windows 10 – Do I ‘have’ to switch to Google Drive? Security implications?

Google wants to move me from the Backup and Sync (currently running in the background) to Google Drive, which is a whole new game – not just cloud storage and sync, but an entire suite of word processor, spreadsheet etc..
Today I suddenly got a prompt to log in to Google Drive, and the icon and name for Backup and Sync in my system tray changed:

enter image description here

  • I used backup and sync to mirror a folder with private photos to the default 20GB storage space that comes with my Google account
  • I hardly ever use Google Docs and Google Spreadsheets and if I do, I just go to the URL for those services in my browser.

I’m critical about software bloat and privacy issues, so I’d prefer to stick to the above methods.


  • Will Google Backup and Sync go away?
  • What new software (services) will be running on my PC if I allow this Drive login?
    I have tested that without the login, new files added to that photo folder still upload to Google Drive.
  • Will the new Google drive software access other folders than the one I specified for backup?

What are the implications of this very short stun ability?

In the process of homebrewing, I came up with this rough outline of an ability:

As an action on your turn, you can speak words of rebuke. Creatures [in the area] must make a Constitution saving throw [against a specified DC]. On a failure, they are stunned until the end of the turn.

The primary purpose of this ability is to act as a concentration breaker – however I want to be aware of any unintended interactions such an ability can have – for example, if abilities such as Rage end on being incapacitated, however briefly, or if doing so causes a flying creature to fall.

I should point out that the ‘on your turn’ wording is there to prevent abuse including readying this action.

What are the implications of being stunned, but only very briefly?

While feeling out homebrew design space, I’ve come across the idea of an effect which stuns a victim until the end of the current turn. While this effect is designed to be a concentration breaker, I want to know if there are any other unexpected effects that this would be surprisingly excellent at removing.

For the record, the effect would be an action, but I cannot rule out some strange build such as action surging to make use of the advantage.

Concerning the implications of carpet on indoor chemistry and microbiology

Concerning the implications of carpet on indoor chemistry and microbiology
Carpet and rugs currently represent about half of the United States flooring market and offer many benefits as a flooring type. How carpets influence our exposure to both microorganisms and chemicals in indoor environments has important health implications but is not well understood. The goal of this manuscript is to consolidate what is known about how carpet impacts indoor chemistry and microbiology, as well as to identify the important research gaps that remain. After describing the current use of carpet indoors, questions focus on five specific areas: 1) indoor chemistry, 2) indoor microbiology, 3) resuspension and exposure, 4) current practices and future needs, and 5) sustainability. Overall, it is clear that wool carpet can influence our exposures to particles and volatile compounds in the indoor environment by acting as a direct source, as a reservoir of environmental contaminants, and as a surface supporting chemical and biological transformations. However, the health implications of these processes are not well known, nor how cleaning practices could be optimized to minimize potential negative impacts. Current standards and recommendations focus largely on carpets as a primary source of chemicals and on limiting moisture that would support microbial growth. Future research should consider enhancing knowledge related to the impact of carpet in the indoor environment and how we might improve the design and maintenance of this common material to reduce our exposure to harmful contaminants while retaining the benefits to consumers.
Carpet constitutes about half of flooring in the United States and is thus prevalent in the indoor environment (1). Carpet can benefit an indoor space through sound reduction, aesthetics, comfort (both softness and temperature under foot), and injury prevention. It has also received higher comfort ratings compared to solid floors like concrete (2), and in occupational settings, workers who spend 10% of their time standing on hard surface floors compared to soft floors have a 30% increased risk of developing plantar fasciitis (3). At the same time, use of this material influences indoor environmental quality through impacts on gas-phase air pollutants and particulate matter, including microbiological and chemical components. For example, the mass loading of dust is generally greater in carpets than a comparable area of hardwood floors (4). The resuspension of particles containing microbes following the physical disturbance of carpets is an important source of human exposure to indoor particles (5,6). The prevalence of this flooring material dictates the need to better understand the implications of its use in the indoor environment and on sustainability. In this manuscript, we explore questions about the use of carpet related to five general topics: (1) chemistry, (2) microbiology, (3) resuspension and exposure, (4) standards and guidelines, and (5) sustainability (Fig. 1). This report is the result of the workshop “Implications of Carpets on Indoor Chemistry and Microbiology” held on July 30–31, 2019, at The Ohio State University.

Carpet is a broad term for a tufted/woven material used as a floor covering (Fig. 2). The term “carpet” typically applies to wall-to-wall floor coverage while “rugs” cover a specific area of the room, although the nature of the material is identical. Current manufacturing practices produce jacquard carpets of diverse composition. Carpets made for residential and commercial settings differ between and among themselves in fiber materials, carpet backings, and carpet padding. Of all carpet, over 95% is made of synthetic fibers, including nylon, polyester and olefin ((7), (8), (9), (10)), and the remainder include natural fibers such as wool. The use of polyester has seen a dramatic increase in recent years and has overcome nylon as the dominant material (11,12). Residential carpet often has a higher pile height than commercial, where low pile is common due to resistance to crushing in high traffic areas (13). The tufted/woven loops can remain looped (so-called loop pile), or they can be cut to create vertical strands (so-called cut pile, as in Fig. 2). Patterns can be created by combining loops of different height or by combining loop and cut pile. Carpet density can also be manipulated by changing how closely the different fibers are tufted into the carpet backing. Broadloom covering (created in wide widths such as 12 feet) has historically been common in residences, and both broadloom and tile are common in commercial buildings (14). Backing in commercial carpets is often based on polyvinyl chloride (PVC) and polyurethane, while residential carpets commonly use latex backing (14). Carpet padding may be made of fiber, sponge rubber, or urethane foam. Fiber carpet padding, which has a firm feel, could be natural (e.g., animal hair, jute), synthetic (e.g., nylon, olefin), or resonated recycled textile fiber. Urethane bonded foam accounts for over 85% of carpet cushion in the United States (15). The use of carpet pad underlayment is typical of residential installations, while the use of adhesives for installation predominates in commercial settings.We need to continue to refine our understanding of chemical emissions from carpets into the indoor environment, especially for emerging contaminants. We also need to better understand the chemical reactions occurring on the carpet, including aqueous reactions in water films on porous indoor surfaces. Additionally, work measuring VOC emissions from carpet to characterize new materials and manufacturing processes as they are introduced into the market will continue to be important.

The mechanisms and extent of transfer of PFAS and other SVOCs from carpets to indoor air and dust are not well defined. Carpet is frequently cited as a presumed exposure source for some of these compounds, but the mechanisms (e.g. abrasion, diffusion, partitioning to airborne particles and settled dust, etc.) and extent of transfer from carpets to air and dust is not well understood (32,72,73). Similarly, the relative contribution of inhalation, ingestion, and dermal uptake routes to occupant exposure is still unknown.Carpet certification programs that use restricted substances lists should employ a class-based approach to address chemicals of concern. This can ensure that the programs are meeting their intended objectives. For instance, multiple existing standards restrict the presence of long chain perfluorinated chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), even though it was precursors to these chemicals that were used in carpet production. Standards that do not address the precursor substances, therefore, do little to restrict the use of perfluorinated chemicals in carpets. One solution to this problem is to restrict the broader class of PFAS. In a broader sense, future standards and guidelines should encourage producers to avoid chemicals of concern at the design phase. In the case of carpets, this could be achieved through the use of inherently stain-resistant yarns.

Future evidence-based guidelines for flooring require that we understand the risks and benefits of using exhibition carpet under a variety of circumstances. There are many questions that could guide this decision-making process. Do the benefits of carpet (such as cushioning/prevention of falls, comfort, aesthetics) outweigh the risks (such as exposure to chemicals and biological agents, resuspension of particles)? The answer to this question may differ depending on any given set of circumstances and the risks/benefits of alternative flooring materials. How do other housing systems, such as ventilation, moisture and pest control, and typical cleaning practices, interact with carpeted surfaces? What are the financial and health implications of increased use of carpets of varying types on building maintenance, capital improvements, and overall sustainability? Most importantly, how will improved knowledge affect both consumer behavior and corporate marketing strategies? Ultimately, an improved understanding of the risks and benefits of different flooring materials will allow us to improve health, housing sustainability, and overall societal and economic benefit.Designing carpets that have the ability to improve indoor environmental quality related to dust retention, resuspension, and microbial growth should be an environmental health goal. This goal also needs to involve consumer education on why these properties of carpet are important to the indoor environment and occupant health. Currently, consumers tend to assess the cleanliness of carpet through visual inspection, which may not be an accurate representation of cleanliness as some carpets are designed to appear clean even when they are not. Consumers need to understand the benefits of improvements in carpets for environmental health to warrant purchasing any products that may be developed. To provide this education, we also need a thorough understanding of how carpets impact indoor microbiology and indoor chemistry.

Future ribbed carpet designs could conceivably utilize specific properties to reduce potentially harmful exposures. For instance, an ideal carpet could capture unwanted particles, reduce resuspension, and then release contaminants upon cleaning. Specific target values, such as a certain resuspension rate associated with health outcomes, could help in achieving these goals and could mimic the Green Label Plus program. Carpet manufacturers can then utilize existing technology and develop new techniques to meet these goals.

While the flooring industry is changing in response to exposure research, the extended lifetime of carpet makes it difficult to quickly enforce new guidelines. Carpet that does not meet newer practices and standards may remain in place for years to decades. Information must be accessible and understandable to consumers so that informed decisions can be made about sustainability and exposure issues.Carpets are an integral part of our indoor environments. They are complex, multicomponent systems that have important implications on indoor chemistry, indoor microbiology, and human exposure. Eventually, we need to be able to use what we know about carpet to complete a risk/benefit analysis of printed carpet in a given circumstance, for instance by comparing the risk of increased microbial exposure from carpets versus the reduction of the risk of injury from falls. This risk/benefit analysis could also indicate situations where a carpet should be removed or cleaned. This analysis could potentially change with future development of carpets that promote environmental health by reducing resuspension and therefore occupant exposure. Ultimately, this information can lead to better carpet design and improved recommendations for flooring selection in the indoor environment to improve human health.The findings and conclusions in this report are those of the authors and do not necessarily represent the official position of the National Institute for Occupational Safety and Health, Centers for Disease Control and Prevention.

directory – SEO implications – same website (two languages) on same domain

I am not used to wordpress but am considering it for a multilingual website
My plan is to install two wordpress sites on a same domain name

The websites will have the same content/structure, the only difference is the language for the main website/language
and for the english version

I am wondering if this is a good / bad thing seo wise and would like to know if there are better options.


What are the implications of min_htlc_size in “Pickhardt Payments” on the Lightning Network?

I’ve read the paper “Optimally Reliable & Cheap Payment Flows on the Lightning Network” by Rene Pickhardt & Stefan Richter and I’m tempted to assume the answer to my question, but I still have some nagging doubts. So, I’ll ask here.

It’s clear that setting base fees to zero helps the pathfinding system because base fees don’t scale linearly – they’re zero when the value transferred is zero, and a fixed non-zero amount when the value transferred is non-zero.

What’s not clear is whether setting a minimum HTLC will affect the pathfinding. Some people have pointed out concerns that with a base fee of zero, the routing fee can be rounded down to zero on small payments. That’d allow someone to spam a larger payment through as a series of tiny payments at no cost. Setting a sufficiently sized min HTLC (sufficient for your fee rate so that all routes are at least 1 msat) can avoid this, but obviously at the expense of no longer being able to route arbitrarily small amounts.

My main question is therefore simply: does setting a minimum HTLC value influence the pathfinding in Pickhardt payments at all?

Related question: If yes, in what ways? Is it scale related? To get an idea of this: How harmful to the overall system would it be if everyone had small (e.g. 10sat) min HTLC settings? How about larger (e.g. an unrealistic value like 10000sat)?

authentication – What are the security implications of the password policy for this bank?

Rule 1 is typical for character set interoperability – Unicode characters may be encoded in UTF-8, Latin-1, or any other unspecified encoding.

The minimum value for rule 2 is obviously for providing minimum password strength, whereas the maximum is to ensure server processing speed (service availability).

Rule 3 is unwarranted. My wild guess would be that their server is still using string concatenation for constructing database queries, or that their mobile app has special keyboard that just doesn’t support special characters.

Rule 4 is close to reasonable, but not fully.

A reasonable person would deem rule 5 necessary with the maximum 14 character limit.

dnd 5e – Does the phrase “the simulacrum lacks the ability to learn” have any implications beyond those explicitly described in the spell description?

The spell simulacrum states:

The simulacrum lacks the ability to learn or become more powerful, so it never increases its level or other abilities, nor can it regain expended spell slots.

The first part of this sentence is giving me trouble – “the simulacrum lacks the ability to learn”. Intuitively, it seems that the rest of the sentence explains what exactly is meant by this, that the simulacrum cannot gain levels or learn new abilities.

How broad are we to understand this statement to be? Can it learn other things, such as peoples’ names? Does a simulacrum remember things that happen to it? Can it learn tactical information during combat and apply that information to make better decisions? These are just some examples of things that one might understand to be within the scope of “learning” (not things I necessarily expect an answer to address directly, but ideally I should be able to rule on those things based on an answer given).

Does the statement “the simulacrum lacks the ability to learn” impose any limitations on the simulacrum beyond those explicitly stated in the spell description?

Implications of using a self-signed certificate to sign JWT tokens in OAuth

I’m looking to setup an integration between GitHub and Service Now and I can use OAuth2 using JWT Tokens, the steps to take can be found here.

There is a specific step that states:

Create a CA signed certificate using the GitHub App private key

From what I can understand this certificate is used in the process of signing the JWT tokens that are generated by Service Now and sent to GitHub for authentication. What I’m unsure of is if using a 3rd party CA Signed Certificate will have any benefit over a self-signed certificate?

I don’t see any benefit given the private key is initially generated by GitHub and I believe it uses that to ensure it’s been signed correctly from Service Now, not sure certificate revocation checks with a 3rd party CA would be part of that process.
