное и тщательное проведение такого тестирования позволяет достичь высокой степени защищенности БД. Статический анализ кода На рынке существует достаточно широкий выбор инструментов тестирования БД, особенно что касается нагрузочного тестирования. Например, можно проводить тесты по выяснению, на каком количестве пользователей у нас закончится доступный пул соединений к базе данных.
Были созданы в необходимых таблицах в соответствии с бизнес-требованиями. Столбцов внутренней базы данных со столбцами, присутствующими во внешней части приложения. Рекомендации, которые приводятся в данной статье, носят общий характер и не привязаны жестко к той или иной методологии или инструментарию. При проверке учетных данных для входа и безопасности пользователя необходимо учитывать следующее. Нефункциональные тесты проверяют производительность базы под нагрузкой, в стрессовых условиях, и показывают возможности оптимизации.
